Hi, thanks for sharing your health concern with team HCM!
In the present case of a gum swellings or lumps just behind the teeth, if I were your consulting physician, I would just consider 3 possibilities like:
1. a papilloma-like benign squamous epithelial benign fibro-epithelial polyp
2. infection or some peri-odontal or peri-
apical abscess or a pyogenic granuloma
3. benign cysts like peri-apical cyst or mucus retention cyst!
As per your description, I would like to advise you to maintain
oral hygiene and do a microscopic examination like FNAC from the nodule to confirm its character and relieve your tension!
Take caution not to get injured there as this might invite infection.
Hope you got your answer. Please feel free to write to us if any more queries or with the reports / follow-up...
Wishing you the best health!
