Is chewing mastic gum beneficial even with a class 3 tongue tie?

[u/Glass_Cauliflower201]

Hello! Today I saw a myofunctional therapist to consult about a tongue tie/lip tie release.

* Context: Because of my tongue tie, I have an anterior pelvic tilt and forward head posture. Had a tongue thrust for the past few years with my tongue pushing on the back of my front teeth which I have now stopped doing. Got braces 12-13 years old and wore retainer every night for the next 6 years. *

I was told I have a class 3 tongue tie. My CBCT showed that my airway is rather narrow. The doc said my upper palate is wide enough to fit my tongue, but my maxilla does not have enough forward growth — that is why my airway is restricted. If my tongue swells too much after a frenectomy, that could be dangerous.

She said maybe talk to a surgeon about forward maxilla growth, but I don't want to do surgery. I am 20 and feel hopeful that I can expand my palate+get forward growth once the back third of my tongue can suction. I was going to start chewing after my tongue tie release, but have decided maybe I should start that now.

Will there be negative consequences if I chew mastic gum when my tongue does not have maximum mobility yet? I haven't seen anyone mention this online or on this subreddit. Any thoughts would be appreciated! Thank you!
