Local Anesthesia

Local anesthesia renders part of the body insensitive to pain without affecting consciousness. In other words, it only numbs a small part of the body such as a tooth or an area of skin.

Local anesthesia allows patients to undergo many surgical procedures without significant pain or distress. In some cases, it is used in combination with other forms of anesthesia, such as IV sedation and nitrous oxide for the patient’s comfort and ease of surgery.

Local anesthesia involves the injection of numbing medication into the mouth. Once the medication has taken effect, it will inhibit sensations such as pain, touch, temperature and muscle control. However, it will not block the sensation of pressure which is sometimes felt during a tooth extraction.

The anesthesia will persist as long as there is a sufficient concentration of local anesthetic at the affected nerves. The anesthetic effect may persist from less than an hour to several hours.

There are no major contraindications to using local anesthesia.
