Tooth sensitivity is a painful dental condition that occurs when you consume hot or cold and acidic beverages or food. The tooth enamel protects the pulp and dentin of the tooth. The enamel tends to become thin because of repeated exposure to extreme temperatures, acidity, receding gums, fractured or chipped teeth, tooth grinding while sleeping, and many more, causing sensitivity. Your dentist will examine your teeth and recommend the right treatment to reduce sensitivity.
