find a plan

If I buy a dental insurance plan, what sort of out-of-pocket costs should I expect?

Q. If I buy a dental insurance plan, what sort of out-of-pocket costs should I expect?

A. For adults, it depends entirely on the amount of dental care you need during the year. But for children, the Affordable Care Act has imposed regulations that limit out-of-pocket costs for dental care.

For families who purchase stand-alone pediatric dental coverage (a plan that’s separate from the children’s health insurance), the maximum out-of-pocket for pediatric dental expenses cannot exceed $350 for one child, or $700 for two or more children on the same policy. These amounts started to be subject to inflation adjustments with plan years beginning after 2017. But based on the formula HHS is using, there has not yet been any change in the amount, and it’s still $350 and $700 as of 2021 (this is because the inflation adjustment amount is still less than $25, and the rules call for the amount to be rounded down to the nearest multiple of $25).

[note that as of 2019, HHS eliminated the requirement that stand-alone pediatric dental plans fall into one of two narrow actuarial value ranges; this rule change allows insurers more flexibility in terms of how they design pediatric dental plans, but the cap on out-of-pocket costs remains in place.]

But when pediatric dental coverage is embedded in a medical plan, the maximum out-of-pocket can be as high as $8,550 for a single individual and $17,200 for a family in 2021, including both medical and dental services combined.

In both cases, these limits are a result of the ACA; prior to 2014, there were no upper bounds on how high a health or dental plan could set their maximum out-of-pocket limits.

Carriers can also offer bundled coverage, with medical insurance and pediatric dental plans sold and billed together, but administered as separate policies with their own out-of-pocket limits. In that scenario, the $350-per-child / $700-per-family out-of-pocket limit applies for pediatric dental.

Out-of-pocket not capped on adult plans

However, out-of-pocket exposure is not capped on adult dental plans, unless the insured happens to have one of the very few health insurance plans that embed adult dental coverage. And, as noted above, the only out-of-pocket limits that apply in that case are the out-of-pocket maximums for the overall coverage, including medical costs.

Stand-alone adult dental plans are not required to have any limits on out-of-pocket exposure. These plans were not required to make any changes as a result of the ACA.

Instead of out-of-pocket maximums, adult dental coverage typically comes with benefit maximums; they cap the amount the insurance company will pay, rather than capping the amount that the insured pays (note that dollar benefit maximums are no longer allowed to apply to pediatric dental coverage, since it’s one of the essential health benefits).

In most cases, stand-alone dental coverage for adults comes with annual benefit caps that range from $1,000 to $2,000. For the most part, these benefit limits haven’t changed since the 1970s and 1980s when dental plans first came on the scene – despite the fact that dental care is much more expensive now.

Typically, dental insurance plans provide significant benefits for diagnostic and preventive care, including exams, x-rays, and cleanings, often covering them completely. And for relatively minor restorative work, like fillings and extractions, a dental insurance policy typically covers a large portion of the charges.

But for procedures like root canals, crowns, and implants, it’s easy to exceed the benefit maximum, particularly if you need treatment for more than one tooth. In addition, many dental insurance plans have waiting periods before they cover dental work beyond preventive and basic care.
