Worn Teeth (Abrasion vs. Attrition)

Freckles

Abrasions

Wear of a tooth from inappropriate chewing (tennis balls, stones, cages, fences, leash, biting fur due to pruritis or itching)

Treatment Options

  • If the dentin is exposed and the tooth is living: sealant and bonding is indicated.
  • If the pulp is exposed and thus the tooth is dead: extraction vs. root canal therapy is indicated depending on the tooth.

Attrition

  • Wear of a tooth from “wearing or rubbing” against other teeth
  • Physiological: normal wear due to mastication (chewing)
  • Pathological: abnormal wear due to malocclusion (abnormal alignment of teeth) or bruxism (tooth grinding)

Treatment Options

  • Correct Malocclusion (orthodontics vs. extractions) if appropriate
  • If the dentin is exposed and the tooth is living—sealant and bonding is indicated.
  • If the pulp is exposed and thus the tooth is dead—extraction vs. root canal therapy is indicated depending on the tooth.
