Yes — with an asterisk. Dental chews that carry the Veterinary Oral Health Council (VOHC) Seal of Acceptance have demonstrated reduced plaque and/or tartar buildup in controlled trials, so the category isn't pure marketing. But the effect is modest, it requires daily use, and no chew can scrape off tartar that has already hardened or clean below the gumline. Chews are a supporting player in dental care, not the star. Here's what the evidence actually supports, how to tell a real dental chew from a candy bar in disguise, and how to use chews safely.
How Dental Chews Are Supposed to Work
Most dental chews rely on two mechanisms. The first is mechanical: as your dog gnaws, the chew's texture scrubs the tooth surfaces, disrupting the soft plaque biofilm before it hardens. Longer chew time means more scrubbing, which is why chews designed to take minutes rather than seconds tend to perform better. The second is chemical: many formulas include enzymes or other ingredients intended to slow bacterial growth or plaque formation. Chewing also stimulates saliva, which naturally helps rinse the mouth.
This is genuinely plausible — and it mirrors how regular chewing helps wild canids keep teeth cleaner than you'd expect. But "plausible" and "proven" are different things, which is where the VOHC seal comes in.
What the Evidence Actually Shows
The Veterinary Oral Health Council awards its Seal of Acceptance only to products shown in trials to reduce plaque and/or tartar accumulation — and its accepted-products list includes a full category of edible chew treats. That's the closest thing the industry has to an independent quality filter, and it's worth taking seriously: a chew with the seal has cleared a bar that most "dental" treats on the shelf never attempt.
What the seal does not mean is equally important. It certifies reduced accumulation of plaque and tartar — not removal of existing tartar, not gum disease treatment, not a substitute for professional care. VCA Animal Hospitals puts it plainly: special chew toys and treats "may also help reduce or delay plaque and tartar build-up" — help, not solve. The realistic picture: a daily VOHC-accepted chew slows the buildup between cleanings. It doesn't reset the clock.
The "Give" Test: Avoiding Fractured Teeth
Here's a safety rule every chew buyer should know. VCA warns that most tooth fractures happen when dogs chew objects that are too hard — ice cubes, bones, hard nylon chews, antlers, hooves — and states the rule this way: any chew toy or dental treat should bend and "give" upon compression. Press the chew with your thumbnail before you buy it. If it doesn't dent, don't give it to your dog.
Fractured teeth are genuinely common and genuinely serious: a complicated fracture exposes the pulp (nerves and blood vessels), and the fix is extraction or a root canal by a veterinary dentist. A dental chew that breaks teeth is worse than no dental chew at all. This is one reason very hard "long-lasting" chews are a poor trade — the longer a dog works on something rock-hard, the higher the risk.
What Chews Can't Do
Setting expectations honestly, because chews are oversold more than almost any dental product:
- They can't remove hardened tartar. Once plaque mineralizes, no chew, wipe, or brush takes it off — professional scaling and polishing under anesthesia is required, per VCA.
- They can't clean below the gumline. The destructive part of periodontal disease happens under the gum, unreachable by any chew.
- They can't replace brushing or wiping. Direct mechanical cleaning of the tooth surfaces and gumline remains the at-home gold standard.
- One chew a week does nothing. The trials behind the VOHC seal involve daily use. Sporadic chews are treats, not dental care.
Pairing a daily chew with a quick wipe session covers both bases — the chew handles passive scrubbing while you relax, and the wipe lets you target the gumline directly. RunyePet Dental Finger Wipes →
How to Pick a Safe, Effective Chew
Use this checklist in the treat aisle:
- Look for the VOHC seal. Check the VOHC accepted-products list — it's the only independent efficacy standard in the category. No seal doesn't automatically mean a product is useless, but a seal means someone verified the claim.
- Pass the give test. It should dent under thumbnail pressure. Reject anything rock-hard.
- Size it right. The chew should be large enough that your dog must gnaw it, not swallow it whole. Undersized chews are a choking and obstruction risk — when in doubt, size up.
- Count the calories. Dental chews are treats, and treats should stay within roughly 10% of daily calories. For small dogs, a large daily chew can be a meaningful share of their diet — ask your vet if you're unsure.
- Supervise, especially at first. Watch how your dog chews: gulpers who try to swallow large pieces need a bigger chew or a different product entirely. Never leave a dog alone with a chew until you know their style.
- Check the ingredient list. Avoid chews with xylitol or other ingredients flagged in our guide to xylitol and sugar in pet dental products.
Common Mistakes
- Treating any crunchy treat as a dental chew. Regular biscuits and treats don't have the texture, shape, or tested formula of a real dental chew. The word "dental" on the bag means nothing without the VOHC seal.
- Giving chews to a dog with existing dental disease. If your dog already has red, bleeding gums or loose teeth, chewing can hurt — and may worsen the problem. Get a vet dental check first, then add chews to the maintenance routine.
- Replacing brushing with chews. This is the most common mistake. Chews are the easiest thing to do and the least effective — use them as backup for brushing or wiping, not a replacement. Our guide to cleaning teeth without brushing shows how to layer methods.
- Ignoring the back teeth. Dogs chew mostly with their premolars and molars, so chews actually clean those well — but the canine teeth and incisors get less action. That's another reason to pair chews with wipes.
When to See Your Veterinarian
Chews are maintenance, not medicine. See your vet if your dog has persistent bad breath, red or bleeding gums, visible tartar buildup, difficulty chewing, or a fractured tooth from a too-hard chew. Remember that over 80% of dogs over age three have some degree of dental disease, according to VCA — regular professional checkups catch what home care can't. The American Veterinary Dental College can help you find a board-certified veterinary dentist if your dog needs advanced care.
FAQ
How many dental chews should my dog get per day?
One per day is the standard for dental benefit — the efficacy trials behind VOHC-accepted products are based on daily use. More than that mostly adds calories without adding dental benefit.
Do dental chews replace brushing?
No. Chews reduce plaque accumulation; brushing (or wiping) actively removes it from the tooth surfaces and gumline. Think of chews as the supporting cast — helpful daily, but not the main act.
Are dental chews safe for puppies?
Many are, but check the label for minimum age and size guidance — puppies need softer, appropriately sized chews, and anything too hard risks damaging developing teeth. Our puppy dental care guide covers what's appropriate at each stage.
My dog swallows chews whole. What should I do?
Size up, supervise closely, or switch approaches — a swallowed chew provides zero dental benefit and creates an obstruction risk. For enthusiastic gulpers, daily wiping is often the safer and more effective routine.
The Bottom Line
Dental chews work — modestly, daily, and only as part of a bigger routine. Buy VOHC-accepted, pass the thumbnail give test, size it right, supervise, and pair the chew with real mechanical cleaning at the gumline. Do that, and chews earn their place.
