Did you know your Invisalign trays can double as custom whitening trays? In this video, Dr. Mac explains how patients can safely use whitening gel inside their Invisalign aligners to brighten their smile. Since Invisalign trays are already custom fit to your teeth, they can work very similarly to professional whitening trays provided by your dentist. This simple technique can help patients whiten their teeth while they are already undergoing Invisalign treatment, making it a convenient way to improve both alignment and color at the same time. If you are considering teeth whitening or Invisalign treatment, it is always best to consult with your dentist to determine the safest and most effective whitening options for your smile.
