“Dental Appliances: Problems with Acrylic”
I once saw three students who were patients of three different dentists, all highly skilled. These students each had a different type of acrylic appliance. They had been checked by their respective dentists, and all the appliances had been found to be of great benefit. In each case, however, we discovered that the student was allergic to the acrylic and thus was being harmed at the same time as he was being helped.
