Occlusion

Occlusion is the term dentists use to describe the way the upper and lower teeth come together during biting and chewing. It covers both the static contacts between teeth when the jaws are closed and the dynamic relationships during jaw movement, and a well-aligned occlusion helps distribute chewing forces evenly, protecting teeth and supporting comfortable function.

When occlusion is out of alignment—often called malocclusion—patients may experience symptoms such as uneven tooth wear, sensitivity, difficulty chewing, jaw muscle strain, headaches, or temporomandibular joint (TMJ) pain. Dentists evaluate occlusion by clinical examination and sometimes imaging, and management can include restorative treatments (crowns, inlays/onlays, implants), occlusal adjustment or splint therapy, orthodontic treatment, or night guards to address the specific cause and reduce symptoms.
