Question: “I love to keep my teeth as white as possible. Can I keep using my teeth-whitening products while I’m pregnant?”
Answer: It’s probably safer to lay off the tooth whitening products when you’re expecting. There haven’t been any major scientific studies on the effects of using a professional or at-home tooth-whitening system (such as those that use peroxide or ultraviolet light). For now, the general agreement among dentists and physicians is that it’s better to be safe than sorry. Until more is known, pregnant women shouldn’t bleach or otherwise whiten their teeth. But don’t worry if you’ve already done some whitening; again, there are no proven risks.
