Toothache From Hell

I have never had the best of teeth. Not because I didn't take care of them but because it's a genetic disorder that basically causes your teeth to decay from the inside out. Nothing that Im proud of but hey stuff happens. on top of everything going on I have a toothache from hell. It started about two days ago. Nothing I do eases the pain.  It's the pain you get when you have an abcessed tooth. Yes, it hurts. The one thing I haven't tried is a dear friend of mine suggested I use clove oil. Needless to say our local Walmart was out. 

Any suggestions?
