Posterior Teeth

Posterior teeth are the premolars and molars located toward the back of the mouth. They have broader chewing surfaces with multiple cusps and often more complex root structures compared with front teeth, which makes them well suited for grinding and crushing food; wisdom teeth (third molars) are also classified as posterior teeth and may erupt later in life or cause crowding and other issues.

Because posterior teeth have deep grooves and contact food directly, they are commonly affected by tooth decay, fractures and wear, and they can be involved in periodontal (gum) disease; treatment options include fillings, inlays and onlays, crowns, root canal treatment, or extraction followed by a bridge or implant when necessary. Good care for posterior teeth involves thorough brushing, interdental cleaning (floss or interdental brushes), topical fluoride or sealants when appropriate, and regular dental examinations to detect problems early and preserve chewing function.
