Bicarbonate of Soda for Oral Care: A Simple Ingredient With a Long History:
Bicarbonate of soda is one of the most familiar ingredients found in homes around the world.
Also known as baking soda or sodium bicarbonate, this simple white powder has been used for generations in cooking, cleaning and personal care. It is also found in a variety of modern oral-care products.
So, what makes bicarbonate of soda useful in oral care?
What Is Bicarbonate of Soda?
Bicarbonate of soda, or sodium bicarbonate, is a white crystalline powder with mildly alkaline properties.
It is widely used because of its versatility and its ability to react with acids.
In oral care, sodium bicarbonate is commonly used as an ingredient in toothpaste and other products designed to help clean the teeth.
Why Is Bicarbonate of Soda Used in Toothpaste?
One of the main reasons bicarbonate of soda is used in toothpaste is its cleaning action.
In a properly formulated toothpaste, sodium bicarbonate can help with the mechanical removal of plaque, food debris and some surface stains during brushing.
It is also a relatively low-abrasivity cleaning ingredient, making it useful in toothpaste formulations designed to clean the teeth while limiting unnecessary abrasion.
The exact performance depends on the complete formulation, including the amount of bicarbonate used and the other ingredients it is combined with.
Can Bicarbonate of Soda Whiten Teeth?
Bicarbonate of soda is often associated with brighter-looking teeth.
It does not bleach the natural colour of teeth. Instead, its cleaning action can help remove some external surface stains.
These stains can build up from things such as tea, coffee and other strongly coloured foods and drinks.
Removing surface stains can make teeth appear cleaner and brighter, but this is different from professional tooth whitening, which uses different methods to change tooth colour.
Bicarbonate of Soda and Acids
Bicarbonate of soda is mildly alkaline and can react with acids.
This simple chemical property is one reason it has become useful in a wide range of everyday applications.
The mouth naturally experiences changes in acidity throughout the day, particularly after eating and drinking.
In toothpaste, sodium bicarbonate can therefore play a useful role as part of the overall formulation. However, it should not be considered a replacement for fluoride or other established approaches to protecting teeth from decay.
Bicarbonate of Soda and Oral Cleanliness
Sodium bicarbonate can contribute to the cleaning performance of a toothpaste.
Research on formulated sodium-bicarbonate toothpastes has found improvements in measures such as plaque compared with some control toothpastes.
However, these results apply to properly formulated oral-care products, rather than automatically applying to loose household baking soda.
Good oral hygiene still depends on regular brushing, cleaning between the teeth and appropriate dental care.
The History of Bicarbonate of Soda
The history of bicarbonate of soda is connected to the much older use of naturally occurring alkaline mineral substances.
Ancient civilisations used natron, a naturally occurring mixture of sodium salts, for purposes including cleaning, preservation and other everyday applications.
Natron is not the same substance as modern sodium bicarbonate, but both are part of the broader history of people's use of alkaline mineral materials.
Modern sodium bicarbonate became increasingly available as chemical manufacturing developed, particularly during the nineteenth century.
It eventually became a familiar household ingredient used in baking, cleaning and a variety of other applications.
Bicarbonate of Soda in Modern Oral Care
Today, sodium bicarbonate can be found in a range of toothpaste formulations.
Its appeal comes from its combination of cleaning properties, mild abrasivity and alkaline chemistry.
The formulation matters. Toothpaste is carefully designed so that its ingredients work together to provide appropriate cleaning performance.
This is why a toothpaste formulated with sodium bicarbonate is different from simply brushing with loose household baking soda.
Bicarbonate of Soda in Your Daily Routine
Bicarbonate of soda can be a useful ingredient in a thoughtfully formulated toothpaste.
For everyday oral hygiene, brushing twice a day with fluoride toothpaste and cleaning between the teeth are important parts of a good routine.
Sodium bicarbonate can complement these habits as part of a complete oral-care formulation rather than replacing them.
From the Kitchen to Your Smile
Bicarbonate of soda may be best known as a kitchen cupboard essential, but its uses extend far beyond baking.
Its simple chemistry, versatility and cleaning properties have made it a familiar ingredient in modern oral care.
From helping remove surface stains to contributing to the cleaning action of toothpaste, bicarbonate of soda has a straightforward role in a well-designed formulation.
Simple. Versatile. Familiar.
Sometimes, an everyday ingredient has more to offer than you might expect.
