  Comment I would think that
⟨ human ⟩ has part Search ⟨ teeth ⟩
quantity (P1114) ⟨  22 ⟩
would work without the need of a new property. To be more granular, I'd think of a more complex but expressive model like
⟨ human ⟩ disjoint union of (P2738) ⟨ list of values as qualifiers (Q23766486)      ⟩
list item (P11260) ⟨ young human with deciduous teeth (Q281524) ⟩
list item (P11260) ⟨ human with definitive tooth ⟩
with a metaclass to sort out human development stages :
⟨ human with definitive tooth ⟩ instance of (P31) ⟨ human development stage (tooth) ⟩
;
⟨ human with definitive tooth ⟩ instance of (P31) ⟨ human with only with deciduous teeth (Q281524) ⟩
and
⟨ human development stage (tooth) ⟩ subclass of (P279) ⟨ human development stage ⟩

Then the claim that states the number of teeth would belong to the development stage class. This allows both to model the sequence of stages later on and/or to model the gender differences (take the size : the mean woman size would belong to the "woman" class for example as the number of teeth of a young would belong to the relevant development stage).

Also, I don't like this model but I must mention it for the sake of completeness : some people created a property "number of parts of an artwork" with quantity datatype with the type of parts as a unit. This could be used here. author  TomT0m / talk page 07:28, 25 November 2016 (UTC)[reply]
Oppose I don't think that's a good way to model the data. There should be an item for the set of all teeth in the species and that set should have cardinality listed. preceding comment from ChristianKl - 12:29, November 29, 2016‎
Oppose. "Species has X number of part Y" is a very broad area, and shouldn't have a designated property for each Y. Probably better to use has part with quantity, per TomT0m. --Yair rand (talk) 05:19, 3 January 2017 (UTC)[reply]
