Defending Your Smile Starts Here

Teeth grinding and clenching cause headaches, jaw pain, and teeth sensitivity. Additionally, teeth wear, cracks, chips and breakage are all common side effects. We understand the short and long-term effects of teeth grinding and clenching. Teeth wear, cracks, chips and sensitivity don’t just happen overnight but once it happens, costly dental work is needed.

Ask any dentist-there is nothing better than natural, healthy teeth. With Sentinel Mouthguards, your teeth are comfortably protected and your tooth structure stays preserved.

Product Reviews

  • Jean R.

    I received a very expensive night guard from my dentist and it was so bulky I couldn’t close my mouth let alone sleep with it in! I called Sentinel customer service, spoke with a very nice lady and she suggested this guard type. I went with the “thicker” option and was assured that it would not be bulky. She was right! It’s perfect for my mouth. It protects my teeth well and my jaw says THANK YOU!

    For the impression process, I received a kit in the mail quickly after ordering. It came with an extra set of putty and I didn end up needing it bc my first impression was too shallow in the back teeth. I sent a picture in and again the communication was fast. The reply email stated the reason why it wouldn’t be acceptable and came with a reference picture of a great teeth impression plus additional tips. I retook my impression and it came out much better the second time around.

    The shipping of the night guard was quick. I received an email when it shipped and it didn’t take the lab long to make it at all. The night guard is flexible and clear. It appears to be high quality material and has felt comfortable in my mouth right from the beginning. My experience has been great and I recommend this company without hesitation. A+++
