Review: Yea it's pricey, but hopefully worth it and cheaper than the dentist. Plus you don't need to use a lot. It tastes fine, I chose the orange flavor because I've had my fill of mint toothpastes. I wish toothpaste brands would make more flavors other than mainly mint. I haven't had any cavities since my last checkup so I assume it's helping but I have no way to know for sure. Sometimes after brushing I'll reapply a small amount, foam it up, and leave to swish around in my mouth for 5 mins. My teeth certainly "feels" stronger after doing that but I don't know if means anything. One issue I did have is that flip cap will get rubbery, stringy gel strands around the opening. Idk if the cap's plug isn't fully sealing the opening or something. Also the flip-cap on mine had a problem where it couldn't snap shut completely. It was always open a tiny bit. I contacted the company and they gave me a replacement tube for free so their support is great. I gave an extra star for that. I just don't get why it's so hard to make a flip-cap. This shouldn't be rocket science. Will I buy it again? Like I said it's pricey, but I probably will as I think it's helpful. I'll certainly price shop around for other comparable products.
Review: Product works great and leaves my teeth feeling clean. I wish it cost a bit less.

## Features

- [WIN THE BATTLE AGAINST TOOTH DECAY]: Do you ever wonder why some of us continue to get cavities despite meticulous 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, as well as other factors. *NEW LOOK and larger 2.4 oz tube (20% more!) formerly called CariFree CTx4 Gel 1100; same great product!*
- [PROTECT YOUR SMILE]: The CariFree citrus 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 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 Gel 1100 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. The CariFree 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 dental 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!
