(Concern) I am worried about teeth whitening.

Hello. I want to whiten my teeth.

Are you considering teeth whitening?

I'm currently undergoing orthodontic correction, and I'm curious if anyone has tried whitening treatments and how they felt about it!!

I'm wondering if it's okay to do during orthodontic treatment and what the effects are. Does it need to be done periodically? Are there any side effects? I have been smoking for a long time, quit recently, and now I want to live a clean life from now on.
