Does any of this apply?
Book an appointment
Arrange a routine dental or medical appointment if you notice a persistent lump or swelling in the jaw, unexplained loose teeth, a lasting change in your bite, or numbness of the lower lip or chin.
These symptoms have several possible causes, but they should not be ignored.
Continue scheduled follow-up even when you feel well.
The article also says
If you have already been treated for an ameloblastoma, contact your treatment team about a new lump, increasing jaw fullness, changing sensation or movement of teeth.
Every sign above is quoted from the sofidex article on Mandibular ameloblastoma. If you are not sure, err upward — it is always reasonable to be checked.
