I am a 70 year old male and I have a white spot on my bottom lip that wont rub off. What could it be and how do you get rid of it?
With your query, you didn't mention where the white spot is present on outer side or inner side you have mentioned cannot be rubbed but again no history if your adverse habits like smoking, pan chewing and Gurkha etc. Which is mandatory to know hence, I suggest you to visit a specialist dentist in oral medicine without delay. Hope this is informative.
