2 Days Post Invisalign:

I could see why you would find this annoying as your tongue tends to find anything unusual in your mouth. I would call your doctor and explain the situation, especially regarding the tightness with your flossing b/c this could inhibiti the trays from working properly. Friction is the biggest inhibitor of proper tooth movement!

You might have some excess bonding material between your teeth and if that is the case the Dentist will have to remove that sooner rather than later. I would recommend that you call the dentist and ask him to see you to remove that excess material so that you can floss normally and avoid any gum issues

The two purposes of Invisalign attachments are to secure the aligners and to move the teeth. There should be just enough composite used to accomplish that and no more. If you feel there was any excess left on or between your teeth, you should get in to see your doctor. Although it technically won't hurt anything, the fact that you can't floss is a problem that you need to deal with soon.

The material we use to form the invisalign attachments may be trapped between your teeth. We always try to make the attachments blend with tooth colour as much as we can, sometimes the excess material is left behind. Call your doctor and explain what happened he'll be glad to remedy the situation.

Unless there has been some kind of extremely quick space closure, causing the contacts to be tight, there is likely some resin that has been left over.

As mentioned above, the aligners may not fit properly, but more importantly, if the resin is holding the teeth together, it will prevent the teeth from moving.

It is probably a good idea to give your doctor a call and explain your issue rather than waiting until the next visit.
