Review: Great toothpaste for my sensitive teeth, good mint flavor, cleans well, and has those nano particles which supposedly help remineralize teeth (maybe that’s why it helped my sensitivity?). However, there’s other options available that offer the same style of ingredients for less…and I trusted this specific brand (Carifree) for years before finding the new brand I prefer (due to price).
Review: I ordered this toothpaste because I was TIRED of going to the dentist to find out I always had cavities in between my teeth. I'm an advocate teeth brusher and I floss! I was so aggravated that even after having a good teeth regimen I STILL had cavities. After spending TOO MUCH money on dental work, I did some research on how cavities happen to people who actually brush their teeth regularly. I discovered the hidden truths about regular toothpaste which includes Crest and Sensodyne, which I was once I faithful user of. Unlike other toothpaste, this CariFree toothpaste doesn't include sugar or anything too rough of abrasive for your teeth. It also balances the PH of your mouth which NONE of the other toothpaste does. This is the closest you can get for prescription-grade toothpaste on desertcart... period. I've tried ALL the flavors from CariFree and everything has a really good flavor. The grape one doesn't foam in your mouth but the Citrus and Mint one does (and most mimics regular toothpaste). This toothpaste starts off as a gel and goes into a foam-like texture when brushing. It doesn't tingle your mouth (there's any alcohol in it) and it's great for teeth sensitivity because I have really sensitive teeth. I even have used this immediately after experiencing any tooth sensitivity and it helps alleviate the discomfort. Another fun fact is that I had "SOME" cavities and my dentist suggested I fill them even though they weren't big (meaning they wanted to make money off me for small fillings). Instead of filling "potentially" problematic tooth decay, I opted to use this toothpaste, went back to another dentist 6-months later and they told me I had ZERO cavities. Yes, after another dentist told me and showed me I had 3 cavities on the x-ray, I went to another dentist and took x-rays and they told me I had no cavities. So either the 1st dentist didn't know what they were talking about or this toothpaste made a dramatic difference. I have been using this toothpaste every day for the past six months and have not had any new cavities or teeth discomfort. Although the price is more pricer, you save on dental work, so I would recommend. You ONLY need a small amount of this gel-like toothpaste, so one tube can last up to a month. I would use it with their mouthwash as well since you wouldn't want to reverse the benefits of having this toothbrush.

## 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 product. Larger 2.3 oz. tube (20% MORE)!*
- [PROTECT YOUR SMILE]: CariFree Fluoride Free Gel (formally called CTx3 Gel) contains nano-hydroxyapatite, a natural component of saliva and the mineral your teeth are made of. The nano-hydroxyapatite in this gel is bio-available and mimics the size and shape hydroxyapatite that is naturally found in saliva.
- [FORMULATED WITH XYLITOL]: The Fluoride Free Gel 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.
- [PATENTED pH+ TECHNOLOGY]: Studies suggest that tooth decay is a function of low pH. Maintaining an elevated or neutral pH balance helps to keep your tooth enamel and smile healthy. CariFree Fluoride Free Gel contains patented pH+ technology to elevate the pH in your mouth, keeping it balanced. U.S. Patent NO. 9,427,384 & 10,143,633.
- [MAKE AN INVESTMENT IN YOUR HEALTH]: Are you tired of dental visits that lead to fillings, crowns, and root canals? We understand the frustration, and it's this frustration that led Dr. Kim Kutsch DMD to develop oral care products that worked for his patients. Produced in Albany, Oregon, our gels are safe to use every day, travel size-approved, non-abrasive for sensitivity, and scientifically proven to aid your dental health. Our mission is to help our customers become cavity-free for life!

*by C***G on 2 August 2025*

I love this toothpaste and have used the mint for myself and my husband and grape for my kids for the past year and a half. My husband and kids have weak enamel and despite brushing multiple times and day and glossing. They have now had multiple dentist appointments (every 6 months) with no new cavities. It really does work so well. Giving 4 stars instead of 5 because you used to be able to get free shipping with prime membership and now it costs $9 to ship a single tube of the fluoride free, even though it’s already $17 for the small tube. I don’t know if it’s an Amazon issue or a Carifree issue, but if you’re paying for prime something this tiny and lightweight should certainly continue shipping for free. Very disappointed and will look for other places to buy rather than purchasing on Amazon.
