If your dog is having a dental cleaning, you should keep food and water away from them for about 12 hours before the procedure. Fast your dog the night before the dental procedure, or get specific instructions from your veterinarian. The fast is necessary to prevent your dog from vomiting while under sedation, which can lead to serious complications. At-home oral health care routines combined with dental treats can help your dog keep their teeth clean and control plaque and tartar buildup. However, the best way to keep your dog's mouth clean and healthy is to take him to the vet for an annual dental exam and hygiene cleaning. Our Windsor vets at New England Veterinary Center & Cancer Care recommend bringing your dog in for a dental appointment at least once a year, or more frequently if they are suffering from more severe or recurring dental problems, to help prevent tooth decay and periodontal disease. Start Antibiotics may also be given to dogs with severe dental infections or gingivitis a few days before the procedure to prevent complications and to try to clear the infection. Visit Your Vet for a Physical and get Bloodwork Done before the procedure to ensure your dog is healthy enough for the procedure.
