Dental cleaning involves a dental exam to confirm that a dental cleaning is needed is the first step. The veterinarian will review with you what procedures are likely required prior to the dental cleaning. The veterinarian may request a preanesthetic blood tests to ensure that kidney and liver function are satisfactory for anesthesia, as well as an evaluation of the heart and abdomen if needed.
