Strangely I have been attending many dentists regarding my teeth over some time pain along the side of tongue. The dentist I saw to day wants me to go directly for a biopsy at the Dental hospital.  Pain also under inside of jaw and down the throat, painful to drink or eat all on the right side.  Many years ago injured my face and jaw in a fall the upper right tooth broke I think I swallowed it.  I think  all of these symptoms  caused by my tongue being ripped off my worn down teeth.  The white craters are under the right side of tongue, I have been complaining of this for ages but it is impossible for me to see.  My neck is also affected
Dear friend. Thanks for sharing your concern.  Your history suggests that you have white craters under the right side of tongue, that could be due to many reasons like sharp edges of surrounding teeth, oral candida infection due to poor oral hygiene, any malignancy. It is nice that your dentist has advised for biopsy, just wait for its results. Meanwhile get your sharp-edged teeth well grounded, so that further damage can be prevented. Use chlorhexidine mouthwash for 15 days to prevent further infection. Hope it helps. Thanks.take care.
