I don't know anything about Mexico, but I would encourage you to get your teeth straightend anyway you can. I was in braces from the time I was 39 to 43. I was told that my teeth were so crooked that I would lose them by the time I was 50. I was eating my own teeth. Im now 66 have a perfect bite and nice straight teeth. It is one of the best things I have done for my self. Oil pulling has made them better then ever. I know lots of people my age that have lost there teeth, and they are miserable.
