For my past few cleanings, they also used an ultrasonic scaler. Two of my upper porcelain veneers fractured within days of my appointment. Could the scaler have done this? Are there different types of scalers? Is one more likely to damage porcelain veneers than the other? I think my dentist told me that they use a magnetostrictive scaler, which they said is the most gentle.

Dear Laura,
There are two types of ultrasonic scalers – piezoelectric and magnetostrictive. Cavitron by Dentsply is one of the more popular versions of the magnetostrictive scalers. While it is true that this type of scaler is more gentle than the piezoelectric ones, they are more dependent on the technique of the person using it. When used correctly, it is perfectly safe for both teeth and dental work, including porcelain veneers. However, if the hygienist’s technique is off, it has greater potential to do damage.
It’s possible for the veneers to be chipped, but you said your porcelain veneer fractured. The only way I can think of to crack a veneer with a Cavitron would be for your hygienist would have had to use the scaler’s tip directly on the porcelain veneers. This is not something that any hygienist with a clue of what he or she was doing would allow to happen. If your hygienist did that, I would switch practices right away, as well as having them pay for the replacement veneers.
You also would not want one who causes nicks on your teeth or veneers or even creating a roughened area. They should place a high priority on protecting both your teeth structure as well as any cosmetic work.
If a dental office does cosmetic dentistry, they should also be training their staff on how to clean them. For example, they should never use either acidulated fluoride or a power prophy jet on your cosmetic work either.
