Happy Repeat Customer

I have severe bruxism and unfortunately cracked the heavy duty night guard I got from my dentist. Because I cannot sleep without my night guard, I had to get a replacement in a hurry. I’ve ordered three guards from Sentinel over the years and have always been impressed with the customer service and quality so I knew that I could get a high quality replacement that is reasonably priced and would arrive quickly. The appliance fits perfectly and is very durable. Would definitely purchase again!

The best. Recommend 100%

Very comfortable, use it every day and sometimes during the day. Easy and for a fraction of the cost! Very happy.

Durability Mouth Guard for Severe Teeth Grinding & Clenching

Durability Mouth Guard

I've had two mouth guards from Sentinel and they've been fantastic. They're thicker than the mouth guard I had gotten from my dentist which I cracked within two months and cost me twice as much. My first Sentinel durability mouth guard lasted almost two years before my severe bruxism cracked it. My new one is going strong; it’s thick enough to protect my teeth and just as easy to sleep in as a standard mouth guard. And the customer service has been so helpful and courteous every time I've needed help.

The mouth guard for severe teeth grinding is great. However, as of to ate I have not received the upper mouth guard. I ordered it the same time as the lower guard.

It's been 5 years and I still use it nightly!

I ordered this more than 5 years ago and my mouthguard is now clearly scratched with bite marks, but still holding up beautifully. This was an exceptional product that I would definitely order again (but so far haven't needed to!)

Not too large, fits great, customer service was excellent!

Great Fit

Great Fit and Great Durability!
