I Only Want Braces on My Top Teeth


“I only want braces on top teeth. No one sees my bottom teeth anyway.” This is a common request, especially with all the recent buzz about Six Month Smiles and "direct-to-consumer" aligners. Is single arch treatment good treatment?

One-arch treatment is possible and gives excellent results in some patients. The success of one-arch treatment is determined by the starting position of the teeth in both arches and the way they are related to each other (the bite). Any time you align teeth that are crowded, they tend to move forward. This is a wonderful thing if the upper teeth are behind the lower ones (crossbite). If the bite is good in the back but the lower teeth are crowded, aligning only the upper teeth will create an “overbite” that wasn’t there before. This might be a compromise that you are willing to accept to avoid bottom braces; you just need to be aware of how it will turn out before you get started. If you have a little overbite at the beginning of treatment, you should plan on it getting bigger if you only treat the top arch.

In some cases, it is possible to reduce the amount of upper arch flaring by reducing the size of the upper teeth during treatment. Known as InterProximal Reduction (IPR), Air Rotor Stripping (ARS), or slenderizing, this is an option that you should discuss with your orthodontist. IPR can be a useful procedure in the right cases, but it is not advisable in everyone.

Braces in the upper arch only can be an excellent treatment in cases where there is space between the upper teeth at the start of treatment, especially if there is an overbite. Closing spaces between the front teeth tends to move the teeth backwards reducing the amount of overbite. In this case, single arch treatment is able to address both conditions at the same time. As long as you are happy with your bottom teeth exactly as they are, single arch treatment in this case is the treatment of choice.

In smiles where the lower teeth look good, there is no overbite, and there are spaces between the upper teeth, the problem may be with the size of the teeth themselves. In these cases, there are a couple of options. Since closing all the space will move the front teeth backwards, doing so is not an option if the bite is good. Instead, we could use the braces to move the front teeth that people see together and move the spaces where they are more hidden. The other option is to have your dentist close the extra space by adding “enamel” (bonding) between the teeth either where they are now or after we line them up. Building up narrow teeth not only makes them look nicer, it will also give you a more stable result.
