Obviously   Juris prudence  teaching  and  exam needs  to be  done  at  the beginning of  Dental Licensure, but  a  schedule of  a 3 year re-exam is too frequent.  When  dentist go  from  being  an employee, to opening  their own practice or  being  a "manager" of other  dentist  they should probably have  a retraining  and  re-exam.  Also  someone  coming out  of  the military,  civil service or public health job  should  have  re- training and re-exam, before going into private practice.  New rules/regulations could  be sent  to  dentist  and have  a short  written  test or  short  on line test  associated  with  these new changes  to make  sure  dentist have  really  read  all the changes and have an understatnding of  those  new changes.  Maybe  an additional  full test  at every  10 years.
