Can You Get Braces on Only One Arch?
The short answer is yes — single-arch braces are possible and more common than you might think. About 10-15% of orthodontic patients receive treatment on only the upper or lower teeth. However, just because it is possible does not mean it is the best option for everyone. Your bite is a complex system where the upper and lower teeth need to work together, and treating only one arch can sometimes create new problems.
Single-arch braces work best for mild crowding or spacing issues when your bite is already well-aligned. If you have a bite problem (overbite, underbite, crossbite), you will likely need both arches treated.
When Single-Arch Treatment Works
Your orthodontist may recommend single-arch braces when the issue is isolated to one arch and your bite alignment is already good. Here are the most common scenarios:
- Minor crowding on one archSlight overlapping of front teeth on either the top or bottom, while the other arch is straight.
- Small gaps between teethA space from a missing tooth or natural gaps that only affect one arch.
- Relapse from previous treatmentTeeth that shifted after braces because you stopped wearing your retainer — often just one arch has moved.
- Cosmetic concerns onlyWhen the issue is purely aesthetic and your bite functions normally.
When You Need Both Arches
Most orthodontic issues involve the relationship between your upper and lower teeth. Treating only one arch when both need work can make your bite worse, leading to jaw pain, uneven wear, or difficulty chewing.
- Overbite or underbite — these are bite problems that require both arches to correct
- Crossbite — upper teeth sitting inside lower teeth needs full treatment
- Significant crowding on both arches — straightening one while the other is crooked leaves an uneven result
- Midline shift — when the center of your upper and lower teeth do not align
