I don't know if it is appropriate or not..... I saved my baby's teeth.
I was able to 'catch' Kimchee's 4 baby teeth; he was playing with them after falling off. The vet also saved all 9 teeth that he extracted from him for me.
Unfortunately, I was not able to 'catch' any from Mochi, I believe she ate all of them.
The vet also did not save the 10 teeth that he extracted from her.
