Tooth sensitivity is something that affects a number of people. It is often caused by eating or drinking something hot, cold, sweet or acidic.
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 pain usually subsides after a short period of time.
While tooth sensitivity is one of the most common dental problems, not everyone requires the same treatment. Your treatment will change depending on the cause. Fortunately most all types of sensitivity are treatable, sometimes right from your home.
Tooth sensitivity is a common name for dentin hypersensitivity or root sensitivity. If hot, cold, sweet or very acidic foods and drinks, or breathing in cold air, makes your teeth or a tooth sensitive or painful then you have sensitive teeth.
