Sensitive Teeth Causes and Treatment — Stop Tooth Sensitivity

Tooth sensitivity is a common problem that affects millions of people worldwide. It causes a sharp, sudden pain when teeth are exposed to hot, cold, sweet, or acidic foods and drinks. Sensitivity usually happens when the protective enamel is worn down or gums recede, exposing the dentin underneath. Dentin contains microscopic tubules that connect to the tooth nerve, which is why temperature changes cause pain. Studies estimate that 1 in 8 adults experiences some form of tooth sensitivity.

Many patients in Bhubaneswar experience tooth sensitivity but ignore it until it becomes severe. The habit of consuming very hot beverages, acidic foods, and sugary drinks is common in Odisha, contributing to enamel erosion. Early treatment can prevent the problem from worsening and save you from needing more complex procedures like root canals or gum surgery.

At YourDentist Laser Dental Clinic in Bhubaneswar, Dr. Arpita Dash treats tooth sensitivity by finding the root cause and providing targeted treatment.

What causes tooth sensitivity?

Enamel erosion

Acids from food, drinks, and stomach acid can wear away enamel. Citrus fruits, soft drinks, and frequent vomiting can contribute.

Gum recession

When gums recede, the root surface becomes exposed. The root surface is softer than enamel and more sensitive.

Tooth decay

Cavities expose the inner layers of the tooth, causing sensitivity.

Cracked or chipped teeth

Cracks allow stimuli to reach the nerve, causing pain.

Grinding or clenching

Bruxism wears down enamel and increases sensitivity.

Aggressive brushing

Brushing too hard with a hard-bristle brush can wear enamel and cause gum recession.

Whitening products

Some over-the-counter whitening products can cause temporary sensitivity.

Recent dental treatment

Teeth may be sensitive after fillings, scaling, or whitening. This usually improves within a few days.

How dentin hypersensitivity works

To understand sensitivity, it helps to know how teeth are structured:

1. Enamel is the hard outer layer that protects the tooth.
2. Dentin is the layer beneath enamel. It contains thousands of microscopic tubules.
3. Pulp is the innermost layer containing nerves and blood vessels.

When enamel is worn or gums recede, dentin is exposed. Temperature changes, sweet foods, and acidic drinks travel through the tubules to the nerve, causing sharp pain.

Sensitivity after dental treatment

Some sensitivity is normal after certain dental procedures:

Procedure	How long sensitivity lasts
Filling	1 to 2 weeks
Scaling and cleaning	1 to 3 days
Teeth whitening	1 to 3 days
Crown placement	1 to 2 weeks
Orthodontic adjustment	1 to 3 days

If sensitivity persists beyond these timeframes, contact YourDentist for a review.
