How many baby teeth are there, and how are they labeled?

There are a total of 20 baby teeth, commonly referred to as primary or deciduous teeth. These teeth are labeled with uppercase letters ranging from A to T. This labeling system helps to differentiate them from permanent teeth, which are numbered or labeled differently in dental practice.

In the primary dentition, the 20 teeth consist of 10 in the upper arch and 10 in the lower arch, including incisors, canines, and molars. Understanding this labeling and the number of teeth is crucial for dental professionals as it aids in communication and record-keeping when dealing with pediatric dental patients. The other options present incorrect counts or labeling schemes that do not accurately represent the characteristics of primary teeth.
