Brushing is the only home measure proven to prevent plaque accumulation, and periodontal disease is the most common disease in adult dogs. The equipment is cheap; the introduction is what determines whether it happens.

Never human toothpaste
Two reasons, both serious:
Fluoride is designed to be spat out. Dogs swallow everything, and ingested fluoride in quantity causes gastrointestinal upset and, over time, other problems.
Xylitol, present in many human toothpastes, is severely toxic to dogs. It causes a catastrophic insulin release and, at higher doses, liver failure. A tiny amount can kill a small dog.
Dog toothpastes are formulated to be swallowed.
Types of dog toothpaste
Enzymatic. Contain enzyme systems that continue working after brushing by producing antibacterial compounds in the mouth. The most widely used and best-established type.
Non-enzymatic. Rely on mechanical cleaning plus mild abrasives. Fine, but you lose the residual action.
With chlorhexidine. Stronger antibacterial action, usually reserved for dogs with active disease and used on veterinary advice.
Flavours: poultry, malt, beef, vanilla-mint. Poultry and malt are the most reliably accepted. Mint flavours are made for the owner.
Virbac C.E.T. Enzymatic Toothpaste
An enzymatic paste in poultry and malt, designed to be swallowed and to keep working after brushing. Most dogs treat it as a food, which is exactly what makes the first week of training easy.
C.E.T. Oral Hygiene Kit for Dogs
The same paste bundled with a brush, which saves working out which brush to buy. A sensible starting point if you are setting up from scratch.
Brushes
Dual-ended dog toothbrush — a larger head for big teeth, a smaller one for the front and for small dogs. The standard choice, with a long handle that reaches the back teeth without your hand being in the dog’s mouth.
Finger brush — a rubber sleeve over your finger. Easier to start with, more controlled, less effective long term because the bristles are shorter and do not reach the gumline as well. A good week-one tool, not a permanent solution.
Child’s soft toothbrush — works perfectly well and is cheap.
Three-sided brushes — claim to clean multiple surfaces at once. Many dogs dislike the bulk.
Electric brushes — some dogs tolerate them, many object to the vibration. Not necessary.
What matters is soft bristles and a head small enough to work along the gumline.
The two-week introduction
Do not open a dog’s mouth and start brushing. One bad experience produces a dog who leaves the room when the tube appears.
Days 1–3. Let your dog lick paste off your finger. That is the entire session — ten seconds, once a day. The paste becomes a treat.
Days 4–6. Paste on your finger, rubbed briefly along the outside of the front teeth. Lift the lip rather than opening the mouth. Five seconds, then stop and praise.
Days 7–9. Same, working back to the canines and the first cheek teeth. Ten seconds a side.
Days 10–12. Introduce the brush with paste on it. Let them lick it first, then a few strokes on the front teeth.
Day 13 onwards. One side, then the other. Build to thirty seconds per side.
Technique
- Outside surfaces only. That is where most plaque accumulates, and the tongue does a reasonable job inside. Fighting for access to the inner surfaces costs more goodwill than it gains
- 45 degrees to the gumline. The junction of tooth and gum is where disease starts
- Small circular motions, gentle pressure
- Do not open the mouth. Lift the lip with the other hand and brush with the jaw closed
- Prioritise the upper cheek teeth, where tartar builds worst — particularly the large carnassial on each side
- Daily ideally, three times a week minimum. Plaque mineralises into tartar within about 72 hours, which is why frequency beats duration
What it does not replace
Brushing prevents new plaque. It does not remove existing tartar, and it does not treat disease below the gumline.
Most dogs need professional scaling and polishing under general anaesthetic at some point, with full-mouth radiographs, because a substantial proportion of significant disease is invisible above the gumline.
Avoid “anaesthesia-free dental cleaning”: it improves appearance while doing nothing about the disease, and requires restraining a conscious dog throughout.
Supplements to brushing
VOHC-accepted dental chews have evidence, and are a reasonable addition — with the calories counted.
Greenies Teenie Dental Dog Treats
A dental chew with a texture designed for the tooth to sink into. Match the size band to your dog’s weight and subtract the calories from their daily allowance.
Water additives and gels vary enormously — look for a VOHC seal rather than marketing.
Dental diets with larger, fibre-aligned kibble have evidence. Ordinary kibble does not clean teeth.
If your dog will not tolerate it
Some dogs genuinely will not, and forcing it damages the relationship without cleaning anything.
Options: a finger brush, a dental wipe, a water additive, a dental diet, VOHC chews, and more frequent professional cleaning.
But before concluding your dog will not tolerate brushing, check whether the mouth is sore. A dog with existing periodontal disease is refusing because it hurts — and after a dental, many of those dogs accept brushing without complaint.
