وداعا لاصفرار الأسنان

DO start with baking soda. Sodium bicarbonate is a very effective long-term tooth whitener – it’s not harsh, but it will gradually polish your teeth to their best natural shade, breaking up stains from coffee, tea, and wine. It’s good to do once every couple of weeks, and it’s a great way to maintain the upkeep of your natural teeth whitening procedure. To begin whitening with baking soda, simply do this: combine a teaspoon of baking soda with just a drop of water to make a paste, then brush with it. You shouldn’t do this if you have braces or anything else with orthodontic glue, as baking soda can work to dissolve it.
DON’T use lemon. This is a tricky one, because many sites recommend it as a quick solution. Yes, it’s a fruit, which does seem “natural,” but lemon is a powerful acid and will destroy the enamel of your teeth. If someone has told you about this, correct them and recommend one of the other tips instead! The same goes for other fruit solutions, like strawberry paste. Brushing with fruit is a disaster for your teeth.
