It could be, but it could be the other teeth as well. The word pembe is generally used specifically for tusks (and horns).
I wrote "Teeth of an elephant" and it was marked wrong!!!! I think I am correct. Please look into this.
Maybe they want you to write 'The teeth of an elephant' or 'elephant teeth'. However, these answers are wrong because 'tooth' / 'jino' is singular and 'teeth' / 'meno' refers to the plural state.
