What is MIH and what caused my child to have it?
MIH is a common condition affecting one in eight children in the UK. In teeth affected by MIH, the outer layer (enamel) of the tooth doesn’t form properly. This means it can be sensitive, crumbly and more prone to tooth decay. Teeth may appear “chalky” or discoloured with a cream, yellow or brown appearance.
It most commonly affects one, some or all four of the back first adult molar teeth, which come through around the age of six years. It can also affect the front teeth. Teeth are not necessarily equally affected, and the front teeth usually do not have the same loss of enamel as the molars. Other adult teeth are unlikely to be affected.
The cause of MIH is not fully understood. It is thought to be caused by a disturbance whilst these teeth are developing. This happens around the time of birth or within the first few years of life. Childhood illness, high fever or difficult births are some of the things that may cause these disturbances.
What can I do at home?
Brushing regularly with fluoride toothpaste, restricting sugar in your child’s diet and regularly attending your dentist are especially important if your child has MIH. Applying tooth mousse First adult molar (back) tooth affected by MIH (which can be purchased online) to affected teeth at home can help with sensitivity (this cannot be used if your child has a cow’s milk allergy)
Treatment
Treatment options will depend on several factors and your dentist will discuss these with you to find the best option for your child.
Back teeth
Treatment will depend on how sensitive or broken down the teeth are, the current age of your child, whether the teeth are likely to last into adulthood and whether there are any missing teeth.
Your dentist may advice simple temporary fillings (which don’t involve any numbing) to try and keep the tooth until your child is a little bit older before making a permanent decision.
Some permanent treatment options include:
- plastic coatings
- white fillings
- tooth removal
- If the tooth is of poor quality, it may be beneficial to remove the tooth, which if done at the right age gives the adult teeth behind the best chance to close the gap.
- If taking out an affected bottom back tooth, in some cases it might be advisable to remove the opposing top back tooth, even if it is healthy, to prevent future issues with your child’s bite.
Front teeth
Treatment options for front teeth in children include:
- special polishing technique to help improve the appearance
- white fillings – covering the affected area or in some cases the whole tooth
- tooth whitening – currently can only be done when over the age of 18
