Conclusion
Medicare generally does not cover dental care services but some situations allow it to. Medicare covers dental procedures that are required to treat certain underlying conditions which original Medicare covers. Once you are treated, Medicare will no longer cover any follow up dental treatment.
Original Medicare will not cover any dental care services you primarily go to the hospital for. Other plans like Medicare Advantage or dental insurance are helpful in situations like this. You can also look for a walk-in dental clinic around your community.
Medicaid also helps to cover dental services in some states in the U.S. When you get enrolled into Medicaid, ask your insurer about the dental services that are covered by the plan. Dental services covered by Medicaid vary across the states in the U.S.
