Dr. Perry Ratcliff, one of America's leading periodontists and experts on dental health and gum disease, and a team of leading dental professionals created CloSYS in 1991.

During Dr. Ratcliff's 50 plus years of clinical practice, he discovered that stabilized chlorine dioxide helped to significantly reduce the harmful bacteria in the mouths of his patients. This discovery led him to create the patented formula Cloralstan™, the active ingredient that makes CloSYS uniquely different and effective.

What We Do

We make CloSYS Oral Health products to help people live healthier lives.
