Again, become an informed customer. Ask before they do anything in your mouth and bring the GEO benefit sheet so that they know you are careful. The most frequent question I ask is, is it included in my insurance? Look at my own GEO benefit sheet and ask them which one service they're giving me. Tell them that I would only be willing to do the procedures listed in this list. They are willing to call delta dental to verify uncleared info if you insist on making it clear before the procedure. Ask for pre-estimate in case you're not sure about the total fee, esp for big operation. It's our right, so don't hesitate to demand clarity.
The dental benefit is actually very good if we can use it carefully.
