I have to ask for manual cleaning. In a past life it would have been very difficult to endure, nowadays it's child's play compare with what we must endure. This condition, whilst harrowing, also makes you strong. Stronger than you know.
I cancelled my normal cleaning in July, a month after onset and never rescheduled it. I dont even use my electric toothbrush anymore. I could endure it, but I rather not.
It wasn't the cleaning that was an issue for me. It was the loud high pitched squealing of the drilling for dental work. And that was even before my hyperacusis set in. It did make a tone flare up for a few days.
