Hello!
Behind my wisdom tooth, a small bump has appeared on the gum, similar to a fibroma or wart, the colour of the gum, about 2–4 mm in size and painless. Is it possible that it will disappear on its own over time, or is surgical removal necessary?
Thank you for your answer and kind regards.

Dear Sir/Madam!

Whether this really is a benign tumour, namely a fibroma, can only be confirmed by histological diagnosis. Until then we can only speak of a formation resembling a small, firm swelling. Similar formations are not dangerous and are removed if their presence causes problems. A fibroma is also a completely harmless formation. I cannot tell you whether the formation will disappear on its own.

Have a nice day!
