If you scream -- for pain, not pleasure -- when you have ice cream, you’re not alone: Forty million adults in the U.S. have sensitive teeth.
Pain is triggered by highly sensitive nerves that reside deep inside a tooth. In healthy teeth, these nerves are shielded by a porous tissue called dentin, which is protected by your gums and by a tough outer layer of enamel.
When microscopic holes in the dentin, called, tubules, are exposed, however, food, drinks, heat or cold can irritate the nerves and cause pain.
Sensitive teeth hurt, but you’re not doomed to never eat another fudgesicle again. Here are the best ways to find relief.
1. Use toothpaste formulated for sensitive
teeth.
Several ingredients,
including fluoride and potassium nitrate, have been shown to reduce
sensitivity by blocking pain signals transmitted from the nerves to the
brain. Another ingredient to look for is stabilized stannous fluoride.
It works differently, preventing sensitivity by blocking dentinal
tubules. Follow directions for use on the packaging and don’t
give up -- it may take up to two weeks to work.
2. Lighten
up.
While it may seem
counterintuitive, brushing harder is worse for your teeth, not better.
Always brush gently, using a soft-bristled brush, to avoid injuring your
gums and exposing tooth roots. Hint: If you recently replaced your
toothbrush and the bristles are already pushed out sideways,
you’re probably brushing too
hard.
3. Avoid acidic foods
and drinks.
Soda, citrus juices, sour
candy and even pickles contain high amounts of acid that can erode
tooth enamel. If it’s too difficult to eliminate them
entirely, swish water around in your mouth after you eat or
drink.
4. See your
dentist.
“The underlying
cause must be addressed to fully treat the problem of sensitive
teeth,” says Dr. Elisa Mello, clinical assistant professor at
New York University College of Dentistry. Tooth decay, receding gums or
tooth grinding could be a main, treatable source of your woes.
Troubleshoot with your dentist, who may suggest such in-office
treatments as extra-strong fluoride gels, sealants, surgical gum grafts,
a root canal, fillings or crowns.
