Tooth sensitivity is the condition of a short, sharp pain experienced on consumption of hot or cold food or/and beverages. The outermost layer of our teeth is enamel, covering the crown of tooth, the cementum covers the root of the tooth and dentine is the inner layer. Tooth sensitivity is caused when the tooth enamel is worn away and the dentine is exposed. There are several ways in which tooth enamel can be worn away, thereby exposing the dentine, leaving the teeth prone to sensitivity.
Consuming acidic foods and drinks
When exposed dentine comes into contact with anything hot, cold, sweet, or sour, it can trigger the nerves and cause a short sharp pain. Even breathing in cold air can trigger pain in sensitive teeth.
