About us

We are radically improving the dental experience for patients and clinicians.

The Zyris difference

Zyris was founded in 2001 by Thomas R. Hirsch, DDS, his brother James Hirsch, an industrial designer, and Sandra Hirsch, CPA. The genesis of the company was a passionate pursuit of revolutionizing the industry through functional, efficient innovation, in a quest to create positive dental experiences for both patients and clinicians.

We are proud to offer three highly-effective, technologically-advanced, award-winning solutions for minimally invasive, easy-to-use dental isolation—as well as control of the oral environment worldwide.

Our products include:

  • The Isolite® Pro illuminated dental isolation system, with six levels of intra-oral LED illumination, including non-curing amber light.
  • The Isolite® Core non-illuminated dental isolation system for practitioners who choose to work with external light only.
  • The Isolite® Core+, which builds on the Isolite® Core with additional heads and adapters to accommodate higher patient volume. 

All products, including our full line of isolation mouthpieces, are completely compatible and complementary to one another. The mouthpieces (the heart of our technology) comfortably retract the patient's tongue and cheek, protect the patient's airway, and keep the mouth gently propped open with continuous two-channel 360° adjustable suctioning.

Benefits beyond the patient’s chair. By using our Isolite Dental Isolation Systems, clinicians have stated that dental procedures are completed up to 30% faster than using traditional methods of isolation. Faster procedures = more patients = improved productivity and increased revenue for your practice.

Zyris has been awarded a General Services Administration contract (V797P-3233N) that allows qualified federal, state, and local government agencies to purchase Zyris products at special government pricing with pre-determined contract terms and conditions. The Isolite System is a U.S. registered medical device manufacturer specializing in dentistry.

Our mission

Zyris is radically improving the experience of dentistry with category-defining products, educational resources, and community collaboration.

We envision a world with better oral health for everyone.

Dr. Hirsch is the original inspiration, co-founder and developer of the Isolite family of dental isolation devices from Zyris.
