You’ve probably seen them on celebrities or your coworkers and never even realized it. That’s the whole point. While everyone else is walking around with a mouth full of ceramic brackets or those plastic aligner trays that make you lisp, there is a third option that stays completely out of sight. They’re called lingual braces. Basically, they are braces behind your teeth.
Most people think orthodontic work is a choice between looking like a teenager for two years or remembering to swap out clear plastic trays twenty-two hours a day. Honestly? Both of those options can be a massive pain. Lingual braces flip the script by moving the entire hardware setup to the tongue-side of your teeth. No one knows they are there unless you open your mouth wide enough for a dental exam.
But there is a catch. Or a few.
It isn't just about hiding the metal. It’s about how they actually work. Because the back of your teeth has a much more complex shape than the front, you can’t just slap on "off-the-shelf" brackets. Everything has to be custom-made. It’s a feat of engineering that most patients don't really appreciate until they feel how perfectly those tiny gold or steel pads fit against their anatomy.
The Tech That Makes Hidden Braces Possible
If you’re looking into this, you’ll keep seeing the name Incognito. That’s the brand owned by 3M, and it’s basically the gold standard in this world. They use CAD/CAM technology—basically 3D printing and digital modeling—to create brackets that are specific to your mouth and your mouth only. Another big player is InBrace, which uses a "Smartwire" that’s programmed to move your teeth without the constant manual tightenings you’d get with old-school tracks.
Why does this matter? Because your teeth are shaped differently on the back. The "lingual" surface is irregular. If a doctor tried to use standard brackets on the back, they’d pop off the second you bit into a sandwich. Plus, the distance between the brackets is shorter on the inside curve of your jaw, which makes the physics of moving teeth way more complicated.
Is it actually "invisible"?
Pretty much.
Unless someone is literally looking down your throat while you laugh, they won't see a thing. This is a huge win for professionals—think trial lawyers, news anchors, or anyone in sales—who don't want their dental work to be the first thing people notice. It’s the only truly "stealth" option. Even "clear" aligners have those little tooth-colored bumps (attachments) that catch the light. Braces behind your teeth have none of that.
The Real Talk on Comfort and Speech
Let's be real for a second: the first two weeks are going to be annoying. Your tongue is used to having all that space to move around, and suddenly there’s a metal "jungle gym" in the way. You will probably lisp. You might sound a bit like you’ve had a few drinks when you try to say words with "s" or "th" sounds.

It’s temporary. The tongue is an incredibly adaptive muscle.
Most patients find that after about ten days, the lisp disappears. But during that first week? You’ll want plenty of dental wax. Since the brackets are right next to your tongue, you might experience some soreness. Dr. Ron Ead, a well-known orthodontic patient advocate who has documented his own lingual journey, often points out that the "break-in" period for lingual is steeper than traditional braces, but the payoff of not seeing them in the mirror every morning makes it worth it for many.
Also, eating is different. You have to be careful. You can’t just go to town on a cob of corn or a bag of beef jerky. But that’s true for any fixed braces. The difference here is that if you get a piece of spinach stuck in your braces, it’s on the back. You won’t be that person walking out of a business lunch with a green leaf stuck to your front tooth.
Efficiency: Are They Faster Than Invisalign?
There is a huge misconception that lingual braces take longer. Actually, for certain types of bite corrections—like closing an open bite or fixing deep overbites—lingual braces can sometimes be more efficient than clear aligners.
The reason is simple: mechanical advantage.
Because the brackets are closer to the "center of resistance" of the tooth, the orthodontist has a lot of control over the root movement. You aren't relying on a piece of plastic to "push" the tooth; you have a wire actively pulling it into the right spot 24/7. And unlike aligners, you can't lose them. You can't "forget" to wear them. They are working while you sleep, eat, and work.
However, not every orthodontist offers them. It’s a niche skill. It requires specialized training because working on the back of the teeth is physically demanding for the doctor—they’re basically working in a mirror, upside down. If you want these, you have to find a "lingual specialist," not just a general dentist who does some ortho on the side.
The Cost Factor
Let's not sugarcoat it. Braces behind your teeth are expensive.

Expect to pay anywhere from $2,000 to $5,000 more than you would for traditional metal braces. Why the markup?
- Labor: Your appointments take longer.
- Customization: Every single bracket is a custom-poured piece of metal.
- Lab Fees: The digital setup and robotic wire bending cost the doctor a fortune before they even put them in your mouth.
In the U.S., you're typically looking at a range of $8,000 to $13,000 total. Insurance usually covers the same flat amount they would for any other orthodontic treatment, so the "luxury" upcharge comes out of your pocket.
Maintenance and Daily Life
Hygiene is the biggest hurdle. You can't see what you're cleaning. You’ll need to become best friends with a Waterpik. Standard flossing is basically impossible without threaders, and even then, it’s a bit of a workout for your fingers.
If you aren't a disciplined brusher, lingual braces might not be for you. Decay on the back of the teeth is just as bad as decay on the front, and it's much harder for a dentist to fill those cavities later.
- Invest in a high-end electric toothbrush. The vibration helps shake loose food particles you can’t see.
- Use an interdental brush. These little "Christmas tree" brushes are perfect for poking between the wire and the tooth.
- Get regular cleanings. You might want to see your dental hygienist every 3 or 4 months instead of every 6 while the braces are on.
Who Is Actually a Good Candidate?
Most adults and teens are candidates, but there are exceptions. If you have an extremely deep overbite—where your top teeth completely overlap your bottom teeth—you might end up biting down directly on the lower brackets. This can cause the brackets to break off repeatedly. A good orthodontist will use "bite blocks" (temporary bumps on your molars) to keep your teeth apart while the alignment shifts to prevent this.
Also, if you have very small teeth, there might not be enough "real estate" on the back to bond the bracket securely.
Why not just get Invisalign?
Clear aligners are great, but they require 22 hours of daily wear. Many people—honestly, more than would like to admit it—simply don't have the discipline. They take the trays out for coffee, leave them on the nightstand, and suddenly they've gone six hours without movement.
With braces behind your teeth, the "compliance" factor is zero. Once they’re in, they’re in. You don't have to think about them again until your next adjustment.

One weirdly cool thing about lingual braces is how they affect your facial profile. Because there is no hardware on the front of your teeth, your lips don't "pout" out the way they do with traditional braces. Your smile looks exactly like it did before, just gradually straighter.
There is also less risk of "white spots." When people get traditional braces and don't brush well, they sometimes end up with permanent white square marks on the front of their teeth where the brackets were. Since the back of the tooth is more resistant to this kind of decalcification (thanks to constant bathing in saliva), the risk of cosmetic damage to the "visible" part of your smile is much lower.
Actionable Steps to Take Right Now
If you're tired of your crooked teeth but refuse to wear "train tracks," here is exactly how to move forward with lingual orthodontics.
First, don't just call any dentist. Use the "Find a Provider" tools on websites like Incognito or InBrace. You want someone who does this every day, not once a year. A doctor who rarely does lingual work will take longer and the results might not be as precise.
Second, book a consultation and specifically ask about "bite interference." Ask the doctor: "Based on my current bite, will I need bite blocks, and how long will the lisp likely last?" This shows them you know your stuff and forces a realistic conversation about the first few weeks of treatment.
Third, check your FSA or HSA. Since this is a major medical expense, using pre-tax dollars can save you 20-30% effectively. Most offices will let you split the payments over two years, which aligns perfectly with how these accounts are funded.
Finally, prepare your "survival kit." Before your bonding appointment, buy:
- GUM Orthodontic Wax (the silicone kind stays on better).
- A Waterpik (the cordless version is fine).
- Alcohol-free numbing rinse (like Rincinol) for those first few days of tongue soreness.
Braces behind your teeth are a commitment. They’re a bit of a hidden struggle for a totally hidden result. If you can handle a week of "th" sounds and a slightly higher price tag, they are arguably the most sophisticated way to get a perfect smile without anyone ever knowing you were "fixing" it in the first place.
