I had a small crack in a molar that was more of an annoyance than painful. The dentist said the tooth looked fine on the x-ray and all it needed was a crown. Easy peasy he said. So, they did their thing and put a temporary crown on. It's been 7 days and it's been hurting ever since, much worse than the cracked tooth did. It has lessened somewhat, but eating on that side is impossible. It hurts my gums to floss around it, but brushing is OK. I don't feel any "zings", it's just an ache whenever I bite down on anything. It hurts the most when I wake up, I'm assuming from clenching my teeth while I sleep. I've been taking motrin/tylenol around the clock and the pain does subside as long as I don't chew on that side. I know they did a lot of prep work on the tooth, but is it supposed to hurt off and on like this?? I wasn't given any instructions.... I have another 2 weeks until the permanent should be in.
