Tooth numbering systems
What are all the different tooth numbering system? Practicing in San Francisco, we get patients that get referred to us from all across the world for their oral surgical needs. When we ask for their charts however, on most occasions the teeth numbers do not match up with our numbering system in the US: The “Universal” system.
The diagram below is a great cross reference for the three most commonly using numbering systems. The “Palmer” system is mostly used by the orthodontic community and the “FDI” system is used by the Europeans and has been adopted by the World Health Organization (WHO). In any case this is a great reference for any of us that is trying to figure out, what is tooth #47?
