## 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 dietary habits, hygiene (brushing and flossing), saliva flow, and the oral environment.
- [PROTECT YOUR ENAMEL]: The CariFree CTx4 Gel 1100 contains .24% sodium fluoride (1100 ppm), which stops cavities as well as prevents tooth decay and white spots. Evidence shows that fluoride strengthens your teeth. The CariFree CTx4 Gel 1100 also contains nano-hydroxyapatite, a natural component of saliva, and the mineral your teeth are made of. In combination, these work together to help protect your smile.
- [FORMULATED WITH XYLITOL]: The CTx4 Gel 1100 contains 25% xylitol! Xylitol is a naturally occurring, sweet-tasting ingredient found in many types of plants. Oral microbes cannot use xylitol for energy. Because of this, xylitol may prevent bacteria from consuming sugars and producing acids that cause decay. Research shows that regular use of xylitol-rich products may reduce your risk of dental cavities.
- [PATENTED pH+ TECHNOLOGY]: Studies suggest that decay is a function of low pH. Prolonged periods of low (acidic) pH in your mouth provide a perfect environment for cavity-causing bacteria to grow. Maintaining an elevated or neutral pH balance helps to keep your tooth enamel and biofilm healthy. The CariFree CTx4 Gel 1100 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 prevent cavities. Our mission is to help our customers become cavity-free for life!

## Questions & Answers

**Q: how many applications does one 2oz tube contain?**
A: The 2 oz tube typically lasts about a month if used twice daily with the recommended pea size amount for each application.

**Q: Does it contain milk or dairy?**
A: The active ingredient in CariFree CTx4 gel is sodium floride 0.24%.  I see not evidence of milk/dairy products in the inactive ingredients.  For a more definitive answer, consult with your dentist.  My dentist and my ENT doctor both recommended this product, but I am not allergic to milk products.

**Q: Is this low foaming? Foam irritates my lips and mouth.**
A: Great question! This product does contain a foaming agent, if you prefer to avoid foaming please see our CariFree CTx3 Gel, in the grape flavor!

**Q: Q to seller:  “the ctx4 gel 1100 contains 25% xylitol!” why is xylitol the last ingredient? is the gel 25% xylitol by weight? thank you.**
A: Xylitol is the last ingredient on the list because we label the ingredients in alphabetical order as it is required for this type of product by the FDA.  Yes, the 25% xylitol is based on weight.

### ⭐⭐⭐⭐⭐ Review
*by R***J on 25 August 2025*

This stuff is expensive, so don't use it like you'd use crest sparklefun or whatever. You don't need to use a lot. I don't like that all the other hydroxyapatite toothpastes are filled with hippie bullcrap about being fluoride-free. The effectiveness of hydroxyapatite pastes hasn't been proven long-term yet, and basic fluoride toothpaste didn't seem to be doing it for me on its own (also a lot of them had harsher detergents that left me with canker sores.) So, this product is perfect for hedging my bets with old and new dental technology. As for results, I think it's done well for me. I don't have hot or cold sensitivity and haven't had a toothache in a long time. Remember well: nothing will work if you don't brush morning and night. Nothing. Well, 'cept dentures, but you still have to clean those if you don't want a stink mouth.
