Dog Teeth Cleaning: What Happens and Why Vets Use Anaesthesia
Quick answer
The American Animal Hospital Association says most dogs and cats have some periodontal disease by three years of age, often unnoticed by owners. US veterinary bodies say a professional cleaning should be done under general anaesthesia: AAHA calls cleaning without it unacceptable and below the standard of care, because the teeth below the gumline cannot be reached or fully examined in an awake animal.

Why it matters
AAHA says that by three years of age most dogs and cats have some level of periodontal disease, that it often goes unnoticed, and that it can be prevented with regular dental examinations and proper home care. Its 2019 guidelines set out a 12-step protocol for the oral assessment, cleaning and treatment. Source: AAHA, 2019 Dental Care Guidelines for Dogs and Cats.
Why vets use general anaesthesia
The American Veterinary Dental College's position, reported by the AVMA, is that scaling without anaesthesia is inappropriate: even slight head movement can injure the mouth, the area below the gumline cannot be reached in an awake dog or cat, and a complete oral examination is not possible. Anaesthesia with a breathing tube gives cooperation, pain control and protects the airway. AAHA guidelines call cleaning without general anaesthesia unacceptable and below the standard of care, and the AVMA's policy says probing, dental X-rays, scaling and extractions should be done under anaesthesia when an exam justifies them.

What the visit usually involves
Under anaesthesia the vet can examine every tooth, probe the gums, take dental X-rays to see below the gumline, clean above and below it, and treat what they find. A vet quoted by the AVMA notes that dogs and cats need to be asleep for dental X-rays, and that an awake cleaning leaves parts of the mouth unexamined that may still be diseased.

What to ask before you book
- A written estimate that separates the anaesthetic, X-rays, cleaning and any extractions, and how the practice will contact you if more treatment is needed once your dog is asleep.
- Whether pre-anaesthetic blood tests are recommended for your dog.
- How pain will be managed afterwards.
- What home care your vet recommends to keep the teeth clean between visits: dog dental care at home.
Prices vary widely by clinic and by what is found, which is why the estimate matters: vet costs guide.
