Fluoride & Dental Decay

Why Fluoride is Essential for Preventing Tooth Decay

Fluoride is a naturally occurring mineral that plays a vital role in strengthening tooth enamel and preventing cavities. In Christchurch, where families value quality care and long-lasting dental health, fluoride treatments are an effective way to protect teeth from the daily challenges of modern diets and busy lifestyles.

Our advice follows the latest guidance from the Department of Health, which highlights the importance of twice-daily brushing with fluoride toothpaste. Regular fluoride application helps to remineralise enamel, making teeth more resistant to decay—especially for those at higher risk of developing cavities.

Fluoride Advice for Adults

We recommend that all adults brush their teeth at least twice daily with a fluoride toothpaste containing between 1,350 to 1,500ppm fluoride. It is important to brush for two minutes, particularly before bed, and to spit rather than rinse after brushing to ensure the fluoride remains on the teeth for longer.

For adults who experience higher-than-expected decay rates, we can prescribe high-fluoride toothpaste (2,800ppm or 5,000ppm) to provide additional protection. We may also suggest incorporating a fluoride mouthwash into your routine at a different time to brushing, such as after lunch, to further safeguard your teeth against decay.

Fluoride Advice for Children

Good oral hygiene habits should start from an early age, and fluoride plays a key role in protecting children’s developing teeth. Our family-friendly practice in Christchurch encourages parents to supervise their children’s brushing and follow the following guidelines:

• Children under 3: Use a smear of fluoride toothpaste (at least 1,000ppm fluoride) twice daily.

• Children aged 3-6: Brush twice daily with a pea-sized amount of fluoride toothpaste (at least 1,000ppm fluoride).

• Children aged 7 and above: Brush twice daily with fluoride toothpaste containing 1,350-1,500ppm fluoride.

For children at higher risk of cavities, we offer professional fluoride varnish applications during routine check-ups to provide extra protection in vulnerable areas.
