Underbites are one of the most underdiagnosed orthodontic conditions in kids. An underbite is when the lower jaw protrudes forward so that the lower teeth sit in front of the upper teeth when biting down. It affects chewing, speech, facial balance, and jaw health over time. Here is the important part: underbites are significantly easier to correct in children whose jaws are still growing. Waiting until adulthood often means more complex treatment. If your child's lower jaw seems to stick out, get it evaluated now.
