I use pearl drops whitening, and have for years and I find it great.

I'd say it's more our diets than lack of fluoride that rots our teeth.
I live in a town which doesn't have fluoride in the water, and so many young people have problems with their teeth... To the point that people in our town have protested that we want fluoride in the water... it would be cheaper than paying so much for people to attend the government funded dental clinic and apply for financial assistance for dentures. I grew up in Sydney, with fluoride in the water, and I have no fillings... my children are starting to have problems with their teeth, and I am so strict when it comes to their dental hygeine... the other thing I heard is that people are also drinking alot more bottled water, which doesn't have fluoride in it, which could be causing the increase in dental problems too.
