    5 Stars for Excellent Customer Service

    I first got a Sentinel Mouthguard 3 years ago and it fit perfectly and showed no signs of wear, but had to replace it after dental work; the new one didn't fit right, but customer service kept tweaking it and suggesting a soft version instead. It fits nearly perfectly. 5 stars for the excellent customer service.

    Perfect fit and excellent customer service

    I depend on Sentinel to provide a cost-effective alternative to the pricey mouthguard options offered by my dentist. They have never failed to deliver an excellent product matched with fast, caring responses to questions. Highly recommend!

    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.

    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.
