Top 5 Fluoride Mouthwash Options in Canada, 2026
Published on Thursday, January 1, 2026
Quick answer: of the five rinses on this page, three are genuine anticavity fluoride rinses — ACT Anticavity, Listerine Total Care Zero Alcohol and Crest Pro-Health Advanced. The Colgate Total Gum Health rinse and the Biotène Dry Mouth rinse are here as companions for gum care and dry mouth; neither is sold as an anticavity fluoride product, so neither substitutes for one. In Canada a fluoride mouthwash is not a cosmetic. Any rinse that claims to prevent cavities is regulated as a non-prescription drug under the Food and Drugs Act and must carry an eight-digit Drug Identification Number (DIN) on the label, searchable in Health Canada's Drug Product Database. A rinse that only freshens breath makes no therapeutic claim, is a cosmetic, and carries no DIN — that number is the fastest way to tell the two apart on the shelf. Concentration is the other fact worth knowing before you buy: daily over-the-counter rinses are 0.05% sodium fluoride (about 225 ppm fluoride), weekly rinses are 0.2% sodium fluoride (about 900 ppm), and 1.1% sodium fluoride at 5000 ppm is prescription-strength. Nothing on this page is prescription-strength.
Top Picks Summary
A daily 0.05% sodium fluoride rinse helps remineralize enamel between brushings — used at a separate time of day, not immediately after toothpaste.
How to choose a fluoride mouthwash in Canada
The label tells you more than the front of the bottle. Six things worth checking:
Look for a DIN. An anticavity fluoride rinse is a non-prescription drug in Canada and must show a Drug Identification Number. No DIN means it is a cosmetic rinse that freshens breath and makes no cavity-prevention claim.
Match the strength to the routine. 0.05% sodium fluoride (~225 ppm) is the daily over-the-counter strength; 0.2% (~900 ppm) is formulated for once-a-week use; 1.1% (5000 ppm) is prescription-only and comes from a dentist or pharmacist.
Use it at a different time than brushing. Toothpaste leaves a more concentrated layer of fluoride behind, and rinsing right after brushing dilutes and washes it away. A fluoride rinse does more good at a separate point in the day, and you should not chase it with water.
Not for children under six. Health Canada and the Canadian Dental Association advise against fluoride mouthwash for young children, who swallow rather than spit; repeated swallowing while permanent teeth are forming raises the risk of dental fluorosis. It should not be swallowed at any age.
Check the alcohol. High-alcohol rinses sting and are a poor fit for dry mouth, for anyone in recovery from alcohol use, and for children. The claim that mouthwash alcohol causes oral cancer is contested and not settled evidence — comfort and dryness are the practical reasons to choose alcohol-free.
Know what it cannot do. A fluoride rinse helps enamel resist decay and can slow plaque buildup, but it does not remove plaque or tartar, does not cure gingivitis, and does not replace brushing and flossing.
Frequently Asked Questions
Does a fluoride mouthwash need a DIN in Canada?
Yes. A rinse that claims to prevent cavities is regulated as a non-prescription drug under the Food and Drugs Act, so it must carry an eight-digit Drug Identification Number on the label and appear in Health Canada's Drug Product Database. A rinse that only freshens breath is a cosmetic and has no DIN.
Which products on this page are actually fluoride rinses?
Three of the five. ACT Anticavity Fluoride Rinse Alcohol Free, Listerine Total Care Zero Alcohol Mouthwash and Crest Pro-Health Advanced with Extra Whitening are all sold as anticavity fluoride rinses. Colgate Total Gum Health is an anti-gingivitis rinse built around cetylpyridinium chloride, and Biotène Oral Rinse is a moisturizing rinse for dry mouth — neither is an anticavity fluoride product.
What strength of fluoride mouthwash should I use?
0.05% sodium fluoride — roughly 225 ppm fluoride — is the standard daily over-the-counter strength, and it is what ACT Anticavity Fluoride Rinse uses. A 0.2% rinse at about 900 ppm is meant for once-weekly use. 1.1% sodium fluoride, at 5000 ppm, is prescription-strength and is not sold over the counter in Canada.
Can I use fluoride mouthwash right after brushing?
It is better not to. Toothpaste leaves a more concentrated layer of fluoride on the teeth, and rinsing immediately afterwards washes much of it away. Use the rinse at a separate time of day, spit it out rather than swallowing, and do not rinse with water afterwards.
Conclusion
Fluoride mouthwash is an addition to brushing and flossing, not a replacement for either, and it is the kind of product where the label — DIN, concentration, alcohol content — tells you more than the marketing. If you have active decay, dry mouth from medication, or orthodontic appliances, ask your dentist whether a prescription-strength rinse is a better fit than an over-the-counter one.
