Invisalign for Bottom Teeth Only: Who Qualifies?
Updated September 28, 2026 · Richmond Virginia Orthodontics, Short Pump & Midlothian, VA
Yes, you can get Invisalign for your bottom teeth only. It’s called single-arch treatment, and it works well for some adults. The best candidates have mild crowding, small gaps or a single rotated lower tooth, along with a healthy bite they want to keep. If you have an overbite, underbite or crossbite, or not enough room in your lower front teeth, treating both arches usually gives a safer, better result.
Key Takeaways
- Invisalign can treat bottom teeth only (single-arch treatment) when your bite is healthy.
- Good candidates have mild lower crowding, small gaps, a rotated tooth or relapse after braces.
- Overbites, underbites, crossbites and tight lower spacing usually need both arches treated.
- Many simple bottom-only cases finish in under a year and cost less than full treatment.
We hear this question all the time at Richmond Virginia Orthodontics. Many adults are happy with their upper teeth but notice the bottom teeth crowding or shifting over time. Here’s how to know whether bottom-only Invisalign is right for you.
What Is Single-Arch Invisalign?
Standard Invisalign treats both your upper and lower teeth at the same time. With single-arch Invisalign, you wear aligners on only one arch, in this case your bottom teeth. Your upper teeth stay as they are. We still take a full 3D scan of both arches. Your upper and lower teeth have to fit together precisely, and we need to plan the lower movements around your bite.

Who Is a Good Candidate for Bottom Teeth Only?
You may be a good fit for lower-only Invisalign if:
- Your lower front teeth are mildly crowded or slightly crooked
- You have small gaps between your bottom teeth
- One or two lower teeth are rotated or out of line
- Your teeth shifted after braces because you stopped wearing a retainer
- Your bite is already healthy, and you’re happy with your upper teeth
When You’ll Need Both Arches Treated
Are you a candidate for bottom-only Invisalign?
Are you a candidate for bottom-only Invisalign?Bottom-only treatment isn’t safe for every smile. We’ll recommend treating both arches if:
- You have an overbite, underbite, crossbite or open bite
- There isn’t enough room to straighten your lower front teeth without pushing them against your upper teeth
- Your upper and lower teeth need to meet differently
- Your lower teeth have moved in a way that changed your bite
Your bite is a precise relationship. Moving only the bottom teeth when the bite needs correcting can cause uneven contact, tooth wear or jaw discomfort. That’s why an in-person orthodontic exam matters so much. It’s also why we don’t recommend do-it-yourself aligners.

Why Lower Teeth Shift in Adults
Lower front teeth are the most likely to crowd as we age. Natural changes in the jaw, the pressure of chewing and, for former braces patients, not wearing a retainer all play a role. It’s so common that we wrote a full guide on teeth shifting after age 40. The good news is that mild lower crowding is often one of the quickest problems to fix.
Benefits of Bottom-Only Invisalign
- Nearly invisible: clear aligners are hard to spot, especially on the lower teeth.
- Removable: no food restrictions, and you can brush and floss normally.
- Comfortable: no brackets or wires.
- Often faster: simple lower-only cases often finish in under a year.
- Focused: we treat only the teeth that need it.
How Long Does Bottom-Only Invisalign Take?
It depends on how much your teeth need to move. Many simple lower-arch cases finish in under a year, and minor touch-ups can be quicker. As with any Invisalign treatment, you’ll wear your aligners 20 to 22 hours a day. Then you’ll wear a retainer to keep your lower teeth from drifting again.
Is Bottom-Only Invisalign Cheaper?
Treating one arch is often less expensive than treating both, because fewer aligners and less treatment time are usually involved. Your exact fee depends on your case. We’ll give you a clear, itemized fee at your exam, and we work with many dental insurance plans that include orthodontic benefits.

Bottom Teeth Invisalign FAQs
Can you get Invisalign for bottom teeth only?
Yes. Single-arch Invisalign can treat only your bottom teeth if your bite is healthy and your lower teeth have mild crowding, gaps or rotations. An orthodontist exam confirms whether it’s safe for you.
Will fixing only my bottom teeth change my bite?
It can if the case isn’t planned carefully. That’s why we scan both arches and plan lower movements around how your teeth fit together.
How long does Invisalign take for just bottom teeth?
Many simple bottom-only cases finish in under a year. We’ll give you your exact timeline after your exam.
Do I need a retainer after bottom-only Invisalign?
Yes. Lower teeth are the most likely to shift again, so wearing your retainer protects your results.
