I went for a cleaning a few weeks ago. They had a special air purifier by the reception desk and air purifiers in each room. They have a heavy duty plastic curtain hanging in each doorway. They have a special suction thing (in addition to the regular saliva suction thing in your mouth) in your mouth.
When I went in and had to fill out the form for Covid, they let me keep the pen because they don’t want to have it back and have to touch it. They take your temperature. So many things.
My daughter goes to the orthodontist and the child (the patient) goes in alone and the parent waits in the car, to reduce the number of people in the office.
