Sodium bicarbonate: How does baking soda help my smile?

Continuing with our ingredient list, another important component in a toothpaste is the abrasive. It is essential to remove stains from the tooth surface and improve brushing efficiency.


The most common abrasives in commercial toothpastes such as hydrated silica, calcium carbonate, alumina and perlite are highly abrassive. This can cause damage to tooth enamel, as well as gingivitis (gum inflammation) and the consequent tooth sensitivity. All of these diseases may happen even if those abrasives are used in very low concentrations.

In contrast, there is the sodium bicarbonate (NaHCO3), commonly known as baking soda. This compound has been considered one of the least abrasive materials, if not the least abrasive, for a long time. This allows its use in higher concentrations to fulfill the function of cleaning the enamel, without damaging its structure or damaging our gums.


The ideal toothpaste should be abrasive enough to remove surface stains without damaging tooth enamel. This is why our TeethTabs contain sodium bicarbonate as the abrasive component. Its safety (it is not toxic if ingested), low abrasiveness, biological compatibility (our body also contains it) and low cost make it an excellent ingredient in a toothpaste.


Sodium bicarbonate in your toothpaste promotes the removal of bacteria-biofilms involved in the development of gingivitis (some bacteria can produce a "layer" or "film" over surfaces such as tooth enamel). In addition, sodium bicarbonate is also a bactericide against most periodontal pathogens.


Sodium bicarbonate also acts as an acid-buffering agent which favors the alkalization of the oral environment (which becomes acidic after a meal). This alkalization favors the remineralization and strengthening of tooth enamel together with calcium phosphate and xylitol.


Finally, its quick removal from the gingival sulcus (where the tooth "joins" the gum) will prevent the development of sensitivity and the build-up of tartar, giving you a clean and healthy smile.


Toothpastes containing sodium bicarbonate are appropriate for patients at high risk of developing tooth erosion because they have lower abrasive levels. This minimizes abrasive wear on softened or eroded tooth surfaces. They are also appropriate for patients with exposed surfaces with symptoms of dentin hypersensitivity.


Sodium bicarbonate's only disadvantage is its salty taste. However, as you have noticed if you've already tried our TeethTabs (and if not, we invite you to try them), we have achieved the perfect formulation: we have managed to balance the benefits and flavor of sodium bicarbonate with xylitol, a natural sweetener and antibacterial agent, together with the essential oils which give the fresh flavor and aroma to each of the TeethTabs in its three flavors: Mint, Spearmint and Tropical (fresh mandarin).


The sodium bicarbonate together with calcium phosphate in our TeethTabs, will keep your teeth free of tartar and safe from enamel wear.


We invite you to try and see for yourself that, in addition to their pleasant taste and smell, the TeethTabs will give you the cleanliness you need to maintain a healthy smile every day.
