Whitening your teeth is something many people do because it makes them happy. Whiter teeth can make you feel more confident about your smile. Whiter teeth are also associated with a more youthful appearance. Another reason some people whiten their teeth is that they have older crowns that now appear lighter than their natural teeth and now there is a mismatch. So whitening can also help blend in dental work. One more reason people may not think of when considering teeth whitening is that most whitening gels are also fortified with fluoride and minerals that are good for your teeth and can help to make them stronger. These fortified whitening gels will only be sold at dental offices and are only used with custom whitening trays. So go see your dentist!!
