Toothache

My teeth and gums on the right side of my mouth have been aching for the past week. It is getting better though. I think my wisdom tooth is growing. Does anyone know how many wisdom tooth we will have? I thought mine grew last year, just not as painful as this one. I have not been able to chew my food thoroughly and just force myself to swallow the entire chunk. It's driving me up the wall! Arrghhh... Anyone with some good advice regarding toothache?
