ZBrush morph does not affect teeth

Hello!
I have created a face morph in ZBrush, and I have applied it to my model in DAZ.
It works great, but once I opened its mouth with a smile morph, I could see that the teeth are not affected by the morph:
Then I compared it with a professional authored face morph like Tauranette. It turned out this Tauranette face morph affects the teeth as well.
How could I make it so that my ZBrush affects the teeth, too?
Thank you!

Did you sculpt the teeth in ZBrush? It won't automatically move them to match the changes in the outer surface.
No, I did not. Thank you!
