What Is Teeth Abfraction?
Teeth abfraction refers to the loss of tooth structure near the gum line caused by mechanical forces such as chewing and grinding. Unlike cavities caused by decay, abfraction results from stress on the teeth leading to small notches or lesions at the base of the tooth.
Causes of Abfraction
The main causes include:
Excessive teeth grinding or clenching (bruxism)
Improper bite or misaligned teeth
Repeated flexing and stress on teeth during chewing
Aggressive tooth brushing (can contribute but is distinct from abrasion)
Chewing hard or abrasive foods
Signs and Symptoms
Small V-shaped notches near the gum line
Tooth sensitivity, especially to cold or sweet foods
Visible grooves or wear on tooth enamel
Possible gum recession around affected teeth
Discomfort when biting or chewing
How Is Abfraction Different from Abrasion and Erosion?
Abfraction is caused by mechanical stress and flexing of the tooth.
Abrasion results from physical wear, like aggressive brushing.
Erosion comes from acid damage due to diet or gastric reflux.
Often, these conditions can occur together, requiring comprehensive treatment.
Treatment Options for Teeth Abfraction
Dental Bonding or Composite Fillings: To restore the lost tooth structure and reduce sensitivity.
Night Guards: To protect teeth from grinding forces during sleep.
Bite Adjustment: Correcting misaligned bites to reduce stress on teeth.
Gentle Tooth Brushing: Using a soft-bristle brush and proper technique to avoid worsening lesions.
Desensitizing Toothpaste: To help manage sensitivity caused by abfraction.
Preventing Teeth Abfraction
Manage bruxism with stress reduction or dental devices
Avoid hard or abrasive foods
Maintain good oral hygiene with gentle brushing
Regular dental check-ups to monitor tooth wear and bite issues
