Dental care is an absolutely necessary component of caring for your pet. By the age of 3, it is estimated that 80% of all dogs and 70% of all cats show signs of dental disease. The best way to help prevent dental problems is to brush your pet's teeth daily. If you have any concerns about your pet's teeth, have them examined by a Veterinarian first. Never try to start brushing when your pet's mouth is already diseased or painful.
