It is a hard plastic type deal that is. all enclosed together over 3 teeth. and very hard to come off I chip it off tiny pieces with a toothpick. it's very weird it's not film a film is on my eyes. let me know if you find a way to enclose pics. I also have three teeth that have been broken in half and the three that are enclosed I kept very white. how weird. I have hyatidid cysts and pelodera strongloid. Lots of pics in images.
