Sensitive Teeth Treatment

Tooth sensitivity, medically known as dentin hypersensitivity, is a common dental condition that causes discomfort or sharp pain when teeth are exposed to certain stimuli such as cold, hot, sweet, acidic foods or drinks, or even when brushing and flossing.

Common Causes Include:

Aggressive Brushing: Brushing your teeth too hard or using a hard-bristled toothbrush can wear down enamel and push gums back.
Gum Recession: Often caused by gum disease, exposing the root surface which isn’t protected by enamel.
Tooth Decay: Cavities or damaged fillings can expose dentin.
Acidic Foods and Beverages: Excessive consumption of citrus fruits, soda, wine, and vinegar-based products erodes enamel.
Teeth Grinding (Bruxism): Can wear down enamel and lead to sensitivity.
Teeth Whitening Products: Some over-the-counter whitening products can cause temporary sensitivity.
Post-Dental Procedure Sensitivity: Procedures like fillings, crowns, or teeth cleaning can lead to short-term sensitivity.
Cracked or Chipped Teeth: These can expose the tooth nerve.

Treatment Options for Sensitive Teeth

Depending on the severity and cause, treatment for sensitive teeth can range from at-home remedies to professional dental procedures.

Desensitizing Toothpaste

One of the first treatments usually recommended. These contain compounds like:

Potassium nitrate: Helps block pain signals from nerve to brain
Strontium chloride: Blocks tubules in the dentin

It may take several weeks of regular use for noticeable relief.

Fluoride Treatment

Dentists may apply topical fluoride gel or varnish to strengthen enamel and reduce pain. Prescription-strength fluoride toothpaste may also be recommended.

Bonding Agents

If exposed dentin or root surfaces are causing sensitivity, a dentist may apply bonding resin to cover these areas and block stimuli.

Gum Grafting

In cases where gum recession has exposed root surfaces, a surgical gum graft may be used to cover exposed roots and reduce sensitivity.

Root Canal Treatment

For severe, persistent sensitivity that doesn’t respond to other treatments, root canal therapy may be necessary. This procedure removes the infected or irritated pulp and eliminates sensitivity.

Dental Sealants

Sealants can be applied to protect sensitive areas from exposure to external stimuli.

Mouthguard for Bruxism

If grinding is the root cause, a custom-fitted mouthguard can help protect enamel during sleep.
