I know for a fact, I have all four of mine in my jaw, however, I have one on the bottom left that has been coming in for around two years now, and on that same side I have the one at the top trying to come in. On the right side, I thought the bottom one was trying to come in, but I have seen absolutely no progress with it and the top one also has not cut through. I was told by two dentists that I have enough room for my wisdom teeth to come in and then my dentist office was bought out by a new person and she keeps telling me I need to go get them removed, but I’m not going to do that since they’re not causing me issues.
Back in the 1990s everyone was pretty much told to get those things removed because there is no room for them. I only had 3...don't know where number 4 is growing haha. My husband and I had them removed at the exact same time and he developed dry socket because he didn't follow directions. I had no issues at all.
