Dental cleanings should be done at least once every 12-6 months to maintain a health mouth. Tartar is harmful to the teeth and gums in two ways… First, it serves as a place where bacteria can grow and multiply in the mouth that can lead to gum inflammation, or gingivitis. Second, as tartar builds up along the gum line, it pushes the gums away from the roots of the teeth causing sensitivity and pain. Lastly, overlooking your pets dental health could lead to heart disease, liver and kidney complications in the future. Check your pets teeth and schedule a dental appointment at the first sign of tartar build up!
