Tooth resorption

Canine tooth resorption

Feline tooth resorption

Classification of Tooth Resorption

  • Stage 1 (TR 1): Mild dental hard tissue loss (cementum or cementum and enamel).
  • Stage 2 (TR 2): Moderate dental hard tissue loss (cementum or cementum and enamel with loss of dentin that does not extend to the pulp cavity).
  • Stage 3 (TR 3): Deep dental hard tissue loss (cementum or cementum and enamel with loss of dentin that extends to the pulp cavity), most of the tooth retains its integrity.
  • Stage 4 (TR 4): Extensive dental hard tissue loss (cementum or cementum and enamel with loss of dentin that extends to the pulp cavity), most of the tooth has lost its integrity. (TR4a) Crown and root are equally affected, (TR4b) Crown is more severely affected than the root, (TR4c) Root is more severely affected than the crown.
  • Stage 5 (TR 5): Remnants of dental hard tissue are visible only as irregular radiopacities, and gingival covering is complete.
    This classification is based on the assumption that tooth resorption is a progressive condition.

Treatment of tooth resorption is to remove the pain and any associated infection. In cats with external resorption this involves obtaining radiographs and determining whether there is ankylosis. Teeth that have a healthy periodontal liagament should be extracted completely, whereas ankylosed teeth may be reduced in height by crown amputation and covered by suturing the gingival over the remaining root. Teeth undergoing internal resorption my either be extracted or have a root canal procedure performed.
