Why a custom made mouth guard?

When A Mouthguard Is Super Comfortable, It’s More Likely To Be Worn

We know that a lot of people avoid wearing mouthguards because they’re uncomfortable. They get in the way of speech, and sometimes hamper breathing. They can also put stress on ones jaw if it doesn’t fit right.

The Difference Between Our Mouthguard For Teeth Grinding & Our Athletic Mouthguard

A mouth guard for teeth grinding does not need to extend all the way up to the gum line. Rather, the Sentinel night mouthguard hugs all occlusal (chewing) surfaces and extends approximately 1-2mm up the facial and lingual surfaces of the teeth. The dental night mouthguard is about 30% denser than the athletic thermoforming material. It is also not as bulky as the Sentinel athletic mouth guard.  The athletic mouth guard is made of a soft, shock absorbing plastic and the night guard for teeth grinding is made of either a hard acrylic material, a soft clear material or both (depending on which model you choose)!

What Are The Experts Saying?

The American Dental Association promotes the importance of safety in maintaining oral health and the use of a properly fitted mouthguard as the best available protective device for reducing the incidence and severity of sports-related dental injuries.” -source ADA (American Dental Association)

Custom Mouthguards Are Different





Your Most Common Questions Answered.

Q:What is the difference between a properly made mouthguard (or night guard) and a store bought one?

A: It is custom made for you; the custom-fit mouthguard is made from a mold of your teeth using the best quality material. With store bought mouthguards (specifically boil and bite guards) the sizing is limited, and any modification can jeopardize protection. Most importantly, you can lose up to 70% of the protection after the boil and bite process.

Q: Do you sell stock mouth guards (or night guards), what kind?

A: We do not. Professionally fitted mouthguards are the absolute best guard that money can buy. All other mouth guard types are subpar to true custom guards. Over the counter or “stock” mouth guards (whether its for teeth grinding or for sports) will not offer complete safety for your teeth. Also, the majority of people tend to find these types unable to use comfortably. In regard to athletic mouth pieces, to maximize protection of your teeth, you will need to use the custom fit mouthguard because you can lose up to 70% of the protection if you use the boil and bite mouthguard. Stock guards (cheap, unfitted guards) offer little protection & are in danger of falling out or getting knocked out easily.

Q: How long will it take to get my custom mouthguard?

A: For athletic mouth guards-upon receipt of your impression, approximately 5-10 business days depending on complexity of mouth guard design.

For custom night guards- upon receipt of your impression, approximately 3-7 business days.

Q: How does the custom mouthguard fit?

A: Looking for the best mouth guard? This is it. All Sentinel custom-fit guards (nighttime or athletic) are individually made from the impressions of your teeth. Follow the directions correctly, and your mouthguard will be snug and comfortable. A good impression should include all your teeth and extend to the gum tissue above the teeth.

Q: How long will my mouthguard last?

A: Stored properly in its case and cleaned regularly, your guard should last 2+ years. Keep in mind that the Sentinel warranty and return policy is unlike any other. We stand by our products and will always work with you to your absolute satisfaction. This means that if you are dissatisfied with your product for any reason, you can either contact Sentinel within 14 days for a full refund or opt to continue working with us until you get a great fitting guard. Our commitment to you is 100% satisfaction.
