Why Dental Chews Matter More Than You Think
By age three, over 80% of dogs have some form of dental disease. That statistic came up constantly when I worked as a vet tech in Portland. I cleaned teeth, extracted rotting molars, and watched owners realize they'd ignored their dog's mouth for years. Dental disease doesn't just cause bad breath. It leads to pain, infection, and organ damage as bacteria enter the bloodstream.
Daily brushing is the gold standard, but let's be realistic. Most people aren't brushing their dog's teeth every day. Dental chews bridge that gap. They mechanically scrape plaque while your dog chews, and some include ingredients that chemically inhibit bacteria. They're not a replacement for professional cleanings, but they meaningfully slow disease progression.
Here's what actually works, based on what vets recommend and what I've seen in practice.
What to Look For: VOHC Acceptance
The Veterinary Oral Health Council (VOHC) independently tests dental products and awards an acceptance seal to those that meet their standards for reducing plaque or tartar. Not every good dental chew has a VOHC seal (the testing is expensive), but if a chew does have one, you know it works. I've noted VOHC status for each product below.
Top 5 Dental Chews
1. Greenies Original Dental Treats (Best Overall)
Greenies are the most widely recommended dental chew by veterinarians, and there's good reason. The textured surface mechanically cleans teeth as your dog chews, and the formula includes added vitamins and minerals. They hold the VOHC seal for plaque and tartar reduction.
Both Benny and Maple get a Greenies after their evening walk. Benny's breath improved noticeably within the first two weeks. The treats come in multiple sizes (petite through large), so you can match them to your dog's weight.
The downside? Some dogs with sensitive stomachs have reported digestive issues. Start with one per day and watch for any problems.

Key highlights:
- VOHC accepted for plaque and tartar control
- Available in five sizes for precise weight matching
- Most widely vet-recommended dental chew
- Textured design cleans down to the gumline
Best for: Daily dental maintenance for dogs of all sizes.
2. Whimzees Natural Dental Chews (Best Natural Option)
Whimzees are made from just six limited ingredients with no artificial preservatives, colors, or flavors. The unique shapes (alligators, hedgehogs, toothbrushes) create more surface contact for better cleaning. They also hold the VOHC seal.
What I appreciate about Whimzees is the ingredient list. For dogs with food sensitivities or owners who prefer minimal processing, these are the cleanest option available. They're also vegetarian, which matters for some owners.
The chewing time is impressive. A medium Whimzees keeps Maple busy for 10 to 15 minutes, which is longer than most dental chews last with a power chewer.

Key highlights:
- Only six limited ingredients
- VOHC accepted
- Longer chewing time than most competitors
- Vegetarian and made without artificial additives
Best for: Dogs with food sensitivities or owners who prioritize natural, limited-ingredient products.
3. OraVet Dental Hygiene Chews (Best for Prevention)
OraVet chews contain delmopinol, an active ingredient that creates a barrier against bacteria on teeth and gums. This makes them unique: they don't just clean teeth, they actively protect them after chewing. They hold the VOHC seal.
At the clinic, OraVet was what most of the vets I worked with kept in their own dogs' treat jars. The combination of mechanical cleaning and chemical protection is the closest thing to brushing that exists in chew form.
The downside is price. OraVet costs more per chew than Greenies or Whimzees. They also have a distinctive smell that some owners find unpleasant (dogs don't seem to mind).

Key highlights:
- Contains delmopinol for bacterial protection
- VOHC accepted
- Both cleans and protects teeth
- Recommended by most veterinary dentists
Best for: Dogs with a history of dental problems or breeds prone to dental disease (small breeds especially).
4. Virbac C.E.T. Oral Hygiene Kit (Best Brushing System)
Not a chew, but I'd be doing you a disservice not to include the gold standard of dog dental care. The Virbac C.E.T. kit includes enzymatic toothpaste and a dual-head toothbrush. The poultry-flavored paste fights plaque without requiring rinsing. Most dogs love the taste.
Combining daily Greenies with two to three brushing sessions per week using Virbac paste is the protocol most vets I know use for their own dogs. It's what I do with Benny and Maple.

Key highlights:
- Number one vet-recommended enzymatic toothpaste
- Poultry flavor dogs actually enjoy
- Includes finger brush and standard toothbrush
- No rinsing required
Best for: Owners committed to a complete dental care routine.
5. Oxyfresh Pet Dental Water Additive (Best Passive Option)
If your dog refuses chews and won't tolerate brushing, a water additive is your last line of defense. Oxyfresh is tasteless, odorless, and VOHC accepted. Add it to your dog's water bowl daily. It won't replace mechanical cleaning, but it inhibits bacterial growth and freshens breath.
I recommend this as a supplement to chews and brushing, not a replacement. But for dogs who fight every dental care attempt, it's far better than nothing.

Key highlights:
- Completely tasteless and odorless
- VOHC accepted
- Easiest dental product to use (just add to water)
- Dogs drink it without hesitation
Best for: Dogs who refuse chews or brushing, and as a supplement to other dental care methods.
Building a Complete Dental Care Routine
Our Dog Dental Care Kit bundles the best dental products for a complete oral health routine.
Here's the protocol I follow for my own dogs:
- Daily: One size-appropriate Greenies or Whimzees after the evening walk.
- 3x per week: Brush with Virbac C.E.T. enzymatic toothpaste, focusing on the outer surfaces of the back teeth.
- Daily: Oxyfresh water additive in the water bowl.
- Annually: Professional dental cleaning at the vet.
This combination costs roughly $50 per month and can save thousands in dental extractions over your dog's lifetime.
Warning Signs to Watch For
Schedule a vet visit if you notice any of these:
- Persistent bad breath that doesn't improve with dental chews
- Red, swollen, or bleeding gums
- Loose or discolored teeth
- Drooling more than normal
- Reluctance to eat hard food or chew toys
- Pawing at the mouth
