Not sure what the problem is, but a couple of weeks ago i noticed that when i wake up, my lower cheek where it meets the gums
on the left side is sore
. Sometimes the top area is sore
too. I thought i was biting it in my sleep, but the area is way below where i can bite. also, my gums are a bit red and there is a white spot right where it meets the tooth. I brush, floss, and use mouth wash twice a day. There is no food stuck there.
