2 months ago had abscessed tooth removed. No problem till a week ago when a shard of the tooth started emerging from the gum which became tender and started aching. Dentist was going to remove it when doing preparation work for a bridge, but didn't. Pain has been increasing and dentist has refused to do anything until the bridge is ready to be put on when he will file the protruding bit off. Meantime I have put myself on amoxillin to stop the pain. My question is should I ask to have the piece or pieces cleaned out before the bridge is fixed on next wednesday or just trust that 'everything will be alright'?
