An overbite is a dental condition where the upper front teeth overlap the lower front teeth when the mouth is closed. This misalignment can occur due to various factors, including genetics, thumb sucking, or prolonged use of pacifiers during childhood. An overbite is measured in percentage, with a normal range being around 2-4 millimeters. While a mild overbite may not cause significant issues, a severe overbite can lead to problems such as jaw pain, difficulty chewing, and increased wear on teeth. Treatment options for an overbite often include braces or other orthodontic devices to help realign the teeth and improve overall dental health.
