If a small implant part or dental instrument has disappeared into your mouth, seek urgent medical advice about the missing object. Do not assume that it was swallowed because you can breathe normally. If you have difficulty breathing or severe symptoms, contact your local emergency service immediately.
A loose part that you have found and kept is a different situation from an object that cannot be accounted for. Tell the dental or medical team which situation applies. Repairs to the restoration can be planned after the concern about the missing object has been addressed.
Swallowing and inhalation lead to different places
A swallowed object enters the digestive tract. An inhaled object enters the airway. The Guy's and St Thomas' NHS patient guidance explains that assessment may involve imaging to identify an object and its position. The need for removal depends on what it is and where it has gone.
The NHS guidance also explains that an object identified in the airway needs removal by the medical team. Swallowed objects have a different assessment pathway. These distinctions are why a missing screw should not be treated as an ordinary lost crown filling.
If you are referred to hospital after the event, follow the team's instructions about food and drink. The NHS leaflet advises avoiding them until discharge because a procedure to retrieve the object may be needed. Do not use food to try to push an unknown object onward.
A few coughs did not identify the route
In a 2022 report by Wu and colleagues, an implant screwdriver slipped into a patient's mouth during treatment. The patient had little discomfort beyond a few coughs. The initial assumption was that it had been swallowed, but imaging identified it in the lung and it was removed through the respiratory service.
The case concerns a clinical instrument, not the likelihood of swallowing a particular implant screw at home. Its relevant lesson is that mild symptoms did not establish the object's location. It cannot provide a safe waiting period for another person.
A separate clinical report involving an older oncology patient describes an implant screwdriver retrieved from the stomach after emergency referral. Those two locations required different care. The report also emphasizes the patient's medical history when planning prevention and management.
Give the team an object description
Start with what is known. If you are unsure whether the missing item is a filling, a screw or an instrument, say that. A guess entered as a confirmed part name can make the history harder to interpret.
| Field | Useful information |
|---|---|
| Event | What happened, where you were and approximately when. |
| Object | The known part name, or a clear statement that its identity is uncertain. |
| Available reference | A photograph, package, matching part or device record held by the practice. |
| Symptoms | Coughing, breathing or swallowing difficulty, discomfort and changes since the event. |
| Care already received | Who assessed you and what instructions or imaging have already been provided. |
| Dental contact | The treating practice and a contact who can identify the component. |
This is a communication aid, not a way to decide at home whether an object has passed safely. Follow the medical team's plan for reassessment. If symptoms develop or worsen, seek medical attention rather than waiting for a dental repair appointment.
Keep the medical assessment and dental repair records together
After the immediate concern has been assessed, ask the dental team what is missing from the restoration and how it will be managed. A finding about an object in the digestive tract does not establish whether the remaining crown or connection is suitable for use.
For a surface closure that has come out, see the screw-hole filling guide. For a damaged retaining component, the broken-screw guide explains the different mechanical findings that may need clarification. Keep the object identification, medical outcome and replacement-component record in the same file. The implant record handoff can help when different clinics are involved.
