In an effort by the American Dental Association to stop kids from ruining their teeth with candy, they’ve teamed up with PopCap Games to give away free copies of Plants Vs. Zombies instead! I’ve gotta admit, this is a pretty cool promotion.

Head on over to Stop Zombie Mouth to get your free coupons to pass out to the kiddies on Halloween. The website also has wallpapers, coloring pages, and posters about proper brushing and dental hygiene.
