Tooth sensitivity is a condition when the nerve endings in the teeth are overly sensitive to hold and cold conditions. Drinking and eating hot or cold food may cause a sharp pain in the tooth. A material called dentin, which is what makes up the inside of your tooth, is protected by the enamel in the crown and the cementum in the root of the tooth. In cases when the dentin loses its covering, teeth may be become sensitive.

Causes of sensitive teeth

1. Inflammation caused by bacteria may lead to sensitive teeth.
2. Gum diseases such as gingivitis may cause the gums to retract and reveal the roots of your teeth.
3. Constantly grinding your teeth can cause the enamel to break down, which leads to exposure of the dentin.
4. Accumulation of plaque can cause sensitive teeth.
5. Various acidic foods such as lemon cause the enamel to be worn out.
6. Sensitive teeth is caused by decay of the tooth.
7. Various dental procedures such as teeth restoration and cleaning of the teeth cause the teeth to be sensitive.
