Teeth Whitening At Home - With Salt!

Why do teeth get yellow?

To figure out how to whiten our teeth, we have to know why they get yellow in the first place. There are several factors that play a part, including genetics, what kind of food and drink you consume, and how well you practice oral hygiene. A tooth is made up of 4 tissues-enamel, which is the strong white covering that protects the tooth, dentin, which supports the enamel and is a hard yellow material that carries nerves, pulp, which is at the center of the tooth and contains blood and lymph vessels, and cementum, which covers the root of the tooth.

The enamel and dentin is what play the biggest role in color. Certain food and drinks will directly stain the enamel, yes, but over time the two biggest culprits are the nasty food and drink that actually break down the enamel, and weakening enamel as we age. As the enamel breaks down, it reveals the yellow dentin underneath. These remedies will focus on whitening teeth that have already lost some white enamel, but it’s also good to keep in mind that doing things to strengthen enamel is just as important so you can keep it from breaking down further. An ounce of prevention is worth a pound of cure (or whitening!)

1. Baking Soda and Lemon Juice Paste

Baking Soda isn’t a shocker here. Sodium bicarbonate (its official name) is mildly abrasive; gently scrubbing away surface stains to return teeth to a whiter shade. It’s also very alkaline (the opposite of acidic) so I would think if you have a very acidic mouth or eat a lot of acidic food, it could help balance out the Ph, which would be useful as acid breaks down enamel-this is strictly speculation on my part. It will also reduce the acidity of the lemon juice, which acts as a natural bleach of sorts. I use a mixture of baking soda and water on some days, and use the lemon juice on others, as I don’t want to overdo it.
You will need…
-Several teaspoons of baking soda
-Enough lemon juice or water to form a paste
-A toothbrush
