By the age of three, most dogs have some degree of periodontal disease. It is painful, it is progressive, and it is largely preventable — and brushing is the only home measure with genuinely strong evidence behind it.
Everything else helps at the margins. The brush does the work.

Why brushing beats everything else
Plaque forms on teeth within hours. Left alone it mineralises into tartar within days, and once it has hardened, only professional scaling under anaesthetic will remove it.
Mechanical disruption of soft plaque is the entire game, and only a brush does that properly. Chews, water additives and dental diets reduce accumulation; they do not remove what is already there.
Frequency matters more than technique. Daily brushing is meaningfully effective. Three times a week is worth doing. Once a week is close to decorative.
Dog toothpaste, not human
Dog toothpastes are formulated to be swallowed, flavoured to be appealing, and many use an enzyme system that continues working after brushing.
Virbac C.E.T. Enzymatic Toothpaste
The one most commonly recommended by vets. Poultry flavour is the usual favourite; the enzyme system keeps working between brushings, which is useful on days you miss. A pea-sized amount is plenty.
Brush types
Finger brushes
A soft silicone sleeve over your finger. Best for starting out, for small dogs, and for nervous dogs.
Pros: excellent control, very non-threatening, easy to reach the front teeth. Cons: poor access to the back molars, where the worst disease happens, and your finger is in the dog’s mouth.
Use one for the first few weeks, then graduate.
Long-handled dual-ended brushes
A large head and a small head on one handle, with an angled neck.
Pros: the standard tool. Reaches the back teeth, keeps your hand out of the way, soft bristles do a proper job along the gum line. Cons: takes a little more acceptance from the dog.
This is what most dogs should end up with.
C.E.T. Oral Hygiene Kit for Dogs
A kit pairing enzymatic paste with an appropriate brush, which saves working out what goes with what. A sensible starting point for a household new to brushing.
Three-sided brushes
A head that wraps around the tooth and brushes three surfaces at once.
Pros: fast, and covers the inner surfaces that most owners skip. Cons: bulky for small mouths, and the fit varies a lot with tooth size.
Electric brushes
Some dogs tolerate them, many do not — the vibration and noise are a lot to accept. Not necessary, and not worth the acceptance battle for most households.
Choosing by dog
Toy and small breeds. Small-headed long-handled brush. These dogs have the worst dental disease of any group because of crowding, so they need this most. A finger brush is a reasonable permanent option for very small mouths.
Medium and large dogs. Standard dual-ended brush.
Flat-faced breeds. Crowded, rotated teeth, and a mouth shape that makes access awkward. A small head and patience. Pay particular attention to the crowded front teeth.
Dogs who dislike having their mouth handled. Start with a finger brush and spend a fortnight on acceptance before any brushing happens at all.
How to start, properly
Do not try to brush on day one. Spend a week building acceptance instead.
- Days 1–2. Let the dog lick paste off your finger. That is the whole session.
- Days 3–4. Paste on your finger, touch the outside of the lips and the gums briefly, reward.
- Days 5–6. Lift the lip, rub the outer surface of the big canine tooth with a finger for two seconds. Reward.
- Day 7. Introduce the brush, dry, with paste on it for the dog to lick.
- Week 2. Brush the outer surfaces of one side for ten seconds, then stop and reward.
- Week 3 onwards. Build to all the outer surfaces, both sides, thirty seconds a side.
A chin rest makes all of this dramatically easier, and takes about a week to teach separately.
Technique
- Angle the bristles at about 45 degrees to the gum line
- Small circles, gentle pressure
- The gum line is the target, not the tooth surface
- Thirty seconds a side, daily
- Same time each day — after the evening walk works well as a routine anchor
What about the other products?
Dental chews. Some have real evidence for reducing tartar. They are a useful addition, not a replacement, and they carry calories that need counting.
Greenies Teenie Dental Dog Treats
Size matters with dental chews — a chew too small gets swallowed whole and does nothing. Match the size band to your dog’s weight and take the calories out of the daily ration.
Water additives and gels. Modest effect. Reasonable for dogs that genuinely will not tolerate brushing.
Dental diets. Larger kibble designed to scrub the tooth as the dog bites through rather than shattering. There is decent evidence for the specific products designed this way.
Raw bones. Controversial. They do clean teeth, and they also cause fractured teeth, obstructions and bacterial contamination. Most vets advise against; if you use them, never cooked, never weight-bearing bones from large animals, and always supervised.
Professional cleaning
Home care extends the interval between professional scalings; it does not eliminate them. Under-anaesthetic cleaning allows the area below the gum line to be treated and X-rays to be taken, which is where most real disease lives.
The verdict
Buy an enzymatic dog toothpaste and a dual-ended brush, spend two weeks on acceptance, then brush the outer surfaces daily for a minute. That combination costs very little and will save your dog real pain, and you real money, over a lifetime.
