Plaque forms on teeth shortly after eating and within 24 hours begins to harden, eventually turning into tartar. Tartar serves as a place for bacteria to grow, leading to gingivitis. As gingivitis worsens, periodontal disease develops, which includes inflammation, pain, and tooth loss. Prevention of plaque and tartar build-up is key. Use VOHC-accepted food and/or water additives, wipe or brush your dog’s teeth daily, and have your veterinarian perform regular dental cleanings.
