Hi, I'm new here and i need some advice. My tooth had an infection , my dentist opened it up to drain it but couldn't. So i was put on penicillin and i just finished it. After he opened it i waited a week to bite on it. when i did it hurt like hell. Then the pain went away. Now it's back with a vengeance. Sometimes it's ok like right now since i decided not to bite on it. I already had a root canal , i'm just wondering should i just take some painkillers and wait or does it need to be removed ?
