The History of Dental Hygiene………

This week I have to give credit to


What an amazing time line to read…

 In the early 20th century, a few progressive dentists promoted the idea of preventive care and transformed the health of the nation over the next 100 years. First implemented in public schools, regular oral hygiene and patient education significantly reduced tooth decay and mouth disease. Who performed the work? Dental hygienists—a profession launched in 1913 that numbers more than 181,000 practitioners in 2012
