Say: nite gard
Nope, these aren't people who protect you when it gets dark! We're talking about the night guards that protect teeth. Night guards are made of plastic and are like the mouth guards that football players use. You wear one when you sleep to keep you from grinding your teeth. If you grind your teeth too much, your teeth can wear down.
