Preventing cavities requires 3 daily habits: brushing twice daily with fluoridated toothpaste (1000–1450 ppm) for two full minutes, cleaning between teeth daily with floss, and reducing between-meal snacking on refined sugars and sticky sweets. In-clinic pit and fissure sealants (₹600–₹1,200) provide 80% protection for children’s molars.

1. The Science of Tooth Decay: The Stephan Curve
Cavities are not caused by worms! When you consume carbohydrates or sugars, oral bacteria (primarily Streptococcus mutans) ferment them and produce acid within 5 minutes. This drops mouth pH below the critical threshold of 5.5, dissolving enamel minerals (demineralisation). It takes 30 to 45 minutes for saliva to neutralise the acid. Frequent snacking on biscuits, chai with sugar, or sweets subjects your teeth to constant acid baths throughout the day.
2. The Golden ‘Spit, Don’t Rinse’ Brushing Rule
Most Indian families brush their teeth and immediately rinse their mouth multiple times with water. Stop doing this! Rinsing washes away the concentrated fluoride layer before it can incorporate into your enamel crystals to form acid-resistant fluorapatite. After brushing, spit out excess toothpaste foam, but do not rinse with water for at least 20 minutes.

Frequently Asked Questions (FAQs)
Can an early cavity heal naturally?
Yes! When decay is confined to the outer enamel (incipient white spot), prescription fluoride toothpastes and CPP-ACP remineralising creams can reverse it without drilling.
Is jaggery (gud) safer for teeth than white sugar?
No. From a dental perspective, bacteria ferment jaggery, honey, and raw sugar into the exact same destructive enamel-dissolving acids.
