Here's a tip when deciding on which night guard is right for you:

Remember that if you do not wear your night guard for a while your teeth may naturally shift overtime. This can cause your night guard to fit incorrectly. So, if you do not wear a night guard often (consistently), it's probably better to choose the Sentinel Soft Dental Night Guard.

    Grinding was damaging my teeth and I could feel discomfort my incisors waking each morning. Wanting to have my natural teeth for many years to come I ordered this product after doing research on night guards. After receiving the custom fitted piece I was impress how it seated perfectly into place. I’ve ordered two different guards, the first was a lower guard which was a little less comfortable. I read that upper guards for many people are more comfortable so I ordered a second guard fitted for upper teeth.

    The upper guard is very comfortable to wear and I use it every night with absolutely no issues. From the very first use I knew it was protecting my teeth from damage and I no longer have discomfort from grinding. In addition to protecting against grinding I would imagine this guard is perfect to prevent teeth from migrating if one has a missing tooth. Teeth kind of drift if they aren’t opposed on each side. I’ve recommended this protect to friends who have missing teeth to help keep their remaining teeth from drifting over time.

    This is one of the most comfortable night guards I have used. But most importantly is the outstanding customer service! Although an easy process to make the impression, I messed one of these up and Ashley at Sentinel was extremely helpful and sent another out. I ordered two of the harder material night guards, one for me and the other for my wife. After receiving the harder one, my wife preferred the softer material. I contacted Sentinel where they were quick to respond saying one will be made and sent out. So much easier (and less expensive) and convenient doing this at home vs. at the dentist. Highly recommend Sentinel.

    I’m honestly floored by how well the mouthpiece fits right out of the box. I have used grind guards for a few years for bruxism any to alignment, paid roughly $1000 a year and made more trips for adjustments than I could count. After getting this mouth piece, I don’t think I will be getting any more from my dentist.

    Molding was easy, and shipping was quick, even though it was the same time period as two big storms in Florida.

    Will definitely be ordering again!

  • Donna LeGrand

    This the only mouthguard I’ve ever been able to wear. It’s worth every penny.

  • ken

    The fitting process was easy, no issues.
    The guard itself was comfortable.
    I ordered a 3mm on 1-23 and am now ordering a replacement on 8-31 (7 months latter, probably 6 months of actual use).
    I just started getting my “severe ear ache” sore jaw back so that’s my Q I have worn this out. I’m not sure 6 months use for $98 I am really satisfied with but it’s a whole lot better than the cost at the dentist.

    I received my new mouth guard, at first I thought it was too tight. But I continued to were it and it stretched out to a good fit. Satisfied Customer.

    Love that this company lets you choose your own thickness. I have the worst gag reflex and needed a very thin nightguard. I’m pretty sure this is the only online company that offers the thickness choices. Happy customer!

  • Billie Jo

    Didn’t realize I would have to make a mold and send it back in to the company but am excited to see how it works. Kit seriously came within 2 days. Eagerly awaiting the final product to come back. Excellent company to work with!!!

  • Carol A. Havelka

    Excellent mouthguard. Does not bother me at night or slip out. Actually fits better than one I had made my dentist. Will definitely buy from Sentinel again.

  • Gabriel Montahue

    Ive had my mouthguard for about a year and a half now. Just had to use my warranty to get it replaced. Felt inclined to leave a review about my experience.
    Sentinel Mouthguard Co. stands by their replacement warranty. No questions asked, I simply attached a picture of my nightguard showing existing wear to an email to the company. Within 10 days I had my replacement. I don’t know of any dental office that has a warranty like this. Exceptional customer service & product. Thank you Sentinel.
