Equally important to annual dental exams at your veterinarian’s practice is home dental care, including brushing your pet’s teeth every day if possible. AAHA recommends a technique for both younger and older animals, although it’s easier to start brushing when your pet is young.
To introduce a fearful Fido or timid Tabby to the idea of dental care, start slowly and gradually. Dip a finger into beef bouillon (for dogs) or tuna water (for cats) and gently rub along your pet’s gums and teeth. The most important area to focus on is the gum line (the crevice where the gums meet the teeth), where bacteria and food mix to form plaque. Focusing on the gum line, start at the front of the mouth, then move to the back upper and lower teeth and gum areas. Once your pet is okay with a little bit of touching, gradually introduce gauze over your finger and rub the teeth and gums in a circular fashion.
