Dental, heart and infection clearance before a transplant | CION Cancer Clinics

Because a hidden tooth or gum infection can turn dangerous once your white cell count drops after the high-dose treatment. Dental clearance means a dentist has checked your mouth, treated anything that could flare up, and written that you are fit to go ahead.

What happens to the mouth during a transplant

The conditioning treatment lowers your immunity for weeks. It also makes the lining of the mouth sore and broken. Germs from a decayed tooth, a gum pocket or an old root can then enter the blood. An infection that was silent for years can become a fever that needs intensive care.

Why it has to happen early

If a tooth needs to come out, the socket needs time to heal before admission. If dental work is left to the last week, the transplant date often moves. That is why most centres ask for the dental visit near the start of the workup.

Who this matters most for

Everyone having a transplant needs the check. It matters most for people with old fillings, loose or broken teeth, bleeding gums, wisdom teeth that trouble them, or dentures that rub.

Who it does not suit to rush

If your counts are very low from recent chemotherapy, a big dental procedure may have to wait for them to recover, or be planned with transfusion support. The dentist should not decide this alone. Ask them to speak with your haematologist first, and to put the plan in writing so the transplant centre can see it.

Dental clearance is one of three. The centre also wants to know that your heart can cope with the treatment and that no infection is waiting to flare up.

Heart clearance

Some chemotherapy medicines used earlier can weaken the heart. An ECG checks the rhythm and an echocardiogram shows how strongly the heart pumps. If you have diabetes, blood pressure or a past heart problem, a cardiologist may review you and write their own note. A weaker result does not always rule a transplant out. It may change which conditioning treatment is chosen.

Infection clearance

Blood tests look for HIV, hepatitis B and C, CMV and other viruses. A chest X-ray or CT looks for lung infection, and many centres check for past TB. Sinus, skin, urine and piles problems are also asked about. A positive result usually means a preventive medicine during the transplant, not a cancelled one.

Who signs off

Each specialist writes a note. The transplant physician reads them all together and makes the final call. If two notes seem to point in different directions, ask the transplant physician to explain how they weighed them, and what would need to change for you to go ahead.

Clearance is delayed most often by teeth that need removing late, by a new infection found on a scan, or by a heart result that needs a specialist opinion. Each adds time, and the team will explain how much.

What the page cannot tell you

It cannot tell you whether your own results are good enough. Each centre sets its own standard, and it depends on the type of transplant and your disease. A clearance list from one centre may not match another.

How CION helps

CION's haematology team can review your reports, explain what each clearance is looking for and help you plan the dental and heart visits early. CION does not perform transplants. It presents your case at a tumour board and coordinates with qualified transplant centres, and it tells you which questions to ask there.

For the family member arranging visits

Keep one folder for every clearance: the dental letter and X-ray, the ECG and echocardiogram reports, the infection test results and any specialist notes. Write the date on each. When the centre asks for something again, you will have it in hand, and a missing paper will not be the reason the admission date slips.
