Compromised Teeth Preserve or Extract: A Review of the Literature

Multiple systems and associated factors have been described in the literature to assess the prognosis of teeth with periodontal disease. Nowadays there is a tendency among clinicians to consider implants as the best solution after tooth extraction, in cases of teeth with a questionable prognosis. However, the value of the natural tooth must be considered, as the proprioception of the periodontal ligament is preserved, and it adapts to stress during functional loads. We first review the literature focusing on analyzing the factors that should guide decision-making to maintain or extract a tooth with a compromised periodontium. Then, we propose a schematic diagram of prognostic indicators to reflect the main factors to consider and the survival rate that each one represents when preserving or extracting a tooth.

Multiple systems and factors have been described in the literature for assessing the prognosis of teeth with periodontal disease. Clinicians tend to favor implants as the best solution after tooth extraction, but the value of preserving natural teeth should also be considered as they provide proprioception and adapt to functional loads.
