Hie.. yea u need to visit the dentist for your replacement of the lost teeth.. get your treatment completed at the earliest ..

Hi. I hope the dentist had done thorough clinical investigation of the trauma site. Which injection was given? You need to visit a dentist again: 1) To rule out any other injury except for the loss of tooth, 2) For clinical and x-ray evaluation, 3) To consider for replacement of the lost tooth as those were permanent tooth and no other tooth will erupt in that place.
