My son went to the dentist last week and came home complaining about his jaw hurting very badly. He had gotten a filling, but the way his mouth, jaw and even his lips were puffed up, didn’t make sense that getting a filling would cause that reaction. All of a sudden it stopped hurting. Come to find out, it is his wisdom tooth in the back left coming in. The dentist neglected to tell my son or husband who had taken him in, about the wisdom tooth, though the gum was obviously red and swollen. The poor kid is going to have to have them removed. I feel so badly for him. At least for now it’s not hurting him like it was.
