People treated with head-and-neck radiotherapy should disclose that history to their dentist before extraction or implant placement and review the planned site’s radiation dose with the oncology team. Irradiated jawbone may have reduced blood supply and wound healing, creating a risk of osteonecrosis, while salivary-gland damage can increase dry mouth, decay, and gum disease. Waiting periods mentioned in the article are not universal guarantees of safety. Treatment location, dose, elapsed time, and current bone condition should jointly guide the procedure and its timing.
