Being fair to Aristotle, it may be the case that empirically, in Ancient Greece, or in whatever sample he used to check his claim, the women did actually have fewer teeth on average. Worse nutrition, more stress on the body due to pregnancy, whatever. If you check ten women and ten men in a non-modern community you might easily get such a result by sheer chance.
Since a large part of what he did was checking empirically, I don’t think your opinion is justified. Really, the most likely explanation is that he checked empirically—the same way he observed that the kidneys filter urine, that some sharks give birth to live young, and numerous other biological discoveries that were obtained in part through first-hand vivisection.

I don’t think that Aristotle did check empirically, though.
