Oregon Medicaid dental coverage
Last verified: June 2026
Dental benefits vary by state and change with budget cycles
OHP covers comprehensive dental for adults and children — delivered through your CCO
Adult dental coverage under OHP Plus
Oregon is one of a smaller group of states that cover comprehensive dental for adults through Medicaid. Per OHA's benefits page, OHP Plus dental includes the following services for adults:
- Preventive care: exams, cleanings, and diagnostic X-rays
- Fillings — amalgam and composite resin
- Root canal therapy (endodontic treatment)
- Tooth extractions — simple and surgical
- Crowns and other restorative services when medically necessary
- Dentures and partial dentures (prosthodontics)
- Periodontal (gum) disease treatment
- Oral surgery
- Emergency dental services for acute pain or infection
Not all services are covered without limit. Some procedures require prior authorization from your CCO before you schedule an appointment. Contact your CCO's dental line to confirm coverage and find an in-network dentist before scheduling major dental work. Oregon's OHP dental benefit is delivered through the CCO — the same organization that coordinates your physical health care.
Children's dental coverage under OHP Plus
Children enrolled in OHP Plus receive comprehensive dental under the federal EPSDT mandate (42 U.S.C. § 1396d(r)), which requires states to cover all medically necessary dental services for members under age 21. Per OHA, child dental benefits include:
- Dental exams and preventive cleanings
- Fluoride treatments and dental sealants
- Diagnostic X-rays
- Fillings and restorative care
- Extractions
- Root canal treatment when medically necessary
- Orthodontics when medically necessary (functional, not cosmetic)
- Space maintainers
- Emergency dental services

Finding an OHP dentist through your CCO
Dental providers for OHP members are managed through each member's CCO. Each CCO maintains its own dental provider directory. To find a dentist:
- Check your CCO member card — it lists your CCO name and their member services phone number
- Call your CCO's member services line to request a list of in-network dentists near you
- Visit your CCO's website — most publish a searchable provider directory online
- Contact OHA at 1-800-273-0557 if you don't know which CCO you belong to
Rural Oregonians in areas with few dental providers have another option: Federally Qualified Health Centers (FQHCs) are required to accept OHP and provide dental services. HRSA maintains an FQHC locator at findahealthcenter.hrsa.gov. Oregon's rural communities — particularly eastern Oregon and parts of the coast — rely heavily on FQHCs for dental access.
OHP Dental — the dental-only program
Separate from regular OHP Plus dental coverage, Oregon operates an OHP Dental program that provides dental-only benefits for eligible Oregon Veterans and Compact of Free Association (COFA) citizens — residents from the Marshall Islands, Federated States of Micronesia, and Palau who live in Oregon. This separate program covers dental services for individuals who do not qualify for full OHP Plus but meet specific criteria. Per OHA, COFA citizens gained access to full OHP benefits beginning in 2023, so some previously enrolled in OHP Dental may now qualify for full OHP Plus coverage. Contact OHA at 1-800-699-9075 to determine current eligibility.
Dental coverage in Medicaid: what to know
Medicaid dental coverage is not uniform across states. Federal law requires comprehensive dental care for children under 21 through Early and Periodic Screening, Diagnostic, and Treatment (EPSDT). Adult dental is optional — states can offer emergency-only coverage, limited coverage, or a full dental benefit. Several states have reduced or eliminated adult dental during budget cuts, then restored it later.
The practical result: two people in different states with identical income and family circumstances can have very different dental coverage. Children's dental is the one reliable floor; adult coverage depends entirely on what Oregon has chosen to fund.
Children's dental coverage (under 21)
Under the EPSDT mandate — codified in 42 U.S.C. § 1396d(r) — Medicaid must cover all medically necessary dental services for enrollees under 21 in every state. This is one of the few areas where the federal floor for Medicaid is genuinely comprehensive: states cannot restrict children's dental coverage the way they can adult coverage.
EPSDT dental includes preventive care (cleanings, fluoride treatments, sealants), diagnostic X-rays, restorative work (fillings, crowns), extractions, orthodontia when medically necessary, and emergency dental care. The "medically necessary" standard is broad for children — if a dentist certifies that a service is needed for the child's health, Medicaid must cover it.
Children covered by Oregon Health Plan (OHP) or CHIP are entitled to this full EPSDT dental benefit regardless of what Oregon provides to adults.
Adult dental coverage (age 21 and older)
Adult Medicaid dental falls into three general tiers across states, though the specifics vary considerably:
Emergency only
Covers tooth extractions and treatment for acute dental pain or infection. No preventive cleanings, fillings, or restorative work covered.
Limited coverage
Covers emergency services plus some preventive care and basic restorative work (fillings). Typically excludes orthodontia, implants, and more complex procedures.
Comprehensive coverage
Covers the full range of dental services — preventive, diagnostic, restorative, and sometimes orthodontic — comparable to commercial dental insurance. Available in fewer than half of states.
