May 12th

I'm a little concerned because the left side of my mouth is very tender and sensitive. That's the side where I had my root canal done, and it was all right up until today, but now my upper teeth are having bad sensitivity to cold for some reason. Even drinking water is painful, and one or two teeth on the bottom are sensitive too. I don't know if this is normal, but if it's still going on throughout the weekend then I'll have to give my dentist a call. Because I totally want to go back to the dentist again so soon!
