I've been having problems with one of my teeth again in the upper left molar. I think it has a hole or cavity because it hurt when I bite and my lower left cheek is a little swollen. Beside it is my left canine tooth that was broken and still not pulled. I don't want to take antibiotics because of the side effects. I just gargle with warm water and salt at night. I am planning to go to the dentist tomorrow or the day after.
