Braces for bottom teeth only typically cost between $3,000 and $7,000, depending on the type of braces you choose and the complexity of your case. That’s roughly 40% to 60% less than full-mouth orthodontic treatment, though the discount isn’t always as steep as you might expect. Many of the fixed costs of orthodontic care, like imaging, office visits, and treatment planning, apply whether you’re treating one arch or two.
Cost by Type of Braces
The type of braces you select is the single biggest factor in what you’ll pay. Traditional metal braces on the bottom arch alone generally fall in the $3,000 to $5,000 range. Ceramic braces, which use tooth-colored brackets that blend in more, tend to run $500 to $1,500 higher than metal for the same treatment. Lingual braces, which are bonded to the back of your teeth and completely hidden from view, are the most expensive option, often reaching $5,000 to $7,000 or more for a single arch.
Clear aligners are another popular choice for lower teeth. Companies like Invisalign typically charge $3,000 to $5,000 for single-arch treatment, though some direct-to-consumer aligner brands advertise prices starting around $2,000. The trade-off with budget aligners is that they’re generally suited only for mild to moderate crowding and come with less hands-on oversight from an orthodontist.
Why Single-Arch Treatment Isn’t Half the Price
It’s natural to assume that treating one arch should cost about half as much as treating both. In practice, orthodontists price single-arch cases at a smaller discount because much of the work is the same regardless of how many teeth are involved. Your initial consultation, X-rays, 3D scans, and custom treatment plan take the same amount of time and expertise whether you need braces on six teeth or twenty-six. You’ll also attend roughly the same number of adjustment appointments over the course of treatment.
The materials themselves, brackets and wires or aligner trays, are actually a small fraction of the total bill. Most of what you’re paying for is the orthodontist’s diagnostic skill, chair time, and ongoing monitoring. That’s why single-arch braces typically cost 40% to 60% of full treatment rather than a clean 50%.
What Drives the Price Up or Down
Several factors can push your quote toward the higher or lower end of these ranges.
Severity of misalignment matters most. Mild crowding or a single rotated tooth is a simpler fix that requires fewer appointments and shorter treatment time. Severe overcrowding, significant spacing, or bite issues that affect how your top and bottom teeth meet can add procedures, specialized appliances, or extra months of treatment, all of which increase cost.
Where you live also plays a role. Orthodontic fees reflect local cost of living and office overhead. Practices in major metro areas or affluent neighborhoods routinely charge more than those in suburban or rural locations. The difference can easily be $1,000 or more for the same type of treatment. If you’re near a city border, it’s worth getting quotes from offices in neighboring areas.
The orthodontist’s experience level factors in as well. A board-certified specialist with decades of practice may charge a premium over a general dentist who offers orthodontic services. That premium often comes with more precise treatment planning, which can mean fewer complications and a shorter overall timeline.
Insurance and Payment Options
Dental insurance plans that include orthodontic benefits usually cover a portion of the cost, often with a lifetime maximum of $1,000 to $2,000 for braces. Coverage is more common for dependents under 18. Adult orthodontic coverage exists but tends to be more limited. Whether your plan covers single-arch treatment at the same rate as full treatment varies by insurer, so it’s worth calling your plan before your consultation to ask specifically about partial orthodontic work.
Most orthodontic offices offer in-house payment plans that spread the cost over the length of treatment, typically 12 to 24 months, often with no interest. Some practices also accept third-party financing through companies like CareCredit. If you have a flexible spending account or health savings account through your employer, orthodontic expenses generally qualify, which effectively gives you a discount equal to your tax rate.
How Long Treatment Takes
Bottom-only braces typically take 6 to 18 months, shorter than the 18 to 36 months common with full-mouth treatment. Mild crowding or minor spacing can sometimes be resolved in as little as six months. More complex cases involving significant tooth movement or bite correction take closer to a year and a half. Your orthodontist will give you a timeline estimate at your first appointment, though actual duration depends on how your teeth respond and whether you follow care instructions consistently.
Retainer Costs After Treatment
Braces are only half the investment. Once your bottom teeth are aligned, you’ll need a retainer to keep them in place. Without one, teeth gradually drift back toward their original positions, especially in the lower arch where crowding tends to recur.
A permanent retainer is a thin wire bonded to the back of your lower front teeth. Placement typically costs $150 to $500, though some orthodontists include it in the overall treatment fee. Permanent retainers are low-maintenance and work around the clock, but they do require careful flossing and occasional repair if the wire loosens or breaks.
Removable retainers, either the clear plastic tray style or the traditional wire-and-acrylic type, generally cost $100 to $300 per set. You’ll typically wear them full-time for the first few months after braces come off, then transition to nighttime-only wear. They need to be replaced periodically as they wear out or if they’re lost.
Is Single-Arch Treatment Right for You
Not everyone who wants braces on just the bottom teeth is a good candidate for single-arch treatment. Your orthodontist will evaluate how your upper and lower teeth fit together when you bite down. If straightening the bottom arch alone would create a bite that doesn’t align properly, you may need treatment on both arches to get a stable, functional result. In some cases, what looks like a bottom-teeth problem is actually a mismatch between arches that requires a full treatment plan.
If your top teeth are already well-aligned and your bite is healthy, single-arch treatment can be a cost-effective way to fix crowding, spacing, or rotation on the bottom. The best way to find out is to schedule consultations with two or three orthodontists. Most offer free or low-cost initial evaluations, and comparing treatment plans side by side gives you a clearer picture of both the clinical recommendation and the price.
