Tongue and mouth: When you start to look closely at the body, things might seem strange or weird. The mouth has alot of structures in it that can look very bizarre if you stare too long. Good you showed this to a doc -I would trust that opinion. You can show Health Tap docs too by uploading a pic. Probably this is just a mucous film -try drinking more fluids. I like to 'rinse' throughout the day -helps the breath 2
