Are MRI scans necessary before proceeding with surgical procedures for trigeminal neuralgia?

The most important factor would be the material of your implants. MRI utilizes magnetic fields and with that, it reacts with magnetic materials such as iron and cobalt. These days, almost all implants are made from medical-grade titanium. Titanium is paramagnetic, meaning that it does not react with the MRI's magnetic fields. With that, it is completely safe for someone with dental implants to go for an MRI. Various studies found that the risk of titanium implant-based complications is very low [1].

Trigeminal neuralgia is a type of severe facial pain whereby sudden, electrical or stabbing pain that is felt on one side of the face. There is often a trigger, such as eating, brushing teeth, or even talking. The pain comes from the trigeminal nerve usually because it is compressed by a blood vessel, although other causes such as tumours or multiple sclerosis must be excluded. The first-line treatment of trigeminal neuralgia is with medications.
