if you look on the Q Clinic (Harley Street) website you'll find that their own monthly offer comes in cheaper than that.
As someone says further up, you'll need to also factor costs for retainers after you complete your trays, and their is a risk that they may need to shave small amounts away from some teeth to create the space to move your teeth. The amount shaved is less than a milimetre, causes no structural damage to the tooth, and all gaps are closed by the end of treatment.
In answer to the question higher up about children having this fitted, I don't know, I guess that is one for a qualified professional. I would say that general train track type braces are much more precise now than they were when I was growing up and so are probably a better bet.
Another thing to consider is you will need to wear your trays for at least 22 hours a day, if you don't take care of them they becoime visible. So you need to be sure that you'll be disciplined. My dentist says that the main reason for failure is that people don't wear them enough.
Re retainers, the answer is it depends on your bite shape, what type of retainer you go for and whether there are any other issues like say grinding your teeth at night.
The retainers recommended for me are a combination of trays and fixed wire behind my teeth. Obviously the fixed is fixed and you would hope it stays there long term. Re trays, I guess the answer is the longer you wear them (at night only) the longer your teeth have to settle and stop moving. Depending on your bite this may be a year, or if you have teeth like mine that like to move, I guess that I'll be wearing them for at least a couple of years, decreasing the frequency as I go.
I hope that answers the questions directed at me, feel free to PM if there's anything I've missed. Apologies for any nonsensical bits.
