Despite this, the overall experience was great, and I encourage others to try molding before judging the size."

There's no need for molding; he can just pop it in and get started!"

"I have a small mouth, and I found this mouthguard to be a bit too big for me. I couldn't help but laugh when I started drooling shortly after putting it on.
