Yes, they are noisy.  It can also be painful in the beginning.  Just use
less pressure when you first start out.  Your gums have to get used to it.
After a week slowly increase the pressure.  I had a few painful spots in the
beginning that I would avoid for a few days and then they were fine.

I have never heard that a WaterPik would loosen your teeth.  We chew and
bite into food all day, if that does not loosen them I don't think pulsing
water would.  I have read somewhere though that if you have a lot of amalgam
fillings you would  be better off using a WaterPik than brushing.
Supposedly the brushing releases the mercury in the fillings.
