My pediatric detist said I was born with week teeth and that some adult teeth grew in flakey, whats it mean?

I stopped going to him when i was 18 because he couldnt do anything for me as an adult, i wound up going to see one oral surgeon to have an adult tooth pulled because it was "bad", Im now 22 and am having some trouble with my adult teeth and wisdom teeth they all tend to hurt me when i eat cold or hot foods and i somtimes think they are soft, i have a dental appointment with a new dentist and am worried he will think i have been taking poor care of my teeth when I was told my teeth were grown in in a crappy condition. Is flakey a real term, and is it possible to have all dental work done by an oral surgeon, like cavities and stuff i freak at the dentist.
