DOUBLE mouthguard vs SINGLE mouthguard

Single mouthguard:

• Feels like your mouth can close tighter.
• Simpler, slightly less hassle to put on and off.
• Doesn't collect as much saliva.
• Easier to breathe.
• Easier to talk or sip water.
• Lets you open your mouth without the mouthguard slipping off.
• Cheaper
• Less coverage than double.

 

Double mouthguard (my personal preference):

• Secures both upper and lower jaw together.
• More teeth coverage (covers the bottom row as well as the top).
• Absolutely needed if you have braces.
• Harder to breathe (for some).
• Feels like you have to always bite down on it, or else it falls out. Some considered this a "PRO".
• Harder to talk and sip water.
• More expensive.
• May cause more saliva.
