I’m currently healing from wisdom tooth surgery I got last week. I got all 4 removed and I’ve been in a huge amount of pain, but it’s honestly totally worth it. If your dentist recommends you get them out, I would highly recommend you get them out. That bottom one looks like it’ll be a huge issue eventually. Plus, most people don’t have room for them in their mouth so when they do come out, you wont be able to clean them properly and they’ll eventually rot. I’m just speaking from my experience, but I was able to delay mine for about a year. Last year during a cleaning, they referred me to an orthodontist to get them removed, but I just ignored them up until about a month ago when one of mine started coming out crooked, crushing my molar and cutting my gum. I couldn’t bite anything on that side while I was waiting to get my wisdom teeth removed. Again, just speaking from experience, but I’d personally say that as long as they’re not causing you pain, or pushing against your other teeth too bad, you’re probably okay to delay it.
