Stop Grinding!

I have struggled for my entire 77 years with grinding my teeth at night while I sleep. This DenTek Ultimate Dental Guard specifically for Nighttime Teeth Grinding is the way to go. For years the only products that were available were designed for one's full upper teeth bite. They were bulky and I often found them next to my pillow on my mattress in the morning, not knowing how long I had kept it in my mouth. This Guard goes in easily at night, and when I wake up it is still in my mouth. I could actually KNOW it was doing it's job. At 77 years old I am so glad I have finally found a product that works, that lasts, and is available at a good price. The directions on how to prepare the Guard for comfortable wearing are clear and easy to follow. For Night Teeth Grinding, for me there is no other way to go than DenTeck Ultimate Guard for Nighttime Teeth Grinding! Wish I have found it sooner! You will not be disappointed. This is not a DenTeck guarentee, it is my guarentee and I have 77 years of searching for a product just like this, for a problem just like mine.

Ultimate mouthguard

The Den Tech ultimate guard for nighttime teeth grounding is well worth the money. It is easy to use and easy to mold to your mouth. It stopped my teeth grinding on the very first night. It's a comfortable fit, and it does not bother your mouth or tongue. It is so much cheaper than other brands, I would highly recommend this mouthguard for anybody who grinds their teeth at night.

Would not recommend

Followed direction %26 had to repeat after not working the first time. Fit was barely sufficient to use during day, would not trust for nighttime.
