Medicaid covers braces for children in most states, but only when a dentist or orthodontist documents that the teeth need correction for medical reasons, not appearance alone.

Whether your state's Medicaid program pays for braces depends on three things: your age, the severity of your dental problem, and your state's specific rules. Most states cover orthodontic treatment for children under 18 or 19 when a professional shows the misalignment affects chewing, speech, or jaw function. Adult coverage is rare — only a handful of states pay for braces for people over 21, and usually only after oral surgery or injury.

The process starts with a referral from your primary care dentist or your child's pediatrician to an orthodontist who accepts Medicaid. That orthodontist must submit documentation — usually X-rays, photos, and a clinical assessment — to your state Medicaid program for pre-approval before treatment begins. If approved, Medicaid typically covers the full cost of the braces themselves and periodic adjustments, though some states require a small copay per visit.

Key Takeaways

  • Most states cover braces for children when a dentist documents that misalignment affects function, not just appearance.
  • Your state Medicaid program must pre-approve treatment before the orthodontist places braces, which requires X-rays and clinical documentation.
  • Coverage for adults is uncommon and usually limited to cases involving jaw surgery, injury, or specific medical conditions.
  • You must see an orthodontist who accepts your state's Medicaid — not all do — and your primary care dentist can provide a referral.

How states define "medically necessary" braces

Medicaid programs distinguish between orthodontic treatment for medical reasons and treatment for cosmetic reasons. A tooth that is slightly crooked but functions normally will not be covered. A severe overbite that makes chewing difficult, an underbite that affects speech, or crowding so severe that teeth cannot be cleaned properly — these are the kinds of problems Medicaid considers medically necessary.

Each state uses its own standard to measure severity. Some states use the Dental Aesthetic Index or the Index of Orthodontic Treatment Need, which are scoring systems that measure how far teeth deviate from normal alignment. Others rely on the orthodontist's clinical judgment. A few states have a dollar threshold: they will only cover braces if the cost of leaving the problem untreated (such as tooth decay from inability to clean crowded teeth) would exceed the cost of braces.

Your state Medicaid dental program publishes its coverage rules in a document called the State Plan or the Medicaid Dental Coverage Guide. You can find this on your state Medicaid website, usually under "Dental Services" or "Orthodontics." If the rules are unclear, call your state Medicaid dental director's office — they can tell you whether your specific situation meets the threshold.

The pre-approval process and what you need

Before any braces are placed, the orthodontist must request pre-approval from your state Medicaid program. This is not optional — if treatment begins without approval, Medicaid will not pay, and you will be responsible for the full bill. The orthodontist's office usually handles this paperwork, but you should confirm they have submitted it and ask for a tracking number.

Pre-approval typically requires the orthodontist to submit a treatment plan that includes clinical photographs, X-rays (usually a panoramic X-ray and a lateral cephalometric X-ray), a written description of the problem and how braces will fix it, and an estimate of the total cost and length of treatment. This packet goes to your state Medicaid program's dental review unit, which may approve it, deny it, or request more information.

The review process usually takes two to four weeks. Some states use an in-house dentist to review; others contract with a dental benefits company. If Medicaid denies the request, the orthodontist can appeal with additional documentation, or you can file your own appeal through your state Medicaid program's standard appeal process. The appeal important date is usually 30 days from the denial letter.

What Medicaid pays for and what you may owe

When Medicaid approves braces, coverage typically includes the initial placement of the braces, monthly or quarterly adjustment visits for the duration of treatment (usually 18 to 36 months), and removal of the braces at the end. Some states also cover retainers — the device worn after braces to keep teeth in place — though others consider retainers a separate service with different coverage rules.

Medicaid does not usually cover cosmetic add-ons like tooth-colored brackets or clear aligners instead of traditional metal braces, even if the underlying orthodontic problem is medically necessary. If you choose these options, you pay the difference out of pocket. Some states also exclude certain types of treatment, such as braces for a second time if you had them before, or braces combined with jaw surgery (though they may cover the surgery separately).

Most states require a copay per visit — typically $1 to $5 — but some states have no copay for orthodontic care. A few states have an annual limit on what they will spend on braces per person. Check your state Medicaid dental coverage guide or call your state dental director to learn what you may owe out of pocket.

Coverage rules by age: children versus adults

Medicaid coverage for braces is much more common for children than for adults. Most states cover orthodontic treatment for children up to age 18 or 19 (the age varies by state). Some states extend coverage to age 21 if treatment began before the child turned 18. A few states have no age limit for children in foster care or with special health care needs.

Adult coverage is the exception. Only about 10 states cover braces for adults, and usually only in narrow circumstances: after oral surgery to correct a severe jaw problem, after an injury to the mouth or face, or as part of treatment for a cleft palate or similar condition. Even in these states, the adult must show that the braces are medically necessary to restore function after the surgery or injury, not straightforward to improve appearance.

If you are an adult and your state does not cover braces through Medicaid, you may have other options. Some community health centers offer reduced-cost orthodontic care on a sliding fee scale. Dental schools sometimes provide braces at a lower cost as part of student training. Your primary care dentist can refer you to these programs.

Finding an orthodontist who accepts Medicaid

Not every orthodontist accepts Medicaid, and acceptance varies by state. Some orthodontists accept Medicaid in one state but not another. Before you schedule a consultation, confirm that the orthodontist is in-network for your state Medicaid program and that they accept new Medicaid patients.

You can find participating orthodontists through your state Medicaid website, which usually has a provider search tool. You can also call your state Medicaid dental program directly and ask for a list of orthodontists in your area. Your primary care dentist or pediatrician can also refer you to an orthodontist they know accepts Medicaid.

When you call to schedule, tell the office that you have Medicaid and ask if they will submit the pre-approval paperwork. Some offices do this routinely; others expect you to request it. Confirm in writing that pre-approval has been submitted before you go to the first appointment, so there is no confusion later about whether Medicaid will pay.

What happens if Medicaid denies coverage

If your state Medicaid program denies the pre-approval request, the orthodontist will send you a denial letter explaining the reason. Common reasons include: the misalignment does not meet your state's severity threshold, the treatment plan does not match your state's coverage rules, or the documentation submitted was incomplete.

You have the right to appeal. The denial letter will include instructions for filing an appeal, usually within 30 days. You can appeal on your own or ask the orthodontist to appeal on your behalf. An appeal typically involves submitting additional clinical information — for example, a letter from your dentist explaining why the problem affects function, or additional X-rays showing the severity.

If the appeal is also denied, you can request a hearing before a state Medicaid hearing officer. This is a formal process, but you do not need a lawyer. The hearing officer will review the clinical evidence and your state's coverage rules and make a final decision. If you lose the hearing, you can pursue further legal action, though this is uncommon for orthodontic coverage disputes.

Frequently Asked Questions

Does Medicaid cover braces for cosmetic reasons?

No. Medicaid only covers braces when a dentist documents that the misalignment affects chewing, speech, or jaw function. Slight crowding or a minor overbite that does not interfere with function will not be covered, even if it affects appearance.

Can I choose clear aligners instead of metal braces if Medicaid covers my treatment?

Most states cover only traditional metal braces through Medicaid. Clear aligners and tooth-colored brackets are usually considered cosmetic upgrades, and you would pay the difference out of pocket if you choose them. Ask your orthodontist what your state Medicaid program covers before deciding.

What if my child's orthodontist says braces are needed but Medicaid denies coverage?

You can appeal the denial within 30 days. Ask the orthodontist to submit additional documentation — such as X-rays showing the severity or a letter explaining how the misalignment affects function. If the appeal is denied, you can request a hearing before a state Medicaid hearing officer.

Do I have to pay for braces upfront and then get reimbursed by Medicaid?

No. Once Medicaid pre-approves treatment, the orthodontist bills Medicaid directly. You pay only your copay (if your state requires one) at each visit. You should never have to pay the full cost upfront and wait for reimbursement.

Will Medicaid cover braces a second time if my teeth shifted after the first treatment?

This depends on your state. Some states cover braces only once per person. Others will cover a second round if the shift was caused by a medical problem (such as a jaw growth issue) rather than failure to wear a retainer. Ask your state Medicaid dental program about their policy on retreatment.
