Vet Recommended Dog Dental Chews: Do They Really Work?

Quick answer: Some dental chews genuinely reduce plaque and tartar - but only the ones clinically proven to (look for the VOHC seal). Even the best chews slow build-up rather than remove hardened tartar, so they work best alongside tooth-brushing and a regular professional scale and polish, not as a replacement.

Dental chews are one of the most popular ways owners try to look after their dog's teeth - they're easy, and most dogs love them. But do they actually work, or are they just a treat with good marketing? Here's the honest, vet's-eye view.

What dental chews actually do

A good dental chew works mechanically: as your dog gnaws, the texture scrapes soft plaque off the tooth surface before it hardens into tartar. Some also contain ingredients that slow plaque-forming bacteria. The key word is plaque - the soft film that builds up daily. Chews can help reduce that film, which in turn slows the formation of hard tartar (calculus).

What they cannot do is remove tartar that has already hardened, or clean below the gumline where the most damaging disease sits. No chew reaches there.

Do they work? Look for the VOHC seal

This is where most owners go wrong: many products claim "dental benefits" with no evidence behind them. The reliable shortcut is the VOHC seal — the Veterinary Oral Health Council awards its seal only to products shown in trials to reduce plaque or tartar. If a chew carries the VOHC seal, there's real data behind the claim; if it doesn't, treat the marketing with caution.

What to look for when buying

  • The VOHC seal of acceptance.
  • The right size for your dog - too small is a choking risk, too large won't be chewed properly.
  • Calorie content - chews add up; adjust meals so your dog doesn't gain weight.
  • Avoid very hard chews, bones, antlers and hooves. These are a leading cause of fractured teeth - a painful problem that often needs extraction. A good rule: if you can't dent it with a fingernail or it wouldn't be comfortable to tap on your knee, it's too hard.

Chews are a helper, not a cure

Even with daily chews, plaque still hardens into tartar over time, especially below the gumline. Once that happens, the only fix is a professional dog teeth cleaning  a thorough dental scale and polish under general anaesthesia. Think of chews and brushing as maintenance between professional cleans, not a substitute for them. If you've noticed signs of dental pain in dogs - bad breath, dropped food, red gums - chews won't fix it; book a check.

Frequently asked questions

Are dental chews enough to keep my dog's teeth healthy?

They help, but no chew is enough on its own. Daily brushing plus regular professional cleans is the proven combination; chews are a useful extra.

How do I know a chew actually works?

Look for the VOHC (Veterinary Oral Health Council) seal - it means the product has trial data showing it reduces plaque or tartar.

Can dental chews replace a professional cleaning?

No. Chews slow plaque but can't remove hardened tartar or clean below the gumline, which is where dental disease does its damage.

Are bones or antlers good for teeth?

We don't recommend them — they're a common cause of painful tooth fractures. Choose a softer, VOHC-accepted chew instead.

How to Safely Brush Your Dog's Teeth at Home (Step-by-Step)

By Brandon Tomo • July 7, 2026
Quick answer: Daily brushing with a dog-safe toothpaste (never human toothpaste) is the single best thing you can do for your dog's teeth at home. Introduce it gradually over 1–2 weeks, focus on the outer surfaces of the teeth, and pair it with regular professional dental checks - brushing slows plaque but can't remove hardened tartar below the gumline. Brushing is the gold standard of home dental care, and it's genuinely worth the effort: it removes plaque before it hardens into tartar, the main driver of gum disease. The good news is that almost any dog can learn to accept it if you go slowly. Here's exactly how. What you'll need A dog toothbrush or a soft finger brush (a soft child's toothbrush works for larger dogs). Dog-safe enzymatic toothpaste , usually poultry- or malt-flavoured. Never use human toothpaste. It often contains fluoride and sometimes xylitol , which is toxic to dogs. Dog toothpaste is made to be swallowed safely. Step-by-step: brushing your dog's teeth Let your dog taste the toothpaste. Put a little on your finger and let them lick it off, so they learn it's a treat - not a threat. Touch the lips and gums. Over a few days, gently lift the lip and rub a finger along the outside of the teeth and gums. Reward calm behaviour. Introduce the brush. Add toothpaste to the brush and let your dog lick it, then start touching it to a few teeth. Brush the outer surfaces. Hold the brush at about a 45° angle to the gumline and use small circles. The *outer* surfaces (cheek side) collect the most tartar and are what matter most - don't worry about the inner surfaces early on. Build up gradually. Start with a few seconds and a couple of teeth; over 1–2 weeks work towards the whole mouth, aiming for about 1–2 minutes. Finish with praise or a reward. Keep every session short, calm and positive so your dog looks forward to it. How often should you brush? Daily is ideal. Plaque starts to harden into tartar within a couple of days, so brushing every day (or at least every other day) keeps ahead of it. A few times a week is still far better than nothing. When brushing isn't enough Brushing is brilliant prevention, but it has a limit: once plaque has hardened into tartar - especially below the gumline - no amount of brushing will remove it. At that stage your dog needs a professional canine teeth cleaning : a dental scale and polish under general anaesthesia. If you already see brown tartar, red gums or notice any signs of dental pain , book a dental check rather than relying on brushing alone. Not keen on brushing, or have a dog that won't tolerate it? Vet-recommended dental chews (look for the VOHC seal) are a useful back-up between brushes. How we help at AVH Animal Ark Our team is happy to show you the technique in person and check whether your dog already needs a professional clean. When a scale and polish is needed, we perform it with our iM3 GS Elite dental unit, under safe general anaesthesia with IV fluids and full monitoring, at our Springleaf and Tampines clinics (open 7 days). A scale and polish starts from $550 (blood tests from $250). Frequently asked questions Can I use human toothpaste on my dog? No. Human toothpaste can contain fluoride and xylitol, both harmful to dogs. Always use a toothpaste made for dogs. My dog hates having his teeth brushed - what can I do? Go slower. Spend several days just letting him lick the paste and getting used to your finger on his gums before introducing the brush. Keep sessions short and rewarding. VOHC-accepted chews and a dental diet can help in the meantime. How soon will brushing make a difference? Brushing prevents *new* plaque from hardening, so the benefit is ongoing. It won't remove tartar that's already there - that needs a professional scale and polish. Is brushing enough on its own? It's the best home step, but most dogs still need periodic professional cleanings because brushing can't reach below the gumline.
