I haven't had major problems with my teeth whatsoever. My last visit to the dentist was so great, he rated my teeth "5-stars"...because I had no cavities whatsoever, plus I didn't need any braces. Never have and never will.
Even though back when I was in high school, I needed just one filling. That was it. Afterwards I started taking good care of my teeth that would make me go to the dentist every six months from now on. Hopefully I still keep this streak. :)
I'm the only family member that doesn't have braces. go me! :P
