Can any doc explain why are my gums getting bigger and how to cut them back?

No: But a doc that actually sees you for an exam can probably help by first figuring out what is going on then providing or referring you for appropriate treatment. This is a common side effect of certain medications or it could be evidence of underlying disease or it could just be a variation of normal. You really need to be seen to get a meaningful answer.

See dentist: Swelling gums, bigger gums can be a sign that you are at risk for, or already have, gum disease. The bacteria and other particles, constantly form a sticky, colorless toxic “plaque” on teeth causing the gums to become inflamed and to easily bleed. This is a serious problem, which should be checked by a dentist. The good news is that this condition is curable. Call your dentist today!

Several causes: The gingiva or gum tissue usually follows the anatomy of the teeth and supporting bone structure. Enlargement of the gum tissue can be related to periodontal problems, additional bone growth (exostosis), as well as from side effects from different medications. Treatment will be dependent upon the cause and would be best answered after your dentist evaluates you and your medical history.
