Can Orthodontic Expanders be used on the Lower Teeth to Avoid Extractions?

An orthodontic expander, also commonly referred to as a “palate-widening device,” is commonly used on the top teeth to create space in between the teeth. The device, which is secured around one tooth on each side of the top of the mouth, gradually creates space in the top of the teeth through the course of a few weeks or months. By spacing out the palate, the teeth have more room to shift, which is ideal for patients who plan to get braces. Because the orthodontic expanders create more room at the top of the teeth, it lowers the chances of needing to extract teeth as a method of creating space as well. Since orthodontic expanders are successfully used to create room on the upper teeth, can’t the same method be used to resolve crowding with the bottom?

An orthodontist is able to use an expander device on the upper teeth because of the mid-palatal suture in the upper arch of our mouths. The palate can be expanded if there is soft cartilage in the suture. Each time the expander is activated, either at home or by an orthodontist specialist, a gap between the front teeth develops as the teeth space out. But when an expander is used on the lower arch of the teeth, there is no such suture, which doesn’t allow them the chance to expand.
