Easy Teeth Whitening For Any Budget
"How to Whiten Your Teeth at Home:
- To whiten your smile, swap your normal mouthwash with hydrogen peroxide or mix it 1/2 & 1/2 with the mouthwash. Swish the liquid around your mouth and through your teeth for a good minute before spitting it out. Once you spit it out, go ahead and rinse your mouth with water to get the taste out.
- Right after rinsing, brush your teeth using a baking soda/toothpaste mixture. To make this mixture, put a tiny bit of toothpaste into a small cup, and then mix in one teaspoon of the baking soda and half a teaspoon of water. Once the concoction has been thoroughly mixed together and is the consistency of a paste, use it to brush your teeth. Brush your teeth for two minutes, just as you do regularly, and then spit it out. Upon completion, you will have successfully created a whitening treatment comparable to many popular products you’ll find in stores.
- Remember to do the two step whitening process once a week until you have reached the results you want. Once your teeth are good and white, limit yourself to using the whitening treatment once every month or two." It'a a great site, a lot of ideas there!
