Periodontal Disease

Periodontal disease is inflammation and destruction of the tooth-supporting structures caused by plaque bacteria. It is the most common health problem in adult pets, affecting over 80% of dogs and 70% of cats by age three.

Key Facts

  • Plaque forms within hours of cleaning; hardens into calculus (tartar) within days
  • Four stages: gingivitis (Stage 1), early periodontitis (Stage 2), established periodontitis (Stage 3), advanced periodontitis (Stage 4)
  • Gingivitis is reversible with cleaning; periodontitis (bone loss) is not curable but is controllable
  • Small breeds and brachycephalic breeds are more prone due to tooth crowding
  • Bacteria from dental infections can spread to heart, liver, and kidneys
  • Daily tooth brushing is the single most effective prevention
  • Professional cleaning under anesthesia is essential for below-gumline treatment
  • Dental X-rays are critical; more than half of each tooth is below the gumline
  • Species: dogs and cats
