How often should I clean my dog’s teeth?

Ideally daily, or at least 3-4 times a week. Plaque starts to mineralise into tartar within 24-48 hours, so high frequency is the key to prevention.

Can I use human toothpaste on my dog?

No. Human toothpaste contains xylitol or fluoride, both toxic to dogs. Always use a dog-specific toothpaste — they’re edible and come in palatable flavours like chicken or beef.

How much is a dental clean at the vet in the UK?

A scale and polish under general anaesthetic typically costs £250-500 depending on the practice and complexity. Extractions push the price up. Daily home brushing can stretch the gap between professional cleans from yearly to every 2-3 years.

Dog dental care: how to clean your dog’s teeth and prevent disease

Why dental health matters

Periodontal disease isn’t just bad breath. The bacteria that build up in the gums can enter the bloodstream and affect the heart, kidneys and liver. In small breeds (especially prone to tartar), untreated periodontitis can shorten life expectancy by years.

80% of dogs over three years old have some degree of periodontal disease — and most owners have no idea, because dogs don’t complain until things are bad.

Signs of dental trouble

Persistent bad breath (beyond normal "doggy" breath)
Red, swollen or bleeding gums
Difficulty eating or chewing on one side
Visible tartar (yellow-brown deposits at the gum line)
Loose or missing teeth
Pawing at the mouth

Brushing your dog’s teeth — step by step

Brushing is the single most effective home prevention. The trick is gradual conditioning:

Week 1: let the dog sniff and lick the brush and dog toothpaste. No actual brushing yet.
Week 2: with a finger brush or rubber dental thimble, gently rub the front teeth.
Week 3: introduce the brush with gentle circular movements, front teeth only.
Week 4+: extend to the whole mouth, especially the back molars (where tartar builds up fastest).

Brushing should never be a struggle. If the dog gets too stressed, go back a step. Calm persistence beats forcing.

Alternatives to brushing

If your dog will not tolerate the brush, these alternatives help (though they’re less effective):

Dental gels and sprays — applied to teeth and gums; reduce plaque without a brush.
Dental chews — look for the VOHC (Veterinary Oral Health Council) seal; those have proven efficacy. Examples in the UK: Whimzees, Pedigree Dentastix.
Hard rubber or latex toys — mechanical chewing reduces plaque on back teeth.
Kibble vs wet food — kibble has mild abrasive action; wet food encourages more plaque accumulation.

Professional veterinary cleaning: when and why

Even with home prevention, most dogs need a vet scale and polish every 1-3 years. It’s done under general anaesthetic — essential to clean the full mouth and assess every tooth properly.

Anaesthesia worries are understandable, but in healthy dogs risks are very low. The risk of leaving advanced periodontal disease untreated is far greater. So-called "anaesthesia-free dental cleaning" cleans only the visible parts of the crown, leaves the gum-line untouched, and is not recommended by the BVA or BSAVA.

Breeds most prone to dental problems

Small breeds have the same number of teeth as big dogs crammed into a smaller jaw, which causes crowding and rapid tartar build-up:

Yorkshire Terrier, Maltese, Chihuahua, Pomeranian — particularly prone
Dachshund, Bichon Frise, Cavalier King Charles Spaniel
Brachycephalic breeds in general (Pug, French Bulldog) — short jaw, crowded teeth

If you own a small breed, daily brushing is not optional: it’s preventive medicine.
