Here are some tips that you can use to whiten that yellowish teeth. :-)

Baking Soda:
We all know that once you ran out of toothpaste, you can use salt as an alternative toothpaste. But salt is abrasive that can damage your teeth. You can use Baking Soda instead, though baking soda is also abrasive but not as abrasive as salt. Just use Baking Soda with or without toothpaste and make sure you rinse your teeth properly to avoid residue that can damage your teeth.

Hydrogen Peroxide:
Apply this solution to your teeth may help whiten your littler pearlies. You can also gargle Hydrogen Peroxide as a mouth wash replacement but try not to over do it as it can iritate your gums and inner lining of your mouth. Plus make sure you use the 1.5% hydrogen peroxide solution any strong will be harmful.

Strawberry:
Of all the whitening solution this is my favorite. Since you get to eat these tasty fruits and you have an excuse you eat a lot!! :) It would be a waste to use strawberries as your toothpaste. So just eat these tasty suckers and wait for atleast 20 minutes before you brush your teeth. The acid would soften the enamel of your teeth and brushing immediately will damaged your teeth.

But if you are one of the hopeless and born with a yellowish teeth like me, then don't let a perfect picture ruined by that yellowish teeth. You can use PaintShop Pro Photo X2 Ultimate to whiten your teeth in the photos that you have taken. If you do not have the program you can download the link at PaintShop Pro Photo X2 Ultimate product page or this link: Free Trial - Corel Paint Shop Pro Photo X2 Ultimate.

Here you see a photo that I got from the internet, see that perfect smile? ;)


We can still enhance this picture by whitening the teeth.

To whiten teeth
1. On the Tools toolbar, choose the Makeover tool.


2. On the Tool Options palette, choose the Toothbrush mode.


3. On the Tool Options palette, adjust the Size and Strength control as desired.


Note: The higher settings produce more intense whitening but may also produce an unnatural appearance.

4. Click directly over the teeth, you see that the color will become whiter as you click on the teeth in the image.


If the teeth are separated or partially obscured, you may need to apply this tool to each tooth individually. You may need to zoom in to clean that hard to reach teeth... hehehe

Note: The Toothbrush mode of the Makeover tool works only with color photos.
