I know for years the dentist would show me the X-ray of my impacted wisdom tooth the lower one and recommended to have this extracted. At the time it wasn't bothering me but it was hard to get back there to clean and it not being all the way in or out I had to make sure to floss so food didn't get caught.
Long story short 10 years later I wake up with a annoying tooth ache and it was the impacted one giving me the headache so having the lower left side extracted the dentist just took the upper on that side out. I still have my other two which are completely in.
Personally, I don't believe there is a law that says you must have your wisdoms taken out that is if they are all the way in. I would leave them and not worry about it which that was my plan except the one impacted one started hurting and that screwed that plan up
but all is good now.
Not sure if anyone else here has this but I still have a baby tooth.
