Cerezen is revolutionary new medical device used to treat jaw pain and symptoms associated with grinding and clenching – often referred to as Temporomandibular Disorders (TMD). Cerezen refers to two, virtually invisible, custom-made, 3D printed hollow inserts that sit in each ear canal; the nearest access point to the temporomanibular joint.

Benefits of Cerezen devices

Traditional treatment for TMD and associated symptoms is a bite splint. Many patients do not like wearing these as they are cumbersome and can only really be worn at night. Cerezen’s unique in-ear placement means it is non-invasive and discreet enabling it to be worn day and night with no impact on lifestyle. They only need to be removed when swimming, bathing or during contact sports.

They aim to reduce TMD symptoms including: teeth grinding or clenching, jaw joint soreness, pain in the chewing muscles, radiating pain in the face, jaw or neck, aching pain around the ears, limited jaw movement, painful clicking or popping when opening and closing, headaches, migraines and a change in how you bite.

How do Cerezen devices work?

When you open and close your jaw the ear canal also opens and closes. As the ear canal is close to the temporomanibular joint (TMJ), it makes the perfect place to target the source of the symptoms. When the customized Cerezen devices are inserted into the ear canal, they retain the shape of the ear canal in the open jaw position because they are made of a 3D printed rigid material. They actively encourage the jaw to return to an ‘open bite’ position. The result is a reduction in grinding and clenching and the amount of pain you experience.

What is involved?

Treatment starts with a diagnosis of TMD. The options available to you will be discussed at your appointment and if you wish to have the Cerezen appliances the following is involved.

  1. A trained audiologist takes an impression of your inner ears whilst you bite on a plastic sheet
  2. Cerezen devices are made using 3D printing technology and delivered to Sharrow Vale Dental Care within three weeks.
  3. You are shown how to fit the Cerezen appliances and will be given clear instructions to wear the appliance part time initially.
  4. Wear time gradually increases to full day-time wear. After two or three weeks you should be able to wear the appliances full time.

I decided to look into Cerezen after a family member stumbled across an advert for it online - although a little dubious, I was willing to give anything a go to try and ease the discomfort I had been experiencing with my jaw for some time. The consultation was easy going and very informative; the dentist was absolutely wonderful and additionally, it was great to have the opportunity to speak with somebody else at the surgery who had first hand experience of wearing the 'devices' too.

After going through the process of having moulds taken and attending the surgery again for the 'fitting', I remained dubious. Within a matter of days my feelings had changed, I started to feel a little more optimistic - the devices were ever so slightly uncomfortable for a just couple of days however, this was expected and was no significant problem for me - I had suspected beforehand that I would not be able to tolerate them! A gradual increase in the length of time in which I had the devices in place was recommended however, I was confident in exceeding the recommendations and after approximately a week found myself wearing these permanently (other than to shower). It started to feel a little strange without them in fact.

After a couple of weeks I began to notice changes in my jaw - the discomfort was starting to ease, and further improvements noted after just a couple of month with the embarrassing 'clicking' of the jaw reducing also. Approximately nine months later I'm left amazed at the difference these small devices have made! They are discreet, comfortable and easily cleaned.

Being a staff nurse, I am required to use a stethoscope on a daily basis so I was initially concerned that these devices would affect my ability to do so however, was thrilled to learn that they did not - they have had no negative impact upon my daily routines at all. I could not recommend the devices enough to anybody experiencing difficulties with jaw pain; money very well spent.

For as long as I remember I have suffered with pain from my TMJ and my joints tend to click when I eat and speak. I have tried all the options my dentist has suggested including a soft splint and a well-made Michigan hard splint. The hard splint helped significantly – but I cant eat with it in and I cant talk properly with it in – so I couldn’t get on with my day to day business.

I had heard about Cerezen – though I have to admit I was sceptical about it as the company is still to do trials. I was wary because I couldn’t work out how something placed in my ear would help!

Galer asked me to put my little fingers into my ears and to open and close my jaw. I then realised that my jaw joint was so close to the ear canal and may be Cerezen could work and it was certainly worth a try.

Firstly, I saw an audiologist who took my ear impressions. They were taken one at a time whilst I was biting on a large bite block between my front teeth. It was not uncomfortable. Three weeks later the devices were ready to try. I was given advice on how to insert them and instructions on wear time. I very quickly became comfortable with wearing them for the whole day and quickly progressed to night-time wear.

As for my TMD, I can now eat comfortably and do not suffer with jaw pain when I eat and speak. They have certainly improved my day-to-day life and I wouldn’t be without them now.
