Invisalign for just the bottom teeth typically costs between $1,500 and $4,500, depending on how much correction your teeth need. That’s noticeably less than full two-arch treatment, which often runs $3,000 to $8,000. The lower price reflects fewer aligners, fewer office visits, and a shorter treatment timeline.
What Determines the Final Price
The biggest factor in your cost is complexity. Invisalign offers different product tiers based on how many aligners you’ll need, and single-arch cases for the bottom teeth usually fall into one of two categories.
The Express tier runs $1,500 to $3,000 and is designed for minor corrections: a single tooth that’s drifted, small gaps, or slight crowding in the front. These cases use fewer aligners and wrap up quickly. The Lite tier runs $3,000 to $4,500 and handles moderate crowding or spacing that requires more stages of movement. Your orthodontist or dentist will determine which tier fits your situation after scanning your teeth.
Geography matters too. Providers in major metro areas tend to charge more than those in smaller cities, and pricing varies from office to office even within the same zip code. Some practices bundle all visits and retainers into a single quote, while others charge for those separately.
Who Qualifies for Bottom Teeth Only
Single-arch Invisalign works best for cosmetic issues that don’t affect how your upper and lower teeth fit together. Good candidates typically have minor gaps between bottom teeth, slightly crooked front teeth, a single tooth drifting out of alignment, or dental drift that happened after previous orthodontic treatment (like not wearing a retainer after braces).
If your bite is involved, single-arch treatment probably won’t work. Overbites, underbites, crossbites, and open bites require both arches to move in coordination. Shifting only the bottom teeth when there’s a bite problem can actually make things worse, creating new contact points that wear down enamel unevenly. Your provider will evaluate your bite before approving a single-arch plan, and not everyone who wants bottom-only treatment will be a candidate for it.
Treatment Timeline
Most bottom-only cases finish in 6 to 9 months. Simpler corrections on the Express tier can wrap up even faster, sometimes in as little as 3 to 4 months. The timeline depends on how far your teeth need to move and how consistently you wear the aligners. Invisalign requires 20 to 22 hours of daily wear to stay on schedule. Taking them out too often is the most common reason treatment drags past the original estimate.
Insurance and Payment Options
Dental insurance that includes orthodontic coverage will generally apply to Invisalign, including single-arch treatment. The average orthodontic insurance benefit is about $1,772, with most plans capping out at $2,000 to $3,000. On a $2,000 bottom-only case, that coverage could cut your out-of-pocket cost in half or more.
Major carriers like Delta Dental, MetLife, Cigna, and Humana all have plans that cover Invisalign, though specifics vary. Cigna’s Dental 1500 plan, for example, includes a $1,000 orthodontic benefit. Delta Dental covers Invisalign as a standard benefit on any plan with orthodontic coverage. Check your specific plan’s orthodontic benefit and lifetime maximum before assuming coverage.
Most orthodontic offices also offer monthly payment plans, often interest-free for 12 to 24 months. Some accept health savings account (HSA) or flexible spending account (FSA) funds, which let you pay with pre-tax dollars. For a $2,000 treatment on a 12-month plan, you’d pay roughly $165 per month before any insurance kicks in.
Costs That Come After Treatment
The price of Invisalign doesn’t always include retainers, and you will need one. Teeth naturally drift back toward their original positions after treatment, especially in the first year. Invisalign’s branded retainer (Vivera) costs $300 to $600 for a single arch, though many offices only sell them as a full set covering both arches. Some providers include the first retainer in your treatment fee, so ask before you start.
You’ll also need to replace retainers periodically. They wear out, crack, or stop fitting well over time. Budget for a replacement every one to two years if you’re using clear retainers. Permanent bonded retainers (a thin wire glued behind your bottom teeth) are another option that eliminates the replacement cycle, though they require occasional maintenance if the bond loosens.
How to Get an Accurate Quote
Online estimates can only get you so far because pricing depends on your specific teeth. The most reliable way to get a number is to book a consultation, which most Invisalign providers offer for free or at low cost. During that visit, the provider will scan your teeth, assess whether single-arch treatment is appropriate, and give you a breakdown that includes the treatment tier, number of aligners, office visits, and whether retainers are included. Getting quotes from two or three offices in your area gives you a realistic range and some leverage to negotiate.
