The swelling in the mouth usually takes few days to subside after hemiglossectomy. Since this a new swelling that you have noticed I would suggest you to schedule an appointment with your treating doctor and get yourself evaluated. Meanwhile please continue with a soft diet for some months to avoid damaging the graft and ensure complete healing of the jaw.
Thank you very much, I have an appointment scheduled for next week. I will continue with the soft food diet as you and my team have advised.
I am glad you found the advice helpful. I wish you all the best for your next clinical examination.
