I was certainly skeptical especially buying something from ad

I was certainly skeptical especially buying something from ad, but this one I am counting as a divine gift from above! Not only has the customer service response been stellar, but literally the first night of wearing the device gave me so much relief. I'm only on the 3rd night now as I write this, and it gets better each day. the muscles in my entire jaw AND back of my neck into the sides of my neck have relaxed so much.. I truly feeling like I'm being rehabilitated,. Even throughout the day, I am creating new healthy muscle memory instead of the constant battle of tension and pain forcing myself to relax. I am able to just gently remind my jaw/chin to fall into correct position and it's working! I will be sharing this with anyone I know that have these issues!! Thank you to the creators of this amazing product and your excellent service. Truly life changing...

Conclusive review in progress...

Arrival was quick! The setting up of the mouthpiece was unnerving although fairly easy by following exactly what the instructions says. I've used the mouthpiece two nights in a row and it is definitely taking some time getting used to it. It makes me more hyperaware on whether I'm clenching my jaw so it does somewhat wakes me up a bit. I do have TMJ, although minor and I experience no pain, the mouthpiece does exacerbate the symptom more. I would no recommend the mouthpiece for people who suffer from jaw pain as it may make your symptoms worse. Other than some stiff jaw in the morning afteruse, I will continue to use it and check back in a month or two with my progress.

This is the only mouth guard that has ever worked for me

This is the only mouth guard that has ever worked for me. If you’re on the fence about it, do it. You won’t be sorry.

ClenchRelief holds my jaw in a position that makes me feel relaxed and comfortable

ClenchRelief holds my jaw in a position that makes me feel relaxed and comfortable. It is custom fit to my mouth. My jaw pain is much better since I started using it. I’m so glad I got it. The entire process was smooth and easy and very convenient, completely online.
