My baby has purple spot on his tongue what could it be?

A few things: It could be a blood vessel, a small blood clot, benign blood growth or something else. Have your pediatrician or pedodontist take a look at it so you will know exactly what it is.

Purple spot: Purple spot cannot be diagnosed without examination. Most probable causes are trauma (biting tongue) or hemangioma, but there are many other possibilities. Please make an appointment with a Pediatric Dental Specialist, a Pedodontist, for an examination.
