Inhalable Local Anesthesia Could Replace Painful Needles at the Dentist

Inhalable Local Anesthesia Could Render That Needle Obsolete

Your dentist may soon be moving from needle drugs to a snort-able variety. Researchers have found that local anesthesia delivered through an inhalable nasal spray quickly travels down one of the face’s primary nerves to the mouth, which could be more effective than injecting it into the gums with a needle.

The discovery was made when researchers took a closer look at the trigeminal nerve, which brings feelings to the nose, mouth, and face. Scientist have long known about the trigeminal nerve, but they’d never thought to see whether it might be a good conduit for intranasal drugs.

But oral surgery is just the beginning. A new breed of drugs concocted for intranasal delivery could treat all kinds of face-oriented ailments, from common toothaches to migraines to trigeminal neuralgia, a condition that results in pretty severe facial pain. For most of us, it means that “tiny pinch” the dentist always describes right before jabbing a needle into your gums may be a thing of the past. So in a sense, the discovery also clears up a certain pain in the neck as well.
