What does tooth #4 identify?
Tooth #4 identifies the upper right second premolar in the Universal numbering system used in the United States. It is a back tooth. Its matching FDI designation is 15.
A treatment plan or benefit statement may use the number alone. Confirm the number with the dental office if the document is unclear; a tooth number identifies location and does not explain a diagnosis or treatment by itself.
