Does getting dentures require tooth extraction?

Introduction
Whether a patient needs tooth extraction prior to dental prosthesis depends on the specific clinical situation. If the tooth is a residual crown or residual root with no restorative value, extraction is necessary before prosthetic treatment. However, if the tooth itself is in good condition and has undergone root canal treatment—yet still requires a prosthesis—extraction is not needed; the root canal–treated tooth can be retained for restoration.
Dental prosthetics (i.e., “tooth replacement”) primarily addresses tooth defects, partial edentulism (loss of some teeth), or complete edentulism (total loss of teeth). It includes removable dentures, fixed prostheses, dental implants, and complete dentures. Removable dentures can be inserted and removed by the patient independently. Fixed prostheses are further categorized into metal-ceramic, all-ceramic, and resin-based types, and require adjacent natural teeth on either side of the missing tooth as abutments for support and stabilization. So, does tooth replacement always require tooth extraction? Below, we address this question.
Is Tooth Extraction Necessary for Dental Prosthetics?
Whether tooth extraction is required prior to dental prosthetics depends entirely on the individual clinical situation. If a patient presents with a severely damaged crown or root remnant lacking restorative potential, extraction is necessary before prosthetic treatment can proceed. Conversely, if the natural tooth is otherwise healthy—even following root canal treatment—extraction is not indicated; the treated tooth can serve as a foundation for prosthetic restoration.
In such cases, the tooth is prepared (i.e., shaped), an impression is taken, and the prosthesis is fabricated and placed directly over the existing tooth. However, when fabricating removable dentures, extraction may be required for severely tilted or excessively mobile abutment teeth to ensure proper fit, function, and long-term stability of the prosthesis.
Additionally, several important considerations must be noted: Dental prosthetics are generally not recommended for young patients whose permanent teeth have not yet fully developed; alternative temporary restorative options may be more appropriate. If other less invasive or more suitable restorative approaches adequately meet the patient’s functional and aesthetic needs, dental prosthetics should be avoided. Furthermore, prosthetic treatment is contraindicated in cases of uncontrolled severe periodontal disease or untreated apical pathology until these conditions are properly managed and stabilized.
