my dental plan says it covers periodontal exams. Does this mean it will cover the cleaning needed after I have this exam as well? or is it just the visit to determine what is needed that is covered?The term the dentist office used was "deep cleaning". and it cost me almost $2000 for this process. I also have a dependent who will need 2 wisdom (surgery) teeth pulled. Should I expect to pay for this 100% as well?
