  • Buccal nerve block: It anesthetizes the soft tissue and peristorium buccal to the mandibular molars. It has high success rate.
  • Infra orbital nerve block: This anesthetizes the facial nerves. It is used in the treatment of facial deformities. Infection at the site of injection takes place. Local anesthetics are used to anesthetize infra orbital nerves.
  • Maxillary nerve block: This anesthetizes the maxillary teeth and their soft tissue. It is used to numb the small area. This anesthetizes the skin of the upper lip and cheek.
