Flavoured Water: Not as Safe for the Teeth as You Think

Water being poured inside a glass

Ever since experts told us to drink at least eight glasses of water daily, we have been trying to find ways around it.

So we turn to flavoured water to keep us going throughout the day. This may seem like a healthy way to stay hydrated while avoiding soda, juice, and other sugary drinks, but flavoured water presents a problem of its own: dental damage.

The Acidity of Flavoured Water

The problem with flavoured water — sparkling or still — is that the flavour essences cause significant tooth erosion. Other than leading to less desirable-looking teeth, dental erosion also leaves the dentin exposed and could lead to tooth decay. ‘Tooth decay occurs when acids in your mouth dissolve the outer layers of your teeth’, shares a dentist in Wimbledon.

Containing mostly citric and other fruity acids, the beverage causes incremental dissolving of the enamel on the teeth; over time, this can affect their structural integrity, making your pearly whites prone to sensitivity and cavities.

Some brands of flavoured water, on the other hand, get their fizz from carbon dioxide. When carbon dioxide interacts with the mouth, it turns into carbonic acid, making the drink therefore acidic.

Choose Water Instead

Often the label of these drinks will not tell you about the level of acidity. It is a hidden menace, and it is the responsibility of manufacturers to pay more attention to labelling. Until then, however, choose water.


Consult a pH scale. Note that the lower the number, the higher the acidic content in the drink. Plain water has a pH level of seven, and fizzy drinks can be as little as two. While flavoured water still has more neutral pH values than fizzy drinks, water is still the safest choice.

Sure, water cannot bring some excitement to your taste buds as flavoured water does. But no matter how dull and bland, you can never go wrong with H2O.
