Hello Kajal, thank you for commenting and I am sorry to learn that you have ongoing symptoms. I am not a doctor, but a medical journalist who also has acromegaly.  For sure, pronounced under- or overbite, spreading teeth, and enlarging tongue are typical symptoms of acromegaly.

I have read about surgery to correct under/overbite and even an enlarged tongue, but I think you would need to seek out the opinion of a true expert and personally I would not consider such surgery until the acromegaly was consistently under control long-term.  Good luck and best wishes.
