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 had all my inpacked ones out last year. Tho it was a little too late and the were dead and caused the teeth they were touching to rot as well. Knew about it in my 20's but just couldn't afford the time off work (I'm in the uk so would be done under the NHS)
