I recently lost a tooth which I have to have the rest of it removed on Monday. I also lost a crown which left not much tooth there to re-apply it so that tooth also has to be removed. I wear a flipper and have been noticing my tongue catching on a rough spot for a few weeks. My tongue has a sore spot now and is red in that area and a white bump in the center of it... I told my dentist this but he has ordered a tongue biopsy evaluation. The tip of my tongue also seems numb at times. Could the jagged edge of these two left teeth be doing this to me also? Since then I have noticed another lump in my cheek also where my teeth have bothered and my mouth seems irritated now and hurts. I have been gargaling with salt water which seems to help. But shouldn't I be on a antibiotic in case I have some infection going on?
