Will the Whitening Trays be Uncomfortable, Difficult to Sleep with or will the Whitening Gel Leak out of the Trays?

No, KöR-Seal™ whitening trays are very different. They’re comfortable; because they’re thin and form-fitting, you’ll forget they’re even in your mouth. They’re convenient; by wearing these only while you sleep, it doesn’t interfere with your busy day. Also, unlike regular whitening trays, KöR-Seal™ whitening trays seal the whitening gel inside the tray, preventing the gel from quickly leaking into your mouth.
