What is Baking soda?

Baking soda is also known as sodium bicarbonate, having numerous applications in various fields. One can easily recognize baking soda, as being the fine white powder with a salty or alkaline taste. Baking soda is often used as a food additive but this is not its only use. The history of baking soda goes as far as ancient Egypt – similar substances were used back then for the painting of hieroglyphics. In more recent times, baking soda was produced for the first time around 1846, by two bakers from New York. Baking soda was made from sodium carbonate and carbon dioxide, as it is made today as well.

Given its high availability, baking soda has started to be used in numerous fields, with the most diverse purposes. Nowadays, baking soda can be used to remove different types of paint, to disinfect certain surfaces, to eliminate fungus from various places and even to extinguish small fires. One of its most important uses is in the kitchen, the baking soda being often preferred as a leavening agent. In the medical field, baking soda has been known to act as a powerful antacid when mixed with water, eliminating the symptoms of indigestion and heartburn. Doctors have also used baking soda in patients with acidosis or those suffering from hypokalemia. Last, but not least, baking soda has been extensively used for personal hygiene purposes – mainly for brushing teeth.

Is it safe to brush your teeth with baking soda?

Baking soda is well known for its whitening effect, so you can use it with confidence for such purposes. Another great benefit of brushing your teeth with baking soda is related to the removal of plaque.

By brushing your teeth regularly with baking soda, you will effectively remove the plaque build up from your teeth. This goes hand in hand with the bright smile – once the plaque is removed from your teeth, you will see that they look whiter. This is because the plaque often leads to a yellowish discoloration of the teeth.

So, brushing your teeth with baking soda will keep you free from cavities and, thanks to its abrasive properties, it will prevent plaque from building up on the teeth, destroying the enamel. You can think of baking soda as a powerful cleanser, with beneficial effects for both the teeth and the gums. In fact, studies have shown that the frequent use of baking soda can improve the pH of the mouth, as it neutralizes the acid production. It also has antiseptic properties, so by using it on a regular basis, you will protect yourself against different infections.

If your teeth have been stained by the different foods or beverages that you eat or drink (tea, coffee and wine are especially responsible for such problems), you can consider baking soda as an efficient solution. Apart from the fact that you will notice an overall improvement in your dental health, you will sleep peacefully at night, knowing that you are protected against periodontal disease.
