Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain painless swelling of the gums with a history of
sinus infection that has been treated with antibiotics dos not seems to be due to rinsing of the sinuses with fluid rather it can be due to infection in the gums, side effects of medications if you are taking any,
hormonal imbalances, idiopathic enlargement that is due to unknown cause,
allergic reaction etc..
I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigations like x ray, biopsy,
blood test etc can help in diagnosis and treatment can be done accordingly..
As of now you can do salt water rinses..
Do cool compresses over the gums..
Take a
soft diet to avoid irritation and bleeding..
Drink plenty of water..
Use a soft toothbrush to brush your teeth..
Hope this information helps..
Thanks and regards.
