How does the ADA number the teeth? for example, What is tooth #18, #21 etc.

ADA uses universal system of numbering the teeth. It starts from upper right posterior. For example the wisdom tooth on upper right posterior segment is tooth #1. Likewise continue counting till upper left posterior wisdom tooth (# 16). Continue counting to lower left arch till lower right arch.That means tooth # 32 is lower right wisdom tooth.#8& # 9are upper central incisors.
