i noticed these thing that have hole-like appearances on the bottom corners of my front two teeth yesterday. one is mildly sensitive, but the other is giving me no issue. i didn’t get good dental care as a child, but since I’ve been an adult I have religiously taken care of my teeth, going for regular cleanings, invested in a solid electric toothbrush, etc.

my dentist never mentioned anything and I went for a cleaning a couple months ago, I don’t drink a lot of fizzy or sugar drinks and consume a moderate amount of sugar. im going to make a dentist appointment asap, but curious if anyone can provide some insight into what’s happening?
