You should keep few things very clear in your mind i.e the symptoms you told are of course related to your impacted teeth , secondly the continuous pressure from impacted tooth will resolve (damage) the roots of your adjacent tooth as well. Thirdly, the only permanent treatment is to go for extraction of impacted tooth asap. I hope this answer your questions.
