There can sometimes be significant differences between the dental insurance plans that employers sponsor and those that you obtain as an individual. One big (and obvious) difference is that usually employers pay for part or all of the dental insurance plan, whereas if you're buying a plan by yourself you have to pay for the whole thing. Some employers are also able to get a better deal because they're buying insurance in in bulk for all their employees. But, if you shop around, you could potentially get a plan that is similarly priced or even cheaper.
Another kind of dental insurance plan is a DPPO which is similar to a health insurance PPO plan. What they do is they work out lower rates with dentists that are in their network who are often referred to as their preferred providers. With this plan, you can visit a dentist outside of your network, but you will not be able to get these low rates and you will likely end up paying more. Many DPPOs provide coverage of preventative care, basic procedures, and major procedures, but they only provide a percentage of this care for each.
Under the federal law, dental benefits are an optional service for state Medicaid programs. States can include adult dental benefits in their Medicaid programs. Many states do provide dental benefits for adults; however the status and extent of those benefits vary by state and by year, depending on the availability of state funds to support such benefits.
First, you could enroll in a Medicare Advantage plan. Many Medicare Advantage plans include vision, dental, and prescription drug coverage. All of these benefits are coordinated together, so any premium costs will be included in your low (or non-existent) Medicare Advantage premium. Just be aware that dental benefits are usually limited to cleanings, exams, and bitewing X-rays. If you are looking for more comprehensive coverage, you may want to add on a stand-alone dental plan.
The cost of not taking care of your oral health could be more. Those without individual dental coverage are less likely to get routine dental care, meaning they seek out a dentist only when they have a problem. By then, more extensive and more expensive measures may be necessary, and major problems linked to poor oral health (like heart disease and diabetes) are more likely to appear.2 Doing nothing now means you might pay more later.
