Carbonated drinks have always been a favorite among kids. It’s easy to see why: they’re refreshing, sweet, and the perfect companion to a pizza with friends or a burger at a fast-food restaurant after a night at the movies.
On average, people worldwide drink roughly 30-40 liters of sugary or carbonated drinks per year, with the highest consumption among younger age groups. Such widespread consumption makes it clear that the potential damage from these beverages affects everyone, but especially children and teenagers.
The link between soft drinks and overall health problems has been well known for years: they can contribute to chronic conditions like diabetes and obesity. However, their impact on oral health should not be overlooked.
But why are these drinks so harmful to our teeth, and why is the effect even more pronounced for young teeth?
How Much Sugar Is in a Can of Coke?
First of all, these drinks contain a huge amount of sugar. A single can of cola, for example, has over 35 grams of sugar – equivalent to seven sugar cubes. The bacteria responsible for tooth decay love it, and as they metabolize sugar, they produce acids that attack and weaken teeth by eroding enamel.
You might think that “light” or sugar-free versions of kids’ favorite drinks are safer – but that’s not the case. These beverages are naturally acidic even without sugar.. Over 90% of soft drinks have a pH below 4.0. When the oral pH drops below 4.0, acid begins to dissolve the tooth’s surface structure in an irreversible process called dental erosion.
The acid attack lasts for about 40 minutes after each sip – the time it takes for healthy saliva, rich in bicarbonate, to restore the mouth’s natural pH.
Since soft drinks are often consumed in large quantities (think of the giant cups sold at cinemas or fast-food restaurants), this exposure can last even longer, putting teeth at prolonged risk.
If this is dangerous for adults, it’s even more so for children and teens. Their enamel is not fully developed yet, making their teeth more susceptible to acid attacks. That’s why kids often have higher rates of cavities and dental erosion than adults.
The great news is that fizzy drinks are not a necessary part of a child’s diet. In fact, they can – and should – be eliminated entirely without any problem.
Healthy Alternatives to Sugary Drinks
As is often the case, teaching good oral hygiene and healthy eating habits is the best way to keep a bright, healthy smile. How can we encourage kids to cut back on fizzy and sugary drinks?
We know that proper hydration is essential for overall health—but not all drinks are equal! Beverages containing caffeine, like cola and other popular soft drinks, can even have the opposite effect, accelerating dehydration. Another good reason to limit them!
The first rule for protecting children’s oral health is to keep fizzy drink consumption to a minimum, favoring water or age-appropriate herbal infusions to avoid sugars and acids that can damage enamel.
Straws: A Simple Trick
Sometimes it’s okay to make an exception – after all, making fizzy drinks completely off-limits can make them even more tempting!
If we allow a small treat, it’s best to limit it to one glass, ideally during meals, when saliva production is higher and can help protect teeth.
Using a straw can provide an unexpected benefit: it keeps the liquid away from the teeth, reducing contact with sugars and acids and lowering the risk of damage.
Fizzy Drinks and Oral Hygiene: Your Best Allies
The best practice is always to reduce the time teeth are exposed to acidic and sugary drinks and to brush teeth immediately afterward. When brushing isn’t possible, children can rinse their mouths with natural bicarbonate-based sprays to quickly rebalance oral pH – or, if unavailable, simply rinse thoroughly with water.
This helps dilute acids and remove sugars, preventing bacteria from feasting. As soon as possible, brushing and using protective sprays is recommended to remove any remaining sugar and prevent cavities.
Since every sip of a fizzy drink alters the mouth’s environment for many minutes, it’s advisable not to sip slowly over long periods. This minimizes contact between acid and teeth, reducing the risk of dental erosion.
Finally, never allow fizzy drinks right before bedtime. At night, saliva production decreases naturally, and teeth aren’t brushed for hours. This creates an acidic environment harmful to teeth and gums. If kids drink cola or orange soda before bed, potential damage is even greater.
