What is the difference between and openbite and an overjet?

Open verses over: An openbite generally is where the upper and lower anterior teeth do not overlap, i.e. If you can put your tongue between your anterior teeth with your upper and lower back teeth closed. An overjet is the distance the upper front teeth are out in front of the lower front teeth, i.e. "buck teeth" would be considered a severe overjet.

See answer below: Overjet is the horizontal distance between the upper and lower jaw when the teeth are in occlusion. An open bite is when the back teeth are closed and there is an "open distance " between the front teeth.

Open bite = upper front teeth do not overlap lower. They should overlap slightly, creating a normal 2mm overbite. Overjet is measure of the horizontal distance between the biting edge of upper front teeth when measured to the front surface of lower front teeth, again about 2mm. if your. teeth don't measure up, see a specialist Orthodontist for Examination.
