Molar and Incisor Hypomineralization (MIH) is an enamel development defect of multifactorial origin that affects one-to-four permanent first molars and is frequently associated with permanent incisors. Clinically it is characterized by demarcated white-cream and/ or yellow-brown opacities. In severe cases, there may be tooth pain, posteruptive fractures, dental caries lesions, and/ or atypical restorations. Treatment options include temporary restorations with glass ionomer cement, restorations with composite resin, crowns, indirect restorations, and tooth extraction. When extractions are performed at the right time, it allows the spontaneous replacement of the second permanent molar, therefore, it is considered a viable and cost/effective treatment. The objective of this case report is to analyze the diagnostic considerations for the extraction of first permanent molars severely affected by MIH. Female patient, 9 years old, Class I skeletal pattern, Class I malocclusion, and severe MIH. For the treatment, it was decided to perform the extraction of the first four permanent molars under general anesthesia. After 10 months, it is observed that the second permanent molars are clinically healthy and have favorable inclinations and positions for spontaneous closure of the space. It is concluded that the extraction of first permanent molars severely affected by MIH is a strategy that improves the patient's prognosis and to carry out, it is necessary to work together with the orthodontist to diagnose and plan each case individually.
