DES MOINES, Iowa (KCRG) – Governor Kim Reynolds has signed a bill allowing dental assistants to work without state registration. The bill is meant to address the dental assistant shortage in Iowa. Dental assistants perform many jobs, including giving the dentist the correct tools, taking x-rays of patients’ mouths, and sanitizing. The bill, HF 805, creates a separate tier of dental assistants. Some dentists have expressed concerns over the bill, claiming it may mean less accountability for those doing the work. The bill was signed into law Thursday.
