we just received our new mouthguard cleaner into stock. it looks like an alka seltzer tablet. Its very easy to use. Once a week you put your mouthguard into some water, drop in a tablet. Let it sit for a bit. The tablet dissolves and totally sanitizes the guard as well as giving it a nice minty taste that lasts a couple of uses. For this month anyone who buys an OPROShield mouthguard from our site will get 1 month's worth of free mouthguard tablets! Any questions you can PM me here or shoot us an email through our contact page.
