Can I use teeth whitening strips if I am pregnant?

Using teeth whitening strips is not recommended if you're pregnant. Teeth whitening strips are dental products that contain a mild concentration of peroxide, which bleaches teeth. Teeth whitening strips are generally safe to use. However, scientists are not sure whether the chemicals used in teeth whitening strips and similar products pose any danger to an unborn baby. Because of this uncertainty, it makes sense to wait until after your pregnancy to have your teeth whitened.
