After extracting all teeth, which teeth should be left in place for immediate dentures?

In the context of preparing for immediate dentures after tooth extractions, it is crucial to consider the role of teeth in maintaining occlusion and esthetics. The option of leaving teeth #12 and #21 in place is typically recommended because these teeth are often located in the anterior section of the arch (maxillary and mandibular premolars). Preserving these specific teeth not only provides improved esthetic outcomes by maintaining some natural tooth structure, but they also assist in achieving a more stable occlusion for the immediate dentures being placed.

Teeth #8 and #9 refer to the maxillary incisors, which are often the focal point of a person's smile. However, these might be extracted if more extensive work is needed, but they are generally not the ideal candidates for retention during the immediate denture process unless specific considerations like their condition are evaluated. Similarly, teeth #4 and #5 (typically first and second premolars in the mandible) and teeth #18 and #19 (the lower third molars) are often not prioritized for retention as they do not significantly contribute to immediate support or esthetics in transitional dentures.

Retaining the appropriate teeth is essential not only for functional reasons but also for patient comfort and satisfaction during the transition to full
