The tough enamel covering our teeth is largely made up of a mineral called hydroxyapatite – which is composed of calcium and phosphate ions arranged into rod-shaped crystals. But molecules of food and drink can become lodged between these crystals, discolouring the teeth.
As peroxide is an oxidising agent it ‘steels’ electrons from the molecules staining the teeth, disrupting the chromophore – which gives the molecule its colour – in the same way bleach cleans stains from clothes. The video explains that fastest results will come from a trip to the dentist.
Way to brighten your teeth:
- 1 tbs fresh lemon juice
- 1 tbs baking soda
Make a paste out of the baking soda and lemon juice and leave the paste on your teeth for two minutes only. Make sure you don’t put it for more than two minutes as the lemon is acidic.
Gargle after the two minutes and you will see the difference on the first go.
