What Are Cavities?

What Are Cavities?
"Cavities" is another way of saying tooth decay. Tooth decay is heavily
influenced by lifestyle - what we eat, how well we take care of our teeth, the
presence of fluoride in our water and toothpaste. Heredity also plays a role
in how susceptible your teeth may be to decay.
While cavities are generally more common among children, adults are also at
risk. The types of cavities include:
- Coronal cavities - the most common type occurring in both children and
adults, coronal cavities usually are located on chewing surfaces or between
the teeth.
- Root cavities - as we age, our gums recede, leaving parts of the tooth
root exposed. Since there is no enamel covering tooth roots, these exposed
areas easily decay.
- Recurrent decay - decay can form aroun existing fillings and crowns. This
is because these areas may have a tendency to accumulate plaque, which
can ultimately lead to decay.
Adults are especially at risk for cavities if they suffer from Dry mouth,
a condition due to a lack of saliva. Dry mouth may be caused by illness,
medications, radiation therapy and chemotherapy, and may be either temporary
(days to months) or permanent, depending on its cause.
Cavities are very serious. Left untreated, a cavity can destroy your tooth
and kill the delicate nerves at its center, which may result in an abscess,
an area of infection at the root tip. Once an abscess forms, it can only be
treated with a root canal, surgery or by extracting the tooth.
How Do I Know if I Have a Cavity?
Only your dentist can tell for sure whether you have a cavity. That's because
cavities develop below the tooth's surface, where you can't see them. When
you eat foods that contain carbohydrates (sugars and starches), these carbohydrates
are eaten by the bacteria in plaque, producing acids that eat into the tooth.
Over time, the tooth enamel begins to break down beneath the surface while
the surface remains intact. When enough of the sub-surface enamel is eaten
away, the surface collapses, forming a cavity.
Cavities are most likely to develop in pits on the chewing surfaces of the
back teeth, in between teeth, and near the gumline. But regardless of where
they occur, the best way to spot them and treat them before they become serious
is by visiting your dentist regularly for checkups.
How Can I Help Prevent Cavities?
- Brush at least twice a day and floss daily to remove plaque from between
teeth and below the gumline.
- Have regular dental checkups. Preventive care can help stop problems from
occurring and keep minor problems from becoming major ones.
- Eat a well-balanced diet that limits starchy or sugary foods. When you
do eat these foods, try to eat them with your meal instead of as a snack
to minimize the number of times that your teeth are exposed to acid.
- Use dental products that contain fluoride, including toothpaste.
- Make sure that your children's drinking water is fluoridated. If your
water supply does not contain fluoride, ask us for more information.
