Tooth sensitivity occurs if the enamel on teeth wears down, exposing the dentin. This is very common in most of the people where the symptoms are electric sensation, tingly feeling and pain which may affect the teeth. Tooth sensitivity is caused when consuming too hot, cold, sour or acidic food and beverages and also when cold air hits the teeth. Tooth Sensitivity also results due to other factors such as gum recession, gum disease, fractured tooth,poor oral hygiene, brushing too hard which may result to loss in enamel, root nerve damage, tooth decay, teeth grinding or periodontal disease.

If a person experiences a sense of pain on drinking hot or cold liquids is caused due to death of nerve cells in the tooth. You have to visit a dentist to determine what’s the true nature of sensitivity. Tooth sensitivity results in discomfort for a person.
