So for the past couple of days, I've had one gland under my jaw which has come up swollen and painful. My lower gums on the same side are tender when I brush my teeth and one area is particularly sore as I had some food trapped down inside. It's not red though and I can't feel any lumps. I assume that this is what's causing the swollen gland. What should I do - emergency dentist or give it a bit longer? I did actually book a check up today but it's not for another month yet! It all started on Friday evening.
