Many adults sit in the dental chair and say some version of the same thing: "My teeth used to be straighter. I haven't done anything differently, so why do I have crooked teeth now?" Anecdotally, at our clinic, Wigmore Smiles & Aesthetics in Luton, it is one of the questions we hear most often, and the honest answer is that crooked teeth rarely have a single cause. There is almost always a combination of things going on, some of which started before you were even born.
