It's one thing to have LEDs around the house or even on the head, but in your mouth? Um, no.

The "Ionic Teeth Whitener" promises to keep your pearly whites sparkling with a special blue LED that that "activates silver ions" in its accompanying toothpaste, according to Red Ferret. For $30, it promises to "remove stains from coffee, soda, wine, smoking and more."

More? If you've got more issues than these, you probably need more than a dental cleaner in your life.
