I do not have any wisdom teeth; they are just plain not there (according to xrays); so I never had to go through the whole wisdom teeth removal.
In addition, I never had to have braces either.
Nor have I ever had a cavity, b/c, according to my dentist(s) (multiple dentists thru-out my life): "my saliva must be good" and must sort of fight the cavities. (summarizing according to my best understanding of the topic)
So, this, combined with all of the other posters, just goes to show everybody's teeth really are different; you just never know!
PS Don't be jealous: I have lots of other physical and mental and emotional problems. They just do not happen to involve my teeth!
