And question number five, is teeth whitening really bad for your teeth? Listen, everything in moderation, guys. If you’re getting a little obsessive with the teeth whitening, it can weaken and damage the tooth structure, but if you bleach your teeth once a year for example, you’ll have nothing to worry about.
But before you decide to whiten your teeth, make sure you consult with your dentist because not all stains can be lightened and you may have crowns or bondings that won’t lighten with the teeth that you want to whiten, so you’ll end up with multiple colored teeth.
