I take extremely good care of my teeth so I was surprised when I discovered that the top right side of my gums
and my bottom right side of my gums
(exact spot), appear to be irritated and sore. I went to bed knowing that the bottom was irritated, but I thought it might just be a canker sore, and when I woke up, the top was irritated too. Any ideas of why this happened or what it could be a sign of?
Thank you in advance!
