What fluoride actually does

Fluoride is a naturally occurring mineral found in water, foods and dental products. It protects your teeth by:

• strengthening enamel
• making teeth more resistant to acid attacks
• slowing demineralisation
• helping reverse early decay

‍

Fluoride reduces cavity risk by around 25% according to clinical evidence .

‍

How fluoride protects your teeth

1. Remineralises enamel

Fluoride helps redeposit minerals like calcium and phosphate back into weakened enamel, repairing early damage.

2. Makes enamel more acid‑resistant

It hardens the outer layer of your teeth, making them less vulnerable to plaque acids.

3. Slows bacterial activity

Fluoride disrupts acid‑producing bacteria that cause cavities.

4. Helps both children and adults

Children benefit during tooth development, but adults also benefit from topical fluoride in toothpaste, mouthwash and varnish.

‍

Types of fluoride you may use

Fluoride toothpaste

Most toothpastes contain 1000–1500 ppm fluoride, which is proven to prevent decay.

Fluoride mouthwash

Useful for people at higher risk of cavities.

Fluoride varnish

Applied by dentists to strengthen enamel and reduce decay risk.

Fluoridated water

Helps reduce tooth decay at a community level.

Benefits of fluoride

Fluoride Myths vs Facts

Myth 1: Fluoride is unsafe

Fact: Fluoride is safe at recommended levels and is one of the most effective ways to prevent cavities.

Myth 2: Fluoride is only for children

Fact: Adults benefit from fluoride just as much — especially those with dry mouth, gum disease or a history of decay.

Myth 3: Natural toothpaste without fluoride is better

Fact: Toothpaste without fluoride does not protect against cavities. Many “natural” toothpastes contain no fluoride at all.

Myth 4: Fluoride causes major health problems

Fact: Reviews show no convincing evidence linking fluoride at normal levels to serious health issues.

Cons and risks of fluoride

1. Dental fluorosis (mostly cosmetic)

Occurs when children ingest too much fluoride while teeth are developing.Usually appears as faint white streaks and is not harmful.

2. Overexposure from natural water sources

Some regions worldwide have naturally high fluoride levels, which can cause fluorosis or skeletal issues.

3. Excessive use of supplements

Fluoride tablets should only be used when prescribed.

4. Silver diamine fluoride aesthetic drawback

Highly effective at stopping decay but can darken the treated area.

How to use fluoride safely

Brush twice daily with fluoride toothpaste

Use 1000–1500 ppm fluoride toothpaste for best protection.

Don’t rinse after brushing

Rinsing washes fluoride away.

Supervise children’s brushing

Use a smear for under‑3s and a pea‑sized amount for ages 3–6.

Use fluoride mouthwash at a different time to brushing

Prevents washing away toothpaste fluoride.
