Combine 2 teaspoons (10 ml) of hydrogen peroxide with 1 teaspoon (6 grams) of baking soda and gently brush your teeth with the mixture. Limit the use of this homemade paste to a few times per week, as overuse can erode your tooth enamel.

Read More »Share on Pinterest CRIENE IMAGES/Twenty20 Teeth whitening has become more popular in recent years as more products come onto the market. But many of these products can be quite expensive, leading people to look for cheaper remedies. The most affordable way to whiten teeth at home — and the remedy supported by the most significant body of research — is the main ingredient from most teeth-whitening products: hydrogen peroxide. What does the science say? Here’s what you need to know: Most hydrogen peroxide bottles you can buy at a drugstore or grocery store are diluted to around 3 percent. The amount of hydrogen peroxide in commercial whitening treatments varies and can be as much as 10 percent in some products. But studies suggest dilution is a good thing when it comes to using hydrogen peroxide for teeth whitening. Concentrations that are too strong can damage the enamel, or outer coating, of your teeth. In a 2007 study, scientists applied diluted hydrogen peroxide solutions of 10, 20, and 30 percent to human teeth that had been extracted for varying amounts of time. They found that higher concentration solutions caused more damage to teeth, as did keeping the teeth in contact with hydrogen peroxide for a longer amount of time. This suggests that low-concentration treatments of hydrogen peroxide, applied for shorter periods, have the least potential to damage your teeth. According to a 2004 study, scientists found that a 5 percent hydrogen peroxide solution was just as effective as a 25 percent solution at whitening teeth. But to achieve the same level of whiteness, one would need to whiten teeth with the 5 percent solution 12 times to get the same level of whitening as one time with the 25 percent solution. This means if you’re using short, low-concentration treatments, you’ll have to perform more treatments to achieve your desired whiteness. How do you use hydrogen peroxide as a teeth whitener? There are two ways: swishing it around your mouth, or mixing it with baking soda and setting it on your teeth as a paste before rinsing. Using hydrogen peroxide as a rinse Mix equal amounts hydrogen peroxide with water, such as 1/2 cup to 1/2 cup. Swish this mixture around your mouth for about 30 seconds to 1 minute. Stop and spit out the solution if it’s hurting your mouth and try not to swallow any of the mixture. Using hydrogen peroxide in a paste Mix a few teaspoons of baking soda in a dish with a small amount of peroxide. Start to mix the soda and peroxide with a clean spoon. Keep adding a little bit more peroxide until you get a thick — but not gritty — paste. Use a toothbrush to apply the paste to your teeth using small circular motions. Brush for no longer than 2 minutes. Then, thoroughly rinse off the paste by swishing water around your mouth. Make sure you remove all of the paste before moving on with your day. Are there any side effects? Several studies suggest that using hydrogen peroxide — whether in a commercial product or at home — can cause damage to your teeth. The risk of damage increases when you: use a very strong hydrogen peroxide solution, such as concentrations above 3 percent

Read More »leave the hydrogen peroxide in contact with your teeth for a long time (longer than 1 minute if swishing or 2 minutes if brushing as a paste) apply the hydrogen peroxide to your teeth too many times (more than once daily) Talk with your dentist before applying any hydrogen peroxide to your teeth to determine which strategy and application schedule makes the most sense for your situation. Teeth sensitivity is perhaps the most common side effect of hydrogen peroxide use. You may find consuming hot or cold foods or liquids unpleasant after a peroxide treatment. Avoid doing so for as long as you experience pain. This happens because peroxide can cause significant damage to the protective enamel of teeth if used too often or in too-high concentrations. More serious side effects of hydrogen peroxide whitening include inflammation of the teeth roots in the gums. This problem can lead to secondary issues, such as infection, which can be expensive to treat.
