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.

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.

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 pre-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.

How braces can be made to look good

Orthodontic appliances such as braces can be used to help straighten out crooked and crowded teeth.

This is not just about looking better; it also helps improve your dental health.

How they look may determine how you feel about wearing them but, these days, braces can be as inconspicuous as you want.

Brackets the part of the braces that attaches to each tooth can sometimes be attached to the back of the tooth, making them less noticeable.

The brackets can be made in a wide range of different materials such as metal, ceramic or plastic.

They can also be designed to look appealing. For example, they may be clear or tooth-colored. There can also be shaped in a variety of ways like hearts and footballs or created in favorite colors.

You could even go for gold-plated braces or glow-in-the-dark retainers!
