Which dog dental supplement is best?

You might brush your teeth morning and night, floss and rinse with mouthwash, but are you remembering your canine companion’s dental health? Dog dental supplements play a part in reducing plaque and tartar that can lead to gum disease and can help keep your pup’s mouth healthy.

The question is, which dog dental supplement is up to the task? VetriScience Laboratories Perio Support Dental Health Powder is an excellent choice for most dogs, as it’s palatable and easy to mix with food. 

What to know before you buy a dog dental supplement

Dental supplement type

The majority of dog dental supplements come in powder form. These can be mixed in with food so they’re easy to administer to your dog. Supplements in tablet form can be just as effective but may be harder to get your dog to consume. You can also find liquid additives that are either mixed with food or added to water.

Those added to water are generally tasteless or flavored to make them palatable, but they often aren’t as effective as other types of supplements and may simply serve to cover bad breath rather than resolving dental issues. Although they aren’t really supplements, there are also dog dental chews and other dental treats that you can buy.

Active ingredients

The active ingredients in dog dental supplements are what make them work. These ingredients vary depending on the supplement you choose, and some are more effective than others. Kelp is a common ingredient as it contains a beneficial bacteria, Bacillus licheniformis, that breaks down the bacterial biofilm on teeth that turns into plaque.

Other active ingredients include various enzymes that support dental health, fragaria from strawberries that softens existing plaque and prevents new buildup and minerals called zeolites that aid in stopping new plaque deposits from sticking to the teeth.

What to look for in a quality dog dental supplement

VOHC approval

The Veterinary Oral Health Council puts its seal of approval on products that prevent plaque and tartar buildup on dogs. To be awarded VOHC approval, products must meet a set of predetermined standards, so its seal of approval is a good sign that the product does what it says it does. 


If you’re concerned about artificial additives and controversial chemicals in dog dental supplements, you’ll be pleased to know that you can find some all-natural formulas. 


Avoid any dog dental supplements labeled as homeopathic. Herbal remedies contain measurable quantities of herbs that may have therapeutic effects, while the ingredients in homeopathic remedies may be so highly diluted in water that they’re no longer detectable.

How much you can expect to spend on dog dental supplements

Most dog dental supplements cost $10-$40, depending on factors such as the supplement type and package size. 

Dog dental supplement FAQ

Do I still need to brush my dog’s teeth if I give them a dog dental supplement?

A. Dog dental supplements are just one weapon in the war against tooth and gum problems in dogs. Although these supplements can reduce plaque and improve dental health, they aren’t a substitute for brushing. If you can brush your dog’s teeth, you should do so in addition to using supplements. If your dog simply won’t let you brush their teeth, you can use dental chews and similar, plus supplements, but this isn’t as effective as brushing.

Can you reverse tooth decay in dogs? 

A. No, once a dog’s teeth start to decay, there’s no way to reverse it and the dog in question will likely eventually need to have the offending teeth removed. Luckily, tooth decay isn’t all that common in dogs due to the shape of their teeth and their largely sugar-free diet. The majority of dental issues in dogs are caused by gum disease. If you don’t care for your dog’s teeth, plaque and tartar build up on the teeth, getting under the gumline and causing inflamed gums. Eventually, these gum issues can lead to dental abscesses and tooth loss, which is painful and unpleasant for dogs and can contribute to further health issues.
