We have three kids so I found this very interesting.. A new study by Germany’s Heidelberg University finds that mothers with three kids have an average of four fewer teeth than moms with just two children. Researchers also found that moms who had a third child after having two of the same gender had far more missing teeth than mothers of three whose first two children were of different genders. The same dental effects weren’t observed in men. Our first two were girls so I guess I better get my wife into the dentist quick LOL Is this true? Tell me what you know!
