牙位表示法是牙医学中给每颗人类牙齿编号表示的方法。常见的有：

• FDI牙位表示法，又称数字标记法，为世界通用。每颗牙用2个阿拉伯数字记录。
• 部位记录法,又称Palmer牙位表示法，用象限符号和一个阿拉伯数字记录。
• 通用记录法（Universal numbering system）：从1-32编号。

Dental professionals, in writing or speech, use several different dental notation systems for associating information with a specific tooth. The three most common systems are the ISO System, Universal Numbering System, and Palmer notation method. The ISO system is used worldwide, and the Universal is used widely in the USA. The ISO System can be easily adapted to computerized charting.
