Prevention of the most common oral disease in pets consists of frequent removal of the dental plaque and tartar that forms on teeth that are not kept clean. Regularly brushing your pet’s teeth is the single most effective thing you can do to keep their teeth healthy between dental cleanings, and may reduce the frequency or even eliminate the need for periodic dental cleaning by your veterinarian. Daily brushing is best, but it’s not always possible and brushing several times a week can be effective. Most dogs accept brushing, but cats can be a bit more resistant – patience and training are important. There are many pet products marketed with claims that they improve dental health, but not all of them are effective. Talk with your veterinarian about any dental products, treats, or dental-specific diets you’re considering for your pet, or ask your veterinarian for their recommendation.https://www.avma.org/public/PetCare/Pages/Pet-Dental-Care.aspx
What about “anesthesia-free” dental cleanings? The American Veterinary Dental College does not recommend dental cleanings without anesthesia because they do not allow cleaning or inspection below the gum-line, where most dental disease occurs, and can result in injury to the pet or the person performing the procedure.
