how much does teeth whitening cost?

im in the UK
--------------------
There are few ways of teeth whitening - In-home; Office, Whitening strips. Since you had braces, I guess strips won't work for you. Office whitening is the most expensive. It goes 6-10 shades immediately and costs $400-$800 here in States - depends on the method, your doc, etc...It's done by putting the bleach on your teeth and using the light to work on it... In-home kits are in my opinion less invasive, less painful and more suitable for your age, if you really need a whitening. The doc will take a print of your teeth, will make a form and you will just put a whitening agent inside and stuck it on your teeth for some amount of time. It takes few days, but the results are same or very close to the office method. I had an office method done last year before getting a crown for my implant. For me it was horrible experience. I have a sensitive teeth and 2 hours after the procedure I was in excrutiating pain. It lasted for few hours and was gone, but I would never do it again. If I ever needed to whiten my teeth, I would opt for an In-home kit. Since you are 13, the whitening is not very good for you, but after the braces removal your teeth may be stained. Your dentist is a specialist and he will determine the best way for you considering your age, your teeth sensitivity, etc. Good luck! :)
