The assistant that worked with my dentist did not know how to operate the suction device. After many notifications that she was sucking the dry part of my cheek and not attending the area that was most in need of attention she continue to suck the area that did not need suction. My dentist had to give me 4 anesthetic shots for my upper cavity after I repeatedly told him that it hurt as he drilled. It has been close to 3 weeks and my upper jaw is still sore.
