I have used janina whitening in the past it was good product gave me 2 shade whiter tooth in 2 weeks but it was expensive and small container ( 50mg).

does anyone know of a better and cheaper product? is BlanX any better?
also seen the brilliant whitening in tesco and boots.

is home kit better than toothpaste? which one is best ?

I have done laser whitening paid 250pound but wouldnt recomend it at all. my teeth are around shade 6 ( i guess) and the laser whitening only made it 1 shade whiter and defo not worth it ...
