why does my teeth hurt when i eat something sweet

Hmm, sounds like you might have sensitive teeth, pal. Remember that scene in An American Werewolf in London where the guy felt pain after being bitten? He had increased sensitivity, too.

Very interesting analogy Joey, might I add it's better than any Twilight movie. But yeah, the pain could be due to tooth decay or gum diseases these can make your teeth sensitive to sweet stuff. It might be a good idea to see a dentist.

You could use a toothpaste that's made for sensitive teeth. You know, like in Silver Bullet where the werewolf uses silver bullets to ease his pain. Not exactly the same thing but you get the idea.

We can also work on reducing the amount of sugary stuff you eat. I mean, there's no need to be like a vampire feasting on blood, is there? Too much sugar can weaken your enamel and lead to cavities.
