How does whiten teeth 0.15 percent w v fluoride ion?

Answer 1

fluoride does not whiten your teeth. when bacteria naturally found on your teeth eat the leftover sugars in your mouth, they release acid which dissolves the enamel. when enamel rebuilds from the tooth and your saliva, it can be reformed with or without fluoride. the enamel formed with fluoride is many times stronger than the enamel without it. it has nothing to do with the color or your teeth.

the whitening of your teeth can be done by abrasives such as baking soda or silica (fine sand). this grinds down the outer layer of your tooth which is what is stained the most, scrubbing away the stains while damaging the tooth. like scrubbing your dishes with baking soda to get them clean.

you can also use something like hydrogen peroxide. this gets into the small pores in your teeth and gets to stains deeper within the tooth, then dissolving them away. of course, it dissolves away some of your tooth in the process.

to whiten teeth, you can get an abrasive toothpaste with hydrated silica and baking soda to clean the outer layers. make sure this toothpaste has Sodium Monofluorophosphate instead of the regular Sodium Fluoride - it works better that way when calcium abrasives are present. Make sure you get a high content of it in the toothpaste, as scrubbing is damaging to your enamel and it needs to be rebuilt fast.

Then use a mouthwash with hydrogen peroxide and fluoride in it to rinse. that will get deeper under the surface of the tooth. Do not rinse with water afterwards - the fluoride needs to stay on your teeth and "work" awhile. don't eat/drink a couple of hours after the rinse.

You may get sensitive teeth due to all the bleaching and scrubbing. that's your body telling you you're doing so damage to the teeth. to minimize that further, you can get a high-content fluoride gel to use after the mouthwash. Colgate makes it - just get the highest %fluoride you can find. The gels will likely use Stannous Fluoride. That can damage dental work, so don't brush with it - just get it on your teeth w/o scrubbing and leave it on a minute. then spit, and don't rinse.

Understand using toothpaste and rinses to whiten will take years for results. If you're looking for something more immediate, go to a dentist, pay about $80/tooth, and have them bake your teeth in hydrogen peroxide. it'll remove the stains right away.
