Why Titanium Implants Don't Trigger Metal Detectors
Airport metal detectors work by sensing disturbances in an electromagnetic field — and they are tuned to react to ferromagnetic metals like iron and steel. A dental implant is made of titanium, a metal with very weak magnetic properties. On top of that, the implant itself weighs only about a gram and sits anchored inside your jawbone, beneath the gum.
The combination of a non-magnetic metal and a very small amount of it means walk-through detectors simply do not respond. Patients with hip or knee replacements sometimes trigger alarms because those implants contain far larger amounts of metal — a single tooth implant is a different situation entirely.
What About the Full-Body Scanners at Changi?
Modern airports, including Changi, also use millimetre-wave body scanners. These image the surface of the body, so an implant buried in your jawbone does not show up. There is no need to declare your implant, and no implant card or doctor's letter is required for flying — something patients regularly ask us before long trips.
Are Dental Implants Safe for MRI Scans?
Yes. Titanium is MRI-compatible at the field strengths used in hospital scanners, so the implant will not shift or heat up during a scan. At most, it may cause a small artefact (a blurry patch) on images taken near the jaw. Two practical notes:
- Always tell your radiographer about any implants or dental work before an MRI — this is standard screening practice.
- The crown on top of an implant is usually zirconia or porcelain, which contains no metal at all.

Other Dental Work Travellers Ask About
Metal fillings, crowns, bridges and braces wires also pass through security without incident — again, the metal quantities are far too small. Removable dentures with metal frameworks can stay in your mouth at the security gate too.
