I went to my dentist today because the side of my face is swollen.. He wasn't able to do an x-ray for obvious reasons but when he looked at my tooth, he said it needs to be extracted. I asked him if he was sure and he said yes. Should I take his word for it if he didn't do an x-ray? I have an appointment in two weeks and he will look at it then once the swelling goes down and we will proceed from there.
