Wisdom teeth?

I had my wisdom teeth removed on 2-19. I am 37 years old and have endoured the pain for 20 years. The past 8 to 10 years I have felt disconnected, almost light headed. I dismissed it as a side effect to my blood pressure meds. However since I have had my wisdom teeth out the feeling has went away. Although none of them were impacted one of them was decayed some. Is it possible that my wisdom teeth were some how poisoning me? I have done a little online research but have not found any info on this subject...thanksYour teeth can't poison you, but there is a possibility that the tooth may have hit a nerve or something that is causing something in your brain to cause you to be lightheaded.
