OMG!! YOu have to get some. It's the absolute remedy for toothpain - it can be yuck but it's awesome. If you don't have some, try sucking on a clove. This is copied straight from the net, but it'll save you searching:

When you use clove oil for toothache pain, it's the eugenol (an ingredient within clove oil) that provides relief. Eugenol is a natural anesthetic and antibacterial, and it works well at reducing inflammation in the mouth.

basically, it's the GO TO for toothpain babe, honestly, best stuff ever.
