I know someone who is a dentist (endodontist, all he does is root canals) and he says there is some risk that whitening will damage the teeth internally, eventually causing toothaches (maybe when you're 40+), and they will need to be fixed by root canal. But he says it is not known for sure because whitening is a new thing.
If you need a root canal, it's expensive, painful, and kills the tooth (it will never be the same again).
