How Invisalign Helps Correct an Underbite

Invisalign corrects an underbite by using a series of custom-engineered plastic trays that apply strategic pressure to the upper and lower arches. To successfully move the lower teeth back or the upper teeth forward, Pete Higgins, DDS often incorporates “attachments”—small, tooth-colored dots bonded to the teeth—that allow the aligners to grip more effectively.

In many underbite cases, elastics (rubber bands) are used in conjunction with the aligners. These bands connect the upper and lower trays, providing the continuous tension necessary to shift the entire dental arch. This dual-action approach helps to “jump the bite,” moving the upper teeth into their proper position slightly in front of the lower teeth, resulting in a more harmonious dental relationship.

Invisalign is an excellent option for adults with mild to moderate underbites. Unlike children, whose jawbones are still growing and more easily manipulated, adult jawbones are fully developed. However, as long as the underbite is “dental” (caused by tooth positioning) rather than purely “skeletal” (caused by severe jaw bone discrepancy), Invisalign can achieve remarkable results.

Adults often prefer Invisalign because it is virtually invisible and fits into a professional lifestyle. Pete Higgins, DDS focuses on creating a stable, functional bite that reduces the risk of excessive tooth wear and TMJ (jaw joint) disorders, which are common complications for adults living with untreated underbites.

The timeline for correcting an underbite typically ranges from 12 to 24 months. Because underbite correction involves moving the entire arch of teeth rather than just straightening a few crooked ones, it often requires a longer commitment than simple spacing or crowding cases.

The total duration depends on the severity of the malocclusion and patient compliance. Wearing the aligners for the recommended 22 hours per day is critical. During your progress checks at Four Corners Dental Group, we monitor the movement of your jaw and teeth to ensure the bite is transitioning safely and efficiently, adjusting your custom plan as needed to keep your treatment on track.

Yes, Invisalign is designed to address both the appearance of your smile and the underlying function of your bite. From a cosmetic standpoint, correcting an underbite can soften a prominent chin and improve the overall symmetry of the lower face.

Functionally, resolving an underbite is vital for long-term health. When the teeth don’t align, it can cause difficulty chewing certain foods, speech impediments (such as lisps), and increased strain on the jaw muscles. By aligning the teeth correctly, Invisalign helps distribute biting forces evenly, protecting your tooth enamel from premature chipping and reducing the likelihood of periodontal issues.
