Best Dog Dental Water Additives – Benefits and Reviews of Top Additives

It’s easy for us to maintain oral hygiene. Brushing is a part of our daily routine and often the first thing we do in the morning.

If only it were as easy for dogs. 

Because dogs don’t understand the importance of oral health and are really skeptical about us sticking a long brushy thing into their mouths every now and then, it is wrong of us to expect patience.

Thankfully, science has made multiple advancements, and today, we have alternatives such as dog dental water additives that make life easy for us. Otherwise, imagine having to deal with a foul breath every time your dog comes close to you!

So, what are these water additives? Are they safe? Which one can you buy? We are answering all these FAQs in our detailed guide today.

What are Dog Dental Water Additives?

dog dental issues

You can liken these to a mouth wash. They are meant to be added to water for the purpose of rinsing dogs’ mouths. They are fairly new in the market and are starting to catch on. Vets have also started recommending them for dogs that have the following problems:

  • Yellow teeth
  • Bad breath
  • Swollen or inflamed gums
  • Poor appetite 

Dental water additives address two main dental issues that dog face – periodontal disease and tartar buildup. However, it is very important to buy only good quality products because a few may have harmful chemicals in them.

Is it Safe to use Dog Dental Water Additives?

This depends on the product you choose. As aforesaid, a few have harmful chemicals that can cause health issues. Other than that, they are fairly safe. 

The trick is to be informed about the harmful ingredients. Many have, for example, xylitol. This is an artificial sweetener and is harmful to dogs. Choose an additive that has no sweeteners at all or has honey. Artificial colors (Yellow #5 and blue #1), foaming agents (sodium lauryl sulfate), and preservatives (EDTA and parabens) are other ingredients you should steer clear of. 

To ensure complete safety, we recommend that you speak to the vet and buy the additive he/she recommends. Your vet knows your dog’s medical history and can prescribe something that’s not harsh. 

Are Dog Dental Water Additives Good Replacements for Brushing?

Would you rather just use mouthwash every day? We think not. 

It is the same with canines.

These water additives are alternatives but not proper replacements. Any expert would recommend brushing teeth, but we understand it is not always possible. So a regimen of professional teeth cleaning and daily rinse with these additives can promise great dental health.

Naturel Promise Fresh Dental Water Additive

This water additive promises 12 hours of fresh breath and is recommended for daily use. You can use it for dogs and cats of all ages. Here’s why we say it is an excellent product:

  • It is a colorless liquid.
  • It contains only natural and safe ingredients.
  • You can use it daily by adding 1 cup (bottle cap) of the additive into the water bowl.
  • It mainly addresses plaque and tartar. It also gets rid of bad breath. If your dog has any other serious dental issues, you should visit the vet first. 
  • We advise you to give it a few days or weeks to show results. Expecting it to work overnight is wrong.


Even though all these dog dental water additives are available without prescriptions, we strongly suggest that you speak to the vet before deciding anything. While most ingredients are safe, dogs may be allergic or sensitive to a few. Every dog is different, and the needs vary drastically. The vet is the best judge, and it is always ideal to let him/her do the job. 

Also, as much as we would love for it to be true, this is not a replacement for brushing. Brushing has always been the best. This is simply an alternative when all else fails. We hope you exercise caution and do what’s best for your pooch. All the best!
