Sensitive Teeth
Why are my teeth sensitive?
Exposed dentin is the likely
reason. Dentin in the tissue that makes up the core of
each tooth. Dentin is covered by a protective coating
of enamel. When this enamel wears away or decays, the
dentin becomes exposed and receptive to sensations,
including pain. Dentin exposure and sensitivity also
occur when roots are exposed due to gum recession.
When does tooth sensitivity usually
occur?
You may experience tooth
sensitivity, or dentin hypersensitivity, after eating
cold or hot foods, drinking cold or hot liquids, or
breathing cold air.
What causes dentin hypersensitivity?
Causes of dentin hypersensitivity
include brushing too hard, which wears away enamel, and
gum disease. Other causes include cracked or chipped
teeth and grinding or clenching your teeth. Medical
conditions like bulimia also may lead to exposed
dentin. Your diet may play a role as well. Consumption
of acidic foods and drinks, such as citrus fruits and
carbonated beverages, can chemically dissolve enamel
over time, resulting in exposed dentin.
What can increase dentin
hypersensitivity?
Some toothpaste brands contain
abrasive ingredients that may wear away enamel.
Ingredients found in some whitening toothpastes and
bleaching treatments may increase tooth sensitivity as
well.
How do I know when it’s time to see a
dentist?
If your teeth are highly sensitive
for more than three or four days and they react to hot
and cold temperatures, it’s best to get an evaluation
from your dentist.
How does a dentist determine dentin
hypersensitivity?
A dentist can gauge the severity of
your sensitive teeth by using an air test. The dentist
sprays air across each area of your teeth to pinpoint
the exact location of sensitivity.
What can the dentist do to treat
dentin hypersensitivity?
Your dentist will examine your
teeth, look for causes of sensitivity, and make
treatment recommendations. If sensitivity is associated
with clenching and or grinding, your dentist may
recommend a mouth guard. Dentists have a variety of
treatments for dentin hypersensitivity. Products for
home use include desensitizing toothpastes and mouth
rinses. In-office procedures include application of
desensitizing agents or protective sealants.
What can I do to improve tooth
sensitivity?
Practice good oral hygiene to
maintain healthy teeth and gums. Use a soft bristled
toothbrush and avoid brushing you teeth too hard. And
watch what you eat: Avoid acidic foods and drinks.
