HOME REMEDIES FOR WHITEN TEETH - 2
Pineapple Your teeth are covered with pellicle, or a layer of salivary proteins. Your pellicle layer protects your teeth, but it also absorbs pigments from food. This can lead to staining. Your pellicle layer also gives bacteria something to stick to. If bacteria accumulate, they can cause plaque and tooth discoloration. However, pineapple can naturally dissolve pellicle. It contains a proteolytic enzyme called bromelain. Proteolytic enzymes can break down proteins, including those in your pellicle layer. Papaya Papaya, like pineapple, contains a proteolytic enzyme. The enzyme in papaya is called papain. It also breaks down protein, which degrades your pellicle layer. This helps reduce stains and protects against plaque formation. Milk The lactic acid in milk may also lighten your enamel. It’s also said to stimulate the production of saliva, which can help wash away cavity-causing bacteria. Casein, a protein in milk, prevents staining too. Casein helps recruit calcium phosphates to repair cavities and prevent plaque accumulation. One 2014 study also showed that casein binds to polyphenols in tea, which prevents tannins from sticking to teeth and causing staining. Other dairy foods, like cheese and yogurt, also contain lactic acid and casein, and may have a similar effect. How long does it take for foods
