What you need to know

Dental x-rays are needed to identify any or all lesions that are present as well as direct how the root structure has been affected.

What's really going on

Tooth Resorption (TR) is a common feline dental problem. A recent study has shown an incidence of 70% in purebred cats and 40% incidence in mixed breeds. Some cats may chatter or have shift food in their mouth, however, most cats will show no symptoms at all. These lesions are painful and progressively destroy the tooth.

Careful probing of the teeth at the gingival margin with an explorer and a full mouth x-ray series (8-views) will identify these lesions and direct the treatment plan during the cat’s dental procedure. Based on the radiographic appearance of the root structure the affected tooth/teeth will receive either surgical extraction (crown & roots) or crown amputation.
