The cheapest way to clean brown teeth without going to the dentist?

Find the cause: I would advise you to find the reason for the brown teeth and eliminate it. Example: long course of tetracyclin antibyotics, smoking, too much fluor in the water. I have seen a lot of brown teeth from overbrushing the teeth with a lot of tooth paste which has a lot of abrasive.In that case the enemal of the tooth gets worn off and the dentin underneath starts showing and it has browner color.

Whitening is...: Whitening is available in many forms. And over the counter is one form. With this being said, white does not mean healthy. Please see a dentist and get regular dental care.

None>.: If your teeth appear brown and it is not just stain but the tooth shade itself you must bleach your teeth. Over the counter bleaching like crest white strips will not give a good result with brown teeth. You can get them professionally bleached at your dentist for a reasonable fee. We are running an august special for $200. This will give you the best result.

Baking soda: Look up using baking soda (aluminum free) mixed with hydrogen peroxide.

Prophylaxis : Please get a consult with a dentist before you consider any whitening proceedure . You could cause harm to your teeth and gums if you have decay or gum inflammation. Keep in mind that coffee, tea, red sauce., red wine etc all cause stain on teeth.
