Dog dental disease is one of the most common problems UK vets see, and it often goes unnoticed until a tooth is already in trouble. It begins as plaque, moves on to sore, inflamed gums, and can progress to bone loss around the teeth. Here is what UK owners need to know about the stages, the signs, and the daily support you can add at home.
Quick answer: what is dog dental disease?
Dog dental disease, also called periodontal disease, is inflammation and infection of the gums and the structures that hold the teeth in place, driven by plaque bacteria. The first stage, gingivitis, can be reversed with good plaque control. Later stages cause lasting damage and need your vet. Daily brushing, a daily dental powder and a yearly check help maintain a healthier mouth.

Every meal leaves a sticky film of bacteria on the teeth called plaque. If it is not removed, minerals in saliva harden it into tartar (calculus) within a few days. Tartar is rough, so it traps even more plaque against the gum. The bacteria and your dog’s own immune response inflame the gums, which is gingivitis. When the inflammation reaches the ligament and bone around the root, it becomes periodontitis, the true form of periodontal disease.
The PDSA, the UK’s largest veterinary charity, notes that dental disease is very common in dogs, and most of the damage sits below the gum line where you cannot see it. Dogs are also very good at hiding pain, which is why it is easy to miss.
The four stages of periodontal disease in dogs
- Stage 1, gingivitis: red, slightly swollen gums with a thin line of plaque. Reversible.
- Stage 2, early periodontitis: mild loss of attachment and small pockets. Breath is usually noticeably worse.
- Stage 3, moderate periodontitis: significant bone loss, bleeding or receding gums, and some teeth may need extracting.
- Stage 4, advanced periodontitis: severe bone loss, loose teeth, and often infection around the root, sometimes with swelling below the eye.
Signs and symptoms to watch for
- Persistent bad breath that is stronger than normal “doggy breath”
- Yellow or brown tartar, especially on the back teeth
- Red, swollen or bleeding gums
- Drooling, dropping food, or chewing on one side
- Pawing at the face, or going head-shy
- Loose or missing teeth, or a swelling on the face
Bleeding, facial swelling or a dog that refuses food should be seen promptly. The PDSA has a helpful guide on how to check your dog’s teeth.
Causes and risk factors
- Breed and size. Small breeds such as Yorkshire Terriers, Cavalier King Charles Spaniels and Chihuahuas have crowded teeth in small jaws, which trap plaque.
- Age. The longer plaque has been building up, the more likely periodontitis becomes.
- No daily care. Without any plaque control, tartar can form within days.
- Chews that are too hard. Very hard bones, antlers and some toys can fracture teeth, so choose chews with a little give.
- Genetics. Some dogs simply build tartar faster than others.
Daily plaque control is easier when it fits your dog’s routine.

Your vet will check every tooth, probe for pockets and look at the gums. A proper dental is carried out under general anaesthetic with dental X-rays, because around two thirds of each tooth is below the gum. The World Small Animal Veterinary Association (WSAVA), whose guidelines UK practices follow, says tartar removal alone is not enough without a full assessment under the gum line. Beware of “anaesthetic-free” scaling offered outside a vet practice, which cleans only what you can already see.
Safe support at home
- Brushing. A soft brush and dog-safe, xylitol-free toothpaste, 30 to 60 seconds a day.
- Daily dental powder. A powder sprinkled on food is a no-brushing option for dogs that will not tolerate a brush. See our dog dental powder guide for the UK.
- Suitable chews. If you cannot dent it with a thumbnail, it may be too hard for teeth.
- Yearly dental checks. Most UK practices include one in the annual vaccination visit.
Safety note: never use anything containing xylitol, which is highly toxic to dogs, and never use human toothpaste.
Ingredients worth knowing
Pure Majesty Pets Dog Dental Powder is formulated to support cleaner teeth and fresher breath while your dog eats. Its label lists hydroxyapatite (the mineral in enamel), sodium hexametaphosphate (a chelator used in oral care), zinc citrate for fresher breath, glucose oxidase and lactoperoxidase enzymes that support the mouth’s natural defences, kelp (Ascophyllum nodosum), and green tea extract for gum support. Research on single ingredients is not a clinical trial of the finished product, and a powder does not remove tartar that has already hardened.

When to call your vet
Book an appointment if you notice bleeding gums, a broken or loose tooth, swelling under the eye, drooling with a refusal to eat, or breath that suddenly turns foul. Dogs with diabetes or heart conditions, or those on medication, should check with their vet before starting any supplement.

Frequently asked questions
Can gum disease in dogs be reversed?
Only the very first stage. Gingivitis, where the gums are red and puffy but the tooth is still firmly attached, can settle once plaque is removed and kept off. Periodontitis means the bone and ligaments around the tooth have been damaged, and that cannot be undone. Your vet can stop it getting worse, which is why catching it early matters.
How do I know if my dog has dental disease?
Persistent bad breath, brown tartar along the gum line, red or bleeding gums, drooling, dropping food, chewing on one side, or pawing at the mouth are the usual clues. Many dogs hide pain well, so a yearly check at your vet practice is the only reliable way to find problems under the gum line.
How much does a dog dental cost in the UK?
Prices vary a lot between practices and depend on the size of your dog, how many extractions are needed, and whether dental X-rays are included. Ask your vet for a written estimate before booking, and check whether your pet insurance policy covers dental work, as many only cover accidents or dental illness.
Is dental disease painful for dogs?
It can be, although most dogs show it only in subtle ways, such as eating more slowly, going off hard food, or becoming head-shy. Plenty of owners report a livelier, happier dog once a sore mouth has been dealt with.
Can I clean my dog’s teeth without anaesthetic?
Brushing at home is ideal, and it does not need anaesthetic. A professional scale and polish is different. Scraping visible tartar from a conscious dog does not clean below the gum line and cannot find disease, so veterinary dentistry is done under general anaesthetic with X-rays.
What can I do at home to support my dog’s teeth?
Daily brushing with a dog toothpaste is the gold standard. A daily dental powder such as Pure Majesty Pets Dog Dental Powder, suitable chews, and a yearly dental check add daily wellness support. None of these removes tartar that has already hardened.
