"You learn something new every day."

I have an operculum with my bottom left third molar. I was researching wisdom teeth because there are some root-like bumps through the gum around my upper right wisdom tooth (which is still under the gum). It’s making me worry that the roots are crawling and spreading where they shouldn’t, but maybe it’s something else completely. I don’t really know. I’ve read several web pages about wisdom teeth that are making me dread extraction. I’m almost 23 and have yet to have mine removed.

This is the very detailed information I read about wisdom teeth.
It’s not something easy for me summarize since I’m not familiar with all the dentistry jargon, so feel free to read up on it if you’re interested–or don’t, if you get easily queasy.
