    Soft Dental GuardsUpper & Lower Guards for Tongue Biting

    $189.00 $159.00

    Product description

    The Sentinel soft dental guards for tongue biting were designed for comfort, ease of wear and effective protection from the damages that result from tongue biting during the night or day. Our high polishing system and thin design ensures a supreme fit. Your upper and lower guards are to be worn at night or during the day to protect your tongue from damages associated with nocturnal/nighttime or daytime tongue biting. The soft padding on both the upper and lower teeth prohibits direct tooth to tongue contact thus preventing damage. Taking your own dental impression is EASY (and you do not need to pay a dentist hundreds of dollars to do it). We will send you a plastic tray, dental putty, & a pre-paid envelope to mail back to us. You need to have a timer, clean hands, & good solid teeth. No braces. Seriously, putty & braces do not mix. We will give you a link to a video, pictures & written instructions to show how to mold, and make sure its a good mold. All inclusive free shipping. Here’s how it works: We mail out an impression kit to you (mixing putty & a tray). You take your own impression & using the pre-paid envelope, mail it back to us. Upon receipt of your impression, we will fabricate your new custom fit night guard within 8-12 business days. That’s it!

    Many people search the internet daily in hopes of finding a product that will protect their tongue or cheeks from damage associated with tongue and/or cheek biting. The Sentinel Soft Dental Guards are made to fit your teeth like a glove. The soft padding disallows the chewing surfaces of the teeth to catch the tongue or cheek area. The product will prevent any trauma to the tongue or cheek area and will allow any previous trauma to heal.

    Want to reorder your custom dental guards for tongue biting?

    We keep all dental impressions on file for two years from the purchase date. As long as  your dental anatomy has not changed, we can make you a replacement set of upper and lower dental guards at a 20% discount. The coupon code to apply if you already have your stone molds on file with us is alreadyhavestone

    Not only does the powerful ZOOM! whitening gel give stellar first time results, the Sentinel upper & lower custom made reusable teeth whitening trays are the solution you've been looking for to keep your teeth consistently white. When we compare custom fit trays that are made specifically for you to other forms of teeth whitening(white strips, white lightening, mall kiosks, etc) one can quickly see the short term and long term advantages of using the custom fit trays. You cannot get a more comfortable fit than thin clear trays that are made specific to your exact dental anatomy. Many wear these trays while they’re at work interacting with clients & co-workers because they’re so unobtrusive & unnoticeable. Unlike most teeth whitening methods that are only good for one treatment, your custom trays can be used and reused for years. When you run out of gel, simply order more! Your teeth will stay white year after year. The Sentinel Teeth Whitening System truly does give you the biggest “bang for your buck”.
