2 days ago I felt so tired one day, I could not even move, and it was a 24 viral thing I'm guessing... I feel fine now, but yesterday I really brushed my teeth thoroughly, I flossed like 2 times, brushed acouple of times, and used Listerine 2 times in the morning. Then I noticed later my mouth was irritated and very dry. The skin is peeling off, and I don't have alot of saliva. I also have about 3 canker sores, which I get canker sores alot. I dont know if this is just a viral thing, or I irritated my mouth... The toothpaste I started using that day was Colgate-tarter protection- i dont know if this is irritating it or what... I dont know if I should contact a dentist or wait...
