Since Medicaid is a state program, the services covered by Medicaid vary from state to state. Coverage of dental services by Medicaid is required for individuals under 21. So, any person under 21 who receives Medicaid benefits will have dental coverage included. However, dental services are not guaranteed for those over 21. Some states provide dental coverage, while others do not. If you are unsure about the details of your coverage, you should contact your state Medicaid office to determine whether you have dental coverage.
