Local anesthesia (often called Novocain) stops sensation, allowing what would have been painful procedures to be accomplished painlessly. Unfortunately, there is often discomfort associated with traditional injection of local anesthesia, as well as the feeling of altered sensation to the tongue and lip. By using a technique called interseptal anesthesia, it is possible to anesthetize the area being worked on specifically, without symptoms to the lip or tongue.

Since the technique involves very small amounts of anesthetic delivered to the site being worked on, there is very little waiting for the effect of the anesthetic. It is an almost painless procedure. When combined with Nitrous Oxide (Laughing Gas) it is painless.
