Brushing your dog's teeth every day is ideal. It will help to prevent periodontal disease that can lead to pain and dangerous infections.  If your dog has loose teeth, seems sensitive around its mouth, or is bleeding orally, consult a veterinarian before you continue brushing.  Start slowly and try to work up to daily brushing. If you are unable to brush every day, try to brush as often as possible.
