Misaligned teeth can be fixed with several approaches, from braces and clear aligners to palate expanders and, in severe cases, jaw surgery. The right option depends on what kind of misalignment you have, how severe it is, and whether the problem is in your teeth, your jaw, or both. Most orthodontic treatment takes 18 to 24 months, with costs ranging from about $2,750 to $10,000 or more.
Types of Misalignment
Not all crooked teeth are the same problem. An overbite means your upper teeth overlap your lower teeth more than they should in a deep vertical bite. An underbite is the opposite: your lower front teeth extend beyond the upper ones. A crossbite means some of your upper teeth sit inside your lower teeth when you close your mouth, rather than outside where they belong.
Then there’s crowding, which happens when your teeth are too large for the space in your jaw. Crowded teeth overlap, twist, or get pushed forward or backward because there simply isn’t room for them to line up. Sometimes several of these issues show up together, and your treatment plan will need to address each one.
Why Misalignment Is Worth Fixing
Crooked teeth aren’t just a cosmetic issue. Because misaligned teeth are harder to brush and floss properly, they raise your risk of tooth decay and gum disease. Teeth that don’t meet correctly can grind against each other in uneven ways, wearing down enamel over time. Protruding upper front teeth are also more vulnerable to chipping or breaking from impact.
The effects go beyond your teeth. A misaligned bite can strain your jaw joints, causing aching, clicking, popping sounds, or a jaw that feels “blocked” and won’t open wide. Jaw muscles can become chronically tense. In some cases, teeth dig painfully into the lips or gums on the opposite side when you close your mouth. Severe misalignment can affect chewing, speech, and breathing.
How Orthodontic Treatment Moves Teeth
Braces and aligners work because your jawbone is living tissue that remodels itself under pressure. When an orthodontic appliance pushes on a tooth, the ligament connecting the tooth to the bone gets compressed on one side and stretched on the other. On the compressed side, specialized cells break down bone, creating space for the tooth to shift into. On the stretched side, other cells build new bone to fill the gap left behind. This cycle of breaking down and rebuilding is why orthodontic treatment takes months, not weeks. The force has to be gentle and sustained so the bone can remodel safely without damaging the tooth root.
Traditional Metal Braces
Metal braces remain the most versatile option for fixing misaligned teeth. Brackets are bonded to each tooth and connected by an archwire that applies steady pressure. Your orthodontist adjusts the wire periodically to guide teeth into position. Braces can handle virtually any type of misalignment, including complex cases involving root movement, arch expansion, and precise vertical adjustments like pushing teeth up or pulling them down.
The average treatment time with traditional braces is about 24 months. They typically cost between $2,750 and $7,500, making them the most affordable orthodontic option for most people. With insurance, out-of-pocket costs often fall between $1,638 and $4,933. The tradeoff is visibility and comfort: metal brackets are noticeable, and they can irritate the inside of your cheeks, especially in the first few weeks.
Clear Aligners
Clear aligners like Invisalign use a series of custom-made, removable plastic trays to shift your teeth gradually. Each tray is slightly different, moving your teeth a fraction of a millimeter at a time. Patients consistently rate them higher than braces for comfort and appearance. Average treatment time is around 18 months, about six months shorter than braces.
Aligners work especially well for anterior crowding, closing gaps, correcting rotations, and straightening teeth in cases that don’t require extractions. They tend to keep teeth from tilting outward during alignment, which can be an advantage for certain bite types. They’re also a reasonable choice if you have thin gum tissue, since the gentler force distribution may lower the risk of gum recession.
The limitation is that aligners don’t handle every movement equally well. They’re less effective at torquing roots into position, widening arches significantly, and creating solid contact between upper and lower teeth at the end of treatment. Because the trays cover the biting surfaces of your teeth, they can actually prevent your bite from fully settling. For complex cases involving significant jaw discrepancies, braces give the orthodontist more precise control. Clear aligners typically run $3,250 to $8,250.
Other Braces Options
Ceramic braces work the same way as metal braces but use tooth-colored or clear brackets that blend in more. They cost $3,000 to $8,500. They’re a good middle ground if you want the versatility of fixed braces with less visual impact, though the brackets can stain over time.
Lingual braces are bonded to the back surfaces of your teeth, making them invisible from the front. They’re the most expensive option at $5,000 to $13,000, and they can be uncomfortable against your tongue, especially early on. If you only need one arch treated, single-arch treatment typically costs 60 to 70 percent of the full price, roughly $2,000 to $5,000.
Palate Expanders for Narrow Jaws
If your upper jaw is too narrow, a palate expander can widen it before or alongside braces. The device fits against the roof of your mouth and applies gentle outward pressure on both halves of the upper jaw. Your palate has a seam running down the middle where the left and right sides fuse together, and the expander gradually pushes these halves apart. New bone grows in to fill the gap.
Timing matters a lot with expanders. In children around age 7 or 8, when the palatal seam hasn’t fully hardened, results can come in just one to two months. Starting early can reduce the need for more invasive treatment later. In teenagers and adults, whose bones are fully developed, the same process can take several months to a year or longer.
Jaw Surgery for Skeletal Problems
When misalignment stems from the jawbones themselves rather than just the teeth, braces alone can’t fix the problem. Jaw surgery (orthognathic surgery) repositions the upper jaw, lower jaw, or both. It’s considered when the skeletal discrepancy is severe: a horizontal gap of 5 millimeters or more between upper and lower front teeth, a bite where upper and lower teeth don’t overlap vertically at all (open bite), or facial asymmetry greater than 3 millimeters.
Jaw surgery is also indicated for conditions that go beyond cosmetics, including obstructive sleep apnea caused by jaw position, TMJ disorders resulting from skeletal misalignment, and congenital conditions like cleft lip and palate. Most patients who need jaw surgery also wear braces before and after the procedure to fine-tune the tooth positions once the bones are in the right place.
Veneers as a Cosmetic Shortcut
For mild cosmetic misalignment, porcelain veneers can change the appearance of your teeth without moving them. Veneers are thin shells bonded to the front surface of your teeth, and they can disguise minor crookedness, chips, gaps, and worn-down edges. They don’t change your bite or address the underlying position of your teeth, so they’re only appropriate when the problem is purely visual and mild. If you grind or clench your teeth, veneers aren’t a good fit because the force can crack or chip them.
Retainers: Keeping Your Results
Finishing orthodontic treatment isn’t the end of the process. Teeth naturally tend to drift back toward their original positions, so retainers are essential. There are three main types. Removable Hawley retainers have a wire that sits across the front of your teeth attached to an acrylic plate that rests against the roof of your mouth or behind your lower teeth, costing $150 to $300 per arch. Clear plastic retainers look like thin aligner trays and run $100 to $300 per arch. Fixed retainers are thin wires bonded permanently to the back of your front teeth, costing $250 to $500 per arch.
Fixed retainers do a better job maintaining incisor alignment in the first six months after treatment. Over the long term, though, research shows no significant difference between fixed and removable retainers in maintaining tooth position, arch width, or spacing. The choice often comes down to personal preference and compliance. If you’re likely to forget wearing a removable retainer, a fixed one removes that variable entirely.
