Best Dental Chews for Dogs 2026: Greenies vs Whimzees vs OraVet
An honest 2026 review of the best dental chews — comparing Greenies, Whimzees, OraVet, and Virbac C.E.T. for plaque, tartar, and breath control, with VOHC certification details.
Best Dental Chews for Dogs 2026: Greenies vs Whimzees vs OraVet
By age 3, 80% of dogs have some form of dental disease. By age 7, the figure is 90%+. Periodontal disease is the most common medical condition in dogs — more common than obesity, allergies, or arthritis. And the consequences are serious: bacteria from infected gums enter the bloodstream and accelerate heart, kidney, and liver disease.
Dental chews are not a substitute for brushing or professional cleanings, but they’re a meaningful tool — if you choose the right ones. The market is full of “dental chews” that are essentially flavored chunks of carbohydrate with marketing claims. The ones that actually work are validated by the Veterinary Oral Health Council (VOHC) and proven in clinical studies to reduce plaque and tartar by measurable amounts.
This guide compares the best VOHC-accepted dental chews in 2026 alongside the most popular non-VOHC options, with honest assessments of which ones earn their reputation.
VOHC Seal of Acceptance: Look for this on dental chew packaging. It indicates the product was tested in controlled clinical trials and proven to reduce plaque, tartar, or both by significant amounts. Without the VOHC seal, claims are mostly marketing.

🥇 #1: Greenies Original Dental Treats
Greenies is the most-studied, most-recommended dental chew in the industry. The original formula has been on the market since 1996 and has hundreds of veterinary studies behind it. The 2020 reformulation improved digestibility while maintaining VOHC acceptance for both plaque and tartar reduction.
How they work: The toothbrush-style ridges physically scrape plaque and tartar as the dog chews. The texture is harder than soft treats but softer than nylon — gentle enough not to damage teeth, hard enough to clean.
Real impact: Clinical trials show 33% plaque reduction and 25% tartar reduction with daily use over 28 days.
Size matters critically: Greenies must be size-matched to your dog’s weight. Too small = choking hazard. Too large = inefficient chewing. Always follow weight chart.
Best for: Most dogs. Default recommendation for daily dental care.
🥈 #2: OraVet Dental Hygiene Chews
OraVet’s unique selling point is Delmopinol — an ingredient that creates a barrier on tooth surfaces preventing bacteria from adhering. This is mechanistically different from purely mechanical-action chews. Studies show OraVet may be more effective than Greenies in dogs with chronic dental disease, though the average healthy dog gets similar results.
Best for: Dogs with active or chronic dental disease, dogs whose Greenies seem to not be working, dental disease prevention in higher-risk breeds (small breeds, brachycephalic).
🥉 #3: Whimzees Brushzees
Whimzees uses a simpler, more natural ingredient list (potato starch, glycerin, malt) without wheat, corn, soy, or chicken — making them suitable for dogs with multiple sensitivities. The plant-based composition is unique among dental chews.
Texture: Lighter than Greenies, more fibrous. Some dogs inhale them too quickly; in that case, use the slow-eater shapes (Toothbrush, Hedgehog) which require more chewing.
Best for: Dogs with chicken or grain sensitivities, owners preferring plant-based options, dogs that need slower chewing.
#4: Virbac C.E.T. VEGGIEDENT
A veterinary-grade dental chew from Virbac (maker of the Cet enzymatic toothpaste). VOHC-accepted, plant-based, no chicken protein. Strong choice for dogs with dietary restrictions.
Best for: Smaller dogs (4 sizes available), chronic dental disease, those wanting veterinary-brand reliability.
#5: DentaLife by Purina (Budget Pick)
VOHC-accepted for plaque reduction (not tartar like the premium picks above). DentaLife is significantly cheaper but does less. Reasonable choice for owners who want some dental benefit at lower cost.
Cost: ~$0.80/day for medium dog (about half of Greenies price)
Best for: Budget-conscious owners, owners using as adjunct to professional cleanings.
#6: Greenies Aging Care
Specifically formulated for senior dogs (7+). Softer texture, joint-supporting ingredients, lower phosphorus for kidney health. VOHC-accepted same as regular Greenies.
Best for: Senior dogs, dogs with sensitive teeth or kidney concerns.
#7: Greenies Grain-Free
Same VOHC-accepted formulation, but using legumes instead of wheat as the binder. Be aware: This puts Greenies Grain-Free in the legume-heavy category that may have DCM associations. For most dogs, original Greenies is preferable; grain-free only if confirmed grain allergy.
Best for: Dogs with confirmed grain allergies only.
#8: Premium Bully Sticks
Bully sticks (dried bull pizzle) aren’t VOHC-tested for dental claims but provide significant chewing time and mechanical tooth cleaning. They’re a longer-lasting alternative to dental chews.
Caveat: Single-piece, not designed for daily dental routine. Best as 2–3 times per week supplement.
Safety: Choking hazard when worn down to small pieces. Watch and remove when smaller than your dog’s swallow size.
Best for: Power chewers who finish dental chews in seconds, supplement to (not replacement for) daily dental routine.

What Dental Chews CAN’T Replace
A common myth: “Daily dental chews mean I don’t need to brush or get professional cleanings.” This is wrong.
Dental chews reduce plaque and tartar by 25–35%. Plaque accumulates daily on teeth. Even with daily chews, 65–75% of plaque buildup remains. Over time, this accumulates as tartar (calcified plaque) that only professional scaling can remove.
The complete dental routine:
- Daily: Dental chew (basic plaque control)
- Daily/weekly: Tooth brushing with enzymatic toothpaste (best home cleaning)
- Annually: Professional dental cleaning under anesthesia (full removal of tartar, gum line cleaning)
Dental chews alone slow disease progression but don’t prevent it long-term. Combined with brushing and professional cleanings, they’re significantly more effective.
How to Read Dental Chew Labels
Real Indicators of Quality
- VOHC Seal of Acceptance — Required for genuine dental benefit claims
- AAFCO complete and balanced statement
- Active ingredients listed (chlorhexidine, zinc, polyphosphates indicate true dental action)
- Texture descriptions (“brushing action,” “ridges,” “texture”) indicate mechanical cleaning
Red Flag Marketing Claims
- “Helps with dental health” without VOHC seal
- “Cleans teeth” with no proof
- “Natural” or “holistic” with no clinical data
- “Reduces tartar” without certification
- Outrageous breath claims (“eliminates bad breath in days”)
Brushing: The Gold Standard
While we’re on dental health, no amount of chews replaces brushing. Daily brushing with enzymatic toothpaste is the single most effective home dental intervention.
Quick Brushing Guide
Toothbrush: Soft-bristle dog toothbrush or finger brush Toothpaste: Enzymatic dog toothpaste (never human — fluoride is toxic to dogs) Timing: Once daily, ideally before bed Duration: 30 seconds per side, 1-2 minutes total
For owners just starting: Practice with your finger and dog-safe toothpaste first. Gradually introduce the brush. Most dogs accept it within 1–2 weeks with patience.
Best Toothbrushes (Brief)
- Virbac C.E.T. Pet Toothbrush: Standard, dual-ended
- PetSmile: VOHC-accepted toothpaste paired with brushes
- Dual-headed toothbrushes: Better for full-mouth coverage
- Vet’s Best Enzymatic Dental Gel: Apply to teeth without brush (lighter intervention)

Professional Dental Cleaning: When Do You Need It?
Even with chews and brushing, professional cleaning is necessary:
Signs your dog needs cleaning soon:
- Visible tartar (yellow or brown buildup at gum line)
- Bad breath that’s consistently worse than normal
- Red, swollen, or bleeding gums
- Dropping food while eating
- Pawing at face or mouth
- Loose teeth
Recommended schedule:
- Small breeds (under 20 lbs): Annual cleaning starting age 2
- Medium breeds: Annual cleaning starting age 3
- Large breeds: Cleaning every 12–18 months starting age 4
- All breeds: More frequently if dental issues develop
Cost: $400–1,000 (includes anesthesia, X-rays, cleaning, sometimes extractions) Pet insurance: Most plans don’t cover routine cleanings. Wellness add-ons may.
Frequently Asked Questions
How often should I give my dog dental chews?
Most VOHC-accepted chews are designed for daily use. Don’t exceed the package recommendation — calories add up fast. A 50-lb dog’s Greenies is ~70 calories, equivalent to 5% of daily food intake.
Are dental chews safe for puppies?
Most are not labeled for puppies under 6 months. Puppy teeth are still developing; let them grow in before introducing dental chews. Use puppy-safe alternatives (Nylabone Puppy Chew) until adult teeth are in.
Can my dog choke on dental chews?
Yes, particularly if size is wrong (too small for the dog) or if the dog inhales chews. Choking hazards from Greenies were a real concern in early formulations; the 2009 reformulation addressed this. Always supervise initial dental chew sessions.
Will dental chews replace brushing?
No. They reduce plaque and tartar by 25–35%, but daily plaque continues to accumulate. The most effective routine combines daily chews + brushing + annual professional cleanings.
My dog won’t eat dental chews. What now?
Try different shapes/flavors. Some dogs prefer Whimzees over Greenies for texture. Try splitting chews into smaller pieces. As a last resort, focus on brushing + professional cleanings.
Are flavored dental chews safe?
Watch for: artificial colors (often unnecessary), xylitol (NEVER — toxic to dogs), corn syrup (questionable). VOHC-accepted brands generally use safe ingredients.
My senior dog has lost teeth. Should they still chew?
Yes. Greenies Aging Care or Whimzees softer chews are safe for senior dogs with reduced dental capacity. Consult vet about specific concerns.
Can dental chews actually treat existing dental disease?
Dental chews help prevent NEW disease and slow progression. They do NOT treat existing tartar buildup — that requires professional cleaning.
Are there “natural” alternatives to dental chews?
Raw bones are controversial (some vets endorse, others don’t). Carrot sticks and apple slices provide minor mechanical cleaning. Coconut oil has been claimed but lacks evidence. The reality: VOHC-accepted chews are scientifically validated; “natural” alternatives mostly aren’t.
Do bully sticks count as dental chews?
Not in the VOHC sense, but they do provide mechanical tooth cleaning during chewing. Good as supplements, not replacements for VOHC chews.
Our Final Recommendation
For most dogs, Greenies Original is the smart default. VOHC-accepted for both plaque and tartar, decades of clinical research behind it, reasonable price, multiple sizes.
For dogs with chronic dental issues, OraVet is the upgrade — different mechanism (Delmopinol barrier) can be more effective for stubborn cases.
For sensitive dogs with allergies, Whimzees Brushzees is the best plant-based option.
For seniors with diminished chewing, Greenies Aging Care is the specialized variant.
For budget shoppers, DentaLife is acceptable (plaque-only) at ~half the price.
Whatever you choose, remember: dental chews are a tool, not a cure. Combined with daily brushing and annual professional cleanings, they meaningfully extend your dog’s healthy life. Without those supplements, they only slow disease progression.
Dental disease is preventable. Most owners learn this too late — when a 6-year-old dog needs $1,500 in extractions. Start early, build the routine, and your dog will keep their teeth (and avoid systemic disease impact) for life.
