A periapical radiograph reveals a mesiodens in a 7-year old. The maxillary right central incisor has erupted only partially. The maxillary left central incisor has not yet appeared. The proper threatment in this situation is to

remove the mesiodens, band the unerupted central incisor and institute orthodontic therapy

remove the mesiodens and observe progress carefully

allow the mesiodens to erupt before attempting extraction

allow the mesiodens and the right central incisor to erupt into the oral cavity to determine their relative positions
