If the nerve block is unsuccessful, or if the exact location of the infraorbital foramen is unclear, a field block is a useful alternative.

To perform a field block, inject 5 mL of anesthetic solution into the upper buccal fold in an arc-shaped distribution. Massage the area for 10-15 seconds to speed the onset of anesthesia. Although this technique is not as precise as the previously discussed nerve block, it often accomplishes the same anesthetic effect.
