Dog Dental Care in the UK: Everything You Need to Know
Dental disease is the most common health condition diagnosed in adult dogs in the UK — yet it is almost entirely preventable. The PDSA estimates that up to 87% of dogs over three years of age have some degree of dental disease. Poor oral health is not just a cosmetic issue: it causes pain, affects eating, and has been linked to heart and kidney disease.
Key takeaways
- Up to 87% of dogs over three have dental disease — daily toothbrushing is the single most effective way to prevent it.
- Professional dental cleaning under anaesthesia costs £150–£400 for a routine clean, rising significantly if extractions are required.
- Under the March 2026 CMA reforms, you are legally entitled to a written estimate for any dental procedure expected to cost £500 or more.
Understanding Canine Dental Disease
Dental disease in dogs follows a predictable progression. Plaque — a soft film of bacteria — accumulates on tooth surfaces daily. If not removed by brushing or other means, plaque mineralises within 3–5 days to form calculus (tartar) — a hard, brown deposit that cannot be removed by brushing and requires professional dental cleaning under anaesthesia.
Accumulated tartar causes gingivitis (inflamed, reddened gums), and if left untreated, this progresses to periodontitis — irreversible destruction of the supporting structures around the teeth, including the bone of the jaw. Advanced periodontitis leads to loose teeth, tooth loss, jaw pain, and bone loss. It is significantly more painful than most owners realise, as dogs typically continue to eat despite severe dental pain.
The bacteria associated with dental disease can also enter the bloodstream through inflamed gum tissue, potentially affecting the heart valves (endocarditis), kidneys, and liver. Regular dental care is therefore an investment in whole-body health, not just oral hygiene.
Preventive Dental Care at Home
Daily toothbrushing is the gold standard for home dental care in dogs. Studies by the RCVS-accredited veterinary dental organisations confirm that daily brushing is the most effective single intervention for preventing plaque accumulation and gingivitis. Use a toothpaste specifically formulated for dogs — human toothpastes contain fluoride and other ingredients that are harmful if swallowed.
Introducing toothbrushing should be done gradually, starting with allowing the dog to taste the toothpaste, then touching the teeth with a finger brush or soft brush, before progressing to full brushing. Most dogs accept brushing readily if introduced positively from an early age. Even once-daily brushing for 30–60 seconds makes a meaningful difference.
If your dog will not tolerate toothbrushing, alternatives with some supporting evidence include: dental chews (particularly those bearing the Veterinary Oral Health Council (VOHC) seal of approval, such as Dentastix-type products meeting the VOHC standard); dental water additives; dental diets (such as Hill's t/d); and dental wipes. These are less effective than brushing but better than nothing. Rawhide chews are not recommended due to choking and obstruction risks.
Professional Dental Cleaning: What to Expect and What It Costs
Professional dental cleaning (scale and polish) under general anaesthesia is required once tartar has built up to a level that cannot be managed at home. This is a veterinary procedure requiring general anaesthesia to be performed safely and thoroughly — anaesthesia-free dental cleaning is not recommended by the BVA or RCVS as it is not effective and can be stressful and harmful.
The procedure involves removal of tartar above and below the gumline using ultrasonic scalers, assessment of each tooth including dental X-rays (which identify disease below the gumline), extraction of any non-viable teeth, and polishing to smooth surfaces and slow future plaque adhesion. Pre-anaesthetic blood tests are recommended, particularly for older dogs.
Costs in the UK range from £150–£400 for a routine scale and polish in a dog with mild-moderate disease. If extractions are needed, costs rise by £50–£150 per tooth, and in dogs with significant dental disease, total costs can reach £500–£1,000 or more. Dental X-rays add £100–£250. Getting a written estimate before proceeding with a dental procedure is now a legal requirement under the March 2026 CMA reforms for treatments expected to cost £500 or more.
How Often Does My Dog Need a Dental Clean?
The frequency of professional dental cleaning varies widely between individual dogs. Factors include: breed (small and toy breeds such as Yorkshire Terriers, Chihuahuas, and Dachshunds accumulate tartar faster and are more prone to dental disease); home dental care routine (dogs that are brushed daily need professional cleaning far less often); and diet (wet food tends to promote more tartar than dry food, though dental diets specifically are better than standard dry food).
Most vets recommend an annual dental examination as part of the annual booster consultation or health check. Based on this assessment, they will advise on the frequency of professional cleaning — this might range from once every 6–12 months for small breeds with poor dentition, to once every 2–3 years or less in large breeds with good home care.
Early intervention is always more effective and cheaper than waiting until dental disease is advanced. If your vet recommends a dental clean, it is generally wiser — both clinically and financially — to proceed sooner rather than delaying.
Comparing Dental Treatment Costs
The cost of dental procedures varies considerably between practices — sometimes by hundreds of pounds for the same procedure. A routine dental scale and polish in the UK averages around £233 but can range from £150 to £400 depending on the practice. In areas with high property costs (such as central London), prices tend to be at the upper end of this range.
CompareMyVet at app.comparemyvet.uk helps UK dog owners find and compare vet practices by price, so you can make an informed choice about where your dog receives dental treatment. Our platform currently covers Brighton & Hove with 29 practices listed.
Under the March 2026 CMA reforms, vets are now required to provide written estimates for treatments expected to cost £500 or more. If your dog needs a dental clean, ask for a written estimate upfront so there are no unexpected surprises. And if ongoing dental medication is prescribed, ask for a written prescription to purchase it at a reduced cost from a registered pharmacy.

Common questions
Yes. Research has linked canine periodontal disease to an increased risk of heart valve disease, kidney disease, and liver disease. Bacteria from infected gum tissue can enter the bloodstream and seed infection elsewhere. Maintaining good dental hygiene is therefore genuinely important for whole-body health, not just for fresh breath.
Anaesthesia-free dental cleaning is not recommended by the RCVS, BVA, or the British Veterinary Dental Association. Without anaesthesia, subgingival (below the gumline) cleaning — where the most damaging disease occurs — cannot be performed safely. The procedure also causes unnecessary stress to the animal. Only cleaning performed under proper anaesthesia is clinically meaningful.
Bad breath (halitosis) in dogs is most commonly caused by dental disease — bacterial activity in infected gum tissue and on the tooth surface produces unpleasant-smelling compounds. However, bad breath can also indicate kidney disease (a distinctive ammonia smell), diabetes (a sweet or fruity odour), or gastrointestinal problems. If your dog's breath changes noticeably, a vet check is worthwhile.
