my son is 16 and his tongue is large and does not look normal. I have been trying to look up sublingual papilla, that is the part of his mouth that lis huge. He looks like a bull frog. He says it does not hurt. I have to wait to see the doctor and I am getting nervous.
With your query, nothing to get nervous in some individuals tongue will be little bigger than normal technically termed as macroglossia. Only problem with this situation is it may cause disharmony or misalignment between the teeth, but your son is completely asymptomatic so nothing to worry about it if you are tensed you can get an advice or suggestion from your dentist and general physician as well. Hope this helps you.
