Cerezen™ at O’Neill Dental Care

Our lovely patient Louise decided to try Cerezen™, as she was experiencing daily pain and discomfort – and she was thrilled with the results of her treatment!

Read about Louise’s journey below:   

I have had a lifelong problem with clenching and grinding my teeth. This caused me head, neck and shoulder pain. The discomfort was constant and worst in my temples, base of my skull and neck.

I tried different splints. I chewed through one and another was unbearably uncomfortable. The wear and tear on my teeth continued. I lost enamel and feared I would eventually lose my teeth.

However, I then read about cerezen when researching solutions online. It was described as a pair of custom made ear inserts, which prompt the jaw to stay in an open bite position. I was intrigued. Mainly because this approach was different. It wouldn’t just splint the clenching action. It would break the cycle, meaning that clenching would no longer occur.

I decided I would go for a consultation with O’Neill Dental in Swords, as they were offering the best price. 


The dentist explained everything and I decided to go ahead with the treatment. I was referred to an audiologist who made impressions of my ear canals.These were then used to 3D print the cerezen inserts. As soon as I tried them, I knew they were going to work for me. The dentist showed me how to insert them. I couldn’t wait to start experiencing life without clenching.

I wear them every night, the cycle of clenching has been broken. My head, neck and shoulders are no longer tense and muscles no longer knotted.

All these symptoms I had been used to living with are gone. I’m so relieved my teeth are no longer in danger of being worn away completely. My quality of sleep and life are better.

I’m really pleased with my decision to get cerezen. I would recommend them. I consider them an investment in my health.
