It is very important for your oral surgeon to be well versed in oral lesions of all kinds. White patches in the mouth or tongue sores that do not heal are of concern and need to be evaluated promptly. Perhaps your family dentist has advised you to seek out an oral surgeon for a mouth biopsy or thorough oral examination.
If your doctor (remember, your dentist is a doctor - if you have a good one, he won't need to be reminded of that) feels there is an immediate medical necessity for scaling/rooting (aka deep cleaning) such as evidence of damage, then it's probably a good idea to heed the advice.
