2. Use Apple Cider Vinegar
Apple Cider Vinegar works as a natural antibiotic and teeth cleaner and it also removes stubborn stains on your teeth. It’s especially helpful for removing stains due to coffee and nicotine.
Apple Cider Vinegar contains compounds, including acetic acid, potassium, magnesium, probiotics and enzymes, which kill germs and ‘bad’ bacteria and at the same time promote the growth of beneficial ‘good’ probiotic bacteria.
The key to using Apple Cider Vinegar for teeth whitening is to be consistent, using it for at least a month continuously in order to see the best results. However, be careful, as with all acids it can remove the enamel on your teeth if you brush too hard or use too much. Be sure to rinse your mouth thoroughly after use.
3. Lemon or Orange Peels
Similarly to apple cider vinegar, some swear that using citrus fruits, including lemon and/or orange peels are also a great hack for whitening teeth Like with Apple Cider Vinegar, if you use lemon or orange peel on your teeth, always rinse your mouth thoroughly afterward to be on the safe side.
4. Use Activated Charcoal
Activated charcoal is one of the easiest and most inexpensive ways to naturally whiten your teeth. Crush up one charcoal tablet into a powder. Dip your clean wet toothbrush into it, and brush your teeth as you normally do.
5. Toothpaste, salt, baking soda, and lemon juice
Mix a tablespoon of toothpaste, a pinch of salt, a bit of baking soda, and 4-5 drops of lemon juice in a bowl. Brush your teeth with this mixture for 4-5 minutes. You’ll see the difference after just one use. Use this method every other week.
