About Cerezen

Cerezen is a unique, pioneering medical device that effectively treats TMD (Temporomandibular Disorders) and associated symptoms such as Jaw Pain, facial pain and tension headaches.

Clinically effective , and custom made to fit your ears, Cerezen devices can be worn day or night. They’re discreet and comfortable because they’re specially-made for you.

These conditions are often collectively known as Temporomandibular Disorders or TMD.

The two custom-made, 3D printed hollow inserts sit comfortably in each ear canal; the nearest access point to the temporomandibular joint.

The Science Behind Cerezen

When you move your jaw, your ear canal opens and closes. As the ear canal is so close to the temporomandibular joint (TMJ), it makes it the perfect place to target the source of your symptoms.

When your customised Cerezen devices are inserted into the ear canal, they retain the shape of your ear canal in the open jaw position because they are made from a 3D printed rigid material.

The Cerezen devices effectively encourage the jaw to return to a relaxed position and provides symptom relief.

Choose Cerezen

“The concern with a bite splint is that we’re not actually telling our patients to stop biting, we’re just saying they can bite down on this and they’re not going to cause any damage to their teeth. What I would like to do, is to prevent my patients from doing it in the first place. That’s why Cerezen is unique and really effective – because we’re stopping the source of the problem.”
