Did you know that dogs and cats can get cavities in their teeth? In dogs and cats we call it tooth resorption. This condition is very common in cats, and because of dental x-rays, is being identified more in dogs.
The exact cause of these resorptive lesions is unknown. The outer surface of the tooth, called the enamel, is eroded away which exposes the sensitive part of the tooth called the dentin. Usually these lesions are visible along the gum line. However, some can be covered with inflamed gum tissue making dental x-rays an important part in detecting these lesions.
Tooth resorption is classified into four stages based on the extent of the lesion and its appearance on x-ray. Stage 1 is a small defect in the enamel. Stage 4 is complete resorption of the crown, leaving the roots exposed. Treatment of this condition depends upon the extent of the lesion but usually involves extraction of the tooth.
