wow, you sound like you are holding a lot of anger and resentment, one of the 2 emotions the liver is responsible for when it's unbalanced!
i would try clove oil on the infected or painful tooth and just go ahead with the liver cleanse. it sounds like you are gonna explode with frustration and the cleans will release the toxins plus the emotions associated with them. no point to hold it in any longer...you've come to the right place!
don't be discouraged to do the liver cleanse by the sequence of cleanses. i don't think the specific order of any of these cleanses are 100% critical - you will find both positive and negative feedback from doing the liver cleanse first...just read some of the posts. they vary.
good luck and don't be discouraged. this will all pass. take control of your health however the attitudes and the greed of the medical system you can't change.
