Medicaid covers braces only in specific cases, and the rules depend on your state and age
Most state Medicaid programs do not cover braces for cosmetic reasons. However, many states will pay for orthodontic treatment if a dentist documents that the misalignment causes a functional problem — meaning it affects how you chew, speak, or breathe, not just how your teeth look. Some states cover braces for children but not adults. A few states cover neither. You need to contact your state Medicaid program directly, because coverage rules vary significantly and change year to year.
Even when your state does cover braces, the program usually requires pre-approval before treatment starts. This means a dentist or orthodontist must submit documentation showing medical necessity, and Medicaid must say yes before you begin. If you start treatment without approval, you may have to pay out of pocket.
Key Takeaways
- Medicaid covers braces only when a dentist documents that misalignment affects chewing, speech, or breathing — not for appearance alone.
- Coverage rules and age limits differ by state, so you must check with your specific state Medicaid program to know whether you are covered.
- Most programs require written pre-approval from Medicaid before an orthodontist begins treatment.
- If your state does not cover braces, you may find lower-cost options through dental schools, community health centers, or payment plans offered by private orthodontists.
How states define medical necessity for braces
States that cover orthodontic treatment typically use a measurement system called the Dental Aesthetic Index or Index of Orthodontic Treatment Need to decide whether braces are medically necessary. A dentist takes X-rays and photographs, measures the severity of the misalignment, and documents whether it interferes with function. Purely cosmetic cases — where teeth are crooked but chewing and speech work normally — do not meet this standard.
Examples of conditions that may may have access to include severe overbite or underbite that makes chewing difficult, crowding so severe it causes speech problems, or a bite that strains the jaw joint. The exact threshold varies by state. Some states use a stricter standard and cover only the most severe cases. Others are more lenient. Your orthodontist's office can tell you whether your specific situation meets your state's definition, but Medicaid must approve it in writing before treatment starts.
Age limits and coverage by state
Many states that cover braces limit coverage to children and teenagers, often up to age 18 or 21. Some states cover adults, but this is less common. A handful of states — including Wyoming, Mississippi, and some others — do not cover orthodontic treatment through Medicaid at all, regardless of age or medical need.
States that do cover braces often have waiting lists or limits on how many cases they will approve per year. Some programs also limit coverage to a certain dollar amount, which may not cover the full cost of treatment. You can find your state's specific rules by calling your state Medicaid office or visiting your state's Medicaid website. The phone number is usually on the back of your Medicaid card.
The pre-approval process before starting treatment
If your state covers braces, the orthodontist's office typically handles the pre-approval step. They submit a treatment plan, X-rays, photographs, and a letter explaining why the braces are medically necessary. Medicaid reviews this documentation and either approves or denies the request. This process usually takes two to four weeks, though it can be longer if Medicaid asks for more information.
Do not start braces before you have written approval from Medicaid. If you begin treatment without pre-approval and Medicaid later denies the claim, you will be responsible for the full cost. Ask the orthodontist's office to confirm in writing that Medicaid has approved your case before the first appointment.
What happens if your state does not cover braces
If your state Medicaid program does not cover braces, or if you do not meet the medical necessity standard, you have other options. Many dental schools offer orthodontic treatment at a fraction of private practice cost — usually 30 to 50 percent less — because the work is done by students under supervision. Treatment takes longer (often two to three years instead of one to two), but the quality is the same.
Community health centers and federally may have access to health centers (FQHCs) sometimes offer reduced-cost orthodontics or can refer you to programs that do. Some private orthodontists offer payment plans that let you spread the cost over the treatment period. You can also search for orthodontists who offer sliding-scale fees based on income. Call your local health department or search online for "low-cost orthodontist near me" to find these options.
Coverage for related dental work during orthodontic treatment
If Medicaid covers your braces, it typically covers only the braces themselves and the orthodontist's visits. Regular dental care — cleanings, fillings, X-rays — is usually covered separately under your state's Medicaid dental benefit, if your state offers one. Some states have limited dental coverage for adults, so you may need to check what your plan includes.
If you need a tooth extracted before braces can be placed, or if a tooth needs a root canal during treatment, ask whether Medicaid will cover that work. Coverage varies by state and by the specific procedure. Your orthodontist and dentist can submit a pre-approval request for any additional work that seems necessary.
What to do if Medicaid denies your request for braces
If your state Medicaid program denies your pre-approval request, you have the right to appeal. The denial letter should explain why Medicaid said no and tell you how to request a hearing. You typically have 30 to 60 days to file an appeal, depending on your state. At a hearing, you can present new evidence — for example, a letter from your dentist explaining why the misalignment affects function, or additional X-rays showing the severity of the case.
Before you appeal, ask your orthodontist whether they have successfully appealed similar denials in your state. Some offices have experience with the appeals process and can help you gather the right documentation. If you do not have an orthodontist yet, you can ask your regular dentist to refer you to one who accepts Medicaid and has handled appeals before.
Frequently Asked Questions
Does Medicaid cover braces for adults?
Some states cover braces for adults if they meet the medical necessity standard, but many states limit coverage to children and teenagers. You must check with your state Medicaid program to know whether adult coverage is available in your state and what the age cutoff is.
Will Medicaid cover braces if I have an overbite or underbite?
It depends on how severe the overbite or underbite is and whether it affects how you chew or speak. Mild cases that do not interfere with function usually do not may have access to. Your orthodontist can evaluate whether your specific case meets your state's medical necessity standard.
What if I start braces before Medicaid approves them?
You risk having to pay the full cost yourself. Always wait for written pre-approval from Medicaid before your first orthodontist appointment. Ask the orthodontist's office to confirm approval in writing before you begin treatment.
Can I use Medicaid to pay for teeth whitening or retainers after braces come off?
Medicaid does not cover cosmetic procedures like whitening. Retainers are sometimes covered if they are considered medically necessary to maintain the results of covered orthodontic treatment, but this varies by state. Ask your Medicaid program and orthodontist whether retainers are included.
How do I find out what my state covers?
Call the phone number on your Medicaid card or visit your state's Medicaid website. You can also ask your dentist or orthodontist's office — they work with Medicaid regularly and usually know the current coverage rules for your state.
