Perhaps you already know that it’s advisable to gargle with baking soda and water when you have a sore throat. Indeed, it’s a mixture that’s highly recommended for this kind of discomfort. Of course, you shouldn’t neglect any treatment prescribed by your doctor.

Furthermore, rinsing with this mixture on a daily basis can help maintain good dental hygiene. In fact, it contributes to the removal of plaque on the teeth, while helping to maintain fresh breath.

Bicarbonate of soda

Sodium bicarbonate is a salt formed by sodium hydroxide derived from carbonic acid, which contributes to the acid and base balance of the body. The chemical formula with which sodium bicarbonate or sodium hydrogen carbonate is represented is NaHCO3.

It’s a whitish powder that creates an alkaline reaction on contact with water and then dissolves completely. It’s easy to find in any type of supermarket.

One of its advantages is that it isn’t toxic when ingested (in small amounts) which is why it’s used as baking powder in the preparation of various desserts.

Apart from its possible use in the kitchen, baking soda offers many other uses. Among these is the maintenance of good oral hygiene.
