Which tooth is immediately distal to the intermaxillary suture?

  1. Maxillary lateral incisors

  2. Maxillary canines

  3. Maxillary central incisors

  4. Mandibular central incisors

The correct answer is: Maxillary central incisors

The intermaxillary suture is the line of union between the two maxilla bones. Distal refers to the direction away from the midline of the body. This means that the tooth immediately distal to the intermaxillary suture would be the closest tooth on the maxilla bone that is furthest away from the midline of the body. The incorrect options are A Maxillary lateral incisors, B: Maxillary canines, and D: Mandibular central incisors. These teeth are all located on the maxilla and mandible bones, respectively, but they are not immediately distal to the intermaxillary suture. Instead, they are either too far away or located on different bones. Option C: Maxillary central incisors is the correct answer because they are the two front teeth on the maxilla bone and are located on either side of the midline
