A 100% overbite occurs when the upper front teeth completely cover the lower front teeth when biting down.
Essentially, it's a significant vertical overlap where the bottom teeth are no longer visible. While a slight overbite is considered normal, a 100% overbite is a more severe malocclusion that may require orthodontic intervention. Your orthodontist is the best person to determine the best treatment approach (like Invisalign or braces) if a 100% overbite is present.
