6 weeks ago I got a filling on the top left-hand side of my mouth. Since there has been a lingering pain, but about 2 weeks ago it got much worse- it is throbbing and I wake up in pain every single night. Motrin helps, but I'm taking at least 4 a day, which is hurting my stomach. Also, during the day I can often go many hours between taking it- but i can't make it through the 6 or 7 hours I have to sleep at night. I notice it gets worse in the evenings and when I'm sleeping. The tooth is sensitive, but it doesnt really hurt when I eat. It feels like it's coming from my upper gum and cheek- i also noticed ive been subconsciously biting my cheek- so am now sleeping with a night guard- which helps, but the throbbing persists. My dentist said i looked fine- filled a cavity in my wisdom tooth and said that should help- it has helped the pain shooting to my nose- but the side of my face still hurts, im waking up etc. He said to give it 3 weeks - but it is really driving me crazy to be in so much pain. I've also tried antibiotics- but it didnt help. My current routine is a mix of the Motrin- mouth guard- anbesol when im waiting for the motrin to kick in. It works fine- but I am in a lot of pain until it all works about twice a day(always in the middle of the night, sometimes at the end of the work day). I also tried prescription pain killers- but the motrin is better. Any advice? It seems unbelievable that in this day and age I should have to suffer like this for so long- I'm going back to the dentist in a few weeks- looking for insight into what may be wrong- to suggest to him - or any way to cope with the pain/ help the problem on my own. Thanks.
