Common Causes of Tooth Sensitivity and How to Treat It

Tooth sensitivity is characterized by a sharp, temporary pain when teeth are exposed to certain stimuli like hot, cold, sweet, or acidic foods and beverages. At Express Smiles Dental Suite, we frequently treat patients with this common condition. The most common causes include: Worn tooth enamel from aggressive brushing or using a hard-bristled toothbrush; Tooth decay (cavities); Cracked or chipped teeth; Gum recession that exposes the tooth's root; Gum disease; Recent dental procedures like fillings, crowns, or teeth whitening; Grinding teeth at night (bruxism); and Acidic foods and beverages that erode enamel. To treat sensitivity, Dr. Victor Kinara recommends using desensitizing toothpaste containing compounds like potassium nitrate or strontium chloride, which block pain signals from nerve to brain. Fluoride treatments at our dental services center strengthen tooth enamel and reduce sensitivity. For severe cases, dental procedures such as bonding, crowns, inlays, or gum grafts may be necessary to address underlying issues.
