In case where you have a wisdom tooth in place that sometimes feels like it may have to be removed, sooner or later, then go get it removed. The sooner the better. If for the most of time the tooth doesn't bother you or hurt, it's easy to keep procrastinating and postponing the operation for years or even decades.
Trust me, the healing process is a wholly different beast when you're in your 50's compared to if you were in your 20's or 30's.
I was getting infections from the way my wisdom teeth came in, so had to have them removed. One of them the doctor said he had to split and take out in pieces because he couldn't get it out otherwise. It bled for about 2 days, I was swallowing so much blood I was vomiting, worried about the stiches in my mouth.
