Have White Tissue Growth Under Upper Lip Inside. What Could It Be?
Fibrotic growth due to Trauma.
Thanks for your query.
I suspect it to be fibrotic growth caused may be due to physical trauma or injury by sharp tooth margin or restoration.
It can even be minor salivary gland swelling or fungal infections like oral candidiasis.
Please visit a dentist and get the examination done as exact diagnosis can be made only after clinical examination and pathological evaluation.
