Hypomineralization occurs when an imbalance occurs during the maturation phase. It manifests as a change in tissue translucency. A white or yellowish/brownish area is visible, with no change in thickness. The condition affects the first permanent molars (FPM) and has been discovered that these defects can affect both primary and permanent teeth. The etiology has been seen to be multifactorial and explored in detail in the research. Molar Incisor Hypomineralization (MIH) can have a wide range of severity. It can range from minor opacities to complete post-eruption. Asymmetrical presence is its characteristic feature. MIH is a problem that needs a long-term solution. Thus, the treatments provided in children are for decades and require a long-term perspective. Management of affected molars and incisors has been dealt with intensively in the book. A nationwide awareness and prevention program may help in the management and prognosis of the condition.
