Feeling a sudden sharp pain when sipping hot tea or biting into cold desserts? That’s dental sensitivity—a common condition that affects many people in Bangalore and India. While often overlooked, it signals underlying dental issues that deserve attention. In this guide, we’ll explore what causes sensitive teeth, how they can be treated, and effective home care tips for lasting relief.

What is Dental Sensitivity?

Dental sensitivity, also known as dentin hypersensitivity, occurs when exposed dentin (the layer beneath enamel) allows external stimuli—like heat, cold, or sugars—to reach the nerves, causing sharp pain.

This exposure usually happens due to thinning enamel or receding gums.

Common Causes of Dental Sensitivity

Worn Enamel: Brushing too hard, abrasive toothpaste, or acid erosion can wear down enamel, exposing dentinal tubules.
Gum Recession: Exposed tooth roots are more vulnerable to external triggers.
Cavities, Cracks, or Fractures: These break the protective layers and expose nerves.
Post-Dental Treatments: Temporary sensitivity may occur after deep cleaning, whitening, or fillings.
Acidic Foods & Drinks: Frequent exposure to acid weakens enamel over time.

Bruxism (Teeth Grinding): Clenching or grinding wears down enamel and exposes dentin.
