Molars
Molars
Molars (/ˈmoʊ.lərz/) are the rearmost and most complicated kind of tooth in most mammals. They are used primarily to grind food during chewing. The name is derived from Latin, molaris dens, meaning "millstone tooth", from mola, millstone and dens, tooth. Molars are generally larger, broader and more robust than the premolars.
Etymology
The term "molar" comes from the Latin molaris dens, meaning "millstone tooth", due to its flat, grinding surface. The Latin word mola means "millstone", while dens means "tooth".
Types of Molars
There are three types of molars: the first, second, and third molars. The third molars are commonly referred to as wisdom teeth.

- Second Molars: Also known as twelve-year molars, these usually erupt around the age of twelve.
- Third Molars: Commonly known as wisdom teeth, these are the last teeth to erupt, usually between the ages of seventeen and twenty-five.
