Find out which snacks may harm your dental health, from your favourite Indian treats to energy bars.

Are you frequently in the habit of snacking? Turns out your dental health may be in danger, even if you brush twice a day religiously. All-day nibbling can invite several problems, which is why you need to be mindful and resist the temptation to binge eat. To understand why it's important to keep your snacking habits in check, HT Lifestyle reached out to Dr Nikita Motwani, who specialises in aesthetic dentistry, co-founder at Smile Concepts Multi-speciality Dental Clinic.

She revealed that even when you brush twice a day, you still can't undo the damage caused by constant snacking. Dr Motwani shared her personal observation based on her clinical practice:" As a general dentist, I see this constantly with many of my patients who practice proper brushing but still have cavities due to the timing and contents of their snacking.

Why snacking may harm your dental health?

The dentist further explained how snacking exerts strain on your dental health.
Whenever you consume food or drink that is high in sugar or starch, your oral bacteria convert both of these into acids. This acid has a corrosive effect on enamel, lowers the pH of what is considered normal for the mouth, and this causes acid attack, which lasts for twenty to thirty minutes after you eat or drink something," she elaborated.

Moreover, Dr Motwani revealed that many people follow a grazing lifestyle where they snack persistently on biscuits, dry fruits, coffee and evening treats. The results are alarming as the teeth never get a break. Because of this constant snacking, the mouth stays acidic for hours, preventing saliva from repairing enamel and substantially raising the risk of cavities. She instead recommended scheduled eating to give your teeth longer recovery periods.

Snacks that are not teeth-friendly

Indian snacks get stuck in between teeth, making it an ideal environment for cavities to grow.

The dentist warned about these snacks, which may trigger dental-related issues if you are not careful with the portion:

  • Sticky dry fruits: Raisins, dates, figs, anjeer rolls, and energy bars stick between teeth and stay there for hours.
  • Indian namkeen and chips: Carbs break down into sugar, and fine crumbs get lodged in grooves.
  • Granola/energy bars: Most granola/energy bars we eat contain unwanted sugars. Most bars have a lot of honey or syrup.
  • Fruit juice/smoothie/coconut water: Very high in sugar and acid from fruit, without even adding sugar on top of that.
  • Masala chai/cold coffee: If you're drinking masala chai or coffee every day with many sugars, it's a cavalcade of acid. Drinking one cup of coffee for an hour results in 4 to 5 separate acid attacks.

ABOUT THE AUTHOR
Adrija Dey

Adrija Dey’s proclivity for observation fuels her storytelling instinct. As a lifestyle journalist, she crafts compelling, relatable narratives across diverse touchpoints of the human experience, including wellness, mental health, relationships, interior design, home decor, food, travel, and fashion that gently nudge readers toward living a little better. For her, stories exist in flesh and bones, carried by human vessels and shaped through everyday endeavours. It is the small stories we live and share that make us human. After all, humans and their lores are the most natural and raw repositories of stories, and uncovering them, for her, is akin to peeling an orange under a winter afternoon sun. Always up for a chat, she believes the best stories come from unfiltered yapping, where "too much information" is kind of the point. A graduate of Indraprastha College for Women, University of Delhi, and an alumna of the Indian Institute of Mass Communication (IIMC), Delhi, Adrija spends her idle hours cocooned with herbal tea and a gripping thriller, scribbling inner monologues she loosely calls poetic pieces, often with her succulents in attendance. On lazier days, she can be found binge-watching, for the nth time, one from her comfort-show holy trinity: The Office (US), Brooklyn Nine-Nine, or Modern Family. Dancing by herself to her peppy playlists, however, is an everyday ritual she swears by religiously.
