From your experience, would you guys recommend single or double mouthguards? and what brand would you recommend?
I have heard that doubles are harder to breathe out of, and make some people gag, but they protect your lower teeth as well! Maybe prevent something like what happened in the Parisyan-Sanchez fight.
The doubles have an breathing slot in the middle to allow breathing, but is that enough?
I know custom mouthguards from your dentist are the best ones, but I just don't have $100 to spend on a mouthguard right now.
