Dental Refinery:

Core Scientific helps educate dentists on how to maximize their returns on extracted crowns. Many dental offices still throw their extractions away or sell them to unscrupulous people that pay cash on the spot. When you send your crowns to Core Scientific, we do a full analysis on the material refined. What does this mean to you? Hundreds or in some cases thousands more!
