Some vertical overlap between upper and lower front teeth is normal. When that overlap is excessive, the bite may be described as deep. People sometimes use “overbite” to mean upper teeth that project forward, but that horizontal relationship is called overjet. The distinction matters because the movements and treatment goals can be different, even when both features occur together.
At Cookstown Dental Centre, we assess the amount of overlap, how the teeth contact, and whether there are associated concerns such as wear or tissue contact. The examination also considers the broader dental and jaw relationship. Treatment is based on the findings and your goals rather than a label alone. Some cases can be considered for orthodontic correction, while more complex relationships may benefit from specialist assessment and a discussion of the limits of a tooth-only approach.
