i had a tooth in the top back of my mouth pulled last thursday and i'm having problems with my gums around that area. about 3-4 days ago i started to have a raw swollen spot on my gums and it hurts when food, liquids, or my tounge touches that spot. not sure what to do about it. do you think its an infection and maybe need an antibiotic or just gargle with salt water to make it go away. i do have a doctors appointment this week. pls help. thanks!
