Which tooth has the longest crown and second longest root overall?

  1. Mandibular canine

  2. Maxillary first premolar

  3. Mandibular first premolar

  4. Maxillary second premolar

The correct answer is: Mandibular canine

The correct answer is the Mandibular Canine. The mandibular canine has the longest crown and the second longest root overall among the options provided. Canines typically have a long, single, pointed cusp and a long root, which helps in providing stability and strength for functions such as cutting and tearing food. In this case, while the mandibular canine has the longest crown, the longest root goes to the maxillary canine, making the mandibular canine the correct choice for the given question.
