Teeth Crowded in Seniors, as Jaws Shrink

The size of our jaws decreases with age. This is shown in a unique study from the Faculty of Dentistry at Malmö University that followed a cohort of dentists throughout their adult lives.

The unique study started in 1949. Plaster molds were made of the jaws of dental students, who were then in their twenties. Ten years later the procedure was repeated, and in 1989, forty years after the first molds, a final round was performed. On that occasion the researchers were in touch with 18 of the original 30 participants.
