What "dental clearance" actually asks for

In short

A clearance request is not a request to make the mouth perfect. It is a request to remove anything that will become an infection or a non-healing wound at the one moment the patient cannot afford it. The answer is usually to clear active disease and treat emergencies definitively — but how much you clear turns on how much bone-healing capacity the coming treatment removes, not on how long a lesion has sat quietly: full clearance before high-dose head-and-neck radiation or ablative transplant conditioning, a narrower and more selective list before therapies that leave more healing capacity intact. The order matters: the irreversible treatments come first (head-and-neck radiation, intravenous antiresorptives, transplant), the cancer waits for nobody, so the plan is built backward from the start date and the surgery happens in the first week, not the last. Joint replacement is the outlier; routine clearance before arthroplasty has weak evidence behind it and is mostly a question of who is at risk, not whether everyone is. The letter back to the physician says what was found, what was done, what was deliberately left, and when the dentist wants the patient back.
