and yes i have asked that, does any whitening strips or anything break down the cement
I had a permanent retainer for almost ten years. The retainer itself had come out and all that I had left was the cement. I went to my dentist and within five minutes it was gone. Very simple. But nothing else works. Sorry, but go see your dentist.
The cement is extremely durable and therefore the white strips cannot harm it. You can use them and not worry. Usually the retainer must be removed by force or the cement breaks when eating something extremely hard. JAMRDH - a dental hygienist
