<s>[INST] Hey, just last night i realized this grey almost rotten mold area in my high upper gum. I actually picked at it a little just now and its a hard grey looking growth, i was able to move it and actually take a side of it out but it seemed like it extended into my gum a little further so i didn t risk pulling the entire thing out and i dont currently have tweezers. Any idea what it could be? Its really freaking me out and I m probably going to call a dentist tomorrow. [/INST] Hello and welcome, is your teeth decayed?or the gum is grown into the decayed area. Then it may be pulp polyp or gingival polyp. Pulp polyp is a unique form of pulpits wherein the inflamed pulp, instead of perishing by continued suppuration, reacts by excessive and exuberant proliferation.it involves teeth with large, open carious lesions.a pulp so affected appears as a pinkish-red globule of tissue protruding from the pulp chamber and not only fills the carries defect but also extends beyond. The lesion may or may not bleed readily, depending upon the degree of vascularity of the tissue and epithelialization. The involved tooth have an excessive blood supply because of large root opening. This may persist as such for many months or several days. The condition is not reversible and may be treated by extraction of the tooth or by pulp extirpation. Regards Chat Doctor.  </s>
