Nowadays there are plenty of ways to achieve wonderful white teeth in a few days. Professional teeth whitening treatments are generally quite expensive and some of these may use different bleaching agents that may be harmful to tooth enamel. But why spend fortunes on costly procedures, when there are some amazing homemade methods, which help you to obtain attractive white teeth. While some home practices can be dangerous when used incorrectly, others are completely safe and simple to be used right at home. Read our tips below and save yourself some time to give your teeth the proper care and attention for sexy, bright smile. 
Crunchy Vegetables
Crunchy vegetables, such as carrots, cucumbers, celery or broccoli are excellent choices to naturally whiten your teeth. Due to their rough surface, these veggies work like tiny toothbrushes. Thanks to their natural abrasive properties, crunchy vegetables scrub away food residues, stains and spots from the surface of your teeth, making them healthier and stronger.
Strawberries
Another great natural and costless home remedy to achieve white teeth is composed of mashed strawberries. The malic acid found in this wonderful mixture works as an astringent, helping you to get rid of discoloration. Although be careful while brushing your teeth with strawberry paste, since the seeds can be harmful to your enamel and gums. Use gentle motions and make sure you brush your teeth right after the procedure. For an increased effectiveness, you can add a little baking soda to the strawberry paste to clean your teeth in an all-natural way, as well as to remove stains caused by dark beverages such as coffee, sodas or red wine. Baking soda works great to kill the bacteria in the mouth, which is the major cause of bad breath and plague. Mash the strawberry, until you get a pulp, then add 2 pinches of baking soda and blend the mixture well. Distribute the paste onto your teeth, using a soft toothbrush to avoid irritations and damages to your gums. Brush it gently all over, then rinse your mouth well to remove all the residues of the strawberry mix. Although it is a cheap and effective way to easily achieve a bright, white smile, never apply this paste too often, since the acid may cause damages to your gums as well as the enamel of your teeth.
Lemon Juice
Lemon juice is one of the most popular and frequently used methods to whiten teeth, although it is also the most dangerous technique as well. The reason behind is that the citric acid found in this fruit deprives the enamel of your teeth from its calcium content, making it vulnerable and more prone to faster deterioration. Frequently using lemon juice to obtain whiter teeth, can lead to serious damages as it destroys the teeth enamel until there is no way to treat the problem. If you still decide to try out this method, ensure the safety of your teeth by applying only a few drops of lemon juice on your toothbrush and making sure you brush your teeth carefully.
While these natural techniques used for teeth whitening are simple, painless and costless, and the ingredients can be easily purchased from your own kitchen, you have to pay special attention to use them only once in a while, so that you can avoid damaging your teeth and you can maintain their health and integrity. One of the best ways to achieve a bright smile is to brush your teeth after each meal. However, if you want faster results, you can also opt for a professional teeth-whitening product recommended by your dentist.
