Is It Possible to Straighten Only One Arch of Teeth?

Modern orthodontic treatments like Invisalign clear aligners have truly changed what it means to straighten your smile. They’re excellent for minor and moderate dental concerns, which is why many people experiencing seemingly small issues like overlapping teeth opt for this treatment. In fact, many patients who are only looking to fix one arch of their teeth often wonder whether they would be a good candidate for Invisalign treatment. The truth is, this scenario highlights a little bit of a gray space in the dental world, and dentists may only agree to do this on a case-by-case basis. Read on to learn why.

Can You Straighten Only One Row of Teeth?

While straightening only one row of your teeth with Invisalign clear aligners is possible, it’s certainly not the norm. Most dentists recommend straightening both rows of your teeth at the same time in order to prevent possible complications down the road, like a misaligned bite. However, some patients, and dentists, may only see that a single row of teeth need to be straightened, like making sure that two overlapping teeth on the bottom arch get straightened out. In these situations, depending on the circumstances and a thorough consultation with a dentist, they may recommend using only one Invisalign tray instead of two throughout your treatment.

When is Single-Arch Invisalign Treatment Most Effective?

The gray space of single-arch Invisalign treatment is that orthodontics can be either functional, cosmetic, or a little bit of both in nature. If your Invisalign treatment is designed to address purely cosmetic concerns, it’s more likely that single-arch orthodontics could be effective for you. In certain functional situations as well, like for patients with minor overbites or underbites, single-arch treatment may also be beneficial if you’re happy with the alignment of your other teeth.

During your consultation with your dentist, you can voice your concerns and desire for single-arch orthodontics to them. Based on their evaluation of your orthodontic issues, they may determine that you’re a great candidate for this method, or not, and they can explain why.

What are Some Possible Complications of Single-Arch Orthodontics?

Straightening one arch of teeth with Invisalign isn’t a common treatment plan because the risk of complications after your treatment can be higher. When you begin shifting only one arch of teeth and leave the other untouched, it could cause bite misalignment or uneven wear-and-tear on your teeth. It can also put you at an increased risk of developing TMJ disorder by changing the way that your teeth fit together.

While single-arch orthodontics may sound like the most convenient, affordable, and reasonable option, you may be surprised to learn from your dentist that’s just not the case in your situation. The best way to tell whether this treatment approach is right for you is to schedule a consultation with your Invisalign dentist in Westport.
