ABRASION

Definition :

Abrasion is a type of dental wear that is caused by the mechanical removal of tooth structure by another tooth. Abrasion can also be caused by toothbrush bristles that are too hard or by using a toothbrush with incorrect technique.  

Different Types of Abrasion:

1. Extrinsic Abrasion:

This is caused by contact between two teeth with opposing occlusal surfaces.

2. Intrinsic Abrasion:

This is caused by contact between a tooth and something else inside the mouth, such as the tongue or cheek.

3. Brush Abrasion:

This is caused by toothbrush bristles that are too hard or by using a toothbrush with incorrect technique.

4. Buccal Surface Abrasion:

This is found on the buccal surfaces of teeth (the surfaces that face the cheek).

5. Occlusal Surface Abrasion:

This is found on the occlusal surfaces (the biting surfaces).

Causes for Abrasion:

  • Brushing teeth too hard
  • Using a toothbrush with bristles that are too stiff
  • Incorrect tooth brushing technique
  • Chewing on hard objects
  • Clenching or grinding teeth (bruxism)
  • Eating acidic foods and drinks

Symptoms :

  • Visible loss of tooth structure
  • Teeth may appear shorter
  • Sensitive teeth
  • Roughness on the tooth surface
  • Discoloration of the teeth

Preventive Methods:

  • Use a soft-bristled toothbrush
  • Use the correct tooth brushing technique
  • Avoid chewing on hard objects
  • Wear a mouth guard at night if you grind your teeth (bruxism)
  • Eat a balanced diet and avoid acidic foods and drinks
  • See your dentist regularly for checkups and cleanings.

Conclusion :

Abrasion can cause a loss of tooth structure and can lead to dental wear, cavities, and even tooth loss. It is important to maintain good oral hygiene and use a soft-bristled toothbrush to avoid abrasion.
