Top 5 Probiotic & Prebiotic Toothpastes in Canada, 2026
Short answer: no toothpaste sold in Canada under the "probiotic" label contains live probiotic bacteria the way a yogurt or a supplement does. What is actually on the shelf are prebiotic pastes (Tom's of Maine, Revitin), which feed the bacteria already in your mouth, and hydroxyapatite pastes (RiseWell, Boka), which target enamel rather than bacteria. The clinical evidence is early but real: a 2025 systematic review and meta-analysis pooled 12 randomized trials of biotic toothpastes and found less plaque and less bleeding on probing at three months. No trial has shown they prevent cavities. Fluoride status matters more than the biotic claim, and four of the five pastes below are fluoride-free.

Top Picks Summary
Tom's of Maine Prebiotic Toothpaste
Tom's of Maine Prebiotic Anticavity is the only fluoride toothpaste in this list, which makes it the one option here with established anticavity protection. The prebiotic angle is inulin, a soluble fibre that feeds the bacteria already in your mouth; it does not add live cultures. The formula skips artificial flavours, colours and preservatives, and at around $6 it is the cheapest paste in the group by a wide margin.
RiseWell Balancing Toothpaste
RiseWell's toothpastes are built around hydroxyapatite, the mineral that makes up tooth enamel — 10% micro-hydroxyapatite in the original Mineral formula and 15% nano plus micro in the PRO version. It is the fluoride alternative with the strongest evidence behind it: an 18-month randomized trial in adults found a hydroxyapatite paste non-inferior to fluoride for caries prevention, and Health Canada has licensed a fluoride-free nano-hydroxyapatite toothpaste as anticavity. Non-inferior is not superior, and the Canadian Dental Association still recommends fluoride, so check with your dentist before switching if you have a history of decay.
Boka Ela Mint Natural Toothpaste
Boka Ela Mint is a fluoride-free paste built on nano-hydroxyapatite, with essential oils and aloe vera. Hydroxyapatite is the one fluoride alternative with randomized-trial support — an 18-month adult trial found it non-inferior to fluoride for caries prevention — but it is not a stronger anticavity agent than fluoride, and this formula carries no fluoride at all. The Ela Mint is mild rather than sharp, and it comes in a 113 g tube.
Revitin Natural Toothpaste
Revitin is a non-foaming prebiotic mint tooth gel. It is fluoride-free and contains no hydroxyapatite, so it has no proven anticavity or remineralizing action — the case for it rests on the microbiome-support idea, which has plaque and gum-bleeding evidence at three months but nothing on cavities. It is SLS-free, dye-free, gluten-free and made without added sweeteners, which makes it a reasonable pick if foaming pastes irritate your mouth. At about $30 it is the most expensive paste in this list.
Hello Activated Charcoal Teeth Whitening Toothpaste
Hello Epic Whitening is an activated-charcoal paste with coconut oil, and it sits in this category by shelf adjacency rather than chemistry — it contains no probiotics or prebiotics. A 2017 JADA review found insufficient evidence that charcoal whitens beyond removing surface stains, and charcoal pastes generally test more abrasive than standard fluoride pastes. It is fluoride-free, vegan and SLS-free, with no artificial sweeteners or dyes, in an 82 mL tube.
Prebiotic and hydroxyapatite formulas aimed at the oral microbiome and enamel — only one of the five contains fluoride.
Understanding Probiotic Toothpaste
What the label promises, and what the trials actually found:
No "probiotic" toothpaste sold in Canada delivers live bacteria that colonize the mouth. These products are prebiotic (inulin or plant extracts that feed existing oral bacteria) or postbiotic (heat-killed strains) — a real distinction if you are buying on the microbiome claim.
A 2025 systematic review and meta-analysis of biotic toothpastes pooled 12 randomized controlled trials and found lower plaque scores and less bleeding on probing at three months. Those are gum-health measures, not cavity measures.
No trial has shown that a probiotic or prebiotic toothpaste prevents cavities, cures bad breath, or reverses gum disease. Treat those claims as marketing, and treat none of these pastes as a substitute for a dental visit.
Fluoride remains the one anticavity ingredient with decades of evidence behind it, and the Canadian Dental Association continues to recommend it. Of the five pastes here, only Tom's of Maine contains fluoride.
Hydroxyapatite is the credible fluoride-free alternative: an 18-month randomized trial in adults found a hydroxyapatite paste non-inferior to fluoride for caries prevention, and Health Canada has licensed a fluoride-free nano-hydroxyapatite toothpaste as anticavity. Non-inferior is not superior.
Charcoal is not a biotic ingredient at all. A 2017 JADA review found insufficient evidence that charcoal whitens beyond removing surface stains, and charcoal pastes test more abrasive than standard fluoride pastes.
Frequently Asked Questions
Do probiotic toothpastes actually work?
Partly. A 2025 systematic review and meta-analysis pooled 12 randomized controlled trials of biotic toothpastes and found reduced plaque and less bleeding on probing at three months. No trial has shown they prevent cavities, and none of the pastes sold in Canada delivers live bacteria that colonize the mouth — they are prebiotic or postbiotic formulas.
Which probiotic or prebiotic toothpaste should I buy in Canada?
If cavity protection is the priority, Tom's of Maine Prebiotic is the only fluoride paste in this list and the cheapest at about $5.97. If you want a fluoride-free option, Boka Ela Mint at $17.99 uses nano-hydroxyapatite, the one fluoride alternative with randomized-trial support, and it carries the highest rating here at 4.6.
Which of these toothpastes contain fluoride?
Only Tom's of Maine Prebiotic Anticavity, which uses sodium fluoride. Boka Ela Mint, Revitin, RiseWell and Hello Activated Charcoal are all fluoride-free. A fluoride-free paste gives you no proven anticavity protection unless it contains hydroxyapatite at an effective concentration.
Is Boka Ela Mint Natural Toothpaste worth $17.99?
It has the highest rating in this list at 4.6 and hydroxyapatite is the best-evidenced fluoride alternative, but a standard fluoride toothpaste costs about a third as much and has stronger anticavity evidence.
Conclusion
If cavity risk is what you are solving for, the fluoride paste is the safe default and the hydroxyapatite pastes are the reasonable fluoride-free substitute. The prebiotic and charcoal options are better judged on taste, texture and ingredient preference than on any proven clinical outcome. Talk to your dentist before dropping fluoride if you have a history of decay.
