you may have a parasite living in the root of your "dead tooth". i have two teeth thaat were rendered "dead" by some form of head trauma and i found to my horror that a parasite had taken up residence there after i started the parasite cleanse. i wouldn't have even known it if i hadn't read somewhere( i wish i could remember where)that these pests can and do live in the roots of "dead teeth" i.e. root canal. so if this is true in your case, you might have stirred it or them up by taking the Clarkia . as heyjude sez, put some Clarkia on a q-tip and dab it on the afflicted area a couple of times a day and keep up the para-cleanses. let me know how it goes with you and i'll do the same. right now alot is happening with my teeth but i think i'm finally winning. keep up the faith. icky
