Which of the following succedaneous teeth are the first to erupt?

  1. Maxillary canines

  2. Mandibular incisors

  3. Maxillary molars

  4. Mandibular premolars

The correct answer is: Mandibular incisors

The first to erupt are typically the mandibular incisors. This is because of their smaller size and position in the mouth, making it easier for them to come through the gums. The maxillary canines, molars, and mandibular premolars usually come in later because they have larger roots and are more complex in shape, making it harder for them to erupt. While these teeth will eventually erupt, they typically do so after the mandibular incisors. Therefore, option B is the best answer.
