If you’ve noticed white or chalky patches on your child’s teeth, you’re not alone. Many parents spot these marks when brushing or during routine check-ups and wonder whether it’s something to worry about. In many cases, this could be a condition called hypomineralisation – a developmental issue that affects how tooth enamel forms.
White or chalky spots on your child’s teeth could be a sign of hypomineralisation – a developmental condition where enamel doesn’t form properly. It can cause sensitivity, discolouration, and weak enamel. Early treatment from a specialist paediatric dentist like Dr Mali in Fulham helps protect your child’s teeth and prevent future decay.
At Dr Mali Dental Clinic in Fulham, our specialist paediatric team regularly helps children with hypomineralisation, protecting their teeth from sensitivity, decay, and long-term damage. In this guide, we’ll explain what causes chalky teeth, what you can do about it, and when it’s time to see a dentist.
Hypomineralisation is a condition where the enamel – the hard, protective outer layer of the tooth – doesn’t form properly during development. Instead of being strong and glossy, the enamel can appear soft, porous, or chalky.
The condition often affects the first permanent molars and incisors and is known as Molar-Incisor Hypomineralisation (MIH). Research suggests that around one in six children may experience some level of enamel hypomineralisation, making it a relatively common issue.
Healthy enamel acts as the tooth’s natural shield against wear, bacteria, and temperature changes. When enamel is weaker or incomplete, it leaves the tooth vulnerable to sensitivity, decay, and pain.
Put simply, hypomineralisation doesn’t mean the tooth is dirty or stained – it means the enamel didn’t develop correctly in the first place.
While researchers are still studying the exact causes, several factors are known to contribute to hypomineralisation in children’s teeth.
Some possible causes include:
It’s important to note that hypomineralisation is not caused by poor brushing or diet. Parents often blame themselves unnecessarily – but this is a developmental condition, not one caused by neglect or hygiene habits.
Hypomineralisation can vary in severity. In mild cases, it may appear as faint white or cream-coloured patches. In more severe cases, the teeth may appear yellow or brown and be prone to breaking or wearing down.
Look out for:
These symptoms are most often noticed on the front teeth and back molars when they first erupt.
If your child complains of tooth pain or sensitivity, or you notice changes in enamel colour or texture, it’s best to arrange a dental assessment.
The earlier hypomineralisation is detected, the easier it is to manage. Weaker enamel can make it harder for children to brush effectively, which increases the risk of decay.
Early diagnosis allows your dentist to:

Although hypomineralisation itself can’t be “cured,” good oral care can help protect affected teeth and prevent further complications.
Here are some steps parents can take:
Your dentist may also recommend professional fluoride applications or sealant treatments to provide extra protection against decay.
If you’ve spotted white, yellow, or chalky marks on your child’s teeth – or if they experience pain when brushing or eating – it’s important to have a specialist paediatric dentist assess them.
