This video shows you how to whiten your teeth in the comfort of your own home. You don’t need a lot of equipment to do this at all, in fact, all you need is some bicarbonate of soda and some lemons/limes. She starts by spooning the bicarbonate of soda onto the plate, before she adds the lemon juice. The mixture obviously reacts because it is an acid, but eventually the bubbles reduce enough for you to see the paste. She then places the paste onto her toothbrush and she brushes her teeth.
It is important to note that you do need two toothbrushes to do this and you should only do it once a week as well because if you overdo this then you can damage the enamel on your teeth. This is a great video that you really do need to see for yourself.
