Is there such a thing as a cheap but effective

Teeth whitener???

Arm and hammer toothpaste does a cracking job. If you drink coffee like me, when you rinse after brushing it's all beige... Eeew... I really did notice a difference.

Yes, I second Arm and Hammer! I use the enamel care one with liquid calcium in it, it's really good!

Does it taste a bit weird?

Nope, just normal mintyness! The texture is slightly different to regular toothpaste THOUGH, it's slightly runnier and has a very very slight grainy feel IYSWIM.

Use a piece of cotton wool and pearl drops tooth paste and literally polish your teeth to remove stains.

I think the Arm & Hammer ones have an almost 'salty' taste at times, and the grainy feeling is yuk.

They work well but I can't stand the taste so I use the Beverly Hills Enamel Whitening and think its great. You can leave it on for 1 minute before brushing for extra whitening.

I don't know why I capitalised the 'though', must be past my bed time...
