Hi, the ATA says the air abrasion is almost silent. I quit my regular dentist, because by luck, I read about it on this forum, and they gave the ATA link. Then I phoned around my small town here, and by some miracle, there is a dentist that has the air abrasion. when it first came out it was very expensive, so they used the cheap and noisy drill. at this point, I would rather have an extraction than drilling, so I was real lucky I had a dentist that does this in my town.
Air abrasion is perfect for a tinnitus patient, but get your teeth check very regularly and brush, because it will not work if the cavity is too big.
