How to Prevent Cavities in Children: Parent's Dental Guide in Oakville

Tooth decay is the most common chronic childhood condition, but the great news is that it is almost 100% preventable! Protecting baby teeth (primary teeth) is essential because they guide permanent adult teeth into proper alignment.

1. Dental Sealants: Shielding Deep Molar Grooves

Molar teeth have microscopic cracks where food sticks. Dental sealants coat these chewing surfaces with a protective resin shield, reducing molar decay by up to 80%.

2. Professional Fluoride Varnish Applications

Applied in 1 minute during routine checkups, concentrated fluoride varnish strengthens enamel against acid attacks and reverses micro-cavities before they grow.

3. Healthy Snacking & Avoiding Hidden Sugars

Sticky snacks like fruit gummies, dried fruit, and juice boxes cling to teeth for hours. Encourage cheese, fresh fruits, veggies, and water as teeth-friendly alternatives.

4. Making Brushing Fun for Toddlers

Use a 2-minute timer app, musical toothbrushes, and let kids choose their favorite character toothpaste. Parents should assist with brushing until age 7–8.
