Martha Saucedo, a licensed dental assistant, works with a patient Wednesday, May 13, 2020, at Calcagno Cosmetic and Family Dentistry in Rochester. On top of the personal protective equipment normally worn, Saucedo wears an N95 mask under a level three mask, disposable gown, a face shield and a head cover. Dental clinics were allowed to open this week along with other medical and veterinary clinics as part of an executive order from Gov. Tim Walz. Clinics had been closed as part of a previous executive order to help curb the spread of the coronavirus. (Joe Ahlquist / [email protected])
