Tooth sensitivity is a common dental problem that usually starts with a temporary sudden, sharp pain when eating, drinking or brushing your teeth and sometimes when exposed to cold air. At least 40 million adults suffer from sensitive teeth in the United States, according to the American Academy of General Dentistry.
5 Reasons for Tooth Sensitivity
1. Tooth grinding – Most people to some extent grind their teeth mainly at night and primarily when they are under stress. This grinding can wear away the enamel and leave the dentin exposed.
2. Receding gums – Brushing your teeth too vigorously or with a toothbrush that has hard bristles can wear away tooth enamel and expose dentin.
3. Chipped or fractured teeth – Broken teeth are a highway for bacteria and cause inflammation in the pulp of the tooth. More severe cases can lead to abscess and infection.
4. Acidic and sugary sweet foods – Citrus fruits and sticky sweet candy encourage enamel reduction.
5. Fillings – Sometimes after a composite filling, teeth become sensitive when biting down. This can be fixed with a simple bite adjustment.
Like anything else, you need a diagnosis. If the cause is not understood the symptoms may lessen, but they will not disappear. Proper diagnosis of the sensitivity is essential for treatment, and there is no single treatment that works for everyone.
