Ugh, I can relate. After a root canal, I went to the dental / oral hygienist for a cleaning (as recommended by my sweet dentist). It was an awful experience. She was mean, rude and judgmental from the start. When she was cleaning, she was applying brute force and was hacking away at my very sensitive receding gums. Hubby was with me, keeping me calm throughout the dentist appointments but we didn't think he need be there for the cleaning. We were wrong. I raised my hands several times for her to stop and give me a break but she just carried on hacking. I was distraught! I don't care if my teeth fall out, I'll never go back!
