It is common knowledge that lack of proper care to teeth can cause them to change color to yellow or brown. What most of us don't know is that yellowing of teeth does not necessarily mean that you are not taking good care of them. Most of the things we eat and drink directly affect our teeth color. The enamel gets stained when we eat. Some foods stain the enamel more than others, while some actually work on the enamel to give you that white color you crave. Crispy fruits like apples are such foods that will do your teeth a lot of good. They are abrasive which means they will polish the enamel to remove stains. For some of us who have noticed a change in color of our teeth, we need a more hands-on approach. Baking soda and lemon juice make a mean mix to restore white color to the enamel. When they are mixed, they form a paste which you can apply to teeth and brush thoroughly with a toothbrush. Needless to say, this method may be harmful to your teeth if used too regularly because the abrasive effect may damage your enamel. The baking soda(sodium bicarbonate) is responsible for removing stains while the lemon juice(citric acid) gives the teeth a bleaching effect. Instead of spending those big bucks on doctors' appointments, give this homemade remedies a try. Do you have any methods of your own to keep your teeth sparkling?
