It may be a chore, but keeping your dogs' teeth clean is vital to their health, since periodontal disease is the most commonly diagnosed doggy health problem. In addition to regular brushing, dental chews can help maintain your dog's teeth by rubbing away plaque. Two of the most popular are OraVet Hygiene Dental Chews and Greenies Dog Dental Care Chews

Given to dogs once per day, each of these chews are designed to remove tartar and plaque from your dog's teeth. That helps prevent teeth problems and periodontal disease, which can evolve into kidney and liver disease if left untreated. 

After a comprehensive comparison between the two top dental chews, we have good news: either are likely to help improve your dog's oral health. They're both approved by veterinarians, and they've each earned a spot on our list of best dental chews. But if we had to pick just one winner...

Our Winner

OraVet Hygiene Dental Chews

You can't go wrong with either of these—and doing anything to help your dog's teeth is certainly better than nothing—but our favorite is OraVet Hygiene Dental Chew. Those chews include delmopinol, which can protect your dog's teeth from further bacteria accumulation. 

Greenies lack delmopinol, but its chews do provide a wider selection of flavors and uses. For you, it might just come down to which one your dog prefers. Ultimately, the better chew will be the one you use.

OraVet Hygiene Dental Chews for Medium Dogs

OraVet Hygiene Dental Chews for Medium Dogs


Who It’s For: Dog owners who want an easy way to help clean their dogs' teeth. OraVet's biggest selling point is its inclusion of delmopinol, which coats a dog's teeth to ideally prevent the buildup of bacteria that, in turn, leads to more plaque and tartar. The product's chewy texture helps remove plaque and tartar from the teeth.

Individually wrapped to ensure freshness, the chews should only be given to dogs once per day. They're accepted by the Veterinary Oral Health Council (VOHC) for tartar removal, and the chews should eliminate bad breath, too.

OraVet vs. Greenies Results

Design and Functionality

Winner: OraVet

OraVet gets the edge here for both plaque and tartar removal as well as the bacteria prevention from the delmopinol. That's a lot of peace of mind from just one treat per day. 

Again, that's not to say the Greenies chew isn't bad. By most accounts, it's an excellent, vet-recommended option, too. It may even be better if you're trying to manage your dog's weight or improve their stinky breath.   


Winner: Greenies

You can get a 36-pack of the Greenies chews for the same (or cheaper) price as the 30-pack OraVet chews. It's minor, sure, but six additional days of chews ain't nothing. That's why Greenies gets the nod here.  

As mentioned before, Greenies also offers a wide variety of dental chews while OraVet only provides its one chew in different sizes. 


Winner: Tie

Anytime you introduce a new treat or food to your pup, make sure you keep an eye on their digestion as they make the switch. A minority of online reviewers reported their dogs experiencing vomiting and diarrhea after trying each of the chews, so you want to be aware just in case. (Green poop was another side effect.)

You'll also want to make sure your dogs are eating the right size of chew according to their weight. Make sure they're not biting off too-large pieces either.

Every dog's digestive system is different, so it's always a good idea to check with your veterinarian before switching to a new product.
