There is no age limit for braces. The biological process that moves teeth through bone works the same whether you’re 8 or 80, and age alone is rarely a deciding factor in whether orthodontic treatment can succeed. What matters far more than your birth date is the health of your gums and the bone supporting your teeth.
Nearly 1.91 million adults in the United States are currently in active orthodontic treatment, up from 1.64 million in 2022. The number keeps climbing, and it includes people well into their 60s and 70s.
Why Age Doesn’t Stop Teeth From Moving
Teeth move when sustained pressure is applied over time. Your body responds by gradually remodeling the bone around each tooth root, breaking it down on one side and building it up on the other. This process doesn’t shut off at a certain age. It’s the same cellular mechanism in a 14-year-old as in a 65-year-old.
The main difference is speed. Adults have denser, more mature bone, which means teeth are harder to move. Kids and teens also have jaws that are still growing, giving orthodontists additional flexibility in shaping the bite. For adults, that growth window has closed, so treatment relies entirely on moving the teeth themselves rather than guiding jaw development. The result is typically the same, it just takes a bit longer to get there.
What Actually Determines Whether You’re a Candidate
Instead of asking about age, an orthodontist will evaluate three things: your bone density, your gum health, and the overall condition of your teeth. These are the real gatekeepers.
Bone loss from gum disease is the most common issue that complicates adult treatment. If the bone supporting your teeth has thinned significantly, moving teeth through it becomes riskier. That said, bone loss doesn’t automatically disqualify you. Mild to moderate loss can often be managed with careful treatment planning, and in some cases a bone graft can rebuild tissue before treatment begins. The key is that gum disease needs to be under control first. Active inflammation and ongoing bone loss make orthodontics unsafe regardless of age.
Poor oral hygiene is another concern. Braces create more surfaces for plaque to collect, and if your gums are already inflamed, that extra buildup can accelerate bone loss during treatment. Your orthodontist will want to see healthy, stable gums before putting brackets on your teeth.
Risks That Increase With Longer Treatment
One risk worth understanding is root resorption, where the tips of your tooth roots shorten slightly during treatment. Some degree of this happens in most orthodontic patients and is usually harmless. But about 4% of patients experience more than 3 millimeters of root shortening, and roughly 5% of adults develop more significant resorption of 5 millimeters or more in at least one tooth. For comparison, only about 2% of adolescents reach that threshold.
The biggest risk factors aren’t age itself but treatment duration and the amount of tooth movement required. Longer treatment with heavy forces, especially when teeth need to be moved large distances, increases the likelihood of significant root shortening. Certain root shapes also carry higher risk. People with naturally pointed or narrow roots are more prone to resorption than those with rounded, bulkier roots. Your orthodontist can assess this on an X-ray before treatment starts and monitor it along the way.
How Long Adult Treatment Takes
Most adult orthodontic treatment falls in the range of 12 to 36 months, depending on the type of appliance and the complexity of the case.
- Traditional metal braces: 18 to 36 months
- Ceramic braces: 18 to 36 months or slightly longer
- Lingual braces (placed behind the teeth): 24 to 36 months
- Clear aligners: 12 to 24 months
Clear aligners tend to be faster because they’re typically used for less complex cases. If you have severe crowding, significant overlap, or complicated bite issues, traditional braces are often the better tool. Clear aligners and lingual braces simply can’t generate the same forces needed for major corrections.
Adults generally land on the longer end of each range compared to teens with similar problems. Denser bone means each stage of movement takes more time, and orthodontists often use lighter, more gradual forces in adult patients to protect bone and root health.
Orthodontic Options for Adults
Adults tend to care more about aesthetics during treatment, which is why options beyond traditional metal brackets have become so popular. Ceramic braces use tooth-colored brackets that blend in. Lingual braces sit on the back surfaces of your teeth, making them essentially invisible. Clear aligners are removable plastic trays that you swap out every week or two, and most people won’t notice you’re wearing them.
The trade-off with discreet options is that they don’t work for every situation. Severe crowding, complex bite problems, and cases requiring significant tooth movement often still need traditional braces. If appearance during treatment is a priority for you, bring it up early so your orthodontist can tell you honestly which options are realistic for your specific case.
What Insurance Typically Covers
Here’s where age does create a real barrier: money. Many dental insurance policies cap orthodontic coverage at age 19. If you’re older than that, your plan may offer no orthodontic benefit at all, or a reduced one. This means adults often pay more out of pocket than teens for the same treatment.
The average cost of braces for adults ranges from $3,000 to $10,000, depending on the type of appliance, the length of treatment, and where you live. Most orthodontic offices offer payment plans, and some flexible spending or health savings accounts can be used to cover part of the cost. It’s worth checking your specific policy carefully, because some adult plans do include partial orthodontic benefits even past the typical age cutoff.
Considerations for Older Adults
For patients in their 50s, 60s, and beyond, the treatment itself works. The considerations are more practical. Older adults are more likely to have existing dental work like crowns, bridges, or implants that affect how braces are placed. Dental implants, unlike natural teeth, are fused directly to bone and cannot be moved, so treatment has to be planned around them. Older adults are also more likely to have some degree of gum disease or bone loss that needs to be addressed before orthodontics can safely begin.
The reasons older adults seek braces vary. Some want to fix lifelong cosmetic concerns. Others develop shifting or crowding later in life as teeth naturally drift with age. In many cases, straightening teeth in older adults isn’t purely cosmetic. Aligned teeth are easier to clean, which helps protect against further gum disease and tooth loss. Correcting a bite can also reduce uneven wear on teeth and ease jaw discomfort.
