I had a tooth extracted (upper left hand side midway back) on Thursday 6th March at my emergency dentist service. since having the tooth removed all seemed to be going well however over the past 3 days I have noticed a growing pain in the lower half of my jaw. The tooth that was extracted was actually a shard and some remains as the tooth had broken some time ago, but the shard had become loose and was causing some discomfort (I know that I should have had this seen to some time ago). the pain spreading to my tongue and along what feels to be the lower roots of the teeth and my jaw. The actual area where the tooth was extracted feels quite pain free most o the day however, I have found it extremely difficult eating on that let side of my mouth for both sets of teeth hurting. This pain is also causing quite severe headaches and seems to hurt more when I lay down.
