I've had my teeth professionally bleached by the dentist (£300 for top £300 for bottom) and it lasted about 2yrs. Since then I've use Crest Whitening Strips which I buy everytime I go to the US but now since my best friend is dating a US serviceman he can pick them up from the base for me. $20 for a 7 or 14 day kit (I'm drunk I can't remember, lol) and results last for about a year and lighten your teeth by about 5 shades. Never tried over the counter stuff but these strips are the f'ing business. Look on Ebay for them.

Has anyone here ever used any over the counter teeth whitening kits to whiten their teeth? Did they work?
