    Great product, excellent service

    I couldn’t be happier with my new mouth guard. My dentist was impressed as well. Thanks Sentinel

    Much better than boil and bite -was concerned with microplastics

    Light, tough and can talk with it. Much less and more durable plastics so most likely less microplastics to ingest.

    Mouth guard

    I am impressed at the customer service of this company. I lost my mouth guard and they made a new one, and I had it in less than a week. The guard fits perfectly. I have not had a single issue regarding my no show mouth guard.

    Custom Soft Night Guard

    2nd one works excellently

    fit is weird every evening and fine in the morning. I think my teeth shift a bit and I can't blame the nite guard for this.

    Nice

    I love that it's soft so as to cushion & no irritation to sensitive mouth. Highly recommend.

    Don't Pay More...

    My dentist was going to charge me $250 out of pocket for a guard, not including whatever they charged insurance AND it would have taken 3-4 weeks. This was a great solution, an easy process, and a fraction of the cost. Very happy!

    Best I have used

    I have used other mouth guards in the past but these have been the best and the customer service excellent. It took three tries and quite a wait to get them ( due to my mouth shape ) but it was well worth the waiting. Customer service was great in guiding me. I will continue to use Sentinel mouthguards in the future for sure.
