Which is the largest premolar?

  1. Maxillary first premolar

  2. Maxillary second premolar

  3. Mandibular first premolar

  4. Mandibular second premolar

The correct answer is: Maxillary first premolar

The largest premolar is the maxillary first premolar because it is located in the anterior of the mouth and has multiple cusps, allowing for better chewing and grinding of food. The maxillary second premolar is not as large because it is located more posterior in the mouth and has fewer cusps. The mandibular first and second premolars are also smaller in comparison, with the mandibular first premolar being slightly larger than the second premolar due to its location in the anterior of the mouth.
