The Decline of my Teenage Teeth

I was poking around out in the garage a couple of days ago, looking for something.  I didn't find it, but I did come across an envelope which contained dental X-rays of my teeth from back in the 1970s!  There were X-rays taken from 1971,1973,and 1974, when I would have been 16,18, and 19.  I was surprised to see how many fillings I already had, at that young age, and how rapidly more were being put in over those few years.  I have no memory of all that dental work, or who the dentist was.  I do see that the name shows 'Julie Aaron'.  My first name back then was Julia, and for a period of time I was called 'Julie', which I never liked.  I can also see my sideways sitting wisdom teeth still in place in these X-rays.  If memory serves, I had all four of those extracted in one session when I was 21.   What about you- have you had your wisdom teeth extracted, and if so, at what age?
