YANBU.
I work fulltime, and I can just about afford to go to the dentist, and every time I go, I hope and pray there's nothing important to be done.
I seem to have really very bad teeth, despite taking care of them quite well (I have dietry needs which mean I have no choice but to treat my teeth well as a sort of good sife effect!).
I have discoloured teeth, a couple of fillings (silver), and very crooked teeth. I have NEVER missed a 6 month checkup, and have always go ahead with treatment if medically neccesary. I also have a bit of an overbite, apparently.
But my teeth is actually one of the things I genuinely wish I could fix - I'm not vain, I wouldn't consider plastic surgery, I just wish, for example, that I could eat an apple without spending 40 minutes trying to pick the pieces out of the two worst areas of my mouth - chronic overcrowding on the lower right, and on the top right side.
I also know that the crooked edge of my teeth makes them look quite bad (small chips, basically).
I do notice when I meet people for the first time that they "register" my bad teeth, and yes I have cried about it in the past.
I'm actually saving up to do something about them long term, I opened a saving account last month for this purpose. Not to make them white and perfect, but just to make them less hideous (and get rid of the worst of the crooked issue which makes eating a problem).
