New Hampshire Medicaid dental coverage

Last verified: June 2026

Dental coverage for children (under 21)

Children enrolled in NH Medicaid receive dental services through the fee-for-service delivery system — not through the managed care plans that handle most other NH Medicaid services. This means you do not call your MCO (AmeriHealth Caritas, NH Healthy Families, or WellSense) for dental questions for your child. Instead, contact NH DHHS directly or use the Medicaid provider search for fee-for-service dental providers.

The federal EPSDT mandate (42 U.S.C. § 1396d(r)) requires New Hampshire to cover all medically necessary dental services for members under 21. EPSDT sets a comprehensive floor — NH cannot cap the dental benefit for children below what is medically necessary.

• Preventive oral exams and teeth cleanings
• Fluoride treatments and dental sealants
• Diagnostic X-rays
• Fillings and restorations
• Tooth extractions
• Space maintainers for missing teeth
• Root canal treatment on primary and permanent teeth
• Orthodontic treatment when medically necessary
• Emergency dental care
• Oral surgery when medically necessary

Adult dental coverage: NH Smiles

New Hampshire provides adult dental benefits through the NH Smiles program — a Medicaid dental benefit integrated into the managed care package. Not all states cover adult dental at all; NH Smiles positions New Hampshire as a state with a more complete adult dental benefit than the bare-minimum emergency-only coverage seen elsewhere.

Covered adult dental services through NH Smiles typically include:

• Preventive oral exams (limited to one per year)
• Teeth cleanings
• Diagnostic X-rays
• Simple extractions
• Fillings for posterior and anterior teeth
• Emergency dental treatment
• Dentures with prior authorization

More complex procedures such as crowns, bridges, and oral surgery may require prior authorization. Cosmetic dental work is not covered. Contact your MCO member services line for the NH Smiles benefit details specific to your plan.

Finding a dental provider in New Hampshire

For adult dental (NH Smiles), contact your MCO for a list of in-network dental providers. Each of the three MCOs — AmeriHealth Caritas New Hampshire, NH Healthy Families, and WellSense Health Plan — maintains its own dental provider network directory.

For children's dental (fee-for-service), use the NH DHHS Medicaid provider search at dhhs.nh.gov or call 1-844-275-3447 to find a fee-for-service dental provider who accepts NH Medicaid.

Federally Qualified Health Centers (FQHCs) and community health centers in New Hampshire provide dental services on a sliding-fee scale and frequently accept NH Medicaid. Use the HRSA Health Center Finder at findahealthcenter.hrsa.gov to locate a community health center near you — this is particularly useful in rural NH where private dental practices accepting Medicaid may be limited.

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 New Hampshire 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 New Hampshire Medicaid or CHIP are entitled to this full EPSDT dental benefit regardless of what New Hampshire 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:
