External Resorption of a Tooth with Pink Appearance

External resorption is a slow and gradual process which results in decalcification and deterioration of tooth over time. It often appears as a pink area near the neck (cervical) aspect of a tooth in proximity of the resorption area. The pink area is the inflammatory tissue reflecting through the resorbed enamel and dentin. It is often due to history of trauma such as subluxation (partial loosening and dislocation) of complete luxation (total dislocation) and re-implantation. In such circumstances, tooth is treated endodontically (root canal) but certain percentage of such teeth develop external resorption. The only viable treatment with advanced resorption is extraction , site graft to preserve / augment the ridge and replacement with a dental implant.
