Most pet owners know they should be thinking about their dog’s or cat’s teeth. Fewer know that ozone-based dental care has been used in human dentistry for decades — and that the same science now applies directly to pet oral health.
At Pearly Whites for Pets, we recently added two products by Ozone Apothecary to our in-studio lineup: the Ozonated Glycerin 50% and the Ozone Oral Gel. Both are formulated with medical-grade ozone, built from clean ingredients, and designed for daily home use between cleanings.
This post covers what ozone is, what the research says about its use in dental care, and exactly how to use each product for your dog or cat.
What Is Ozone and How Does It Work?
Ozone (O3) is a molecule composed of three oxygen atoms. Unlike standard oxygen (O2), it is highly reactive — and that reactivity is precisely what makes it effective against harmful microorganisms.
When ozone contacts a bacterial cell wall, it oxidizes and disrupts it. The result is that the cell dies. Viruses, fungi, and certain parasites are vulnerable to the same mechanism. What makes this particularly relevant for dental health is that bacteria cannot develop resistance to ozone the way they can to antibiotics. There is no known biological pathway for a microorganism to adapt around oxidative cell destruction. The mechanism is purely physical and chemical.
This property has made ozone a subject of serious study in human dentistry since the 1990s. A 2024 peer-reviewed paper published in Frontiers in Veterinary Science (PMC11053877) examined ozone specifically as an alternative to conventional antibiotics and antiseptics in veterinary dentistry — with promising findings for its use in reducing periodontal pathogens without disrupting healthy oral tissue.
Ozone in Pet Dentistry: What the Research Says
Dental disease is the most common health problem diagnosed in dogs and cats. By age three, an estimated 80% of dogs and 70% of cats show some signs of dental disease. Plaque hardens into tartar, tartar causes gum inflammation, and untreated gum inflammation leads to tooth loss and systemic health complications.
Conventional approaches to managing oral bacteria at home — enzymatic toothpastes, chlorhexidine rinses — have their limitations. Chlorhexidine, while effective, can cause tissue staining, taste aversion in animals, and does not discriminate between harmful and beneficial bacteria. Many pets refuse enzymatic products entirely.
Ozone-based products operate differently. According to a review published in ScienceDirect (Ozone therapy in veterinary medicine):
- Ozone selectively targets pathogenic bacteria without significantly harming the surrounding healthy tissue
- It reduces the bacterial load in the oral cavity measurably, even with short contact times
- It does not leave residue or produce harmful byproducts — it reverts to oxygen after it reacts
- It has anti-inflammatory properties that support gum recovery in areas of existing irritation
Veterinary ozone specialists, including contributors to the American Holistic Veterinary Medical Association (AHVMA), have noted growing clinical adoption of ozone as a complementary tool in animal dental care, particularly in practices that prioritize avoiding unnecessary antibiotic use.

Why Ozonated Products Are Well-Suited for Pets
Several properties make ozone-based dental care practical for home use with animals:
No taste resistance. Most pets tolerate ozone-infused products well because the products themselves are either tasteless and odourless (as with the Glycerin) or subtly sweet (as with the Gel). The likelihood of refusal is significantly lower than with bitter antiseptic products.
No rinsing required. Pets cannot rinse and spit. Ozone-based products designed for topical gum application do not require rinsing — they are applied directly and left in place. At the concentrations used in the products below, this is both safe and effective.
Safe if ingested in small amounts. At the dilutions used in dental care products, ozonated glycerin and ozonated oil are safe for ingestion. This is a practical consideration for any product used inside an animal’s mouth.
No antibiotic resistance concerns. For pets who receive regular veterinary care, avoiding unnecessary antimicrobial exposure is an increasingly discussed topic. Ozone achieves its antibacterial effect mechanically rather than chemically, which means it contributes nothing to antimicrobial resistance patterns.
Product 1: Ozonated Glycerin 50% by Ozone Apothecary
Price: $59.99 | Available in-studio
The Ozonated Glycerin 50% contains three ingredients: certified organic glycerin, sterile water, and organic Vitamin E. It is produced in small batches in Michigan using medical-grade ozone and is third-party tested for quality and purity.
Glycerin serves as an effective carrier for ozone because it is viscous, stable, and clings to tissue surfaces long enough for the ozone to act. At a 50% concentration diluted with sterile water, it delivers ozone to the gum line without the irritation potential of higher-concentration formulas.
Key product details:
- 2 fl oz (59 ml) in a dropper bottle for precise application
- 100% certified organic ingredients
- Infused with pure medical-grade ozone
- Proprietary formula extends shelf life
- Third-party tested for quality and purity
- Store in the refrigerator or a cool, dry place away from sunlight
Ingredients: Organic Glycerin, Sterile Water, Organic Vitamin E
Product 2: Ozone Oral Gel by Ozone Apothecary
Price: $49.99 | Available in-studio
The Ozone Oral Gel is built around ozonated sunflower seed oil — a delivery medium that penetrates gum tissue more deeply than water-based formulas. Sunflower seed oil has inherent antimicrobial properties of its own, and when combined with medical-grade ozone, the effect is compounded.
The gel also contains linalool, a naturally occurring plant compound found in lavender and other botanicals. Linalool has documented anti-inflammatory and immune-modulating properties, making it a complementary ingredient in a product targeting inflamed or irritated gum tissue.
The formula is subtly sweet, which significantly improves acceptance in dogs — a practical advantage that matters when daily application is the goal.
Key product details:
- 2 fl oz (59 ml) in a squeeze tube for controlled application
- Formulated by scientists with ISO-certified quality controls
- Safe for both pets and people
- Ozonated sunflower seed oil as the primary active ingredient
- Contains linalool for added anti-inflammatory support
Ingredients: Water, Ozonated Sunflower Seed Oil, Flavoring, Glycerin, Carbomer, Polycarbophil, Sodium Hydroxide, Sodium Saccharin, Glyceryl Caprylate, Tocopherol, Ascorbyl Palmitate, Disodium EDTA, Limonene, Linalool
How to Use Each Product at Home
Neither product requires a toothbrush. Both are designed for direct topical application to the gum line. Consistency matters more than the amount used — small amounts applied regularly outperform larger amounts used infrequently.
Using the Ozonated Glycerin 50%
- Apply with the dropper. Place 1 to 2 drops directly along your pet’s gum line — upper and lower, on both sides of the mouth.
- Alternatively, use a soft cloth or fingertip. Apply a small amount to a clean cloth or the tip of your finger and gently run it along the gums.
- Once daily is sufficient. Before bed is an ideal time, as reduced salivation overnight allows the product to remain in contact with the gum tissue longer.
- No rinsing required. Leave the product in place and allow it to work.
- Store correctly. Keep the bottle refrigerated or in a cool, dark location. Ozonated products degrade when exposed to heat and direct sunlight.
The product is tasteless and odourless, which means most dogs and cats accept it without resistance. Start with a small amount to allow your pet to get comfortable with the routine.
Using the Ozone Oral Gel
- Apply a pea-sized amount to the gum line. Use a fingertip or a clean applicator to place the gel directly on the gums.
- No brush needed. The gel adheres to tissue on its own — no brushing motion is necessary.
- Restrict water for 60 minutes after application. This allows the ozone to remain active at the application site without being diluted.
- Apply once daily. Evening application is recommended for the same reason as the Glycerin — lower salivary flow improves contact time.
- The gel has a subtly sweet flavour. Most dogs accept it well. For cats, start with the smallest amount possible and build the routine gradually.
Used together, the Glycerin and the Gel complement each other. The Glycerin penetrates quickly and delivers ozone broadly across the gum surface. The Gel’s oil-based formula provides deeper, sustained contact — particularly useful for areas showing redness or sensitivity.
Where to Get Them
Both products are available exclusively in-studio at Pearly Whites for Pets. You can pick them up at your next cleaning appointment or ask about them when you book.
Studio locations carrying these products:
- Toronto
- Barrie
- Elora
Both products work best as part of a regular dental care routine. A professional cosmetic cleaning removes existing tartar and buildup that at-home products cannot address on their own. Once your pet’s teeth are clean, ozone-based maintenance helps extend the time between visits and keeps the gum tissue healthy in between.

Frequently Asked Questions
Are these products safe for cats?
Yes. Both the Ozonated Glycerin and the Ozone Oral Gel are safe for cats. The Gel is formulated to be safe for both pets and people. For cats, a smaller amount and a gradual introduction to the routine typically yields the best results.
Can I use these products if my pet has never had a professional cleaning?
You can, and the ozone will still have an antimicrobial effect. However, if significant tartar is present, the physical buildup will limit how well any topical product can reach the gum tissue beneath it. A professional cleaning first gives the ozone direct access to the surface it needs to work on.
How soon will I see results?
Ozone works on contact, but visible improvements in gum colour and breath typically become apparent within two to four weeks of consistent daily use.
Do these products replace professional cleanings?
No at-home product replaces a professional cleaning for tartar removal — that requires physical scaling. These products are designed to complement professional care, not substitute for it.
Where do I store them?
The Ozonated Glycerin should be refrigerated or kept in a cool, dark place. The Ozone Oral Gel can be stored at room temperature away from direct sunlight. Both products maintain potency longer when heat and light exposure are minimized.
Both Ozone Apothecary products are available in-studio at our Toronto, Barrie, and Elora locations.
