How can I whiten my teeth quickly?
About 18 percent of people report “usually concealing their teeth in photos,” many due to being embarrassed over the yellow appearance of their teeth. Having great teeth is very important in our culture today — hence the growing number of people using white strips and whitening paste as part of their oral care at home or turning to professional in-office whitening treatments. Your teeth are one of the first things people notice; they’re a sign of health as well as confidence. When making a first impression, most worry about having aged, crooked or discolored teeth, which can send a signal that you don’t really care about yourself.
