You look in the mirror and notice white patches or streaks on your teeth. They are not cavities — they are probably fluorosis.

Fluorosis is a condition that develops when teeth are exposed to too much fluoride while they are still forming under the gums. It affects the outer layer of the tooth — the enamel — and shows up as white spots, streaks, or in rare cases, brown stains.

It happens during childhood, typically between birth and about age 8, when permanent teeth are developing. Once the teeth break through the gums, you cannot develop fluorosis — the condition is already set.

Fluorosis occurs when young children swallow fluoride toothpaste, take fluoride supplements, or drink water with naturally high fluoride levels. The fluoride is incorporated into the developing enamel, changing its appearance.

Mild fluorosis is very common. In fact, millions of people have it and do not even realise until someone points it out.

Here is the good news: mild fluorosis is purely cosmetic. It does not weaken your teeth, cause pain, or lead to cavities. Your teeth are just as healthy — they just look a little different.

In severe cases, the enamel may become rough or pitted, which can trap stains. But this is rare and typically only happens with very high fluoride exposure.

If the white spots bother you, options exist. Teeth whitening can sometimes blend the white areas with the rest of the tooth. Microabrasion removes a thin layer of discoloured enamel. Composite bonding or veneers cover the teeth entirely for a uniform appearance.

Your dentist will recommend the best approach based on how severe your fluorosis is.

Supervise your child when they brush. Use only a smear of fluoride toothpaste for babies and a pea-sized amount for toddlers. Encourage them to spit, not swallow. Check your water supply if you use a well — natural fluoride levels vary.
