It is hard to ever imagine that any of us in west London would ever see the say when the art of teeth straightening would ever be called pleasurable: the idea of braces conjures up images of long and ugly-looking treatments. But that is no longer the case anymore as Invisalign has come along put paid to these problems. It is a fairly quick treatment, lasting about 9-18 months, depending on how bad your teeth are, but as the treatment progresses, you will change your aligner quite a few times to ensure that you keep your teeth on the go all the time. Invisalign is removable, so as long as you wear it at least 22 hours a day, you can take it out to clean and to clean your teeth as well. But the most amazing quality that Invisalign has is that all of the aligners you will wear are made from a clear, transparent plastic, which means that when it is fitted into position, it is barely visible to anyone else. It is this set of qualities that set it apart from other devices on the market; but it does come at a price; it is one of the dearest treatments about, but the price is irrelevant considering what this aligner does and how it does it.
