Dental occlusion refers to the way teeth align and come together when the mouth is closed. It involves the contact between upper and lower teeth, which is essential for proper chewing and speaking. A healthy occlusion allows for even distribution of bite forces and helps maintain the overall health of the jaw and teeth. Problems with dental occlusion, known as malocclusion, can lead to issues such as tooth wear, jaw pain, and difficulty in chewing. Common types of malocclusion include overbite, underbite, and crossbite. Proper assessment and treatment by a dentist can help correct these issues and improve oral function.
