Hi, I have an infected root canal tooth(molar) with jaw involvement that will be removed next week. The surgeon gave me the option of having cadaver bone graft placed for an x-tra $500. He left it up to me and didn't recommend one way or the other what I do. Do I need to do this, will it heal better? I do have ms/lyme so am concerned putting a foreign substance inn there might set things off. He didn't know about that aspect of it.

thanks
