My wisdom teeth started to come through when I was in my teens. The bottom ones never did come all the way through--the front halves of the teeth were showing, but the back halves were covered by gum. My dentist nagged & nagged & nagged at me to have them out, but I was a chicken & kept refusing. Those teeth bothered me off & on for years--they'd have spells where they'd itch & HURT, then they'd be no problem for awhile & then they'd start in again.
I finally gave in when I was in my late 20s & had them pulled--lucky I chose the right one to start with, as it just popped right out, no problem at all. When I went back to have the left one pulled a few weeks later, it put up more of a fight--it broke in half & the dentist had to dig around a little bit to get the last part out, but even so it wasn't too bad. I didn't have any wisdom tooth at all on the top right, and just a spike on the top left. After the bottom ones were gone that spike started to work out & was digging into the bottom gum so I had to go have it out too--it came out real easy. I sure am glad to have those gone, & I admit that after I had the first one pulled I did wonder why on earth I had put up with the discomfort from those teeth for so many years!!
