@tanglewooddentist: Those zingers during whitening aren't a problem. They're chemistry. Your teeth act like a sponge, holding onto whatever's stained them: coffee, wine, marinara, soda. Peroxide pulls that discoloration out, and as fluid moves through the tooth, it can tug on the nerve. Enough of a tug, and you get a quick electrical signal. That's the zing. Not everyone gets them. The ones who do, it settles down fast. It's a sign your teeth are whitening, not a sign anything's wrong.
