The Top 5 Causes Of Tooth Sensitivity

Is that sudden sharp twinge in your tooth familiar? You are not alone! Did you know that it’s estimated that 1 out of every 8 people experiences tooth sensitivity? While your dentist can help you determine the cause of your sensitivity, there are steps you can take and things to be aware of that can help minimize the zinging feeling you have in your teeth. Here are some key offenders when it comes to causing sensitive teeth.

Tooth Decay

If your tooth is compromised by decay, it can cause sensitivity. Being proactive about having your dentist remove the decay and restore your tooth with a dental filling is important to keep it from progressing into your nerve where it can cause an infection.


A diet high in acidic foods or beverages can wear away tooth enamel and lead to sensitivity. Some foods and drinks to be aware of are:

  • Coffee, tea, and red wine
  • Tomatoes and marinara sauce
  • Citrus fruits and juices
  • Colas, energy, and sports drinks

Brushing Vigorously

Brushing too hard daily with a hard bristle brush can result in injury to your gums and even enamel erosion in severe cases. Choose a soft bristle or electric toothbrush, and be sure to brush your teeth gently in a circular motion to avoid damage.

Teeth Whitening

Sensitivity can be a side effect of whitening your teeth. It’s best to consult your dentist if you’re experiencing any issues during whitening. Many professional whitening products have ingredients designed to minimize sensitivity. Your dentist may also recommend a fluoride rinse or toothpaste you can use after whitening.


Stress or anxiety may lead to bruxism, or clenching and grinding your teeth. This typically happens at night, so it may be difficult to diagnose. Bruxism can also cause other damage such as excessive wear to your teeth. Your dentist may recommend wearing a night guard to protect your teeth from the damage that bruxism can cause.

Did any of these sound familiar? If you are having trouble managing yours, contact your dentist to schedule an examination so you can get to the root of the problem.
