one of the best and most durable mouth guards that i have bought [SEP] one of the best and most durable mouth guards that i have bought i have tried many of them since having my new bridge put in and i use them so i do not grind my teeth at night most of the others that i have tried split or grind down or fall apart and i have had this one for months and none of what has happened with the others has happened and the fact that you get for what i paid for one is even better you get for the price of one and they last way longer than the expensive ones
