Dear Abby,

I must respond to “Always His Mom” (Sept. 26), who asked what to do with her grown son’s baby teeth. She can contact the college of dentistry close to her and ask if the school would like to have the baby teeth the Tooth Fairy collected.

When I was in dental school, we used deciduous teeth (baby teeth) to study the dental anatomy of children. It’s rare to have a complete set from one person, which would make these a good learning aid for students. When I was in school, the deciduous teeth were nearly smooth because of the number of students who had handled them, making them very difficult to identify.
