How dentistry has developed over the last 300 years

When you visit a modern dental surgery, its hard to imagine the challenges of dental treatment without all the latest technology.

Yet specialists have been taking care of peoples teeth for thousands of years.

Here are some of the key developments over the last 300 years.

1723: French surgeon Pierre Fauchard – credited as being the father of modern dentistry – publishes the first book to describe a comprehensive system for the practice of dentistry.

1760: John Baker, the earliest medically-trained dentist to practice in America, immigrates from England and sets up practice.

1790: John Greenwood adapts his mothers foot treadle spinning wheel to rotate a drill.

1790: Josiah Flagg, a prominent American dentist, constructs the first chair made specifically for dental patients.

1832: James Snell invents the first reclining dental chair.

1841: Alabama enacts the first dental practice act, regulating dentistry in the United States.

1844: Horace Wells, a Connecticut dentist, discovers that nitrous oxide can be used as an anesthesia and successfully uses it to conduct several extractions in his private practice.

1880s: The collapsible metal tube revolutionizes toothpaste manufacturing and marketing.

1890: Willoughby Miller notes the microbial basis of dental decay in a book which started a world-wide movement to promote regular toothbrushing and flossing.

1896: New Orleans dentist C. Edmond Kells takes the first dental x-ray of a living person in the U.S.

1938: The nylon toothbrush, the first made with synthetic bristles, appears on the market.

1945: The water fluoridation era begins when the cities of Newburgh, New York, and Grand Rapids, Michigan, add sodium fluoride to their public water systems.

1950s: The first fluoride toothpastes are marketed.

1960: The first commercial electric toothbrush, developed in Switzerland after World War II, is introduced in the United States. A cordless, rechargeable model follows in 1961.

Why its not inevitable that youll lose your teeth as you get older

Advancements in dental techniques and the increased focus on preventive dentistry means older adults are keeping their natural teeth longer than ever before.

A survey by the National Institute of Dental and Intracranial Research showed that the rate of toothless in the 55 to 64 age group has dropped 60 percent since 1960.

Whatever your age, its important to practice good oral hygiene at home and to visit your dentist regularly. A few simple steps can help you maintain good oral health throughout your life.

Plaque, the sticky, colorless layer of bacteria that causes tooth decay and gum disease, can build up quickly on the teeth of older adults, particularly when they neglect oral hygiene. This can increase the risk for tooth decay and periodontal disease.

So its important to brush your teeth twice a day with fluoride toothpaste, and clean between your teeth daily with floss or interdepartmental cleaners.

Regular dental checkups are also an important part of caring for your teeth.

This can help you save your teeth and gums and prevent other dental problems. It will save you time and money in the long-run as well.

The facts about oral cancer

Oral cancer is not as well known as other types of cancer but it can represent a life-threatening risk if not identified early.

– It strikes an estimated 35,000 Americans each year
– More than 7,500 people (5,200 men and 2,307 women) die of these cancers each year
– More than 25% of Americans who get oral cancer will die of the disease
– On average, only half of those diagnosed with the disease will survive more than five years
– African-Americans are especially vulnerable; the incidence rate is 1/3 higher than whites and the mortality rate is almost twice as high

Although the use of tobacco and alcohol are risk factors in developing oral cancer, approximately 25% of oral cancer patients have no known risk factors.

There has been a nearly five-fold increase in incidence in oral cancer patients under age 40, many with no known risk factors.

The incidence of oral cancer in women has increased significantly, largely due to an increase in women smoking. In 1950 the male to female ratio was 6:1; by 2002, it was 2:1.

The best way to prevent oral cancer is to avoid tobacco and alcohol use.

Unusual red or white spots can form in and around the mouth. These are often harmless but they can be cancerous or per-cancerous.

Identifying and removing these early enough is a major factor in reducing the incidence of cancer.

So knowing the risk factors and seeing your dentist for regular examinations can help prevent this deadly disease.

Whats involved in getting a dental implant?

Dental implants are increasingly popular as a way to replace missing or damaged teeth.

Their great advantage is that they look natural and feel secure helping you to restore your smile and eat more easily.

Implants are an ideal solution for many people but they are not an option for everyone.

Placing implants requires some surgery so patients must be in good health, have healthy gums and have adequate bone to support the implant.

They must also be committed to taking action to maintain their oral hygiene and to visiting the dentist regularly.

The process for placing implants is as follows:

First, surgery is performed to place the anchor. This can take up to several hours. Following the surgery, you may need to wait up to six months for the bone to grow around the anchor and firmly hold it in place. Sometimes follow up surgery is required to attach a post to connect the anchor to the replacement teeth. Alternatively, the anchor and post may already be attached and are placed at the same time.

After the gums have had several weeks to heal, the next step is to fit specially-made artificial teeth to the post portion of the anchor. This can take a few weeks to complete as several fittings may be required.

Implant surgery can be done either in a dental office or in a hospital, depending upon a number of factors. A local or general anesthetic may be used. Usually pain medications and, when necessary, antibiotics are prescribed.

After your implants are fitted, your dentist will give you tips and advice on maintaining your oral hygiene.

Your dentist can help you decide whether you would be a good candidate for implants.

Should you be concerned about thumbsucking?

Some children suck on their thumbs and parents often wonder if it is harmful.

Sucking on something is a child’s natural reflex. It can help them feel more secure so they start to suck on their thumbs, fingers, pacifiers or other objects.

Since thumbsucking is relaxing, it may also help them sleep.

However, after the permanent teeth come in, sucking may cause problems with the proper growth of the mouth and the alignment of teeth. It can also cause changes in the roof of the mouth.

Whether or not dental problems will result depends on the intensity of the sucking.

A child who vigorously sucks their thumb is more likely to have difficulties than one who rests their thumb passively in their mouth. Young children who suck their thumbs aggressively may even cause problems with their baby teeth.

If you notice changes in your child�s primary teeth, consult your dentist.

Usually children will stop sucking their thumbs between the ages of about two and four. They should have ceased sucking by the time the permanent front teeth are ready to erupt.

If your child is continuing to suck their thumbs, here are some tips:

– Praise them for not sucking, instead of scolding them when they are
– If they are sucking because they feel insecure, focus on correcting the cause of the anxiety
– For older children, involve them in choosing the method of stopping

If necessary, your dentist can help by encouraging the child and explaining what could happen to their teeth if they do not stop sucking.

How to make your smile brighter

Your smile makes a huge difference to what people think about you and how you feel about yourself.

And there are many options available to help you improve the look and brightness of your smile, including:

In-office bleaching: During chair-side bleaching, the dentist will apply either a protective gel to your gums or a rubber shield to protect the oral soft tissues. A bleaching agent is then applied to the teeth, and a special light may be used to enhance the action of the agent.

At-home bleaching: There are several types of products available for use at home, which can either be dispensed by your dentist or purchased over-the-counter. These include peroxide bleaching solutions, which actually bleach the tooth enamel. Peroxide-containing whiteners typically come in a gel and are placed in a mouth guard.

Whitening toothpastes: All toothpastes help remove surface stain through the action of mild abrasives. “Whitening” toothpastes include special chemical or polishing agents that are more effective at removing stains. However, unlike bleaches, they don’t alter the intrinsic color of teeth.

Start by speaking to your dentist. He or she will tell you if whitening procedures would be effective for you as whiteners may not correct all types of discoloration.

Periodontal disease: what it is and how to avoid it

Periodontal disease is an infection of the tissues that support your teeth.

There is a very slight gap (called a sulcus) between the tooth and the gum.

Periodontal diseases attack this gap and cause a breakdown in the attachment of the tooth and its supporting tissues.

When the tissues are damaged, the sulcus develops into a pocket and, as the disease gets more severe, the pocket usually gets deeper.

The two major stages of periodontal disease are gingivitis and periodontitis.

Gingivitis is a milder and reversible form of periodontal disease that only affects the gums. Gingivitis may lead to periodontitis, which is a more serious, destructive form of periodontal disease.

There are several factors that have been shown to increase the risk of developing periodontal disease:
– Systemic diseases such as diabetes
– Some types of medication
– Crooked teeth
– Bridges that no longer fit properly
– Fillings that have become defective
– Smoking
– Pregnancy

And there are a number of warning signs that can suggest a possible problem:
– Gums that bleed easily
– Red, swollen, tender gums
– Gums that have pulled away from the teeth
– Persistent bad breath or taste
– Permanent teeth that are loose or separating
– Any change in the way your teeth fit together when you bite
– Any change in the fit of partial dentures

However, its also possible to have periodontal disease with no warning signs.

Its therefore important to have regular dental checkups and periodontal examinations.

If you have developed periodontal disease, the treatment will depend on how far it has progressed.

You can take steps to prevent periodontal disease from becoming more serious or recurring.

Good dental hygiene practices such as brushing twice a day, cleaning between your teeth, eating a healthy diet and having regular visits to the dentist will make a huge difference.

What to do if you have problems with your dentist

Choosing the right dentist for your needs is an important part of giving yourself the best oral health possible.

Sometimes you may find that things are not working out for the best and it’s important to take steps to resolve any problems rather than just put off your dental care.

First, talk to your dentist about any concerns. They will probably be able to accomodate your needs if you tell them what you are looking for.

In some situations, you may feel that you want to look around at alternative options – maybe there are other dentists who meet your needs better, taking into account factors such as location, office hours, fees and emergency arrangements.

If you are comparing fees, ask for estimates on full-mouth x-rays and a preventive dental visit that includes an oral exam and tooth cleaning.

If you have any doubts about treatment your dentist has recommended, it may be a good idea to set your mind at rest by getting a second opinion from another dentist.

However, even in the best dentist-patient relationship, problems can sometimes occur. If your dentist is not able to resolve your concerns, you can contact your state or local dental association.

They have established systems of peer review that provide an impartial and easy way to resolving misunderstandings regarding the appropriateness or quality of care.

If you are not completely staisfied with the dental treatment you are getting, it’s important ot take steps to put it right – whether you sort it out with your own dentist or find another one.

Diagnosing jaw problems and pains – TMD and TMJ

More than fifteen percent of American adults suffer from chronic facial pain.

Common symptoms can include pain in or around the ear, tenderness of the jaw, clicking or popping noises when opening the mouth or even head and neck aches.

There are two joints and several jaw muscles which make it possible to open and close the mouth. They work together when you chew, speak, and swallow.

These structures include muscles and ligaments, as well as the jaw bone, the mandible (lower jaw) with two joints, the TMJs.

The TM joint is one of the most complex joints in the body. Located on each side of the head, these joints work together and can make many different movements, including a combination of rotating and gliding action when chewing and speaking.

Several muscles help open and close the mouth. They control the lower jaw (mandible) as it moves forward, backward, and side-to-side.

Both TM joints are involved in these movements. Each TM joint has a disc between the ball and socket. The disc cushions the load while enabling the jaw to open widely and perform rotating and translocational movements.

Any problem that prevents this complex system of muscles, ligaments, discs and bones from working together properly may result in a painful TMJ disorder.

If you are suffering from this type of pain, your dentist can help identify its source with a thorough exam and appropriate x-rays.

Often, the problem is a sinus or toothache or it could be an early stage of periodontal disease.

But for some pain, the cause is not so easily diagnosed.

The pain could be related to the facial muscles, the jaw or temporomandibular joint, located in the front of the ear.

Treatments for this pain may include stress reducing exercises, muscle relaxants, or wearing a mouth protector to prevent teeth grinding.
They’ve been successful for many and your dentist can recommend which is best for you.

Should you be concerned about thumbsucking?

Some children suck on their thumbs and parents often wonder if it is harmful.

Sucking on something is a child’s natural reflex. It can help them feel more secure so they start to suck on their thumbs, fingers, pacifiers or other objects.

Taking steps to stop oral cancer before its too late

Oral cancer hits more than 30,000 Americans every year but you can minimize the risk by taking steps to ensure its caught early enough.

The first indications of oral cancer may be a very small, but dangerous, oral spot or sore that you are not even aware of.

In a routine examination, your dentist will carefully examine the inside of your mouth and tongue.

If they notice a flat, painless, white or red spot or a small sore, this may be completely harmless. But harmful spots or sores often look the same as harmless ones.

To ensure that a spot or sore is not dangerous, your dentist may choose to perform a simple test, such as a brush test. This collects cells from the lesion which can them be analyzed.

Any positive results from a brush test must usually be confirmed by a biopsy before deciding the next step.

If precancerous cells are found, the lesion can be surgically removed if necessary during a separate procedure.

When caught early enough, the chances of preventing the cancer developing are high but only half of those diagnosed survive more than five years.

Thats why regular dental examinations are so important for your overall health and not just to have good teeth.

How Invisalign can replace metal braces

The Invisalign system is a series of clear, thin, mouthguards that fit over the teeth and can gradually straighten them.

These have been called invisible braces as they can be an effective alternative to metal braces in some circumstances.

The big advantage of Invisalign is much improved appearance and comfort.

Invisalign mouthguards can be removed during eating and when brushing and flossing. As traditional braces may trap food and plaque, this is another major benefit of Invisalign.

While the system has advantages, it also has some drawbacks.

For example, it is more expensive – costing 25-50 percent more than metal braces.

Also the fact that you remove the mouthguards more often means that you may forget to wear them and it could take longer for you to achieve the desired results.

Invisalign is better suited to some people than others – for example, it may be particularly suitable for adults who have slight to moderate spacing or crowding of their teeth.

Your dentist will be able to tell you if you might be a suitable candiate for Invisalign.

You will get more detailed advice from an orthodontist who has been certified in the Invisalign system.

The power of panormaic x-rays

X-rays are extremely valuable for helping dentists identify issues that may not show up on normal oral examination.

The three most common types of dental X-rays are the bitewing, periapical and panoramic X-rays.

Panoramic X-rays give a broad overview of the entire mouth – supplying information about the teeth, upper and lower jawbone, sinuses, and other hard and soft tissues of the head and neck.

Unlike other X-rays, where the film is placed inside the patients mouth, the panoramic film is contained in a machine that moves around the patient’s head. So they are very easy to use.

Panoramic X-rays are often used to check wisdom teeth but they will also reveal deep cavities and gum disease. They are also useful to help patients with past or present jaw problems or those who require full or partial removable dentures, dental implants, or braces.

They can also be valuable in assisting people who are suspected of having oral cancer or have had recent trauma to the face or teeth.

Panoramic X-rays play an important role in thorough dental examinations and are recommended at least every five years or so for most patients.

How older adults can handle dry mouth and taste problems

Reduced saliva flow that results in a dry mouth is a common problem among older adults.

It is caused by certain medical disorders and is often a side effect of medications such as antihistamines, decongestants, pain killers and diuretics.

Some of the common problems associated with dry mouth include:
– Constant sore throat
– Burning sensation
– Problems speaking
– Difficulty swallowing
– Hoarseness or dry nasal passages

Left untreated, dry mouth can damage your teeth. Without adequate saliva to lubricate your mouth, wash away food, and neutralize the acids produced by plaque, extensive cavities can form.

Your dentist can recommend various methods to restore moisture. For example, sugar-free candy or gum stimulates saliva flow, and moisture can be replaced by using artificial saliva and oral rinses.

Another issue that can affect older adults is a loss of appetite due to a change in your sense of taste. Besides an age-related decrease in the sense of taste and smell, certain diseases, medications and dentures can contribute to a decrease in your sense of taste.

Whether you are suffering from dry mouth or problems with your sense of taste, your dentist will be able to make suggestions to help.

The secrets of brushing and flossing your teeth effectively

Though many of us say we brush our teeth regularly, you get the best results by making sure you brush properly.

Here are the steps you should follow:

First, place the toothbrush at a 45-degree angle to your gums.

Then, move the brush back and forth gently in short (tooth-wide) strokes.

Brush the outer tooth surfaces, the inner tooth surfaces, and the chewing surfaces of the teeth.

Use the “toe” of the brush to clean the inside surfaces of the front teeth, using a gentle up-and-down stroke.

Finally, brush your tongue to remove bacteria and freshen your breath.

As well as brushing your teeth, you should floss them every day. Heres how to floss for best results.

Break off about 18 inches of floss and wind most of it around one of your middle fingers.

Then wind the remaining floss around the same finger on the opposite hand. This finger will take up the floss as it becomes dirty.

Hold the floss tightly between your thumbs and forefingers.

Guide the floss between your teeth using a gentle rubbing motion. Never snap the floss into the gums.

When the floss reaches the gum line, curve it into a C shape against one tooth. Gently slide it into the space between the gum and the tooth.

Hold the floss tightly against the tooth. Gently rub the side of the tooth, moving the floss away from the gum with up and down motions.

Repeat this method on the rest of your teeth.

Don’t forget the back side of your last tooth.

If you have difficulty handling dental floss, consider other types of interdental cleaner such as special brushes, picks or sticks.

Your dentist or hygienist will be able to give your further tips on how to brush and floss for best results.

Solving the problem of bad breath

Bad breath – which is also known as halitosis – is a worrying problem that can also be embarrassing.

But theres no need to put up with it. If you suffer from bad breath, your dentist will be able to suggest a range of solutions.

Your dentist will be able to spot problems such as gum disease, dry mouth or other disorders. Thats why its important to maintain good oral hygiene, schedule regular visits to the dentist and have professional cleaning.

Make sure you brush your teeth twice a day and clean between your teeth each day using floss or interdental cleaners. Don’t forget to brush your tongue, too!

If your dental check up shows that your mouth is healthy, your dentist may refer you to your family physician as sometimes bad breath can be a sign of other health problems.

If the odor is due to periodontal (gum) disease, sometimes professional periodontal cleaning is needed to remove the bacteria and plaque that accumulate. And your dentist may recommend a special antimicrobial mouth rinse.

Keeping your mouth healthy and stopping periodontal disease are essential to reducing bad breath.

So make sure you schedule regular dental visits for a professional cleaning and checkup.

What is plaque and how does it affect your teeth?

Plaque is a sticky film of bacteria that covers our teeth and, when we eat something, these bacteria release acids that attack the tooth enamel.

When these attacks are repeated over time, the enamel will break down and this will eventually lead to cavities.

When plaque is not removed through daily brushing and cleaning it hardens into calculus or tartar. When tartar collects above the gum line, brushing and cleaning between the teeth becomes more difficult.

The gum tissue can become swollen or may bleed. This is called gingivitis and it is the early stage of periodontal (gum) disease.

There are several steps you can take to protect yourself against this happening:

– Brush your teeth twice a day with fluoride toothpaste
– Clean between teeth daily with floss or an interdental cleaner
– Eat a balanced diet and limit the number of snacks between meals
– Visit your dentist regularly for professional cleanings and oral exams
– Ask your dentist about sealants these are protective coatings that can be applied to the back teeth where decay often starts.

If you take steps to remove the plaque each day, you have a greater chance of avoiding tooth and gum problems.

Making your teeth look better with veneers

Everybody wants the best smile possible and there’s no need to have it spoiled by gaps in your teeth or by teeth that are stained or badly shaped.

Whether the problem was caused by nature or by an injury, you may be able to have a veneer placed on top of your teeth to restore or improve your smile.

Veneers are thin, custom-made shells crafted from tooth-colored materials designed to cover the front side of teeth.

Your dentist will usually make a model of your teeth and the veneers will be made by a specialist dental technician.

A small amount of enamel has to be removed from your teeth to accommodate the shell so having veneers is usually an irreversible process.

In order to make the most of your veneer, your dentist may suggest that you avoid foods and drinks that could discolor them, such as coffee, tea or red wine.

It’s also possible that veneers might chip or fracture.

But, for many people, veneers are well worth it as they give them a completely new smile.

Root canal treatment

Root canal therapy is an important treatment that can save a tooth with a diseased nerve and which in the past would probably have needed to be removed.

Inside each tooth is the ‘pulp’ which runs like a thread down through the root and provides nutrients and nerves to the tooth. It is the soft tissue that contains nerves, blood vessels and connective tissue.

If the pulp is diseased or injured, the pulp tissue dies.

The most common cause of pulp death is a cracked tooth or a deep cavity. Both of these problems can let bacteria enter the pulp.

So, if you don’t remove it, your tooth gets infected and you could lose it.

After the dentist – or endodontist (a dentist who specializes in problems of the pulp) – removes the pulp, the root canal is cleaned and sealed off to protect it. Then your dentist places a crown over the tooth to help make it stronger.

Most of the time, a root canal is a relatively simple procedure involving one to three visits with little or no discomfort.

Your restored tooth could last a lifetime, if you continue to care for your teeth and gums and enjoy regular checkups.

How mouth protectors can save your teeth

If you take part in sports that carry a significant risk of injury, you should wear a mouth protector.

Accidents can happen during any physical activity and, if you participate in sports such as football, hockey, basketball, baseball, gymnastics and volleyball, you might be grateful for the extra protection one day.

Something as simple as a misdirected elbow in a game, or a spill off a bicycle, can leave you with chipped or broken teeth, nerve damage to a tooth or even tooth loss.

Mouth protectors usually cover the upper teeth and they can cushion the effect of a blow to the face, reducing the risk of broken teeth and injuries to the soft tissues of the mouth.

In addition, if you wear dental appliances such as braces on your lower jaw, your dentist may suggest a mouth protector for these teeth as well.

A properly fitted mouth protector will stay in place while you are wearing it, making it easy for you to talk and breathe. The three main types of mouth protectors are:

Stock: These are inexpensive and come ready to wear. But they often don't fit very well and they can be bulky making breathing and talking difficult.

Boil and bite: These can also be bought at many sport stores and may fit better than stock mouth protectors. You first soften them in water, then insert them and allow them to adapt to the shape of your mouth.

Custom-fitted: Protectors that are specially made for you by your dentist are more expensive but are likely to fit better than one you buy off the shelf.

Choosing to wear the right mouth protector can help you avoid serious long-term damage to your teeth and mouth.
