If they are all straight up and down and in good placement why are you having them removed? The only time I've heard of them being removed is when they come in crooked.
I had to have my upper on the top left removed because the one below it was removed and the top one just kept growing till it was hurting my gum on the lower jaw.
I have the two on the right side.
i also found out that i have big healthy teeth, and the wisdoms are also big, and they are pushing my good teeth around and screwing shiz up, and i have insurance right now for dental so might as well... the desk lady showed me the bill and it was just under 1600 total, for everything, and i only have to pay 180 due to my insureance and the good coverage, so its a good deal in the long run
