DENTIN HYPERSENSITIVITY

This condition is due to wearing off of the enamel, making it thinner leading to exposure of the dentin

Causes

  • Gum recession due to age or improper tooth brushing
  • Acidic beverages that cause enamel erosion and dentin exposure
  • Tooth grinding
  • Chipped or fractured tooth may also expose the dentine
  • Eating disorders, e.g. bulimia nervosa and anorexia nervosa (exposure to vomitus)

Clinical features

  • Sensitivity to hot, cold, sweet or very acidic foods and drinks, and breathing in cold air

MANAGEMENT

  • Topical application of fluoride in form of toothpaste
  • In severe conditions, refer for root canal therapy
  • Professional cleaning of teeth
