Greenies Dental Treats Review: Do They Actually Clean Teeth?

By the Clean Fluff Club team ยท Hosted by Bo. Updated October 10, 2026. Picked by what's in it.

Greenies Original Teenie Dental Treats

Yes, for dogs who won't let you brush.

  • Worth it if: Toy and small breeds

  • The catch: Small dogs need supervising, so stay in the room while he chews.

  • Skip it if: Your dog is bigger than a toy breed. Greenies Original Regular Natural Dental Dog Treats are sized up for 25 to 50 lb dogs.

Different mess, different pick

The short answer

Yes, for dogs who won't let you brush. Greenies carry the VOHC seal for plaque and tartar, which means the maker submitted trial data showing they reduce both. They don't replace brushing or vet cleanings, and they only work if your dog chews them instead of gulping. Pick the size for your dog's weight and count the calories.

In this guide

"Dental" on a bag is a word. A VOHC seal is data. Greenies have the seal for plaque and tartar, which puts them in a small club of chews that showed results in trials, not just a toothbrush cartoon on the package.

How we reviewed: the VOHC accepted-products list and the product details.

What the VOHC seal actually means

The Veterinary Oral Health Council accepts a product only after the maker submits trial data showing it reduces plaque or tartar. Greenies Original are on that list for both. The list is public, so you can check any chew at vohc.org before you trust the bag.

What it doesn't mean: that a chew replaces brushing or your vet's dental cleanings. It slows buildup between them.

Who should buy them

  • Yes: dogs whose owners can't or won't brush every day. That's a lot of dogs.
  • Yes: dogs who actually chew a treat instead of inhaling it.
  • Maybe not: dogs on a strict diet. These count toward daily calories, so ask your vet.
  • No: gulpers. A chew that goes down in two bites does little. Supervise, or skip.
  • Probably unnecessary: if you already brush daily.

How to give them so they work

  1. Pick the size for your dog's weight on the package. Too small invites gulping.
  2. One a day, every day. The benefit is slow and adds up.
  3. Watch the first few. If your dog swallows big chunks, size up or switch to a different texture.
  4. Cut back elsewhere. Count the chew in the day's treats.
  5. Keep the vet cleanings. A chew is maintenance, not a reset.

Small dogs: Greenies Teenie

Greenies Teenie are the same VOHC-accepted chew in a toy-breed size. The catch: small dogs still need supervising, and with treats this small it's easy to give too many.

The catches

  • Not a toothbrush. It slows plaque and tartar. It doesn't remove what's already hardened on.
  • Calories add up, especially for small dogs.
  • Gulpers get little benefit.

If your dog won't chew it

A water additive like Oxyfresh goes in the bowl with no chewing at all. It's tasteless and odorless, so pets drink normally. The catch: it does less than brushing or a VOHC chew, so treat it as a backup, not the plan.

Oxyfresh Premium Pet Dental Water Additive

Also great

Oxyfresh Premium Pet Dental Water

Best for: Pets who won't tolerate any oral care

More options: VOHC-accepted dental chews and toothpaste and toothbrush kits.

Our verdict

Worth it for dogs who won't tolerate brushing and who actually chew. The VOHC seal is real evidence, not marketing. Pick the right size, count the calories, keep your vet's cleanings, and skip them for gulpers.
