Mintier Review 2026: The Clean Oral Care Brand Behind the Oil-Based Breath Serum

I've been interested in the mouth tape trend for a while — longer than I've actually tried it, if I'm being honest. The idea that nasal breathing during sleep could improve sleep quality, reduce snoring, and support oral health seemed worth exploring. But most mouth tapes I encountered felt like an afterthought: medical tape slapped in a pretty box.

Then I found Mintier. A Toronto-based, female-founded brand that launched in 2019 with a genuinely novel product — the world's first oil-based breath mint — and has since built out an entire oral care ecosystem around the idea that fresh breath and good oral health should come from clean, thoughtful ingredients.

It's a brand that takes oral care as seriously as the wellness industry takes gut health. And the products are genuinely good.

What Is Mintier?
Mintier is a Canadian oral care brand (est. 2019) founded and led by a female founder in Toronto. They make mouth tape for nasal breathing, oil-based fresh breath serums, stainless steel tongue cleaners, and collagen-infused oral care products — all formulated without sugar or artificial ingredients.

The brand launched with a mission: create a 100% natural alternative to the sugar-loaded, artificially flavored breath mints that dominate the category. The world's first oil-based breath mint was the starting point. Mouth tape — with latex-free, hypoallergenic formulations — came next. Then a full range of supporting products for a complete clean oral care routine.

The brand is sold at Well.ca and National Nutrition, appears in celebrity and influencer partnerships, and has been expanding into pet oral care — a natural (if unexpected) extension for a brand focused on clean-ingredient oral health.

Did you know?Mouth breathing during sleep is associated with increased snoring, dry mouth, dental decay, and disrupted sleep quality. Nasal breathing filters and humidifies air before it reaches the lungs — and mouth tape is one of the simplest interventions for encouraging nasal breathing through the night. Mintier's latex-free, hypoallergenic formulation makes the habit more accessible for people with sensitivities.

Mintier Mouth Tape — from $34.99 (30-count, 1-month supply)

• What it is:Latex-free, hypoallergenic mouth tape for nasal breathing during sleep

• Why it's different:Most mouth tapes use standard adhesives that can irritate sensitive skin. Mintier's hypoallergenic formulation is designed for nightly wear.

• Best for:People who want to explore nasal breathing for sleep quality improvement

Collagen Peptide Mouth Tape — from $50.00

• What it is:An elevated version of their mouth tape infused with collagen peptides

• Best for:The beauty-meets-wellness consumer who wants to maximize the skincare and oral care overlap

• Standout:This is genuinely novel — collagen peptides in a mouth tape is a product concept you won't find elsewhere

Goodnight Kiss Mouth Tape — from $35.00

• What it is:A slightly softer aesthetic variation of the mouth tape line

• Best for:Gift buyers or those who want a more premium unboxing experience

Mintier Fresh Breath Serum — from $25.00

• What it is:An oil-based breath serum — the product that started it all

• Why it matters:Oil-based breath freshening works differently than mint-and-sugar gums or mints. The oil base coats and neutralizes rather than masking with sweetness.

• 100% natural:No sugar, no artificial flavors, no alcohol

Stainless Steel Tongue Cleaner — from $20.00

And the pet water additive? It makes complete sense for a brand whose entire thesis is "oral care deserves clean ingredients" — of course that extends to pets.

FAQ

Q: Is mouth tape safe to use every night?
A: Yes, for most healthy adults nasal breathing is the natural sleep state, and hypoallergenic mouth tape supports this safely. Those with severe nasal congestion or sleep apnea should consult a physician before starting.

Q: What makes the Mintier Fresh Breath Serum different from a regular breath spray?
A: Most breath sprays use alcohol and artificial flavors to mask odor. The Mintier serum uses an oil base that works through a different mechanism — binding to odor-causing compounds and bacterial membranes rather than covering them up.

Q: Is the Collagen Peptide Mouth Tape actually absorbed through the skin?
A: The skin around the mouth is a permeable area. Collagen peptides in topical applications are studied for skin support — Mintier applies this to their mouth tape as part of the beauty-wellness crossover innovation.

Q: Where is Mintier sold besides their website?
A: Mintier is available at Well.ca and National Nutrition, in addition to their direct website at shopmintier.com.

Q: Is the pet water additive safe for all pets?
A: Check the product page for species-specific guidance and consult your vet if your pet has existing health conditions.

Mintier has built a genuinely innovative oral care brand on a clean-ingredient foundation — from the world's first oil-based breath serum to collagen-infused mouth tape, the brand consistently brings something new to a category that has long needed new ideas. If you're ready to apply the same ingredient scrutiny to your oral care that you bring to your food and skincare, Mintier is a great place to start.
