What toothpaste do you believe makes your teeth the whitest/brightest. I currently use Colgate but I am not sure if I should change to a different brand.

I presently and have mostly used Colgate and think that it is the best.

Naturally speaking baking soda. Whitens and cleans well.

Crest makes a toothpaste called Vivid White. It not only has stain removers but also stain inhibitors(stains won't stick to your teeth as easily). It comes in a Night version as well that is supposed to help brighten teeth as you sleep.

Crest Pro health is what I use and it works good on keeping my teeth whiter

Along with your brushing. Try to avoid coffee tea and sodas. They stain your teeth pretty bad

Smoking, red wine and dark soft drinks are great stainers too!

I use a mechanical toothbrush, so I think that helps too.
And about the smoking and wine staining my teeth, my parents would definently kill me if I was to drink or smoke... lol

Fluorodine Oxygen white is the best toothpaste for removing stains and Whitening your teeth.
As I’m addicted to coffee, I got yellow stains on my teeth. Then I started using Fluorodine Oxygen white toothpaste, within few days yellow stains disappeared. Thanks to Multibrands and Fluorodine toothpaste!!

I've been using Fluorodine toothpaste for 5 years! It could be a while, before I go to the dentist and they always say... " you haven't been here for a while, amazinggg! there is hardly any tarter!!" I love this toothpaste. The best thing is as a chronic tea drinker (I drink 4-5 cups a day), Fluorodine toothpaste prevents my teeth from yellowing. Really keeps your teeth clean.
