Block anesthesia is achieved by the dentist injecting the anesthetic solution into the nerve trunk.
A nerve block is when numbing medication (local anesthetic) is injected close to particular nerves to lessen pain during and after surgery in a particular area of the body. Your anesthesiologist may implant a "nerve catheter" for a particular type of surgery, which can be used to continually bathe the nerves in numbing drugs for two to three days following the procedure. Your postoperative pain is reduced by a nerve block. Compared to IV pain medicines, it is more efficient. Even if you have access to the meds, you won't require as many oral or IV painkillers because your pain is less severe.
