When you think about sugary drinks—like soda, sweet teas, flavored coffees, or energy drinks—you probably think about cavities. Most people know that sugar damages teeth. But did you know that new research shows these drinks could raise your risk of something much more serious—oral cancer?

A recent study published in JAMA Network Open found that women who regularly drink sugar-sweetened beverages have up to five times higher risk of developing oral cavity cancer—even if they don’t smoke. This is a shocking discovery because oral cancer has long been linked to smoking and heavy alcohol use. Now, it seems our daily habits with sweet drinks may also be playing a major role.

The Hidden Danger in Everyday Drinks

Let’s be honest: sugar-sweetened drinks are everywhere. Grabbing a soda with lunch, an iced caramel latte in the afternoon, or a sports drink after the gym feels harmless. After all, they’re sold on every corner and marketed as refreshing pick-me-ups.

But here’s what most people don’t realize:

• A single can of soda can contain 10 teaspoons of sugar.
• The bacteria in your mouth feast on sugar, producing acid that eats away at enamel.
• Over time, this doesn’t just cause cavities—it creates chronic inflammation and cell changes that may increase the risk of cancer.

It’s not just soda, either. Sweetened iced tea, “fruit” drinks with little real fruit, energy drinks, and even fancy coffee beverages can all pack a sugary punch.

Why This Matters for Non-Smokers

For years, many non-smokers felt “safe” from oral cancer because they avoided tobacco. But the JAMA study shows that sugary drinks may be their hidden risk factor. The surprising part? The increased risk appeared even in women who had never smoked.

That means even if you’ve done everything right—no smoking, no chewing tobacco—you could still be putting your mouth at risk with the drinks you sip every day.

Think about this: if a woman drinks a sugary beverage daily for years, her mouth cells are constantly exposed to sugar and acid. That’s like bathing your teeth, gums, and tongue in fuel for bacteria, which can lead to long-term damage.

A Patient Story That Stuck With Me

I once spoke to a patient who admitted she drank three sodas a day for nearly two decades. She brushed regularly and thought she was keeping up with her oral health. But she began noticing white patches inside her cheek and on her tongue that didn’t go away. Thankfully, we referred her for a biopsy, and while it wasn’t cancer, it was a pre-cancerous condition.

The shock on her face when she learned that her soda habit—not cigarettes—had led to this was unforgettable. She told me, “I thought I was safe because I never smoked.” Stories like this remind us that the risks are broader than most people think.

The Bigger Picture: How Sugar Affects the Whole Body

The link between sugar and oral cancer is only part of the story. Sugary drinks have already been tied to:

• Obesity
• Type 2 diabetes
• Heart disease
• Liver problems

When you drink these beverages regularly, you’re not just risking your teeth—you’re stressing your entire body. That’s why so many health experts now compare sugary drinks to cigarettes in terms of long-term danger.

Simple Tips to Cut Back on Sugary Drinks

The good news is, you don’t have to give them up overnight. Here are some realistic steps:

1. Start small. If you drink two sodas a day, cut back to one. Then swap that one for flavored sparkling water or unsweetened iced tea.
2. Rethink your coffee order. Instead of a caramel latte, try coffee with milk and just a small amount of sugar.
3. Keep water visible. Carry a reusable water bottle. Sometimes we sip sugary drinks just because they’re handy.
4. Check labels. Drinks marketed as “healthy” (like certain smoothies or teas) can have as much sugar as soda.
5. Reward yourself differently. If you normally grab a sweet drink for a “treat,” switch to something non-food related, like a short walk or a new playlist.

Your taste buds can adapt. Within a few weeks, you may find that regular soda tastes too sweet—a sign that your body is resetting.

What This Means for Your Dental Health

At Riverside Dental Center, we see firsthand how sugary drinks affect patients. Cavities, enamel erosion, gum inflammation—it all adds up. But what’s harder to detect on your own are the early warning signs of oral cancer.

These can include:

• Sores in the mouth that don’t heal
• White or red patches inside the cheeks or tongue
• Unexplained bleeding or pain
• A lump or thickening in the mouth or throat

Catching these early makes a huge difference. The survival rate for oral cancer is much higher when it’s detected in its early stages.

Why This Research Is a Wake-Up Call

It’s easy to think of soda or sweet tea as “just a drink.” But this research shows it’s time to think differently. Sugary beverages aren’t just empty calories—they could be silent triggers for serious health problems.

We’re not saying you can never enjoy a soda at a ball game or a sweet coffee with friends. Life is about balance. But knowing the risks helps you make choices that protect your health for the long run.
