At Theodent, we understand that dental professionals are committed to providing the best care for their patients. They want to use effective, safe products supported by scientific evidence. That's why we're proud to offer our line of toothpastes featuring Rennou™. This powerful and non-toxic active ingredient has been clinically proven to significantly outperform standard fluoride toothpaste in occluding dentin tubules and treating hypersensitivity. In fact, data suggests that it takes 71 times more fluoride to produce the same remineralization effects as Rennou™. We work with many dental clinics around the world that trust in the power of Rennou™, and we have a wealth of scientific research to back up our claims. On this page, we invite dental practices to learn more about the clinical benefits of Rennou™ and to consider incorporating Theodent into their practice.

For a list of peer-reviewed studies on the effects of Rennou™ on the enamel, see below.

We encourage you to try Theodent toothpaste and give us your honest feedback. Many patients prefer not to use fluoride in their dental care routine, and our toothpaste is a great alternative for them. We are committed to constantly improving our products and advancing Rennou™ in the marketplace. With Theodent, you can trust that you are getting a high-quality and effective oral care solution.
