Administration in Dental Anesthesia

Basically, anesthetic solutions in dentistry are administered by two routes-

  • Intra-oral, meaning into the mouth
  • Extra-oral, meaning outside the mouth on certain areas on the face.

The intra-oral route is the commonly used route of anesthetic administration in dentistry. Depending on the procedure to be performed, the areas of administration vary. If a single, mobile tooth is to be pulled out, then the area around the tooth is singularly anesthetized, whereas multiple tooth extractions or complex surgical procedures require one side of the face to be anesthetized. This is done by injecting the solution close to the nerve.The effect of the anesthesia lasts from 2-4 hours, though it can last longer.
