I had to be given novacaine (or whatever it is they use) for a cleaning! The pain when the water/air hit was unbearable. No cavities, in fact, I had a lot of dental work done last year--beautiful crown & bridge work.
The denist's office who did that work was total chaos, I was in the chair once for 9 hrs, another time 7 hrs. She would start on me, then wander off to see another patient, come back, etc. It was brutal on my spine.
So, I go to a different office now. Much calmer & organized, but I never expected to be such a baby about a cleaning after all of the work I went thru (total mouth reconstruction).
I mentioned to DH that I think my pain tolerance is getting lower due to the chronic pain & he said he has noticed that. He said it's been quite gradual, but he sees it.
