Dr. Tau below gave the correct answer. There are enzymes (glutathione peroxidase) in your saliva that destroy whitening gel ON CONTACT. So it is imperative to keep saliva out of the whitening trays. The specially fabricated and precise KöR-Seal Whitening Trays, will seal the saliva out of the trays. However, when you are awake (even sitting in bed watching TV or reading a book), you salivate more and swallow more frequently and more deeply. The swallowing will actually “suck” some of the whitening gel out of the whitening trays, which causes saliva to be sucked IN to the whitening trays. However, we know that when you lay down in bed with the intention of sleeping, your salivation slows, your swallowing rate slows, and your swallowing depth slows. Then when you actually fall asleep, your salivation and swallowing almost stop. This is the reason for my instruction to wait until you are ready for SLEEP before putting in your KöR-Seal Whitening Trays, and why you should not sit in bed watching TV. Hope that helps.

What you describe as Deep Bleaching most certainly is not Deep Bleaching. Not even close. Many dentists, and in fact some whitening product companies around the world claim “Deep Bleaching”. I’ve even seen a few that use my name with their advertising. These are fakes. There is only one genuine Deep Bleaching, and that is KöR Whitening. KöR Whitening can be done as “Deep Bleaching”, which is at-home whitening using a VERY specific whitening gel formula in VERY specifically designed whitening trays called “KöR-Seal Trays”, followed by an in-office whitening. Or KöR may be done with ONLY at-home whitening, and it is quite effective, although it cannot be called “Deep Bleaching”. You may want to check the KoRwhitening.com website to see if your dentist is using genuine KöR Whitening protocol and products or not. Dr. Rod Kurthy
