Idaho Medicaid Dental Coverage
Updated August 2026
Idaho Medicaid covers comprehensive dental benefits for members under 21 under the federal EPSDT mandate (42 U.S.C. § 1396d(r)). Federal law requires states to provide all medically necessary dental treatment for this age group, regardless of whether the state covers the same services for adults.

Idaho adult Medicaid dental is broader than many states — but a 2026 budget proposal could cut it
Idaho Medicaid provides comprehensive dental care for members under 21 through the federal EPSDT mandate. Adults age 21 and older also get real coverage — cleanings, exams, X-rays, fillings, extractions, and root canals through the Idaho Smiles program — with no annual benefit maximum, according to MCNA Dental, the statewide administrator. However, in January 2026 Idaho Gov. Brad Little proposed removing adult Medicaid dental coverage as part of a package of budget cuts; as of this writing that proposal has not been enacted and would require the Legislature to change state policy. Idaho cut adult dental after the 2011 recession and restored it in 2014-2018 after emergency-room costs rose. Verify your current benefits by calling Idaho Smiles/MCNA Dental at 1-855-233-6262.

How to find an Idaho Medicaid dental provider
More complex or major restorative work — beyond the standard Enhanced Plan benefits — may still require prior authorization. If you need extensive dental work, contact MCNA Dental to ask about prior authorization for medically necessary services not automatically covered.
Idaho Medicaid dental services statewide are administered by MCNA Dental under the Idaho Smiles program — a single dental plan, separate from Idaho's medical managed care plans. Use MCNA's online provider directory or call the Member Hotline to find participating dentists.
Idaho's Federally Qualified Health Centers (FQHCs) provide dental services to Medicaid members and typically accept patients regardless of their ability to pay. Idaho State University's College of Pharmacy and Health Sciences also runs dental hygiene programs in Pocatello and Meridian that provide preventive dental services at reduced cost.
