If there is something that we will forever be fond of doing, it is definitely eating our favorite foods every day. Unfortunately though, most foods available in the market can affect our teeth in the most bizarre and unexpected ways.

Some can break our teeth in just a second; some can change their colors from pearly white to something yellowish or worst, black.

You do not need to prevent yourself from grabbing your preferred foods and drinks anymore. We are living in a more advanced world and, luckily, they are already resolutions for the perfectly white teeth.

If you are considering to use peroxide to brighten your teeth, stop it right there. Although it is proven effective, the U.S. Food and Drug Administration (FDA) has alerted the people a long time ago about its adverse effects.
