What kind of doctor do you see for leukoplakia?

Oral Surgeon. Unless you are referring to the mucosal surfaces of the urinary tract or genitals (then a urologist or gyn) leukoplakia is merely a descriptive clinical term- not a truly diagnostic term - meaning white patch. The causes of leukoplakia are numerous and range from benign and irritation-type issues, all the way to malignancy. Best to have this examined and evaluated to see if it warrants a biopsy.
