What do you if a dentist charges an filing but your dental insurance contract says they

If a dentist charges a filing fee but your dental insurance contract says they should not, you should first try to resolve the issue directly with the dentist. Explain that your dental insurance contract does not allow for filing fees and ask them to waive the fee. If the dentist refuses, you can contact your dental insurance company and file a complaint. The dental insurance company will investigate the matter and may take action against the dentist if they find that the dentist has violated the terms of the contract.
