I need another method to help prevent plaque from forming on my teeth and a way to whiten my teeth fast?

I already brush my teeth twice a day and use mouth wash but the plaque keeps growing back no matter what

There is no way that you can completely stop plaque. You can use toothpaste that slows it down a little but the best thing is to brush right after each meal. Be careful when you brush though, you don't want to damage your gums or you will have problems later. As for teeth whitening, unless you want to get it done professionally by a dentist, the Crest set that you buy for about $30 does well. You do have to be careful there too, follow the directions, you don't want to erode your enamel.
