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.

How scaling and planing can help clean your teeth properly

Dental plaque is a film that builds up on your teeth and, if it is not removed through good oral hygiene, it can lead to tooth decay and gum problems.

Over time it can ultimately form a hard, rough sediment known as dental tartar or calculus, which attracts further plaque buildup.

Calculus has to be removed by a trained professional such as a hygienist or dentist.

They may do this by manual tooth scaling or using an ultrasonic device.

If the buildup is light or moderate, the dentist or hygienist may use manual scaling instruments of various shapes and sizes.

If the buildup of tartar and stains is heavy, an ultrasonic cleaner may be used. This may be followed by hand scaling.

Build up of plaque can cause inflammation of the gums leading to breakdown of the connection between the teeth and the supporting structures.

Root planing is a procedure to treat gum disease by thoroughly scaling the roots of teeth to establish a smooth, calculus-free surface.

This treatment may require local anesthesia to prevent pain. Thorough periodontal scaling customarily involves several dental visits

If conditions are more advanced, surgery may be needed for complete debridement of the roots to arrest the disease process.

Some people tend to have more buildup of calculus than others and some may be more prone to periodontal inflammation or the development of tooth decay.

It’s therefore important to follow your hygienist’s advivce on how often to return for regular cleanings – even if your insurance only covers two a year.

How smoking affects your teeth

While the general effects of smoking on your health are well-known, it can also have significant effects on your oral health.

Here are some of the ways smoking can harm your oral health and hygiene:

– Oral Cancer
– Periodontal (gum) disease
– Delayed healing after a tooth extraction or other oral surgery
– Bad breath
– Stained teeth and tongue
– Diminished sense of taste and smell

Research suggests that smoking may be responsible for almost 75% of adult gum disease.

Tobacco products damage your gum tissue by affecting the attachment of bone and soft tissue to your teeth. One effect is receding gums which expose the tooth roots and increase your risk of tooth decay or to sensitivity to hot and cold in these unprotected areas.

Cigar smoking is equally a major risk and even smokeless tobacco products contain a variety of toxins associated with cancer. Smokeless tobacco can also irritate your gum tissue.

Giving up smoking will provide a significant boost to your oral health as well as giving you the chance to live longer.

How sealants can give your teeth extra protection

Sealants are made from plastic material applied to the back teeth to protect the enamel from plaque and acids.

The plastic bonds into the depressions and grooves (pits and fissures) of the chewing surfaces of the back teeth – premolars and molars.

Although thorough brushing and flossing can help remove food particles and plaque from smooth surfaces of teeth, the toothbrush bristles cannot reach all the way into the depressions and grooves to extract food and plaque.

The benefit of sealants is that they protect these vulnerable areas by “sealing out” plaque and food.

Your dentist can apply sealants quite easily and it takes only a few minutes to seal each tooth.

The teeth being sealed will first be cleaned. Then the chewing surfaces are roughened with an acid solution which makes it easier for the sealant to stick to the tooth.

The sealant is then ‘painted’ onto the tooth enamel, where it bonds directly to the tooth and hardens.

Sometimes a special curing light is used to help the sealant harden.

As long as the sealant remains intact, the tooth surface will be protected from decay.
They usually last several years before a reapplication is needed. Your dentist will check the condition of the sealants during your regular visits and reapply them when necessary.

Sealants are ideal for children because the risk of developing pit and fissure decay starts early in life. However, many adults can benefit from sealants as well.

Your dentist can tell you whether sealants would help your oral hygiene program.

How orthodontic treatment could help you

Orthodontic treatment is the process of straightening out crooked and crowded teeth, often using appliances such as braces.

Most dentists are trained to treat some minor orthodontic problems but, if they feel a patient needs specialist treatment, they will provide a referral to an orthodontist.

An orthodontist is a dentist who specializes in the diagnosis, prevention, and treatment of dental and facial irregularities.

One of the main aims of orthodontics is to straighten teeth and correct jaw alignment through braces, corrective procedures and other appliances.

Braces are the most common appliance and there are two types:

– Fixed, which are worn all the time and can only be removed by the dentist
– Removable, which the patient can take out of the mouth

Most patients wear braces for between one and three years, depending on what conditions need correcting. This is followed by a period of wearing a retainer that holds teeth in their new positions.

There may be a little discomfort during treatment but modern braces are more comfortable than ever before. They apply a constant, gentle force to move teeth and usually require fewer adjustments than older apparatus.

While braces work best when children are still growing, they can be effective at any age.

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.

Understanding your wisdom teeth

Many patients ask whether wisdom teeth are really necessary since so many people have them removed.

The fact is that wisdom teeth are a valuable asset to the mouth when they are healthy and properly positioned.

However, problems can occur that sometimes make it better to have them removed.

For example, when the jaw isn’t large enough, the wisdom teeth can become impacted – misaligned or unable to grow in properly. They may grow sideways, emerge only part way from the gum or remain trapped beneath the gum and bone.

The reasons wisdom teeth may have to be extracted include:
– The teeth have only partially erupted. This leaves an opening for bacteria which cause infection.
– There is a chance the wisdom teeth will damage adjacent teeth.
– A cyst forms which may destroy surrounding structures such as bone or tooth roots.

Ask your dentist about the health and positioning of your wisdom teeth.

Your dentist will tell you if there are any issues and will recommend any steps needed.

Taking care of your teeth and gums during pregnancy

Your oral health is an important part of your overall health, and this is never more true than during pregnancy.

Good oral health habits not only help prevent oral problems during pregnancy, they also help the health of your unborn child.

What you eat during your pregnancy affects the development of your unborn child — including teeth.

Eating a balanced diet is necessary to provide the correct amounts of nutrients to nourish both you and your child.

Your babys teeth begin to develop between the third and sixth month of pregnancy, so it is important that you receive sufficient nutrients especially calcium, protein, phosphorous, and vitamins A, C, and D.

There is a common myth that calcium is lost from the mothers teeth during pregnancy.

In fact, the calcium your baby needs is provided by your diet, not by your teeth. If your diet does not provide enough calcium, your body will provide this mineral from stores in your bones.

If you have an adequate intake of dairy products the main source of calcium or take any supplements your obstetrician recommends this will help you get the calcium you need.

To help prevent tooth decay and periodontal disease, brush your teeth thoroughly twice a day with fluoride toothpaste to remove plaque. Be sure to clean between your teeth daily with floss or interdental cleaners.

Make regular visits to your dentist during your pregnancy to ensure the best possible health for you and your baby.

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.

How dental x-rays help improve your oral health

Many diseases of the teeth and surrounding tissues cannot be seen when your dentist examines your mouth so an X-ray examination can reveal important additional information:

For example, X-rays can help show:
– Small areas of decay between the teeth or below existing fillings
– Infections in the bone
– Gum disease
– Abscesses or cysts
– Developmental abnormalities
– Some types of tumors

The way they work is that more X-rays are absorbed by the denser parts (such as teeth and bone) than by soft tissues (such as cheeks and gums). This creates an image called a radiograph.

Tooth decay, infections and signs of gum disease appear darker because of more X-ray penetration. The interpretation of these radiographs allows the dentist to safely and accurately detect hidden abnormalities.

The frequency of X-rays (radiographs) will depend on your specific health needs.

Your dentist will review your history, examine your mouth and decide whether you need radiographs and what type.

When you are a new patient, the dentist may recommend radiographs to establish how the hidden areas of your mouth currently look to help identify changes that occur later.

X-rays can help identify and treat dental problems at an early stage and so can save time, money and unnecessary discomfort.
