Sensitive
Teeth
If you wince with pain after sipping a hot cup
of coffee or chewing a piece of ice, chances are that you may suffer
from "dentin hypersensitivity," or more commonly known as
sensitive teeth.
Hot and cold temperature changes cause your teeth
to expand and contract. Over time, your teeth can develop microscopic
cracks that allow these sensations to seep through to the nerves. Exposed
areas of the tooth can cause pain and even affect or change your eating,
drinking, and breathing habits.
At least forty-five million adults in the United
States suffer at some time from sensitive teeth.
Abrasive toothpastes are sometimes the culprit
of sensitive teeth. Ingredients found in some whitening toothpastes
that lighten and remove stains from enamel, and sodium pyrophosphate,
the key ingredient in tartar-control toothpastes may increase tooth
sensitivity.
In some cases, a desensitizing toothpaste, sealants,
and filling materials including fluoride may alleviate some of the pain
associated with sensitive teeth.
Sometimes, a sensitive tooth may be confused by
a patient for a cavity or abscess that is not yet visible.
In any case, contact your dentist if you notice
any change in your teeth's sensitivity to temperature.
