Dental chews vs toothbrushing

4 min readLast reviewed Aug 29, 2026 by JWB

The options

Daily toothbrushing

Mechanical removal of plaque at the gum line with a soft brush and pet-specific toothpaste.

Best for, Every dog and cat, started as early in life as possible.

Pros

  • Directly removes plaque before it mineralises into tartar
  • Reaches the gum line, which is where periodontal disease starts
  • Costs almost nothing per day
  • Lets you notice a broken tooth, a mass or sore gums early

Cons

  • Requires daily consistency to be worth much
  • Needs training, and an untrained adult animal will resist
  • Adds no calories, which some owners find less rewarding to give
  • Human toothpaste is unsafe, so it needs a pet-specific product

Dental chews and diets

Textured chews, treats or kibble formulated to reduce plaque or tartar through mechanical action or additives.

Best for, Animals who will not tolerate brushing, and as a supplement on days brushing is missed.

Pros

  • Almost universally accepted, since animals want to eat them
  • No training required
  • VOHC-accepted products have demonstrated a measurable effect
  • Occupies a dog for a while, which has its own value

Cons

  • Adds daily calories, which matters for a weight-prone animal
  • Most products on shelves carry no VOHC seal and no evidence
  • Hard chews fracture teeth, which is a common and expensive injury
  • Does not reach the gum line the way a brush does

The VOHC seal is the only shortcut

Dental is among the least regulated claims in the pet aisle. Any chew can be described as promoting dental health without any testing behind it. The Veterinary Oral Health Council maintains a register of products that have met defined standards for reducing plaque or tartar, and its seal is the single fastest way to tell a tested product from a marketed one.

Check the register rather than the packaging. If a product is not on it, treat the dental claim as advertising and judge the chew on calories and safety instead.

The hardness problem

Very hard chews are a leading cause of fractured teeth, and slab fractures of the upper carnassial usually mean extraction under general anaesthetic. The rough guide vets use is the thumbnail test: if you cannot make a dent in it with a thumbnail, it is hard enough to break a tooth.

  • Avoid antlers, hooves, bones and hard nylon chews.
  • Match chew size to the dog, so it cannot be swallowed whole.
  • Supervise, and retire a chew once it is small enough to gulp.
  • Count chew calories against the daily ration rather than adding them on top.

Building a brushing habit that survives

Most brushing routines fail because they start with a brush in the mouth. Build it in stages over a week or two, paying at each step, and stop while the animal is still happy rather than when the job is done.

  1. Let the animal lick pet toothpaste off your finger. Repeat until it is looking forward to it.
  2. Touch the outside of the lips and cheeks with a finger, then pay.
  3. Slide a finger along the outer surface of a few teeth. Pay.
  4. Introduce the brush with paste on it, touching one or two teeth only.
  5. Build to the outer surfaces of all teeth. The inner surfaces matter far less, since the tongue does much of that work.

Daily is the target. Several times a week is still worthwhile; once a week does little. Never use human toothpaste, which contains fluoride and often xylitol, both unsafe when swallowed.

How to choose

  • Do both if you can: brush daily, and use a VOHC-accepted chew on the days it does not happen.
  • Animal that tolerates handling: start brushing now, whatever its age.
  • Animal that genuinely will not allow it: VOHC-accepted chews or a VOHC-accepted dental diet, and accept that this is second best.
  • Weight-prone animal: subtract chew calories from meals, or favour a dental diet over added treats.
  • Already smelly breath, red gums or visible tartar: book a veterinary dental assessment. Neither brushing nor chews removes existing tartar or treats disease below the gum line.
