So I have been lightheaded for over a yr. I have been to every doctor and everything is normal. I found a website where people felt the same way I do and when they had their wisdom teeth removed they felt better. I have 3 wisdom teeth, 2 on the bottom and one on top. They do not hurt me but the one on top is going into my nasal cavity. Could this be causing my light headedness? Should I have them all removed?
