OOh my favourite topic. According to my dentist my teeth are the whitest natural teeth can be, woop!
2 good tips
1. Whitening kits- buy for about ?15 - 20 from Superdrug THEN go and have a sunbed with one in, it accelerates the whitening and about 2 gos will give you a great smile. Leave them in slightly longer than it says on the packet.
2. Don't give up coffee or wine, sip them through a straw. Yes it makes you look like a twat, but the pigment won't make any contact with your front teeth. Score!
Will post more tips as I remember them. But the kit from Super drug is brilliant, has a mouth tray, whitener, and accelerator and lasts ages.
