At first glance, getting braces on only your upper or lower teeth can seem like an appealing idea. It may appear easier, more cost-effective, and less noticeable than full treatment. But although single-arch braces are possible in very select cases, orthodontists rarely recommend them. That’s because your smile doesn’t just rely on straight teeth—it depends on how both arches work together.
Below, you’ll learn why treating only one dental arch can lead to complications, when it might be appropriate, and what your orthodontist will consider when planning the best approach for your smile.
Why Orthodontists Usually Avoid Single-Arch Braces
Traditional braces work by gradually shifting your teeth and jaw into better alignment. While it’s true that crooked or crowded teeth can exist in just one arch, the bite relationship between your top and bottom teeth is part of nearly every treatment plan. If only one arch is moved, it can disrupt this delicate balance.
For example, aligning bottom teeth without adjusting the top may cause them to collide improperly when you bite. Likewise, straightening top teeth alone can create spacing or bite problems that weren’t there before. Many patients who try to treat only one arch eventually develop issues such as increased overbite, underbite, or uneven wear on the enamel. Correcting these problems often requires additional treatment, which can extend the timeline and cost.
When Single-Arch Braces Might Be an Option
Although rare, there are situations where an orthodontist may approve braces on just the top or bottom teeth. This is usually limited to very mild cosmetic concerns where the patient already has a healthy, balanced bite.
If the bite is stable, the arches are well-matched, and the misalignment is minor, single-arch treatment may be considered. Even then, orthodontists proceed cautiously, monitoring the bite closely throughout the process. In most cases, a full evaluation reveals that both arches will benefit from treatment, even if one appears more visibly misaligned.
What Your Orthodontist Evaluates Before Making a Recommendation
Before deciding whether single-arch braces are appropriate, your orthodontist will assess several key factors. These include your bite relationship, the position of your jaw, the degree of tooth misalignment, and the amount of space available. They’ll also consider how your teeth will interact once they begin moving.
Your provider may use X-rays, digital scans, and photographs to map out these details and simulate how different treatment options will affect your smile. Because the goal is not just straight teeth, but a functional and comfortable bite, most orthodontists lean toward full-arch treatment whenever possible.
The Bottom Line
While traditional braces on just your top or bottom teeth may seem convenient, they aren’t the ideal choice for most patients. Full-arch treatment ensures better bite harmony and long-lasting results.
A brief consultation with your orthodontist is the best way to learn which option will help you achieve a healthier, more confident smile.
