An underbite isn't just a matter of dental or physical health; it significantly influences one's appearance too. It occurs when the lower teeth extend outward past the upper teeth, resulting in a misalignment of the jaws.

Beyond the aesthetic concerns, underbites can lead to functional issues, such as difficulty with speech, biting, and chewing. They may also cause jaw pain and discomfort.
