Dental disease affects over 80% of dogs over the age of three. Left untreated, periodontal disease causes chronic pain, tooth loss, and bacteria that can enter the bloodstream and damage the heart, kidneys, and liver. Regular brushing is the gold standard — but daily dental chews can provide meaningful supplemental benefit.
The critical qualifier: not all dental chews work. The Veterinary Oral Health Council (VOHC) independently evaluates dental products and awards their seal to those that actually demonstrate plaque or tartar reduction in controlled studies. If a product doesn’t have the VOHC seal, its dental claims are unverified marketing.
This guide focuses only on VOHC-accepted products and products with compelling independent evidence.
The VOHC Seal: Why It Matters
The VOHC is a US-based organization (affiliated with veterinary dental boards) that accepts products that have been tested in independent studies and shown to statistically reduce plaque or tartar. The seal means clinical evidence exists. No seal means the manufacturer made a claim without independent verification.
A significant number of popular dental chews (including some major brands) do NOT hold the VOHC seal. We won’t name names, but if you’re buying dental treats specifically for dental health, check the VOHC accepted products list at VOHC.org.
1. Milk-Bone Daily Dental Chews — Best Budget VOHC Option
ASIN: B001HCJJD8 | ~$12.99 for 40 sticks
Check price on Amazon →{rel=“nofollow sponsored”}
Milk-Bone Daily Dental carries the VOHC seal, making it one of the most accessible and affordable clinically-validated dental chew options. The flexible ridges on the stick design are intended to flex against the tooth surface as the dog chews, reaching beyond the gumline.
At roughly $0.32 per chew for a medium-sized dog, these are the most budget-friendly VOHC-accepted option we found. Dogs accept them readily — the taste is formulated for palatability.
Pros:
- VOHC accepted (clinically proven tartar reduction)
- Most affordable option in this category
- Widely available everywhere
- Dogs accept the taste readily
Cons:
- Adds calories (~88 calories per stick for medium dogs)
- Contains artificial flavors
- Not suitable for dogs with wheat allergies (contains wheat)
2. Greenies Original — Most Popular VOHC Dental Chew
ASIN: B000P5WOPQ | ~$26.99 for 27 treats (large)
Check price on Amazon →{rel=“nofollow sponsored”}
Greenies are the most purchased dog dental treat in the US, and they carry the VOHC seal. The unique rubbery texture is specifically designed to flex and abrade the tooth surface. Most dogs are very enthusiastic about Greenies — they’re clearly formulated with palatability in mind.
The brand has addressed previous safety concerns (early formula versions caused digestive blockages in rare cases) — the current formula is softer and digestible.
Pros:
- VOHC accepted
- Most popular dental chew — billions served
- Highly palatable — most dogs love them
- Multiple sizes available
- Digestibility improved with current formula
Cons:
- Higher calorie content (~107 calories per large Greenie)
- More expensive per chew than Milk-Bone
- Not appropriate for dogs with wheat/gluten sensitivities
3. Virbac CET VeggieDent Chews — Best Grain-Free VOHC Option
ASIN: B004S5ZMSW | ~$28.99 for 30 chews
Check price on Amazon →{rel=“nofollow sponsored”}
For dogs who can’t have grains (or who react poorly to Greenies), Virbac CET VeggieDent is the alternative with VOHC acceptance. These are Z-shaped vegetable-based chews containing inulin and rice flour. They’re also free of animal proteins, making them appropriate for dogs with meat protein sensitivities.
Virbac is a professional veterinary brand — these are often sold through veterinary offices, which adds credibility.
Pros:
- VOHC accepted
- Grain-free and animal-protein free
- Often available through vets (professional recommendation)
- Good digestibility
Cons:
- Less palatable than Greenies for many dogs
- More expensive
- Harder to find at regular pet stores
4. Enzymatic Toothpaste + CET Chews — Best Professional System
ASIN: B000A0PQOD | ~$14.99 for 30 chews
Check price on Amazon →{rel=“nofollow sponsored”}
Virbac C.E.T. chews use a dual-enzyme system (glucose oxidase and lactoperoxidase) that creates an antibacterial effect against oral bacteria. The rawhide-based chews provide mechanical abrasion while the enzymes work chemically.
These work via a different mechanism than the above options — the enzymes specifically target the bacterial film (plaque) before it mineralizes into tartar. When used daily, they’re considered one of the most effective non-brushing dental options by veterinary dentists.
What Dental Chews Can and Cannot Do
Can do:
- Reduce tartar by 20-60% versus no dental care (VOHC-level evidence)
- Reduce some bacterial load
- Provide supplemental daily dental care between brushings
Cannot do:
- Replace tooth brushing (brushing is still 2-3x more effective)
- Remove existing tartar (requires professional dental cleaning under anesthesia)
- Treat existing dental disease
The hierarchy of dental care:
- Professional dental cleaning (by a vet)
- Daily tooth brushing with enzymatic toothpaste
- VOHC-accepted dental chews
- Water additives (modest evidence)
- Dental diets
Calorie Awareness
A 60-lb dog’s daily caloric allowance is roughly 900-1200 calories. A single large Greenie is ~107 calories — about 9-12% of daily calories. If you’re giving dental chews daily, reduce the regular meal accordingly. Dental treats should account for no more than 10% of daily calories.
FAQ
Q: Can I use dental chews instead of brushing? A: Dental chews are a useful supplement, not a replacement. Brushing removes plaque before it mineralizes; no chew does this as effectively.
Q: My dog swallows dental chews without chewing. Are they still effective? A: No — the mechanical abrasion of chewing is central to how they work. If your dog gulps them, try a larger size that requires more chewing, or switch to a different texture.
Q: At what age should I start dental chews? A: Dogs 6 months and older (after adult teeth have come in) can begin dental chews. Check size guidelines carefully for puppies.
Our Verdict
Any VOHC-accepted dental chew is better than nothing. For budget-conscious owners: Milk-Bone Daily Dental delivers clinically validated results at the lowest cost. For maximum palatability and popularity: Greenies. For grain-free needs: Virbac CET VeggieDent.
But remember: dental chews are a supplement to, not a replacement for, brushing and regular veterinary dental cleanings.
