There are some many ways to whiten your teeth at home.

The best way is to use dental bleach, the major 2 brands are "Pola"
from http://www.polanight.co.uk ( The dentist brand) and also "Colgate
Visible white professional"

Colgate is a top brand and this NEW visble white is now available in a
super strong "Hydrogen peroxide" formula.

Colgate is a top safe and tested brand, make sure you visit
Happysmileuk.com for full details they are excellent.

Happysmileuk offer real value for money and only supply to branded
products, the same kind the dentist use but without the high price
tag.

Pola night is also a top brand used by the dentist...see

I have used Pola and the professional Colgate visible white 9% and it
was fantastic.
