Dentists tooth numbering varies between 2 alternates schemes in UK & USA, & 1 other in Germany etc, (& 3 more variants in USA armed forces !)

Relevant to eg

Foreigners/ Travelers: People who have teeth fixed by dentists in different countries etc using different numbering, & want to understand from old bills, which tooth was fixed when, how often, eg to decide if now time for a crown, (also thus useful for self, dentist in the other country &/or health insurers).
Tooth Removal Candidates: Someone who has an extraction pending. a referal from a dentist to a dental surgeon, wiki notes how sometimes then, a second numbering system is added, to reduce chance of wrong tooth removal under narcosis. Having learnt that, I'd want any referal paperwork for extraction to additionaly specify tooth in a 2nd system too.
Identity Theft: ... eg "distinguishing features" section in passport etc, if one has had a brace, & lost teeth from that or other causes, one could list numbers (in both systems), to make ID theft harder for criminals who steal ID docs. A UK pasport & dental work done in Germany involve 2 different numbering systems.

There is another American scheme, Letters & Numbers (also used additional as a check against false extraction instructions from dentists to dental surgeons; (wikipedia.org example in English lists German 24, (rather than American 12) for UL4 ! Why ? Do Germans use Palmer too ? ).
