I just noticed a tiny mole-like dot on the inside of my left cheek, above my wisdom tooth. melanoma? my dad once had a pre-cancerous mole removed.

Likely benign: Pigmented lesions can be seen in the oral cavity. The most common are benign such as melanotic macules, nevi, smoker's melanosis, amalgam and graphite tattoos, racial pigmentation, and vascular blood-related pigments occur with some frequency. If it has been there for a while, it's likely benign. If it is relatively new, then follow up with your dentist/oral surgeon to rule out other causes.

MOLE INSIDE CHEEK: IF IT HAS BEEN THERE FOR SOME TIME, I RECOMMEND THAT YOU SEE A DERMATOLOGIST. HE OR SHE WILL CUT IT OUT, UNDER A LOCAL ANESTHETIC, AND THEN SEND IT FOR PATHOLOGICAL EXAMINATION. BETTER BE SAFE . . . BEST LUCK.
