When we think of cavities, most of us immediately blame sweets but the picture is far more complex. “Cavities, or dental caries, are caused by bacteria in the mouth that feed on the sugars in our food,
producing acids that erode tooth enamel over time,” says Dr Dheeraj Setia, Founder, Chief Endodontist & Implantologist, The Dental Roots. The type of food you eat, how often you eat it and your daily oral care habits all play major roles in cavity formation.
Sticky and Sugary Foods
Dr Setia, explains, “Sticky and sugary foods are among the biggest culprits.” Chocolates, candies, caramels and even dried fruits like raisins cling to teeth for long periods, giving bacteria more time to grow. He adds that refined and highly processed foods such as bread, chips and biscuits “break down into sugars very quickly and fuel this harmful process.”
Sweetened Beverages
Another major offender, says Dr. Setia, is sugary drinks. “Carbonated beverages, packaged juices, sports drinks and even some so-called ‘health drinks’ often contain high sugar levels and low pH, making them doubly dangerous,” he explains. These drinks not only bathe teeth in sugar but also erode enamel due to their acidity. Frequent sipping throughout the day increases the damage.
Hidden Sugars in Everyday Foods
Not all problematic foods taste sweet. Dr. Dheeraj Setia notes, “Flavoured yogurts, ketchup, energy bars and many breakfast cereals can be deceptively high in added sugars.” Even sauces and condiments that seem harmless can contribute to acid production. He advises patients to read labels carefully to spot “hidden sugars.”
Tooth-Friendly Alternatives
The good news, reassures Dr. Setia, is that there are plenty of healthier options. “Crunchy fruits and vegetables like apples, cucumbers and carrots help stimulate saliva flow and naturally cleanse the teeth,” he says. Dairy products such as cheese and plain yogurt provide essential calcium and phosphates that strengthen enamel. Nuts, whole grains and adequate water intake also support better oral health.
How You Eat Matters as Much as What You Eat
“It’s not just what you eat but how you eat,” emphasizes Dr. Dheeraj Setia. Consuming sweets as part of a main meal rather than snacking throughout the day reduces the amount of time teeth are exposed to acids. Pairing sugary or acidic foods with water or fibrous fruits can also help lessen their impact.
Oral Hygiene: Your Strongest Defence
Daily brushing with fluoride toothpaste, consistent flossing and routine dental visits remain essential. “At The Dental Roots, we encourage patients to schedule regular checkups not just to prevent cavities, but to detect early signs of gum disease, misalignment or other oral concerns,” says Dr. Setia. With comprehensive dental solutions under one roof, from preventive care to advanced restorative treatments, maintaining a confident, healthy smile becomes easier.
A Healthier Smile Begins With Mindful Choices
As Dr. Dheeraj Setia reminds patients, “Your smile is one of your greatest assets, and protecting it starts with mindful food choices and regular professional care.” The next time you reach for a snack or drink, remember, what you eat shows up in your smile.
