  • Method of shortening effective time of anaesthetic
    Patent number: 5095023
    Abstract: A method for reducing residual numbness experienced by dental and medical patients infiltration injection in the gums or mouth region with anaesthetic. After a dental or medical procedure, such as filling or extracting a tooth, a quantity of niacin is placed against the gum or other area where the anaesthetic was initially injected. The niacin enters the blood vessel walls to expand the blood vessels, thus to effect an increased flow of blood for more rapid transport of anaesthetic from the numbed area.
