Whitening with Invisalign Tray and Attachments?

Just recently a new study came out showing the attachments do not affect the effectiveness of the bleach. However, you do say there is a cut out on your aligner that is not covering the tooth. For sure, in that case, the bleach will not reach that area. That area not covered by the try may be insignificant. Still, it is possible to bleach more later to cover that area.

You will probably find that you want to bleach more in the future anyway.

Some bleaching products have shown the ability to penetrate under Invisalign attachments and even under braces. This questions is best answered by the doctor prescribing the bleaching or the manufacture of the bleach.

Whitening while doing Invisalign, even with attachments, work fine. You your wearing trays anyway, might as well do the teeth whitening at the same time. Touch ups might be needed at the end and that's ok.

We usually recommend that whitening be
completed after treatment when the attachments are removed so that the
attachments do not interfere with the bleaching solution reaching the teeth.

In my experience, the attachments do not affect the ability of the gel to whiten at all.  Go ahead and whiten during Invisalign treatment.  You've already got the trays in all day, so use that time to get the color right while you're at it!
