As a dog owner, you want to be sure you are making your dog’s health a priority. Taking them to the vet for checkups, feeding them high-quality food, and having regular grooming sessions are great ways to keep your pup healthy and happy.
However, a dog’s dental health can often get overlooked. A dental water additive is an easy way to help keep your dog’s mouth healthy. While these products shouldn’t replace annual dental cleaning by your vet or regularly brushing your dog’s teeth at home, they’re beneficial supplements that support good oral health.
We gathered our favorites in this list with reviews to help you choose the best one. Your dog will be on their way to cleaner teeth and fresher breath in no time.

Buyer’s Guide – Finding The Best Dog Dental Water Additives
Dental disease, or periodontal disease, in dogs is caused by an overgrowth of bacteria in their mouths. Brushing your dog’s teeth, providing dental chews, and having their teeth professionally cleaned are all great ways to keep your dog’s mouth healthy.

Water additives are supplemental products that can help keep things from getting out of control. While they aren’t meant to take the place of all other teeth cleaning methods, they can help your dog have easier teeth cleanings and ward off dental disease.
When choosing the best water additive for your dog, there are a few things to consider before you buy.
Ingredients
Natural ingredients are effective at fighting bacteria that cause bad breath and plaque. Green tea, cinnamon, aloe vera, and ginger all have anti-inflammatory properties that help calm irritated gums.
Chemical additives will also work to clean your dog’s teeth. Glycerin and citric acid are examples of ingredients that may not be natural but do the job. If your dog has stomach sensitivities, they may not be able to tolerate too many added chemicals.
Safety
Always make sure the additive that you choose is safe for your dog to consume. After all, they are ingesting this additive, not just spitting it out as we do with mouthwash. Any artificial sweeteners should be noted in the ingredients. Most of them are safe for dogs to consume. Stay away from xylitol, which is toxic to dogs.
Taste
Dogs don’t want water that tastes too different from what they are used to. This could make them stop drinking altogether. If you find an additive that your dog won’t touch, try switching to another brand.
Many formulas mask their flavors without losing any of the dental health benefits. Odorless, flavorless options are good to try, especially if you have a picky dog.
Do Water Additives Work?
They do but they can’t do everything. When used properly as part of a dental health routine, they have amazing benefits. Some dogs refuse to let you brush their teeth. In this case, water additives are a good everyday tool to help eliminate harmful buildup on the teeth.
If you can brush your dog’s teeth every day, this will help the water additives work even more effectively.
Nothing is perfect, though, and your dog may eventually wind up with plaque and tartar on their teeth. Your vet can determine the right time for professional teeth cleaning.
