In 1991 Dr. Perry Ratcliff, one of America's leading periodontists and experts on dental health and gum disease, and a team of leading dental professionals formed Rowpar Pharmaceuticals Inc. to study, and improve oral care. They set out to create over-the-counter products that could do more than just the usual of freshening breath and whitening teeth. 

During Dr. Ratcliff's 50 plus years of clinical practice, he discovered that Cloralstan™ (stabilized chlorine dioxide) which helped to significantly reduce the harmful bacteria in the mouths of his patients. Bacteria that's linked to larger systemic health issues. He knew the health fight had to start in the mouth. So his discovery led him to create the uniquely different, highly effective, and extremely gentle line of oral care products now called CloSYS (pronounced; klōw·sis)

What We Believe

Our purpose hasn't changed. We emphatically believe better overall health through better gum and mouth health has to be the focus of oral care. Whiter teeth and fresher breath are great, we do those too, but they won't help you be well and stay well. 

Oral care needs to be about your health first and foremost. We start by not faking you out with the painful burning, excessive foaming and nonsense ingredients that are nothing more than cover ups. Because the mouth is the gateway to the rest of the body CloSYS is passionately focused on delivering gentle yet exceptional gum, teeth, and mouth health to help people live healthier lives.
