Tooth sensitivity is due to the exposure of dentin, the part of the tooth which covers the nerve, either through loss of the enamel layer or recession of the gums. Temperature changes and certain foods (acidic or sweet) can cause the tooth or teeth to be painful.
The best way to find out why a tooth is sensitive is to have our office examine you. We can look for the signs of dentin exposure, and run tests to determine what the true cause of the sensitivity is. Sometimes, the sensitivity is due to a cavity or gum disease – these can be treated to address the sensitivity. Other times, the cause of the sensitivity is because the enamel has been lost through abrasion or erosion, or the gums have receded, causing the roots to be exposed.
There are a number of treatments available, and we can help you find those that will work best, depending on your situation.
