If I drink red wine, can it stain my attachments? I plan on removing my trays but don't want perms fly stained attachments.

From the beginning of my  Invisalign practice, over 14 years ago, I have always told each and everyone of my patients that there is no limitation on drinking any liquids either hot or cold. However after drinking red wine, I have always advise my patients to swish with a mouthful of water and either swallow or spit it out. This should prevent any staining of your trays

It should not stain the attachments if you do it in
moderation. It might also help to brush your teeth as soon as you can after.
