Not correct, you are ruling out all insurance based on your experience. Deep cleanings are covered by many, including Medicare supplement plans. It it wasnt legit it would not be covered.
"Preventive and diagnostic coverage includes: Dental exams. X-rays. Routine
cleanings. Fluoride. Fillings.
Deep cleanings. Crowns and bridges. Extractions. Root canals. Dentures. Anesthesia. Dental implants."
The above was a quote from UHC Supplemental Medicare Dental coverage ( I didnt bold type it, that was them) They do have restrictions on how many quadrants can be done to 1 every two years.
Also if it wasnt legit the largest dental insurance company would not say this (unrelated to UHC medicare)
