The Truth About Citric Acid in Energy Drinks
Share
Citric acid can significantly damage tooth enamel over time, especially with frequent exposure. Here’s how it affects teeth:
1. Enamel Erosion
Citric acid is highly acidic (pH ~2.2 when undiluted) and can soften and demineralize enamel, making teeth more vulnerable to wear and decay. Unlike other acids, it chelates (binds to) calcium in enamel, further weakening it.
2. Increased Sensitivity
As enamel wears down, the underlying dentin becomes exposed, leading to increased tooth sensitivity to hot, cold, or sweet foods.
3. Higher Risk of Cavities
With enamel weakened, bacteria have an easier time penetrating the tooth structure, leading to a greater risk of cavities and decay.
4. Worse When Combined with Sugar & Frequent Sipping
- Soft drinks, energy drinks, and fruit juices containing citric acid worsen the erosion, especially when consumed frequently.
- Carbonation and added sugar further accelerate the damage.
- Sipping on acidic drinks throughout the day prolongs exposure and prevents saliva from remineralizing teeth.
How Bad Is It Compared to Other Acids?
- Citric acid is more damaging than phosphoric acid (found in colas) because it not only lowers pH but also binds to calcium.
- Studies show energy drinks (which often contain citric acid) erode enamel more than soda due to their acidity and added sugar.
How to Reduce Damage?
- Avoid sipping acidic drinks throughout the day.
- Drink water afterward to neutralize acidity.
- Use a straw to minimize contact with teeth.
- Wait at least 30 minutes before brushing after consuming acidic foods or drinks, as brushing too soon can further wear down softened enamel.
How to Prevent Damage Entirely?
- Use alternatives such as Better Energie to be able to enjoy the benefits of energy drinks without the damage to your teeth!
