Cue the Zamboni!

The Ontario Hockey League is living out every dental pros' dreams by sending dental offenders to the penalty box. The infraction? Players who chew on or fail to properly use their mouthguards.

In just four days, over twenty 10-minute misconducts have been issued. The league took heat, but pointed out that there are 28 percent fewer concussions among those who wear mouthguards.

Fewer cracked teeth, and healthier heads!
