well you have to be carefull when buying generic because some do that an ruin your teeth while others don't . also i brush my teeth three times a day and i didnt use anything else but floss,tooth brush, crest tooth paste , and mouth wash and its been a month and my teeth have whitened a lot . but i dont think its bad for teens to use
