We speak with Dr. Ryan Lee of Memorial Sloan-Kettering Cancer Center about dental care before, during, and after a bone marrow or stem cell transplant. Dr. Lee is a chief dental officer, lieutenant colonel, oral oncologist, and implantologist. He explains why dental planning must consider more than the immediate transplant period. As treatments improve, many survivors are living for decades. Their teeth and gums need to support them throughout long term survivorship.
Patients undergoing transplant may face weakened immunity, infection, bleeding, mouth sores, dry mouth, pain, taste changes, and difficulty chewing or swallowing. These problems can occur together and make each other worse. A mild dental issue can become a serious infection when blood counts are low. Poor oral health can also interfere with eating and maintaining proper nutrition.
Dental clearance should identify teeth that must be treated before transplant and problems that can safely wait. Dr. Lee stresses that this decision is different for every patient. Dentists need to understand the type of transplant, the likelihood of Graft Versus Host Disease, current medications, and the expected long term condition of each tooth. Communication between the dental team and the hematology and oncology team is essential.
A strong daily oral care routine should begin before treatment. Patients should use a medium or soft toothbrush, clean between the teeth, and consider a water flosser when regular flossing causes bleeding. Dentures, partials, crowns, bridges, and implants require careful cleaning because they can collect bacteria and fungus. Patients should also know where these restorations are located so future dental providers can give specific instructions. Saliva acidity and dry mouth should also be discussed because they can greatly increase cavity risk.
During treatment, mucositis may cause painful sores throughout the mouth. Frequent water intake, nutritional drinks, and prescribed mouth rinses may make eating more manageable. Some rinses contain antimicrobial medication and lidocaine to reduce infection risk and temporarily numb the mouth.
Dental procedures must be planned around blood counts and medication schedules. Invasive work may be safest shortly before the next chemotherapy or immunosuppressive treatment, when blood counts have had the most time to recover. During neutropenia, elective treatment may need to stop while the dentist focuses on controlling pain and infection. During thrombocytopenia, extractions or other procedures may need to wait because bleeding may be difficult to control.
Dr. Lee recommends creating a dental timeline that separates urgent pretransplant treatment from work that can wait six, twelve, eighteen, or twenty four months. Long term survivors should build a consistent relationship with dentists and hygienists who understand their medical history. Pediatric survivors require additional support because treatment can affect developing adult teeth, tooth roots, spacing, appearance, and self confidence.
The central message is that dental care is part of transplant care. Early planning, daily prevention, current blood count information, and communication between providers can protect comfort, nutrition, and quality of life for many years.
