The discussion of the safety of tooth whiteners with peroxide has focused on the harmful effects of the free radicals generated in the whitening gels, specifically, the theory is that when hydrogen peroxide leaks from trays containing the whitening gel onto surrounding areas inside the mouth, it triggers the release of cancer-causing “free radical” cells.
So how to prevent this is by either doing in-office teeth whitening which all your gums and surrounding tissues of the mouth is isolated which prevents this leakage or use home teeth whitening which you can get from your dentist which utilizes a custom tray fitted to your mouth which will minimize the leakage tremendously.
Over-the-counter products do not use custom trays, even the ones you heat up and bite into is not considered a custom tray, hence leakage is not avoidable.
So to answer your question: Can teeth whitening cause cancer? The short answer is yes, but not confirmed, as well as if yes, the chances are very low depending on which products you use.
