Tooth sensitivity is a relatively common problem and can range from mild discomfort to sharp, sudden, shooting pain. It is triggered by a range of factors including eating or drinking something hot or cold, sweet or sour or it can be as simple as just breathing in cold air.
Causes of sensitive teeth
In healthy teeth, a layer of enamel protects the crowns of your teeth- the part above the gum line. Under the gum line a layer called cementum protects the root of the tooth. Tooth sensitivity occurs when the tooth enamel or the cementum is compromised and the dentine is exposed.
