Dentists recommend wearing dental braces to align the teeth in perfect condition. There could be many reasons for nonalignment of teeth; most of the factors are genetic. Very few lucky people have got a good set of aligned teeth. The degrees could vary; in some people, the misalignment might not appear very bad. Time and age also have their roles to play. Even people with a perfect set of teeth over some time tend to lose teeth and alignment as well. Hence, it`s important to take good care of teeth.
