My friend cut the side of her gums where they extracted a tooth for a bridge a couple of months ago.  A white spot appeared.  The gums are not sore or sensitive.  When pressure is put on it, a fluid comes out.  The fluid is a very chalky white with consistency of paint.  The spot comes back in minutes.  The fluid does not appear to be a bodily fluid.  She is set to go to the dentist to show him, next week, but curiosity is getting the best of her.  It is definitely not a gum "pimple".  Thoughts?
Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint it seems that a white spot over the gums along with white chalky discharge seems to be a pus filled lump that can be due to infection over the gums in the area while can also be due to any left over root piece after tooth extraction that is flaring up and the infection is causing formation of pus filled lump. I would suggest you to consult an Oral Physician and get evaluated, and he can do a clinical examination and also advise investigations like x-ray for confirmation of cause and treatment can be done accordingly. She can be advised a course of antibiotics like Augmenting and anti-inflammatory painkillers like Ibuprofen. As of now doing warm saline gargles, Betadine mouthwash gargles and maintaining a good oral hygiene can help. Hope this information helps. Thanks and regards. Chat Doctor.
