Brushing your pet's teeth is as important as brushing your own. It is never too early to brush their teeth at home. By the age of 3 years, 80% of pets will have periodontal disease. Bacteria from periodontal disease can spread to organs and cause illness with the kidneys, liver, and heart.
Toothbrushing can prevent further buildup of plaque and tarter, but will not reverse the damage that has already been done. It is important to have your veterinarian examine your pet's mouth and determine if a dental cleaning or any extractions are needed.
Brushing your pet's teeth should be a positive bonding experience that is reinforced with praise and rewards. Teaching your pet to accept the brushing process may take weeks or even months. It is essential to be patient.
