Integrating preventive oral health with medical care

Our purpose is to improve the oral health of adults with Special Needs, Complex Needs and Geriatric Needs, using a painless, cost-effective treatment of oral dysbiosis (the primary cause of poor oral health). These high risk communities account for 4 in 10 adults.

Their unmet need for better oral health is amongst the largest in pharmaceuticals.



CHX is a pharmaceutical company developing and marketing a new treatment for oral dysbiosis – the primary cause of poor oral health.


Our Medicine

Prevora is a high-strength, long-lasting antiseptic topically applied by the hygienist to the teeth of adults at high risk of poor oral health.


Better Outcomes, Lower Cost

Prevora is a profoundly new approach to oral healthcare. It deals with the cause not the consequence of poor oral health.
