It has two bicuspids on the top and two on the bottom, on each side of the mouth (a total of eight). The bicuspids have a flat surface with ridges to help shred food.
Then come the bicuspids or premolars.
There are eight bicuspids, four in the upper arch and four in the lower arch. Larger than incisors and canines, but smaller than molars, bicuspids have a flatter upper surface with several crests that are used to grind food into smaller pieces.Bicuspids don't appear in humans until age 10, which means that there is only one set of bicuspids that are permanent teeth. In adult dentition (the second set of teeth), the 8 primary molars are replaced by premolar (or bicuspid) teeth. The 12 adult molars sprout (grow on the gums) behind the primary teeth and do not replace any, for a total of 32 teeth. The eight bicuspid teeth, also known as premolars, are located between the canines and molars in both the upper and lower jaws.
These teeth are larger than incisors and canines, but smaller than molars. They have a flat surface with ridges that help to shred food into smaller pieces. Bicuspids don't appear until age 10, meaning that there is only one set of permanent bicuspids. The protrusions on these teeth are actually cusps, raised areas that facilitate the shredding of food, as well as pits and furrows. Bicuspid teeth are essential for breaking down food particles before they reach the molars.
In adult dentition, there are four incisors, two canines, four premolars (or bicuspids), four molars, and two wisdom teeth (also called third molars) in each mandible. It's important to take care of your bicuspid teeth just like you would any other tooth. Regular brushing and flossing will help keep them healthy and strong. If you experience any pain or discomfort in your bicuspid teeth, it's important to see your dentist right away.
