Introduction: All the teeth undergoing pulp space therapies require a good form of post-endodontic restoration to rehabilitate the teeth back to functionality. Root canal treatment is a procedure which removes the part of tooth structure during access and canal shaping, removes vital contents of the pulp space, which in due course leads to increased fragility of the remaining tooth structure due to dehydration and loss of elasticity of dentin. There is increased prevalence rates of tooth fractures in endodontically treated teeth due to diminishedfunctional architecture. Full coverage restorations further weakens the tooth. Preservation of maximum tooth structure with conservative tooth preparation contemplates as the standard measure for restoring teeth. Case Description: Recently, endocrowns have been introduced as conservative modality of treatment as post-endodontic restoration. This case report delineates the treatment aspect of endodontically treated left mandibular 2nd molar with metal endocrown. Clinical significance: Treatment of severely mutilated teeth with conservative mode of treatment plays a great role of clinician’s assertiveness and capacity to rebuild the lost tooth structure with minimal approach. Minimal invasive dentistry is the new norm and preservation of remaining tooth structure is the key to success.
