White spots on the lip may be mild skin irritation, a fungal or viral infection. I suggest that you avoid drinking hot beverages and prolonged sun exposure. Other possible causes for white spots on the lips may be cold sores which is due to herpes simplex type 1 virus. These spots however are painful and they may be associated with a burning sensation.
Continue to observe the spot. This should resolve spontaneously. Avoid direct skin to skin contact since if this is a viral infection this may be transmitted through direct skin to skin contact.
