How many roots do all upper molars have?

All upper molars generally have three roots. These roots consist of two buccal roots (mesiobuccal and distobuccal) and one palatal root. This anatomical configuration allows upper molars to effectively anchor the teeth in the upper jaw and to possess the necessary strength for chewing and grinding food.

Each root houses one or more root canals, where the pulp is located, and this configuration helps accommodate the larger size and multiple cusps found on upper molars compared to other teeth. The three-root structure is a distinguishing characteristic of upper molars, setting them apart from different types of teeth in the mouth, such as lower molars, which typically have two roots, or other single-rooted teeth like incisors. Understanding this anatomical detail is essential for recognizing the differences in dental procedures that may involve upper molars.
