It’s not well known, but lemon juice can get you a brighter smile. A mixture of salt and lemon juice makes a fine paste that can be used to brush your teeth and it does wonders for removing stains. It should be noted that lemonade will not produce the same results. Your teeth are too sensitive to the sugar that’s in lemonade and you’ll only wind up with cavities instead of the whiter smile you dreamed about. Most people just find that the taste of lemon juice is hard to overcome, and that is the hardest part of this treatment. If you want truly white teeth, make sure you use real lemon juice squeezed straight from lemons, or you can get juice from a bottle if you must. Some people can’t stand the taste of lemons, but if it doesn’t bother you then use this method each night before you go to sleep.
