I just had two BIG fillings filled today, one of them being on my top right molar that may need a root canal per the dentist. He only filled it, hoping that it won't have to go that far. We discovered that I need A LOT of novicane to numb me. I had my fillings at 11:00, and started having pain about 1, so I took some ibuprofen, around 8:00 before bed, I hurt more than earlier and took some more ibuprofen. It's looking like every 6-8 hours I'll be popping ibuprofen, I'm assuming its from all the novicane they had to use an the tooth being messed with. I figured I'd call the dentist tomorrow afternoon if it doesn't settle down.
