Nope, not getting ready for an operation or anything like that. It just seems that my dentist has a secret deal with a dental floss manufacturer: all three fillings she's replaced so far require that I floss not daily but after every meal. The newest one is even worse and I feel like flossing after every bite I have. This leads to my gums being so irritated that at the moment I don't think I could chew anything.
I'm switching to hot chocolate!
