What Causes Tooth Sensitivity?
Tooth sensitivity happens when the inner part of your tooth gets exposed or irritated. The clinical term is dentin hypersensitivity, and it often causes a quick, sharp pain with hot, cold, sweet, or acidic foods. It can come and go, but it should not be ignored.
Common causes include:
- Worn enamel from brushing too hard or grinding
- Gum recession, which exposes the tooth root
- Tooth decay or a cavity
- Cracked or chipped teeth
- Recent dental work
What makes tooth sensitivity worse?
Certain habits and health issues can make sensitive teeth more painful. Acidic foods, teeth grinding, and gum disease can all wear down the tooth surface or expose the root. Steps that may help:
- Use a soft toothbrush and brush gently.
- Choose toothpaste made for sensitive teeth.
- Avoid very hot, cold, or acidic foods for a while.
- See a dentist if the pain keeps happening.
When should I worry about sensitive teeth?
You should call a dentist if the pain is severe, lasts a long time, or happens with swelling. Sensitivity can be a sign of a cavity, cracked tooth, or infection. Quick treatment can stop the problem from getting worse.
FAQ
Is tooth sensitivity normal? Mild sensitivity can happen sometimes, especially after cold drinks or whitening. But if it keeps happening, it may mean enamel wear, gum recession, or decay. A dentist can find the cause and suggest the right treatment.
Can sensitive teeth mean I have a cavity? Yes, a cavity can cause sensitivity, especially to sweets, cold, or pressure. But cavities are not the only cause. Gum recession, grinding, and cracked teeth can also make teeth hurt.
Will sensitive toothpaste fix it? Sensitive toothpaste can help many people by calming the nerve inside the tooth. It may take a few weeks to work. If pain stays the same or gets worse, you should get checked by a dentist.
Can brushing too hard cause sensitivity? Yes. Hard brushing can wear away enamel and push gums back, which exposes the tooth root. Using a soft brush and gentle strokes can help protect your teeth and reduce pain.
