Mouth Diseases

Blood bumps in mouth



What is the cause of a circular blood bump that appears on the inside wall of your mouth? It appears randomly and at a time frame of about 4 months since the last occurance.


The most likely condition that this "blood bump" represents is a small bruise (assuming "the inside wall of your mouth" means the lining of your cheek) caused by accidentally biting this area, either while eating or during sleep. These little bruises are common and harmless. It should resolve within a few days. If the "blood bumps" become more numerous and start developing in areas that are not associated with the biting areas of the teeth, then you should be seen by an oral pathologist for further evaluation.
