A deep bite, also known as a deep overbite, is a dental misalignment in which the upper front teeth overlap the lower front teeth to an unusual extent. In a normal bite, the upper front teeth cover about a third of the lower front teeth; the overlap is much more significant in a deep bite.
The causes of a deep bite can be varied. There is often a genetic predisposition, but factors such as tooth growth patterns, the loss of molars leading to overloading of the front teeth, or certain oral habits in childhood can also contribute.
A deep bite can cause various problems. It can cause increased wear on the teeth, especially the front teeth, damaging the periodontium, tooth enamel, and other dental issues over time. It can also cause jaw joint pain and difficulty biting and chewing.
Diagnosis and treatment:
Diagnosis of an overbite is usually made through a clinical examination supplemented by X-rays. Treatment depends on the patient’s age and the severity of the deformity. In many cases, orthodontic treatment involves braces or special appliances. In severe cases or combination with severe functional disorders (e.g. obstructive sleep apnea), jaw surgical correction may be necessary.
The aim of treating deep bites is to restore the correct relationship between the teeth of the upper and lower jaw, reduce wear on the dentition and improve jaw function. Early detection and treatment are crucial to avoid long-term damage and ensure optimal function and aesthetics.
