7 Cavity-Prevention Strategies

  • Brush twice daily with fluoride toothpaste β€” Use a rice-grain amount for under 3, pea-sized for 3+.
  • Floss daily once teeth touch β€” Start this habit early and it becomes automatic.
  • Limit sugary snacks and drinks β€” Frequency matters more than quantity. Avoid constant snacking.
  • Choose water over juice β€” Water is the best drink for teeth. If juice, dilute it and limit to meals.
  • Visit the dentist every 6 months β€” Professional cleanings and fluoride treatments provide extra protection.
  • Consider dental sealants β€” These protective coatings on molars reduce cavity risk by 80%.
  • Lead by example β€” Let your kids see YOU brushing and flossing. They learn from watching you.
πŸ’‘Pro Tip

Make brushing fun! Use a timer app, play a 2-minute song, or let kids pick their own toothbrush. When brushing is enjoyable, kids are more likely to do it well.
