What does MIH mean in PHYSIOLOGY

MIH is an oral health condition which causes permanent molars and incisors to be hypomineralised, meaning they are soft and prone to damage due to enamel defects. The condition is often identified by discolouration - which may appear as white or yellow spots on the teeth - as well as sensitivity and enamel loss.

While anyone can get MIH, it seems to be most common among school age children and teenagers aged 6-14 years old. Research also suggests that genetics may play a role in the development of MIH, but further studies are needed to confirm this.

A dentist will usually diagnose MIH by looking for signs such as discolouration, grooves or pits in the tooth's surface, enamel loss or sensitivity. X-rays may also be taken so a more accurate picture of any underlying structure damage can be obtained.

Treatments for MIH typically involve restoring affected teeth with fillings or crowns if there is enough healthy enamel left; however, if the entire crown of a tooth has been affected then extraction might be recommended instead. Additionally, topical fluoride treatments can help reduce further erosion due to acid exposure from food or drinks.

Prevention of new lesions is best achieved via good oral hygiene practices such as brushing twice daily using fluoride toothpaste, regular flossing and limiting sugary foods and drinks throughout the day. If your child already has lesions you should encourage them not to pick at their teeth or use hard bristled brushes when brushing; additionally regular visits to the dentist are important for monitoring any changes over time.
