Can I use whitening mouthwash if I have bonded retainers?

yes, you can use any type of mouthwash with bonded retainers. but for best results , i prefer office whitening.

You can use a whitening mouthwash even with a bonded retainer. Don't expect much change in the color of your teeth. Mouthwash isn't in contact with your tooth structure for very long. Better results would come from using a tray whitening system provided by your dentist.
