Overbite, Underbite, and Crossbite – Diagnosis & Treatment in Basingstoke
A healthy smile is not just about straight teeth; it is also about how your upper and lower teeth meet when you close your mouth. Bite misalignments (malocclusions) such as overbites, underbites, and crossbites can cause uneven tooth wear, jaw pain, chewing difficulties, and cosmetic self-consciousness.
Understanding Bite Issues (Malocclusions)
Bite issues occur when the teeth or jawbones do not align properly. They can develop naturally during childhood development, or as a result of habits such as thumb sucking, prolonged pacifier use, or genetics.

Overbite (Deep Bite)
An overbite occurs when the upper front teeth extend too far over the lower front teeth. While a slight overlap of 1–2mm is normal, a deep overbite can cause the lower teeth to bite into the roof of the mouth, leading to gum irritation, enamel wear, and jaw strain.

Underbite & Crossbite
An underbite occurs when the lower jaw and teeth extend forward ahead of the upper teeth, creating a pronounced lower jaw profile. A crossbite happens when some upper teeth bite inside the lower teeth rather than outside, causing asymmetrical jaw growth and uneven wear.
