Tooth sensitivity is an uncomfortable — but not uncommon — condition many people experience. This severe sensation often occurs when dentin and tooth roots are exposed to extreme temperatures and certain substances, like salty or acidic foods. Although you should bring up the pain with your dentist during your next teeth cleaning, knowing more about the causes of tooth sensitivity will leave you in a position to take better care of your pearly whites and eliminate discomfort in the meantime. 

3 Causes of Tooth Sensitivity 

1. Teeth Are Damaged

Enamel is like a coat of armor for your teeth, protecting the dentin layer underneath. Tiny tubules are inside this tissue. When dentin is exposed, the tubules let heat, cold, and aggravating substances reach nerves, causing a painful reaction. Brushing too hard with a stiff toothbrush, eating too many acidic foods, and grinding your teeth can wear away the enamel. Cavities can also expose dentin, so if your dentist notices one during a regular teeth cleaning, they’ll schedule an appointment to give you a filling and repair the damage. 

2. Gums Are Receding

Hard brushing can also cause the gum line to recede, exposing the dentin layer. Without regular flossing, food and beverage residue can also collect on the gum line, leading to gingivitis. When the gums are inflamed, tooth roots can become visible and cause pain and discomfort when eating and drinking. If gingivitis is left untreated, it can turn into periodontal disease. Severe damage to gum tissue can leave dentin and roots without protection. 

3. Dental Care Products Have Caused Damage

Some over-the-counter dental care products can do more harm than good. Many at-home teeth whitening treatments, for example, contain strong chemicals that can cause premature wear to enamel. Similarly, acids in mouthwash can also strip away the hard, protective layer. Look for products with the ADA Seal of Acceptance, and always approve any whitening methods with your dentist.
