  •  Bruxism  (Night grinding) - Clenching or severe biting of teeth during the night time. 
  • Physiological-  Age - As a person ages teeth generally wear off.
  •  Due to faulty bite - Deep bite ( if the teeth aren't arranged or aligned properly). 


  • If  you think you clench your teeth at night, and your spouse or parent complains of it, you will be given a night guard that can prevent the teeth from further wear.
  • Faulty bite - This can be discovered only by the dentist and he may suggest you to undergo bite correction ( braces).

Treatment -

  • Very mild- You can use an anti-sensitivity tooth paste like sensodyne.
  • Mild cases - If only 1-2 teeth are affected , a cement can be filled and tooth can be restored.
  • Moderate to severe cases - Root canal is done and cap is placed over the teeth to protect it from further wear.


Loss of enamel near your gum line resulting in sensitivity, is called abrasion.


  •  Wrong technique of brushing (using a hard bristle brush and brushing vigorously  in horizontal direction ), use of tooth powder,charcoal, brick powder.


  • Use  a soft bristle brush, and smooth consistency tooth paste, brush your teeth  in up and down motion.
  •  Children can brush their teeth in circular motion.

Treatment -

  • Mild  to moderate cases - A cement is placed and the tooth is restored. 
  • Severe cases- Root canal treatment.

 3. Erosion -

Erosion is a chemical damage to the tooth structure due to consumption of acidic food or due to frequent vomiting.


  • Consumption of aerated  (soft drinks), beverages,citrus fruits. 
  • Gastric trouble - repeated vomiting and acidity problems.
