I recently dealt with this after a long layoff. This was my experience:
- I bought my own ultrasonic cleaner on Amazon and got caught up on the worst teeth using short sessions at home with earplugs and phones.
- I asked the hygienist to only use manual tools and I held the suction tool away from my mouth myself and only used it a couple of times.
- For my fillings he used the laser, aluminum oxide abrasion and the low speed drill for everything except the final shaping at the very end.
- I wore foam earplugs and large ear defenders.
- No permanent increase in tinnitus or pain hyperacusis, just a spike for day or so.
- All in all, it went OK so I went back for the second round of two more cavities and will handle the remaining two exposed roots next month.
