Feline odontoclastic resorptive lesions (FORLs) are the most commonly seen dental lesions in cats. On examination, there is a loss of dental tissue on the [[Crown - Anatomy & Physiology|crown]] or at the neck of the teeth. The crown may be completely resorbed with the remaining root covered with [[Oral Cavity - Teeth & Gingiva - Anatomy & Physiology|gingiva]].

The aetiology and pathogenesis of FORLs has not yet been demonstrated but is almost certainly multifactorial. Possible hypotheses that have been suggested include, the texture of the diet, abnormal calcium regulation, hypervitaminosis A, mechanical stress, anatomical abnormalities of the teeth, viral infections and plaque bacteria and periodontal disease.
