What Is Tooth Sensitivity?

Tooth sensitivity, also known as dentin hypersensitivity, is a common dental condition that causes sharp, temporary pain or discomfort when teeth are exposed to certain triggers such as cold, hot, sweet, acidic foods or even cold air.

How it occurs ?

Tooth sensitivity occurs when the protective enamel layer wears down or when gum recession exposes the underlying dentin, allowing external stimuli to reach the nerve of the tooth.

At Singh Dental Care, we identify the underlying cause of tooth sensitivity and provide personalized treatment to help you enjoy your favorite foods and drinks comfortably.

Signs and Symptoms

• Sharp pain while consuming cold foods or beverages

• Discomfort while eating hot foods or drinking hot beverages

• Sensitivity to sweet foods and drinks

• Pain when consuming acidic foods such as citrus fruits

• Discomfort while brushing or flossing

• Sensitivity to cold air/air spray

• Temporary pain that disappears once the trigger is removed

Causes of Tooth Sensitivity

• Enamel Wear :- The enamel protects the tooth surface as it is protective layer of the tooth. When it wears away due to different reasons, the underlying dentin becomes exposed.

• Gum Recession:- Receding gums due to excessive brushing force expose the root surface of the tooth, which lacks protective enamel.

• Tooth Decay (Cavities) :- Cavities can expose sensitive inner layers of the tooth, If left untreated for long time.

• Cracked or Chipped Teeth :- Damage/Fracture of the tooth structure may expose the dentin and nerves, which cause tooth sensitivity.

• Teeth Grinding (Bruxism) :- Grinding or clenching of teeth can wear down enamel over the time period.

• Aggressive Brushing :- Brushing too hard or using a hard-bristled toothbrush may damage enamel and gums as it causes wearing of enamel.

• Acidic Foods and Drinks :- Frequent consumption of acidic beverages and foods can erode enamel over the time period.

• Recent Dental Procedures :- Temporary sensitivity may occur after teeth whitening, fillings, crowns or professional cleaning, which subsides after some time.

Risk Factors

• Aggressive brushing using a hard bristled toothbrush

• Frequently consume acidic foods or soft drinks

• Gum diseases
