Dental Care After Stem Cell or Bone Marrow Transplant

Oral Issues Common in Transplant Survivors

Several oral conditions are unusually common in this population:

Chronic oral graft-versus-host disease. Allogeneic transplant survivors may develop chronic oral GVHD, with symptoms ranging from oral discomfort and lichen planus-like lesions to severe dryness, sensitivity, and difficulty eating. Long-term management is critical.

Severe and persistent xerostomia. Many transplant survivors experience long-term dry mouth, often from a combination of conditioning regimens, total body irradiation, and chronic GVHD effects on salivary glands.

Increased decay and gum disease risk. Reduced saliva, immune suppression history, and altered oral microbiology accelerate dental breakdown.

Tooth developmental abnormalities. Pediatric transplant survivors may have abnormal tooth development, missing teeth, undersized teeth, or root abnormalities.

Mucosal changes. Atrophic, sensitive, or fibrotic oral tissues that may persist long after immunological recovery.

Increased oral cancer risk. Allogeneic transplant survivors face elevated lifetime risk of oral squamous cell carcinoma, particularly those with chronic oral GVHD. Regular oral cancer screening is essential.

Bone modification effects. Some transplant patients receive bisphosphonates or other bone-modifying drugs, which require attention in any future dental planning. See osteonecrosis.

What Specialized Care Looks Like

For transplant survivors, dental care includes:

Coordinated planning with hematology. We typically communicate with your hematologist or transplant team before any significant procedure, particularly when immunosuppression is ongoing.

Frequent surveillance. Most transplant survivors benefit from dental cleanings and exams every 3 months, with detailed oral cancer screening at each visit.

Active management of dry mouth and tissue health. Saliva substitutes, prescription stimulants, custom fluoride trays, and topical treatments for chronic oral GVHD when present.

Restoration of damaged teeth. Crowns, bridges, and veneers for survivors whose teeth have been affected by long-term decay or GVHD.

Cautious approach to extractions and surgery. Coordination with the transplant team about timing, antibiotic prophylaxis, and bleeding precautions. For patients on long-term immunosuppression, additional precautions are usually warranted.

Dental implants where appropriate. Many transplant survivors are good implant candidates, particularly those with stable engraftment, adequate bone, and well-controlled GVHD.

When to Begin Care

After successful transplant, dental care should resume once your transplant team agrees you are stable enough for elective dental work. For most patients, this is several months to a year post-transplant. Earlier intervention may be needed for active dental problems.

For survivors who are years out from transplant, it is never too late to establish specialized dental care. Many of the issues we address, chronic GVHD, dry mouth, accumulated decay, develop over time and benefit from focused management at any stage.

Working With Your Transplant Team

We coordinate with hematology and transplant teams routinely. Common areas of communication include:

• Timing of elective procedures around immunosuppression and graft monitoring
• Antibiotic prophylaxis recommendations
• Bleeding precautions for thrombocytopenic patients
• Documentation of oral changes that may relate to GVHD activity
• Safe management of patients on bisphosphonates or denosumab
