Hematologists are urging adoption of routine dental preventive care and oral health assessment as part of the CAR-T therapy pathway. The argument centers on infection-risk mitigation during the period of immune suppression, where oral inflammation can become a clinical hazard. The push reframes CAR-T support care as a multidisciplinary process that includes dentists, not just oncology teams. The proposal highlights preventive screening and ongoing oral assessments as a standard component of CAR-T patient management. While the content is advocacy-led rather than a trial result, it targets a practical gap frequently faced in CAR-T centers: preventing avoidable infectious complications that can derail response timelines and overall outcomes.
