The PM4 tooth, or primary molar 4, refers to a specific type of primary (deciduous) tooth in children, typically located in the back of the mouth. It is one of the molars that help with chewing and grinding food. Primary molars are crucial for the development of a child's dental structure and are usually replaced by permanent molars around the age of 10 to 12 years. The PM4 is important for maintaining space for the eruption of permanent teeth.
