Pet Dental Care Guide
Good dental care helps protect your dog or cat from pain, tooth loss, and progressive periodontal disease. This guide explains daily home care, common warning signs, professional cleanings, and when it is time to call your veterinarian.
Why pet dental care matters
Dental disease is one of the most common health problems seen in dogs and cats. Veterinary sources note that most dogs and cats have some evidence of periodontal disease by about 3 years of age, often starting with plaque buildup and gingivitis before progressing to deeper infection, gum recession, bone loss, loose teeth, and chronic pain. Daily toothbrushing is the most effective home-care step for reducing plaque, but brushing does not remove hardened tartar once it forms. That is why at-home care and regular veterinary exams work best together. If your pet already has bad breath, visible tartar, red gums, drooling, or pain when eating, schedule an oral exam rather than assuming it is normal aging. You may also want to review related pages on /symptoms/bad-breath-in-pets, /symptoms/drooling-in-pets, /symptoms/decreased-appetite, /conditions/periodontal-disease-in-dogs, /conditions/periodontal-disease-in-cats, /conditions/gingivitis-in-dogs, and /conditions/gingivitis-in-cats.
What causes dental disease in pets
The usual starting point is plaque, a bacterial biofilm that forms on the teeth. If plaque is not removed, it can mineralize into calculus or tartar, especially near the gumline. Bacteria and the pet’s inflammatory response then damage the gums, periodontal ligaments, and bone around the teeth. Age, breed or skull shape, crowded teeth, retained baby teeth, diet, home-care routine, and existing oral abnormalities can all play a role. In cats, tooth resorption is also a major dental problem, and the exact cause remains unknown. Pets with other mouth problems may have overlapping issues, so consider related reading on /conditions/tooth-resorption-in-cats, /conditions/stomatitis-in-cats, /conditions/retained-baby-teeth-in-dogs, /conditions/broken-tooth-in-dogs, /conditions/broken-tooth-in-cats, /symptoms/bleeding-from-mouth, and /symptoms/oral-pain-in-pets.
Common signs of dental trouble at home
Bad breath
Persistent foul breath is a common early sign of periodontal disease.
Red or bleeding gums
Gingivitis often causes redness, swelling, and bleeding on contact.
Visible tartar
Yellow-brown buildup along the gumline suggests plaque has hardened.
Drooling or pawing at the mouth
These can be signs of oral pain, inflammation, or a damaged tooth.
Trouble eating
Pets may chew on one side, drop food, hesitate at meals, or stop eating.
Loose or missing teeth
Advanced disease can damage the structures that hold teeth in place.
How to brush your pet’s teeth safely
Use a pet toothbrush or finger brush and a toothpaste formulated for dogs or cats. Do not use human toothpaste. Start slowly by letting your pet taste the paste, then touch the lips and outer tooth surfaces for a few seconds at a time. Veterinary references note that brushing the outer surfaces is most important because plaque and tartar accumulate rapidly there. Aim for daily brushing, but if your pet cannot tolerate that, ask your veterinarian about alternatives such as gauze wiping, dental diets, or other Veterinary Oral Health Council accepted products. Training works best when sessions are short, calm, and rewarded. For pets that resist handling, review /guides/how-to-brush-your-dogs-teeth, /guides/how-to-brush-your-cats-teeth, /symptoms/chewing-problems-in-dogs, /symptoms/chewing-problems-in-cats, and /guides/puppy-care-guide or /guides/kitten-care-guide for early habit-building.
| Feature | Option | Best use | What it helps with | Limits |
|---|---|---|---|---|
| Daily toothbrushing | First-line home care | Removes plaque before it hardens | Requires training and consistency; does not replace a veterinary exam | |
| VOHC-accepted dental diets or treats | Adjunct home care | Can help reduce plaque or tartar accumulation | Do not replace brushing or professional treatment | |
| Dental wipes or gauze | For pets that resist a brush | Can reduce plaque on accessible outer surfaces | Usually less effective than brushing | |
| Professional veterinary dental cleaning | Diagnosis and treatment | Removes tartar above and below the gumline; allows probing and dental X-rays under anesthesia | Not a substitute for home maintenance after the procedure |
When your pet needs a professional dental cleaning
Once tartar has formed, it generally needs professional scaling and polishing. Veterinary dental cleaning is also how clinicians evaluate what is happening below the gumline, where painful disease can be hidden. Merck and AAHA note that diagnosis and treatment of periodontal disease involve general anesthesia, periodontal probing, and dental radiography. This is important because a mouth can look better after cosmetic tartar removal while disease continues underneath. During a dental procedure, your veterinarian may clean, polish, probe, take dental X-rays, treat periodontal pockets, or recommend extraction of painful, unsalvageable teeth. Pets can do very well after necessary extractions.

When to call a vet
Go to the ER now
- ● Your pet cannot eat or drink because of mouth pain.
- ● There is major facial swelling, heavy oral bleeding, or suspected jaw trauma.
- ● A tooth injury is paired with severe pain, collapse, or breathing trouble.
- ● Your pet is pawing frantically at the mouth after chewing something hard and seems in acute distress.
See a vet within 24 hours
- ● Bad breath is paired with red gums, drooling, pawing at the mouth, or reluctance to eat.
- ● You see a broken tooth, loose tooth, pus, gum recession, or a growth in the mouth.
- ● Your cat suddenly stops eating, especially if you suspect tooth resorption or stomatitis.
- ● Your dog or cat cries when chewing, drops food, or only eats softened food.
Watch at home, call if it worsens
- ● Mild plaque is present but your pet is eating normally and seems comfortable.
- ● You are starting a brushing routine and need help choosing safe products.
- ● Your pet tolerates home care but has not had an oral exam recently.
Special dental concerns in cats
Cats can develop routine plaque and periodontal disease, but they are also well known for tooth resorption and, less commonly, severe inflammatory conditions such as stomatitis. Cornell notes that tooth resorption is a common cause of tooth loss in cats and can be very painful, leading to drooling, irritability, head turning while eating, and reduced appetite. Some lesions are only found with dental X-rays under anesthesia. If your cat has persistent bad breath, chattering while eating, food avoidance, or visible gum inflammation, call your veterinarian.

Special dental concerns in dogs
Dogs commonly develop plaque, tartar, gingivitis, and progressive periodontal disease, and certain dogs may be more prone because of size, crowding, retained baby teeth, or chewing habits. Small-breed dogs often need especially consistent home care and regular oral exams. Dogs may also fracture teeth on hard chew items, leading to pain or infection that is easy to miss because many pets keep eating despite discomfort. If your dog has foul breath, one-sided chewing, face rubbing, bleeding gums, or a brown crust along the gumline, book a veterinary dental exam.

Simple dental care checklist for pet owners
Check the mouth regularly
Look for redness, tartar, broken teeth, swelling, or changes in breath.
Brush daily if possible
Daily brushing is the best-supported way to remove plaque at home.
Use pet-safe products only
Choose dog- or cat-specific toothpaste and veterinarian-recommended tools.
Ask about VOHC options
VOHC-accepted products can be useful additions to a home routine.
Schedule routine exams
Regular oral checks help catch painful disease before it becomes advanced.
Call your vet if eating changes
Dental pain often shows up as subtle changes in chewing or appetite.
