Painful and strange

So first of all, I think the idea is really good to be able to adapt a mouthguard on my teeth.
In the adaptation process the specified time has not fully passed on in order not to leave anything in my teeth, anyway, I had a strange taste in the mouth and a piece of material between my teeth.

However, this was nothing unexpected. Instead, I had to realize that the mouthguard forward as far projecting that it can quickly lead to injuries of the upper lip with a slap in the face.
My coach knew the problem and recommended to buy any expensive unit Mouthguard me.

My conclusion: can quickly lead to serious injury, the price is clearly not worth it!
