Proof, Not Promises

Anyone can say "reduces plaque." We had to prove it.

Almost every water additive on the shelf makes the same promise. Almost none of them have ever been tested. HealthyMouth® was put through independent clinical trials — and passed.

What Does VOHC® Accepted Actually Mean? Veterinary Oral Health Council

To earn the VOHC seal, a product must pass controlled, blinded clinical trials using real cats and real plaque measurements — not marketing claims. Most brands never even attempt it.

That's why so few water additives carry the seal. When you see it, it means one thing: this actually works.

Vet examining cat's teeth for signs of dental disease

What Happens If You Wait

Plaque never stops getting worse.

Bad breath is usually just the beginning. Left untreated, plaque keeps building until it turns into painful — and expensive — dental disease.

Plaque hardens into tartar Soft plaque hardens within weeks and can no longer be removed with brushing alone.

Gums become inflamed Redness, swelling, and discomfort appear as gum disease begins to develop.

Pain, tooth loss, and costly treatment Advanced dental disease often leads to extractions under anesthesia — procedures that can run into the thousands.

The good news: plaque in its early stage is still reversible — and stopping it daily takes nothing more than your cat drinking water.

Frequently Asked Questions

Everything you need to know about HealthyMouth® for cats.

There are two ways to use it. As a drinking water additive, add 1 tsp (5ml) per 1 quart (1 liter) of water and change out like regular water. As a food topper, add 1/8 tsp (0.61ml) directly onto your cat's food once per day. Introduce slowly over 2 weeks with a smaller dose to allow your cat to adjust.

HealthyMouth® is virtually tasteless and odorless when diluted properly in water — most cats won't notice it at all. The Wild Salmon flavor variant adds a mild palatability boost for cats that are more selective. If your cat seems hesitant, try introducing it slowly over 2 weeks with a smaller dose.

Clinical trials showed over 80% plaque reduction after 30 days of consistent daily use. Many cat owners notice fresher breath within the first 1–2 weeks. For best results, use daily without skipping — HealthyMouth® works continuously as long as it's part of your cat's routine.

The Veterinary Oral Health Council (VOHC) is an independent organization that awards its seal only to products that meet strict, pre-set standards of plaque and tartar control in clinical trials. It's the gold standard in veterinary dental care — similar to the ADA seal for human dental products. HealthyMouth® has held this seal since 2011.

Yes — HealthyMouth® is formulated for daily, lifelong use. It's made with 100% human-grade superfoods and natural extracts, contains no pharma chemicals, artificial ingredients, alcohol, sugar, sodium, fat, or gluten. It's backed by long-term safety studies and does not disrupt the mouth's natural flora.

No — HealthyMouth® is a daily home care product, not a replacement for professional veterinary cleanings. Think of it like brushing your own teeth — essential for daily maintenance, but you still visit the dentist. Used consistently, it can significantly reduce the frequency and severity of professional cleanings needed.

Yes, but remove the filter first. Water fountain filters are designed to absorb impurities, and they will also absorb HealthyMouth®'s active ingredients — reducing or eliminating effectiveness. Simply remove the filter while using HealthyMouth® and replace it when you stop.

Based on recommended daily use for one cat: the 8 oz lasts up to 6 months ($0.38/day), the 16 oz lasts up to 12 months ($0.33/day), and the 36 oz lasts up to 24 months ($0.24/day). Actual duration may vary slightly based on whether you use it as a water additive or food topper.

If your cat doesn't accept HealthyMouth® when used as directed, we'll make it right. No fine print, no hassle. We've stood behind every bottle we sell for 18+ years because we're confident in the product. Contact our support team and we'll take care of you.

HealthyMouth® is made with 100% natural, human-grade ingredients and is gentle enough for daily use. We recommend consulting your veterinarian before starting any new supplement for very young kittens. For adult cats, it's safe for continuous, lifelong use.
