Crest has a site called dentalcare.com and Colgate also has one but I can’t remember the websites name.
Colgate oral health network. You sign up and have free access to tons of seminars/webinars. They notify by email when new ones are happening. They have great, relevant topics…I love it!
gsc study courses are what I use for continuing Ed. They have on line classes and or classes mailed to your home.
