Tooth#18 occlusion needs to be adjusted optimally,otherwise tooth
#19 would be very difficult to achieve optimal occlusion.
Removal of tooth
is advised. Leave tooth #19 out of occlusion for a week.If tooth #19 is still problematic, other sources of dental pain need to be investigated.
Occlusion certainly plays an important role in the pathogenesis of many mysterious pain, but not always the sole factor. I believe your prosthodontist is competent enough to manage your occlusal problem.
