Teeth whitening are an expensive deal. You can visit the dentist and he can charge you hundreds of dollars just to get a perfect smile. There are also expensive professional teeth whitening kits that you can buy at the pharmacy. There are a lot of cheap tactics you can use to whiten your teeth and most of it does not need any over the counter whitening kits.
Changing diet or lifestyleThis is the cheapest tactic anyone can follow. A lot of times the color of our teeth is affected by our lifestyle. Things like smoking, drinking coffee or having a cola will make our teeth yellow. So just avoid to the keep that white smile of yours. Your body will also get healthier if you avoid those junks.
Using hard wood ashI do not mean using that black charcoal left over but the white residue that is left after you are done burning it. These residues have something called potassium hydroxide. They can be mixed with your tooth paste to give you whiter teeth.
"Washing" your teeth with baking sodaOne of the proven methods to work all the time is to use baking soda. Other than removing that stain off your carpet, you can also use it to remove the stains off your teeth. You can either apply it with a wet cotton bud that is dipped into baking soda or mix it in with your tooth paste.
Use strawberries for that "juicy smile"Do you know why strawberries have a sour taste? That is because it contains malic acid. Another use of malic acids is to whiten your teeth. You can cut the strawberry in half and use it to scrub all over your teeth. Just remember to brush your teeth after that because it also contains sugar that is bad for your teeth.
All of these methods are cheap and effective even though it takes a long time to see the effect. But even if they are natural and cheap, they will still damage your teeth if done excessively. So use caution and only apply them once or twice a week.
