You have white spots or streaks on your teeth — your dentist called it fluorosis. It's a cosmetic condition caused by excess fluoride during childhood tooth development. Here's what it means for your teeth and what can be done.

Fluorosis happens when developing teeth are exposed to too much fluoride — usually between birth and age six, while the permanent teeth are still forming beneath the gums. The excess fluoride disrupts the normal enamel formation process, creating characteristic white patches or streaks on the surface of the teeth.

How much fluoride causes fluorosis?

The risk increases with higher fluoride exposure during those critical years. This can come from swallowing fluoride toothpaste, taking fluoride supplements when fluoride levels in your water supply are already adequate, or living in an area with very high natural fluoride in the water. Mild fluorosis is extremely common and often barely noticeable.

What does fluorosis look like?

Mild fluorosis appears as tiny white specks or chalky patches on the enamel. In moderate cases, the white areas are more extensive and may contain some brown staining. Severe fluorosis is rare and results in pronounced brown stains and rough, pitted enamel. Fluorosis does not affect tooth function — your teeth are still strong and healthy.

Does fluorosis increase cavity risk?

No. In fact, the fluorosed areas of enamel tend to be harder and more resistant to decay. The concern is purely cosmetic. Many people with mild fluorosis don't seek treatment at all, and it may even give teeth a unique, healthy appearance.

What can be done about fluorosis?

If you want to improve the appearance of fluorosis, options include teeth whitening (which can even out the colour contrast), microabrasion to gently remove surface staining, dental bonding for more noticeable patches, or veneers for a complete cosmetic transformation. Your dentist will recommend the best approach based on the severity of your fluorosis.

Preventing fluorosis in children

Supervise your child while they brush and use only a pea-sized amount of fluoride toothpaste. Teach them to spit it out rather than swallow. Keep fluoride supplements out of reach. With these simple precautions, your child's teeth develop normally and stay healthy.
