Dental insurance can be used to cover pretty much any dental treatment you can imagine, but the amount can vary based on what category the plan designates a procedure. Preventive services tend to receive the most coverage, while restorative services usually receive slightly less. Similar to medical insurance, your provider pays for part of a service based on the terms of your plan, and you’re expected to cover the balance at the time of service. Some plans also have copays and deductibles you have to meet before your benefits kick in as well.
