Halloween is not good for the teeth of trick-or-treaters. There's a plethora of candy, and kids will eat candy they wouldn't normally eat, because hey, it's there. What's a parent to do? Offer cash for candy, with the help of a local dentist. Halloween Candy Buyback, complete with zip-code dentist search, the website for the movement that has expanded from it's quiet start in 2005 with a single dentist in Wisconsin. Now, thousands of dentists across the U.S. buy back tons of candy at a dollar a pound, then send the candy with toothbrushes and toothpaste to Operation Gratitude to be added into care packages for active U.S. Military. If you're having trouble getting a younger child to part with their candy, there's the Switch Witch, who will take a pile of candy and switch it for a special switch gift. And if you want to start at the source, you can always make your own candy with one of the various sugar substitutes, or go with a teal pumpkin and avoid the candy all-together.
