Well, yes it is a good oxident so depending on the concentration and, it
can damage your gums, however if used correctly you shouldn't have too much issue in my awareness. 6-10% w/w is the usual for brushing teeth from what I recall, and is thought to be safe for regular use i.e once or twice a week from my understanding. Also note that damage can occur from gum disease, overly traumatic brushing and the use of mild abrasives such as bicarbonate soda which is often touted as part of a home whitening remedy in which H2O2 has also been popularised.

this is a solid place to start, and if you are familiar with effectively reading clinical or peer reviewed reports and aren't worried at stumbling through any jargon,
Google scholar is a good resource for further enquiry.
