Dental Insurance Calculator: Out-of-Pocket Cost Estimator

Three numbers decide most of what a dental plan pays. MouthHealthy (ADA) defines the deductible as the amount you are expected to pay out of pocket before your plan begins covering expenses, coinsurance as the cost-sharing that sets what percentage of costs the plan pays, and the annual limit, often called the annual maximum, as the total amount a plan will pay during the plan year. Each one reduces the plan payment at a different stage, which is why a simple percentage of the bill rarely matches what you end up paying.

The calculator applies them one procedure at a time. First, any deductible you have left is taken from the fee. Next, the plan pays its coverage percentage for that category on what remains. Finally, that payment is limited to the annual maximum still available, and the maximum shrinks for the next procedure. Whatever the plan does not pay is your share.

• Deductible: comes off the fee first, until the amount left this year is used up
• Coverage percentage: the plan share of the fee after the deductible, set by category
• Annual maximum: caps the total the plan pays for the rest of the plan year

Many plans pay a different percentage for different kinds of care. The calculator uses three categories: preventive, such as cleanings and exams; basic, such as fillings and extractions; and major, such as crowns, implants and bridges. Your plan may name or group procedures differently, so check your plan summary or ask the dental office which category your plan uses for each procedure on your treatment plan.

MouthHealthy (ADA) notes that some services, for example cleanings and diagnostic services, may be covered with no deductible. That is why the calculator skips the deductible for preventive procedures unless you tick the box saying your deductible also applies to preventive care. It also notes that plans may have frequency limits, such as a cap on cleanings per calendar year, which this estimate cannot see.

Procedures are processed in the order you list them, which is how the deductible and annual maximum are used up in real life as claims arrive. If your annual maximum runs out partway through the list, later procedures receive little or no plan payment and the result flags it. Listing a major procedure first or last can therefore shift which line absorbs the cap, even though the total plan payment for the year is still limited by the same maximum.

When the maximum is reached, the calculator suggests asking whether some treatment could be scheduled in the next plan year, when a new annual maximum applies. Whether that is clinically appropriate is a question for your dentist, not a financial calculation.

HealthCare.gov explains that dental coverage is an essential health benefit for children but not for adults, so health plans are not required to include adult dental coverage. You can get dental coverage as part of a health plan or as a separate dental plan, but a Marketplace dental plan can only be bought at the same time as a health plan. A separate dental plan has its own premium, and separate plans can have waiting periods before they cover services for adults, while premiums are still due.

Before you rely on any estimate, MouthHealthy suggests asking what copayments, coinsurance and deductibles you will be responsible for, what the annual limit is, whether there is a lifetime benefit limit and whether you can choose your own dentist. Real claims also depend on network fee schedules, missing-tooth clauses and coordination of benefits, so for larger treatment plans ask the dental office to submit a pre-treatment estimate to your insurer.
