Fluoride strengthens enamel and helps repair the earliest stages of tooth decay. Used in the right amount, it's one of the simplest ways to protect teeth.
How much toothpaste?
- Under 3 years: a smear the size of a grain of rice
- 3 to 6 years: a pea-sized amount
- Older children and adults: a pea-sized amount is enough
Myth: more is better
Too much fluoride swallowed regularly in childhood can cause white marks on developing teeth. That's why small children need supervision while brushing and only a tiny amount of paste.
Myth: rinsing after brushing helps
Rinsing with water straight after brushing washes the fluoride away. Spit out the excess toothpaste, but don't rinse.
