I've just finished orthodontic treatment so thought I'd treat myself and get my teeth whitened. It cost me £140-the orthodontist made the little plastic teeth moulds and then gave me the peroxide gel syringes to use daily at home. I've just finished 10 days and my teeth are really lovely and white. I'd definitely recommend it. It's called polar night,I've just been on their website and you can buy directly from them for a fraction of what I paid so I feel like I've been ripped off by my orthodontist but I'm so pleased with the result and I don't think I would have had the confidence to do it without his recommendation so I'm not too pissed off about it.
Just thought id suggest it in case anyone here wants to whiten their teeth but cant afford dentist prices.
