Teeth Sensitivity Q & A

What is teeth sensitivity?

Teeth sensitivity is an uncomfortable pain or sensation that occurs when tooth enamel wears down, or nerve-endings in your teeth are exposed. Often, cold foods like ice cream or cold/hot drinks trigger the pain. Breathing in cold air or eating acidic, sweet or sour foods can also be unbearable.

Teeth sensitivity is very common and occurs in both adults and children. In fact, 40 million adults suffer from sensitive teeth. It’s uncomfortable and annoying, but a serious dental problem is not usually the culprit. If you’ve noticed that your teeth are sensitive, Dr. Koo recommends making an appointment so she can discover the cause and develop a treatment plan.

What causes teeth sensitivity?

Teeth are composed of three natural hard components -- enamel, dentin, and cementum -- that each serves to protect the nerve-endings and ward off issues like cavities and gum disease. Enamel is the hardest surface of your teeth and a major protector against teeth sensitivity.

The inside of teeth is known as dental pulp, and it’s filled with connective tissue, blood vessels, and nerves. Dental pulp is protected by dentin, a hard tissue underneath the enamel. Cementum protects the roots of teeth, as well as the most visible part of your tooth, the crown area. Issues with your enamel, dentin or cementum can lead to teeth sensitivity.

The origin of teeth sensitivity can usually be traced to some common conditions:


  • Broken or chipped teeth  
  • A new cavity or worn fillings
  • Teeth-grinding that wears down enamel
  • Acidic foods or drinks, which can erode teeth
  • Aggressive brushing, which can wear down enamel
  • Receding gums, which can result from natural wear and tear or a buildup of plaque and tartar

Sometimes temporary teeth sensitivity occurs after dental treatments like crowns, fillings, and tooth whitening.

Will teeth sensitivity go away on its own?

Teeth sensitivity from recent dental treatments can last between two to six weeks. However, it’s important to discuss lingering sensitivity with Dr. Koo at Dentistry In Frisco. During your exam, Dr. Koo finds out what’s going on and treats the problem accordingly, instead of waiting for a minor issue to become a major problem or a toothache.
