Thank you for the news I have heard various people say on these forums that they no longer felt the furry feeling on their teeth after sleeping overnight or a long period of not brushing like not brushing for all day. These people were taking vitamin K2 MK four and I believe vitamins a and D. So yeah it seems like there is definitely something to keep feeling clean and smooth even without brushing. It's something in our saliva that cleans our teeth and the saliva can only be achieved if our nutritional requirements are met.
