Most of the time, having crooked teeth or a malocclusion (bad bite) can be traced to genetics.Other malocclusions stem from environmental factors.Below are examples of some common orthodontic problems in teens and adults.If you think you have one of these orthodontic problems, make an appointment to see an orthodontist to find out how the problem can be corrected.
Excessive horizontal overlap of the front teeth. The technical term for overbite is “overjet.”
Lower front teeth biting in front of the upper front teeth.
Anterior (Front) Crossbite
Lower front teeth biting in front of the upper front teeth. This can involve two teeth or groups of teeth.
Posterior (Back) Crossbite
Upper back teeth biting inside of lower back teeth. This can involve two teeth or groups of teeth.
No overlap of the upper and lower front teeth when biting.
Excessive vertical overlap of the upper and lower front teeth when biting.
Misalignment of teeth caused by lack of space.
Spacing between teeth usually caused by small or missing teeth or a strong tongue pushing the teeth forward.
In some patients, some adult teeth never develop. The most common missing teeth are the lower second premolars (directly in front of the first permanent molars), upper lateral incisors, and third molars (wisdom teeth).
Thumbsucking, fingersucking, tongue sucking, tongue thrusting, and nail biting can lead to problems such as open bites and large “overbites.”
