I had a dream that my molars were overly large to the point where I couldn't even close my mouth properly. They were causing me severe pain and headaches. It almost felt like my jaw was going to break with how large they were, and how overcrowded my mouth was.
I went to a dentist but he didn't have any appointments for me, even though I was clearly an emergency case. In the end, the molars started to break and crumble. I could clearly hear the splintering noise, like when you break ice cubes in your mouth.
When I woke up, I felt my teeth and I was relieved that they were normal.
