Last week, I got fillings in both sides of my mouth. For the first few days, I felt fine, but since Sunday, I've been experiencing a lot of pain in the jaw area and in the teeth themselves, somewhat. The pain comes and goes every few hours rather than being an all-day thing. It seems to come every evening sometime before I go to bed. Then when I lie down, the pain gets much worse. I've read that this is because the blood pressure in the head goes up when one lies down. The pain while lying down is too much for me to fall asleep with, so I've been taking Tylenol every night. I'm a bit worried about the effects of daily Tylenol consumption on my liver. Also, I'm quite concerned about this pain coming back multiple times every day.
