I haven't been to the dentist in years and need to go. I don't think I have any cavities just lots and lots of plauqe to scrap off. However I know the ultrasonic scaler is loud and high pitched so if I ask would a dentist just do manual slower scraping instead? I tried picking some off with my finger nail and it's on there hard. Or is it gonna be something when where I get there they say nah I tried but it's too hard to scrape off I need to use the ultrasonic?
They should be able to give you earplugs or you could get noise-cancelling headphones. It's just one of those adult things we all have to do. Don't over think it, let the dentist do their job and focus on being a good patient.
