Dental cavities (also called dental caries) are the single most common chronic childhood disease worldwide. In India, studies show that over 50% of children under the age of 5 have at least one cavity. But here's the important part: cavities are largely preventable.
How do cavities form?
Cavities develop when bacteria in the mouth feed on sugars from food and drinks, producing acid that attacks tooth enamel. Over time, this acid erosion creates holes in the teeth — what we call cavities.
Three factors need to be present simultaneously for a cavity to form: bacteria, sugar, and time. Remove or reduce any one of these and you significantly lower the risk.
Brushing: the foundation of prevention
- Start cleaning your baby's gums with a soft, damp cloth even before teeth appear
- Use a rice-grain-sized amount of fluoride toothpaste for children under 3
- Use a pea-sized amount for children aged 3 to 6
- Brush twice daily — morning and before bed. The bedtime brush is the most important
- Parents should brush for children until age 6, and supervise until age 8–9
- Replace toothbrushes every 3 months or when bristles splay
Diet: what matters more than you think
It's not just how much sugar a child consumes — it's how often. Frequent snacking on sugary foods creates repeated acid attacks on the teeth. Here are practical dietary tips:
- Limit juice, flavoured milk and sugary drinks — water is always the best choice
- Avoid putting a child to bed with a bottle of milk or juice (this causes "bottle caries")
- Offer sweets with meals rather than as standalone snacks
- Choose cheese, nuts, fruits and vegetables as between-meal snacks
- Sticky foods like toffee, dried fruit and biscuits cling to teeth longer and are more harmful
The role of fluoride
Fluoride strengthens tooth enamel and makes it more resistant to acid attacks. Using a fluoride toothpaste, drinking fluoridated water (where available), and professional fluoride applications during dental visits are all effective ways to protect your child's teeth.
Professional prevention: sealants and check-ups
Dental sealants are thin, protective coatings applied to the chewing surfaces of back teeth. They fill in the natural grooves where food and bacteria tend to collect. Sealants can reduce cavity risk by up to 80% in these areas.
Regular dental check-ups (every 6 months) allow the dentist to catch early signs of decay before they become painful cavities. At Care & Cure, we focus on prevention first — because the best filling is no filling at all.
