Quick answer: Dental disease is one of the most common problems in older dogs, especially small breeds. It causes pain, tooth loss, and infection, and is linked to inflammation elsewhere in the body. Many owners delay treatment because of worries about anesthesia, but with pre-anesthetic testing and careful monitoring, most senior dogs safely undergo dental cleanings and extractions, and often act younger once the pain is gone.
Signs in older dogs
- Bad breath
- Tartar, red gums, or bleeding
- Loose or missing teeth
- Chewing on one side, dropping food, or preferring soft food
- Pawing at the mouth or rubbing the face
- Weight loss or grumpiness
Why age isn’t a reason to skip treatment
- Age isn’t a disease. Overall health matters more.
- Pre-anesthetic bloodwork, and sometimes heart evaluation, identify risks.
- Modern anesthesia uses monitoring, IV fluids, warming, and local nerve blocks.
- Untreated dental infection is painful and can worsen other health problems.
What a dental procedure includes
- Full-mouth dental X-rays
- Cleaning above and below the gumline
- Extraction of diseased teeth
- Pain relief
Home care after treatment
- Soft food for 1–2 weeks after extractions
- Pain medication as prescribed
- Start brushing once the mouth heals
What to avoid
- Human pain relievers
- Anesthesia-free cleanings
