Abbrasives! Beware, these so called whiteners will typically destroy the enamel coating on your teeth, exposing them to infections and eventaully your teeth will rot.\nWhen you brush with these abbrasives it is similar to brushing with sand, you are litteraly grinding the surface of your teeth off!

Hi, \n\nThe only way you will be able to whiten your teeth properly is to have them bleached professionally at a dentist. The stuff sold in the shops does not contain enough peroxide (the active ingredient) to remove anything but a little suface staining.You need to have at least 10% peroxide and this strength is only legally available to dentists in the UK . \n\n Bleaching, when done properly does NOT damage the enamel of the teeth, any sensitivity is usually only temporary and can usually be overcome by using a Sensitive toothpaste and fluoride mouthwash.\n\nI have had quite a few patients have it done, men and women of all ages (mostly over 40 surprisingly) and we have had some really good results.\n\nTo do home bleaching supervised by a dentist costs around £350 but gets fantastic results. You wear two bleaching trays for a couple of hours a night for approx 2 wks depending on lightening needed.\n\nYou can also have speed whitening done at the dentist in 1 hour and at around £650, but beware, if your teeth are not isolated properly this can make your teeth and gums very sensitive! better to do it gradually over a couple of weeks when you get the same results anyway. The laser light does not really do anything anyway, it just makes you think you are getting value for money !\n\nIf it is just surface staining I advise my patients to use a toothpaste containing Bicarbonate of soda and and electric toothbrush (you can get them as cheap as £12 now) this can work wonders too. Also a visit to a Dental Hygienist for a professional scale and polish can make a big difference .\n\nHope this helps

Coffee, hot chocolate, and smoke are some major factors in staining teeth.  Also, aging is a factor.  The only way to keep your teeth from yellowing is to bleach them at a dentist office once in a while.  What a difference it makes!!

hydrogen peroxide is a reducing agent ie it removes oxygen from compounds when teeth are exposed to food particles that get stuck they form a film of yellow matter that cannot be removed hydrogen peroxide bleaches ie reduces the yellow matter it also kills bacteria by the same way by suffocation but too much of a good thing is bad and hydrogen peroxide with its mild acidic effect erodes the teeth over time

My dentist said that if you have no money for fancy whiteners you can make a paste of peroxide & baking soda and apply it to your teeth for a short time.  Whatever remedy you decide to use make sure it is short-time because you don't want to weaken the enamel; and remember to try to stay away from foods that are colored such as coffee, soda etc. or you might as well not try to bleach them.

Sodium hypochlorite is a strong oxidizer. In water, it partially splits into the sodium cation Na+ and the hypochlorite anion ClO−, while a substantial portion hydrolyses into sodium hydroxide and hypochlorous acid. The oxidizing power of the latter and of the hypochlorite anion cause the bleaching effect.\nyea you're right infact soduim hypochlorite is callec bleach.despite the fact that there are other bleaching agents.

There aren't any and none of them are approved by the ADA.  The best way to whiten your teeth is by going to see your dentist.  The only whitening systems for home use that have been approved by the ADA are Colgate Platinum Daytime Professional Whitening System, Opalescence, and Nite White.  All of which can only be obtained from your dentist.

Hydrogen Peroxide and baking soda....form a paste and brush your teeth with it, do it for two weeks, and it will help.  P.S. If you drink coffee, then don't.

The only way to get your teeth super white is by bleaching or veneers. Whitestrips do not wear tooth enamel away. I'm a licenced dental hygienist and I use them all of the time. They do cause sensitivity though but it goes away. That is the cheapest route. The next step up is bleaching trays and in office whitening which is expensive and not worth the cost for the instant gratification. Whatever you do do not go crazy with whitening toothpaste.  This really does wear down enamel over time, esp. if you are scrubbing because you don't like the tooth color. All that makes toothpaste"whitening" is just abrasive stuff. Then you scrub off the enamel to expose the dentin which is naturally yellow in color. Sorry to ramble but I see this every day.

The best way is to use a combination of techniques.  Crest Preminum Plus whitening strips work good, but can cause sensitivity.  Dentists use hydrogen peroxide gel to bleach teeth.  Toothpastes with hydrogen peroxide will aid in making your teeth shine.  My recommendation is to use Arm & Hammer whitening toothpaste, Listerine whitening mouthwash with Crest Premium Plus strips during the day and Crest Night Effects at night to make your teeth shine their best.

B Vitamins.  Not sure which mix exactly. Google B Vitamins though.

anything colored is going to pigment your oral cavity, but it won't last long.  Crest Pro Health is one of the best mouth rinses to use because it does not contain alcohol.
