Montana Medicaid Dental Coverage

Updated August 2026

Children enrolled in Montana Medicaid and Healthy Montana Kids receive comprehensive dental benefits under the federal EPSDT mandate. The EPSDT requirement (42 U.S.C. § 1396d(r)) obligates states to cover all medically necessary dental services for enrolled children, regardless of whether a specific service is itemized in the state plan. Montana administers EPSDT dental on a fee-for-service basis.

Most services covered ($1,125/year cap)

Adult dental coverage

Children's dental coverage (under 21)

Delivery model

Standard Medicaid adults get most dental services covered, subject to a $1,125 annual treatment cap

Montana Medicaid provides comprehensive dental to children through EPSDT, with no annual cap. Adults with Standard Medicaid benefits are eligible for almost all medically necessary dental and denturist services, but an annual $1,125 cap applies to dental treatment services (anesthesia, dentures, diagnostic, and preventive services do not count toward the cap). Children age 0-20 and adults determined categorically eligible for Aged, Blind, and Disabled Medicaid are not subject to the cap. Contact DPHHS at 1-800-362-8312 or verify your benefits through the Montana Healthcare Programs dental page at dphhs.mt.gov/MontanaHealthcarePrograms/Dental.

Adult Montana Medicaid dental coverage (age 21 and older)

Members with Standard Medicaid benefits are eligible for almost all dental and denturist services when they are medically necessary, including exams and cleanings every six months. This is more comprehensive than many other states' adult Medicaid dental benefits. Montana administers dental on a fee-for-service basis — there are no separate managed dental plans for adult Medicaid enrollees.

An annual $1,125 cap applies to dental treatment services for adults with Standard Medicaid benefits. Covered anesthesia, dentures, diagnostic, and preventive services do not count toward this cap, and periodic service limits apply. Adults are responsible for the cost of non-covered services and any treatment services received above the $1,125 annual limit. Children age 0-20 and adults categorically eligible for Aged, Blind, and Disabled Medicaid are not subject to the cap.

Noble metal crowns, bridges, and orthodontia are not covered for members 21 and older. Also excluded for adults: no-show appointments, cosmetic dentistry, splints/mouthguards, and dental implants. Partial dentures may be replaced every 5 years and full dentures every 10 years; one lost pair of dentures in a person's lifetime is covered.

Montana's Federally Qualified Health Centers provide dental services to Medicaid members and can also see uninsured or underinsured patients on a sliding-scale fee basis. For adult Medicaid members who need services beyond what Montana Medicaid covers, FQHCs are often the best option.

How to find a Montana Medicaid dental provider

Montana Medicaid operates on a fee-for-service basis for dental — there is no managed care dental network. Use the Montana Healthcare Programs Provider Directory at mtdphhs-provider.optum.com to find a participating dentist, call DPHHS at 1-800-362-8312, or ask your prospective dentist directly whether they accept Montana Medicaid.

Dental provider participation in Medicaid can be limited in rural areas, which is a significant challenge in a geographically large state like Montana. If you cannot find a local Medicaid dentist, ask about teledentistry options or check with your nearest Indian Health Service facility if you are an enrolled tribal member.

For children specifically, school-based dental programs operate in some Montana communities and may be able to connect your child with a participating Medicaid dentist.
