I've needed my wisdom teeth out now for five years, and recently (this past year) I've been experiencing excruciating pain and headaches, which I know is a result of not having the funds to have them removed.
I have all four, and they are all impacted, which has led to severe crowding and me biting my tongue on more than one painful occassion. Food is always getting in the space between my gums and the crown of the bottom wisdom teeth and I suffer chronic infections.
