Cola often gets the blame when it comes to tooth damage, but dental experts say the truth is more complex. Some fruity sodas may actually do even more harm to your enamel.
Cola is not the biggest culprit
Despite its bad reputation, cola does not necessarily cause more tooth erosion than other fizzy drinks.
Citric acid is harsher than phosphoric acid
Citrus-based sodas often contain citric acid, which is far more damaging to enamel than the phosphoric acid found in cola.
Buffer capacity matters most
It’s not just the pH level that counts. A drink’s buffer capacity determines how long acids linger in the mouth and how much harm they can cause.

Fanta vs. cola
Although both have a pH of around 2.6, Fanta’s citric acid keeps the pH low for longer, making it more erosive than cola.
Sugar-free doesn’t save you
Choosing diet soda doesn’t protect enamel. Even without sugar, the acids still attack your teeth.
Juice isn’t innocent either
Fruit juices, especially those with citrus, can erode enamel just as much – or even more – than a cola.
Carbonation isn’t the enemy
The bubbles themselves are not the problem. It’s the acids and flavorings that lower pH and damage teeth.

Flavored sparkling water is risky
Even lightly flavored sparkling waters can have a lower pH, raising the risk of acid erosion.
Rinse with water afterwards
A simple way to reduce the damage is to rinse your mouth with water after drinking soda or juice.
Use straws the right way
Drinking through a straw placed at the back of your mouth helps limit contact between the drink and your teeth.
Don’t swish it around
Holding or swishing soda in your mouth before swallowing only prolongs acid contact and increases enamel erosion.
