how to whiten my teeth?

This is not the best teeth whitening method.

this is just a tribute

white paint

use a toothpaste.

i dont know if this is a serious question thoguh, i dont think you will find anythin inmediate in your house, unless you are a dentist, i recomend you to use whitening thootpaste but dont use it too often since the chemicals in them tend to weaken the theets

Doge never whitens his teeth.

Here are some useful ideas: http://bone-lust.blogspot.no/2013/06/whitening-bone-teeth-hydrogen-peroxide.html
(You may have to remove your teeth first)

cleaning your teeth 2-3 times a day for 3 minutes, using floss every day and elmex (some special toothpaste for rebuilding your teeth's strengh. I don't know which brands there are in other countries.) every week keeps the dents clean. You can also ask your dentist about what to do.

not-white teeth come from either eating too many sugar-ish (or any other teeth-attacking stuff) things. Also, if you ever fell on your teeth or put them under heavy pressure, they might become yellow, but that is not the normal case.

So in the end, there is no healthy way to get them white again if they were non-white for some time.

Gargle bleach 2 to 3 times a day for at least 2 minutes.

Try to brush your teeth with some salt. After that, cleanse with some water. Take a cup of any kind of alcohol you have in your house and cleanse again. At last, prepare a batch of lemon juice and cleanse again. Hope it work, never tried this.

Try Toilet water

The only thing that really works (according to my dentist) is going to one of them teeth whitening clinics so it will be done professionally. It is not cheap though.
Meanwhile, don't smoke and don't drink tea and brush them daily :)

seriously though just buy toothpaste that helps with secitiviy and whitens the teeth.

Try horse butter.

Use sandpaper. It'll be shining.

I don't know, don't eat cakes.

Are you ready? Be honest.

You can cause root damage by whitening your teeth. I suggest to just wash Your teeth every evening and morning. Whole whitening idea seems pointless to me, because if You care about Your teeth, You wouldn't need to do that. And yes, my parents are dentists.

Best method I found

White chalk.

Using Hydrogen Peroxide as mouthwash but don't use too often .
To brighten teeth you can mash up a ripe strawberry and dip your toothbrush in it - but be sure to rinse thoroughly afterwards, using warm water to which a pinch of bicarbonate of soda has been added, to reduce acidity in the mouth.
Water with salt to strengthen your gums.

Idk ask dentist, they should know.... this not a dentist forum. I might be mistaken what this forum actually is, there are so many weird topics, every topic 150+ comments.

Baking soda is a temp fix that actually wears down your enamel and make your teeth weaker in the long run. For better looking teeth, it mostly comes down to diet and habits.

Wine, coffee, pop, tea, tobacco all yellow your teeth and should be avoided. Just brush regularly and maintain a healthy diet and you should be fine :D.
