1. Baking soda
Baking soda is known as being one of the most effective options for whitening teeth. It’s why you see it added to a number of toothpaste brands. Simply add some to your toothbrush while it is fairly wet and then brush your teeth. Make sure the baking soda is wet enough and not dry as in a very dry state it can scratch your enamel. But once wet, it becomes soft and dissolves. Make sure you don’t use it dry! Also consider trying it as a mouthwash. Add more water to it and swish it around.
Strawberries are rich in vitamin C, which helps to make your teeth whiter. You can do this by crushing a few strawberries and then applying them to your teeth. Let it sit for about 3 -5 minutes and then rinse out your mouth well.
Lemon has a solid bleaching power, many have used it for their hair but it can be used for the teeth as well. Squeeze lemon juice into a small bowl and add some sea salt to it. Grind it down to a pit so you produce a soft paste. Apply that to your teeth and let sit for 3 – 5 minutes. Rinse well. It’s important to rinse this well as you don’t want to let it sit over long periods of time and break away enamel.
4. Hydrogen peroxide
Hydrogen Peroxide can be used quite effectively to whiten teeth. Due to its very mild bleaching properties, it can be put on the teeth topically to help remove stains. Create a 30/60 mix of hydrogen peroxide to water. Use it as a rinse for about 60 seconds and then spit it out.
5. Banana peel
This one is controversial and I personally wouldn’t say this should be your go to option. Some health professionals say it works, while other say it doesn’t. In the end, the gritty surface, which is rich in magnesium and potassium, may polish teeth and helped remove some stains on the enamel. Results vary greatly and given the other options available, it’s probably best to stick with them, but this could work according to some. To do it, simply rub your teeth with the inside of a ripe banana peel for 2 –5min.
