Jamm,

I just want to mention, or reiterate, that the root canaled pre molar in that quadrant is a source of chronic infection and it does have radio graphic pathology at the apex.... which you may be inaccurately told is scar tissue. Infection, such as this tooth, can prevent healing from any type of surgical intervention you have in that molar area and sinus. This risk includes a less than successful healthy integration of a dental implant if you were to consider that in that molar area sometime in the future.

I just wanted you to be aware of that.
