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 shouldnt I be on a antibiotic in case I have some infection going on?
Hello, Thanks for writing to us. The sores on tongue as well as on cheeks can be due to sharp edges of tooth. Please do visit a dentist and get the sharp edges of teeth smoothened. Apply anesthetic gel on the affected area. Avoid spicy foods. Maintain oral hygiene well. Take complete course of antibiotics too. Take care.
