It seems like an ulcer formation due to tongue bite from a sharp tooth. Get it evaluated by the dentist to determine the root cause. Rounding off the offending tooth may solve the problem.

Hi, If its not healing on its own within a span of a week you should get a consultation done from a dentist. There might be some irritation factor in the mouth which is not allowing the area to heal. However if its not an ulcer and a nodule a small excisional procedure will do. As the picture is not clear its difficult to make out if its an ulcer or a nodule. Please do refer to a dentist

Hi sir....   This picture shows it  may be Apthous ulcer... Ulcer is break in the continuity of oral epithelium Causes: **stress and anxiety **vitamin B 12 deficiency **viral infection **Iron deficiency anemia **Genetic factors **Gastric disturances(GERD)

Hi! The picture is not clear so can't make out exactly what it is but could be because of some sharp tooth which needs rounding off.

This is normal apthous ulcer u can just apply dologel on the tongue and dont spit for half n hour and dont drink water also at least for half n hour.

Any lesion that persists for more than a month should be checked out. Consult a dentist for a regular dental check up
