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.
Yeah there was a big trend in the 20th century to systematically remove wisdom teeth, tonsils and the like. But it turns out most of the time it's not medically necessary, and some research suggests it can be detrimental.
