## Description

desertcart.com : CariFree Maintenance Rinse, Grape Flavored, Anti-Cavity Fluoride Mouthwash, Dentist Recommended, Prevents Oral Decay, Freshens Breath, Alcohol-Free, Neutralizes pH (Previously CTx3) : Health & Household

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: Best mouth wash - The best mouthwash for cavity prevention. My dentist recommended this and I’ve been using for years! Cavity free since using.

## Features

- [WIN THE BATTLE AGAINST TOOTH DECAY]: Do you ever wonder why some of us continue to get cavities despite meticulous oral hygiene, whereas others who rarely brush and floss do not? The risk of cavities varies from person to person and is based on eating and drinking habits, hygiene (brushing and flossing), saliva flow, as well as other factors. *NEW LOOK, same great formula! Formerly known as CariFree CTx3 Rinse*
- [PROTECT YOUR ENAMEL]: The CariFree Maintenance Rinse contains 0.05% sodium fluoride, which helps prevent tooth decay and white spots. Evidence shows that fluoride strengthens your teeth and aids in the prevention of dental cavities.
- [NEUTRALIZE pH] Studies suggest that decay is a function of low pH. Maintaining an elevated or neutral pH balance helps to keep your tooth enamel and smile healthy. The CariFree Maintenance Rinse is alcohol-free and contains patented pH+ technology to elevate the pH in your mouth, keeping it balanced. U.S. Patent No. 9,427,384 & 10,143,633.
- [FORMULATED WITH XYLITOL]: The Maintenance Rinse contains 25% xylitol! Xylitol is a naturally occurring, sweet-tasting ingredient found in many types of plants. Research shows that regular use of xylitol-rich products may reduce your risk of dental cavities.
- [DENTIST-RECOMMENDED MOUTHWASH] Maintaining proper dental hygiene and cavity prevention is essential to a happy and healthy smile! The dentist recommended Maintenance Rinse fluoride mouthwash, which actively works to prevent cavities, freshen breath, and elevate pH.

## Questions & Answers

**Q: Is this mouthwash clear in color?**
A: Absolutely clear. I love the grape flavor!

**Q: What are the full ingredients in the grape rinse?  is the grape organic?  what is the pH of the grape rinse?**
A: The full ingredient list for the CariFree CTx3 Rinse Grape is: Water, xylitol, sodium benzoate, potassium sorbate, sodium fluoride, artificial flavor (grape), sodium bicarbonate. The grape flavored rinse does not have natural flavoring it is artificial. However, the CTx3 Rinse in mint does have natural flavoring. The pH of the CTx3 Rinse is an 8.

**Q: Can this be used in a waterpik? What would the ratio be?**
A: I view this item to be a ‘use full strength’ product. It’s simply a product I rinse with twice per week. I use it as I would a mouthwash and I use a regular mouthwash the other days. If I were to use this product in a Waterpik, I would just pour in the amount I wanted to use and begin. I would not dilute. To my knowledge, there is no dilution guide for this product. It’s is a ‘use full strength’ mouth rinse. As a mouth rinse, I use about 1/4 ounce per rinse. A bottle lasts me approximately 32 weeks. Used in a Waterpik, I see this 16 oz bottle being used up very quickly because a waterpik uses approximately 5 ozs of product (water or specific oral rinse) every 30 seconds of use. Hope this is somewhat helpful.

**Q: Is this product ADA certified?**
A: The CariFree product line falls into the professional products category and the ADA does not have a certification for professional products at this time.

### ⭐⭐⭐⭐⭐ Best mouth wash
*by K***E on December 18, 2025*

The best mouthwash for cavity prevention. My dentist recommended this and I’ve been using for years! Cavity free since using.

### ⭐⭐⭐⭐⭐ I am so excited that I finally found a mint-free mouthwash!
*by E***Y on July 26, 2025*

As someone who is in their late 20's and is allergic to mint, I have been stuck using kid's toothpaste and mouthwash my entire life. People make fun of me, and I really wanted an adult toothpaste and mouthwash that will keep my teeth whiter and my breath fresher. I've used cinnamon toothpaste in the past, but I absolutely hated it. It burned my mouth and made me sick (I found out it still had menthol in it). I ordered this product hoping for a saving grace, and it is! It has no menthol on it, but still has flouride and xylitol for teeth/gum health. Plus I am obsessed with the taste! It tastes like an orange creamcicle, and it doesn't burn my mouth! I will be a forever customer of carifree now. I plan on getting their toothpaste as soon as I run out of the kid's bubblegum one I'm using now.
