Managing a Child With a Bleeding Disorder Before Extraction
A 9-year-old boy is referred for extraction of a severely carious primary mandibular second molar that is causing intermittent discomfort. His mother reports he has von Willebrand disease, diagnosed at age 5 after prolonged bleeding following a tonsillectomy. He is not currently on any prophylactic medication. He has no known allergies. His pediatric hematologist is reachable by phone. The tooth is restorable only with difficulty, and the family prefers extraction. The clinic has no on-site hematology support.
1. What is your preoperative assessment and coordination plan before extracting this tooth?

The key issue is bleeding risk, not the extraction itself. Before scheduling, contact the hematologist to confirm the subtype and severity of von Willebrand disease, his baseline factor levels, his bleeding history (the post-tonsillectomy bleed is a significant red flag), and the recommended perioperative regimen. Depending on subtype and severity, the hematologist may recommend desmopressin or a von Willebrand factor concentrate before the procedure, and may advise on antifibrinolytics such as tranexamic acid.
Do not proceed without that input. The extraction should be scheduled when hematology support is available, ideally with the hematologist's written recommendations in hand. Local hemostatic measures (sutures, hemostatic agents, pressure) should be planned, and the family should be given clear post-operative bleeding instructions and a direct contact pathway.
2. The family asks whether the tooth can just be 'watched' to avoid the bleeding risk. How do you weigh the risks, and what would change your recommendation?

Watching a symptomatic, severely carious tooth risks progression to pain, infection, and possibly space loss, and infection in a child with a bleeding disorder is itself a management problem. The bleeding risk is real but manageable with hematology coordination, so the balance generally favors definitive treatment rather than indefinite observation.
What would change the recommendation: if the hematologist advised that the child's bleeding risk could not be safely managed in an outpatient setting, or if the child had a severe subtype requiring inpatient management, then the setting would change (hospital-based care) rather than the decision to treat. If the tooth were asymptomatic and restorable, a restorative approach might be preferred to avoid extraction altogether. The judgment is to treat the disease while managing the systemic risk, not to let the systemic diagnosis drive avoidance of needed care.
