As you said only the crown portion was removed, that means its removal intotal would involve a bigger surgical procedure. So be ready for reopening, jaw bone removal and stitches before going for the same. My advice is to wait and watch and get further treatment only in trouble. We have seen a few of the patients who suffer from pain
unless whole of the tooth portion is removed, but at the same time we have experienced uncountable number of our patients and the ones who were treated elsewhere, who did not have any problems in the same situation. Anyways do have the medicines if suggested.
