Over the last few years, I have tried MANY whitening systems. The ones I have used the most are: Crest 3D Whitestrips, Gel & Trays (from dentist), and Pro Light.
HOWEVER: My favorite will be the Crest 3D Whitestrips. You buy it, tear off the plastic wrapper, set a timer for the time specified, put the strips on your teeth, and wait. It's the easiest, fastest, and most comfortable for my teeth. The Pro Light was fun, but was a hassle due to the fact that each whitening session lasts 2 minutes and you have to keep redoing it for 45 minutes. The trays from the dentists were good, BUT the gel made my gums white, extra sensitive, and tasted the worst in my mouth. SO. Crest 3D Whitestrips has my stamp of approval, and I highly recommend whitening your teeth with their products. White teeth improves any smile: straight or scraggly. A person's smile should be their favorite feature.
