After your examination and a discussion of treatment options, your dentist will give you a copy of your initial treatment plan, which will include estimated costs. These costs are estimates only, because your treatment plan may need to change if the dentist finds additional or different problems after actually starting treatment.
If you ask, the billing staff will give you an estimate that includes your out-of-pocket expense. They will also send a pre-estimate to Delta Dental. But you are responsible for understanding what your insurance covers and for paying any balances not paid by the insurance company.
