Acquire molars is a term used to describe the process of growing and developing adult teeth. It is the final stage of tooth development, which begins with the eruption of baby teeth and ends with the emergence of permanent teeth. The term acquire molars is derived from the Latin word 'molare' which means 'to grind'. The process of acquiring molars usually begins around the age of six and is completed by the age of twelve. During this period, the primary teeth are gradually replaced by the permanent teeth.
