Review: Excellent if you understand the science behind it. - CariFree offers a carefully thought out line of products geared more earnestly towards improving your oral health than any other company I have encountered. I have rather bad teeth and so am extremely careful with them, and put a lot of effort into finding the best products; therefore I settled on CariFree. There are a number of reasons why this is absolutely superior to ordinary mouthwashes such as those from Crest or Listerine. 1) This is alkaline. People often think that your teeth get back because of sugar; this is not the case. The sugar feed bacteria which then metabolize it to produce acid. It is therefore quite obviously desirable to neutralize this acid, which spikes after eating any food but particularly after eating/drinking sugary or acidic drinks (sugar free sweets are often full of acids to give a "sour" flavor). Most mouthwashes are actually acidic, as you can find upon a quick google search; according to Frey Smiles' blog, Listerine is around pH 4 and Crest Pro-Health around 4.7. Neutral is pH 7. CariFree is pH 8. 2) This has no alcohol. Alcohol is generally not good for you; it's been linked with oral cancer, and definitely can cause dry mouth. Also, it just feels nasty in your mouth. 3) This is antibacterial without staining. Xylitol is a generally effective antimicrobial, antiviral, and antifungal agent. Some studies do say you should not eat xylitol, but this is a rinse, not a gum. The other main antimicrobials are alcohol and cetylpyridinium chloride. Alcohol is bad for the reasons we've mentioned; CPC, on the other hand, can cause awful tooth staining (and it did this for me). 4) This has fluoride. Many rinses do not- you have to look carefully on the package. Tooth enamel is a mineral that consists of calcium, phosphate, and hydroxide ions. In solution, as in your saliva, these ions are constantly popping off and on, but at a very low rate (acidity increases this rate, however). Fluoride ions are more electronegative than hydroxide ions, and so they pop back in instead of hydroxide and hold the structure together more tightly (decreasing the rate at which they pop off). In terms of usage, I also enjoy its flavor, and the fact that it isn't full of useless or possibly harmful dyes, scents, or other additives like most other mouthwashes. It's pretty straightforward: a bunch of really important ingredients that work together well. I also might add that although this product is very expensive, it was developed off real science; the likes of Listerine are products that have been sold in forms very similar to their current form for years. CariFree has a hard time competing with these big companies, but they do offer better products. Finally, I'd recommend looking into their remineralizing toothpaste. As I mentioned, your enamel has three ions that exist in a solubility equilibrium in your saliva: calcium, phosphate, and hydroxide (replaced by fluoride). It makes sense, therefore, that just adding one of these ions is not enough if you want to actually strengthen your teeth. CariFree's toothpaste contains bioavailable sources of calcium and phosphate ions, allowing your tooth enamel to actually rebuild, rather than just dissolve at a lower rate. I hope this helps you all. Review: Poison-free - When I started paying more attention to product ingredients, I saw that this mouthwash was mostly free of harmful additives. It also tastes great and leaves a healthier feel in your mouth. ## Features - Dentist-Recommended Fluoride Rinse: CariFree Fluoride Rinse is recommended by dentists to help prevent cavities and promote good oral health.

There are also no animal-based ingredients in any of our products. **Q: Hey Seller, are you selling fake product? There’s a review that’s concerning. Burden is now on you to prove you’re selling authentic product.** A: Thank you for the great question! No, we are not selling a fake product we are both the manufacturer and the distributor of all CariFree products. We have had to make small changes to packaging over the past year to keep our products in stock due to issues with our supply chain. However, I can confirm we are the brand owner of this product line. If any of our customers are concerned they can reach out to us, we're happy to ease any confusion. I hope that helps and thank you for shopping with and supporting CariFree! **Q: Does the mouthwash work for reducing cavities if you don’t also use the corresponding gel toothpaste?** A: The CTx3 Rinse can be used with one of our gels or on its own. However, to see the best results, we suggest using it with either the CTx4 Gel of the CTx3 Gel. Both CariFree gels and the CTx3 Rinse have an elevated pH, and the addition of the Nano HA and fluoride in the gels work well together. **Q: What is the exact Ph value of the ct4 rinse** A: The pH of the CariFree rinses is 8! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent if you understand the science behind it. *by T***. on January 4, 2016* CariFree offers a carefully thought out line of products geared more earnestly towards improving your oral health than any other company I have encountered.

It also tastes great and leaves a healthier feel in your mouth. ### ⭐⭐⭐⭐⭐ Dentist Recommended and Easy to Use Daily *by R***K on May 4, 2026* I’ll keep it simple since reviews aren't allowed to make medical claims. My dentist pointed me to this rinse because ph neutral. I drink a lot of tea which is slightly acidic. The taste is stronger than I expected, but not in a bad way. It’s got a minty flavor without that harsh burn you get from alcohol-based rinses, which I appreciate. Leaves your mouth feeling clean without that “just nuked my taste buds” feeling. I’ve been using it as part of my normal routine and it’s easy to work into the day. There is a mild aftertaste but it's not bad. It's definitely strong enoguh to use as mouthwash. Bottle and cap are straightforward. Overall, if you’re looking for a non-alcohol mouthwash option with a solid minty taste, this one is worth trying. ## Frequently Bought Together - CariFree Maintenance Rinse, Mint Flavored, Anti-Cavity Fluoride Mouthwash, Dentist Recommended, Prevents Oral Decay, Freshens Breath, Alcohol-Free, Neutralizes pH (Previously CTx3) - Boka Fluoride Free Toothpaste Nano Hydroxyapatite, Helps Remineralize, Appropriate for Sensitive Teeth, Whitening - for Adult, Kids Oral Care - Ela Mint Flavor, 4 Fl Oz 1Pk US Manufactured - PUR Gum | Aspartame Free Chewing Gum | 100% Xylitol | Natural Spearmint Flavored Gum, 55 Pieces (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/21422473-maintenance-rinse-fluoride-mouthwash-mint-alcohol-free-16-oz](https://www.desertcart.jp/products/21422473-maintenance-rinse-fluoride-mouthwash-mint-alcohol-free-16-oz) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-28*
