Understanding Overbite
What is an Overbite?
An overbite refers to the vertical overlap of the upper front teeth over the lower front teeth. A slight
overlap is considered normal and helps protect your teeth while chewing. However, when the overlap becomes
excessive, it can create both cosmetic and functional problems.
People often confuse an overbite with "buck teeth." While protruding teeth may occur with an overbite, they
are not always the same condition. An orthodontist performs a detailed clinical examination to determine the
exact type and severity of your bite problem.
Root Causes
What Causes an Overbite?
Several factors contribute to the development of an overbite, including:
- Genetics: Many people inherit jaw size and tooth alignment traits from their parents.
- Childhood Habits: Thumb sucking, prolonged pacifier use, tongue thrusting, or nail
biting during early growth.
- Tooth Loss: Missing teeth without timely replacement can cause adjacent teeth to shift,
altering bite alignment.
- Jaw Growth Problems: Discrepancies in the growth rates of the upper or lower jaw.
- Teeth Crowding: Lack of dental arch space can push teeth into positions that alter the
bite.
