Dental chews are one of the biggest pet treat categories, and the packaging almost always promises fresher breath and cleaner teeth. Some products have evidence behind those claims; many do not. Picking a chew that does real work comes down to a handful of checks: an independent seal, the right size and hardness, sensible calories, and realistic expectations about what a chew can do.

How dental chews work
Most chews work mechanically. As your dog gnaws, the chew’s texture scrapes soft plaque off tooth surfaces before it hardens into tartar. Some add ingredients intended to bind calcium in saliva and slow tartar formation. The key word is plaque: chews can slow buildup on reachable surfaces, mostly the back teeth used for chewing, but they cannot remove established tartar or treat gum disease beneath the gumline. That needs a veterinary dental cleaning.

The Veterinary Oral Health Council (VOHC) reviews study data from manufacturers and awards its seal to products that meet preset standards for reducing plaque, tartar or both. It is the closest thing to an independent verification in this category. Seal-holding products are listed on the VOHC website, which is worth checking because packaging claims are not regulated in the same way. A chew without the seal is not necessarily useless, but you are taking its claims on trust.
Check 2: Size it correctly
A chew that is too small can be swallowed whole or in large chunks, which is a choking and blockage risk. A chew that is too big gets abandoned. Most brands size by weight.
| Dog size | Typical weight | Chew size guidance | Watch for |
|---|---|---|---|
| Toy | Under 10 lb | Petite or toy sizes only | Crowded teeth that trap food; gentle textures |
| Small | 10 to 25 lb | Small size | Gulpers; supervise |
| Medium | 25 to 50 lb | Regular or medium | Aggressive chewers may need the next size up |
| Large | 50 to 100 lb | Large | Swallowing big end pieces |
| Giant | Over 100 lb | Largest available | Many products top out too small for giant breeds |
When in doubt, size up, and take away the last small piece before it can be swallowed whole.
Check 3: Hardness and tooth safety
Very hard items like antlers, bones, hooves and hard nylon are common causes of fractured teeth, especially the large upper cheek teeth. A widely used rule of thumb: if you cannot dent the chew with a thumbnail or bend it slightly, it is probably too hard. Good dental chews have some give, so teeth sink in and the texture wipes the tooth surface.
Check 4: Calories and ingredients
Dental chews can be surprisingly calorie dense, sometimes 70 to over 250 kcal each for larger sizes. For a 20 lb dog that needs roughly 500 to 600 kcal a day, one big chew can be a significant share. Treats, chews included, should generally stay within about 10 percent of daily calories. Reduce meals accordingly and check the calorie count on the pack. Dogs with food allergies need ingredient lists checked just like their food.
Check 5: Chewing time and your dog’s style
A chew only works while your dog is chewing it. If your dog swallows one in 30 seconds, it is not doing much for teeth. Look for shapes with ridges and nubs that take several minutes, or try a larger size. Always supervise.
Chews work best as part of a routine
Brushing daily with pet toothpaste remains the most effective home care. Chews, water additives and dental diets are useful supports, especially for dogs that will not tolerate brushing. Bad breath, red gums, loose or broken teeth, drooling or pawing at the mouth mean it is time to see your vet, since dental disease is painful and chews cannot fix it.
FAQ
How often should I give a dental chew?
Most products are designed for once daily use, since plaque rebuilds within about 24 to 48 hours. Account for the calories in your dog’s daily food.
Are dental chews safe for puppies?
Many brands specify a minimum age, often around six months, when adult teeth are in. Check the label and choose a softer, size-appropriate product.
Bottom line
A dental chew that actually works carries a VOHC seal, is sized to your dog’s weight with room to spare, passes the thumbnail hardness test, fits into daily calories and takes your dog several minutes to finish. Use it alongside brushing, not instead of it, and see your vet for any signs of dental pain or disease.
