Half the Aligners, All the Results? One-Arch Invisalign Explained

If your lower teeth are straight but your upper teeth could use some work, you might be wondering if you can focus your Invisalign treatment. Well, you can! This is often referred to as “single arch” Invisalign treatment. However, there’s more to it than simply wearing one tray at a time. Continue reading to learn about how single-arch Invisalign treatment works and if it might be right for you.

How Does Single Arch Invisalign Treatment Work?

Single-arch Invisalign uses aligners on only one dental arch—either top or bottom. It’s most commonly used for minor spacing, crowding, or cosmetic adjustments in upper front teeth. If your lower teeth are perfectly aligned and don’t affect your bite, your dentist may approve a top-only treatment, or vice versa.

When Would Single Arch Treatment Be Best?

Single arch Invisalign could be a great option if:

  • Your teeth on one arch are already well-aligned
  • You only need small cosmetic changes
  • Your bite (how your teeth come together) isn’t affected by the suggested changes
  • You’re looking for a shorter, more affordable treatment plan

Your dentist will evaluate your bite, jaw alignment, and discuss your goals to make sure one-arch Invisalign won’t create future problems. Once your consultation is over, you should have a much better idea of the potential risks and benefits of your treatment.

When Would Single Arch Invisalign Be a Risk?

If your bite is off, even slightly, treating just your top or bottom teeth might make things worse. Aligners shift teeth with precision, but moving one set without adjusting the other can cause misalignment, jaw strain, or uneven wear.

For example, fixing crowding on the top without adjusting the bottom may cause your pearly whites to collide in new, uncomfortable ways. Over time, this can lead to broken or cracked enamel, jaw pain, and worn-down teeth.

Why You Need a Professional Opinion

Invisalign is for more than just looks, it’s a treatment that can improve your health. So, while it might sound simple to treat one row of teeth, your dentist will need to assess your entire mouth to ensure long-term success.

The good news? If you’re a candidate, single-arch Invisalign can be faster, more affordable, and just as effective as full treatment!

Invisalign for single arch use is possible, but it’s not for everyone. The best way to know for sure is to book a consultation with your dentist. They’ll help you weigh your options and build a plan that gets your smile where you want it to be without risking your bite.
