Dental professionals often repeat their advice to avoid or limit sugary drinks. Bacteria that are naturally found in the mouth feed off sugar, and their byproducts can lead to tooth decay, cavities, and pain.
Some people heed this warning and switch to sugar-free or low-carb versions of their favorite caffeine boosters. But are sugar-free energy drinks bad for your teeth?
Acid Attack
Did you know that tooth enamel is the hardest surface in the human body? It’s made of tightly packed mineral crystals that band together like a fortress to protect the rest of the tooth. As tough as enamel is, acid in sodas, fruit juices and more have the power to dissolve those mighty materials, causing holes.
Holes caused by acid are entry points for the bacteria to become entrenched. Remember how we mentioned bacteria have a byproduct that leads to tooth decay? That byproduct is more acid! This means acidic drinks have a multiplying effect on tooth damage.
Acidic Drinks by the Numbers
Are sugar-free energy drinks acidic? Yes! But just how bad are they?
Below are the pH levels of some common beverages. Any number below 4.5 indicates a drink could erode your tooth enamel. The lower the number, the more potential a drink has to damage your teeth. You’ll see below, only two drinks on this list are considered non-threatening to your tooth enamel.
- Homebrewed Black Coffee – 5.35
- Dasani Bottled Water – 5.03
- A&W Root Beer – 4.27
- Minute Maid Orange Juice – 3.82
- Rockstar Sugar-Free – 3.39
- Coca-Cola Zero – 2.96
- Rock Star Energy Drink – 2.74
- Country Time Lemonade – 2.72
- Coca-Cola Classic – 2.37
While the sugar-free energy drink is slightly less acidic than its sugar-loaded counterpart, it is still well into the danger zone.
Sugar-Free Energy Drinks and Teeth: Healthy Tips
So, what can you do to combat the hidden dangers of sugar-free energy drinks? Here are some key steps:
- Moderation: Limiting your intake of sugar-free energy drinks limits the exposure to harmful acids.
- Drink milk: Milk and cheese are two tasty options for neutralizing the acids in your mouth after a sugar-free energy drink.
- Rinse: After enjoying an energy drink, sugar-free or regular, rinse your mouth thoroughly with plain water to dilute and wash away the harmful acid. Once the acid is gone, your own saliva starts building your defenses back up.
- Get chewing: ADA approved sugarless gum promotes the continued production of saliva, your tooth enamel’s number one ally.
- Brush in 60: Brushing your teeth is one of the most essential tasks for protecting your teeth, and it’s a great post-meal practice. But watch out! Acidic energy drinks - and even fruits and vegetables like tomatoes and oranges – can temporarily weaken the enamel. A vigorous brushing in that weakened state can actually cause more harm than good. Wait one hour to brush after consuming an energy drink.
Your smile is precious, and leaving it vulnerable to acid is like leaving the gate of your fortress wide open. But by making informed choices and prioritizing proper oral hygiene, you can keep your smile sparkling and healthy for years to come.
