A sulcus impression tip for use in injecting dental impression material for making dental impressions. The apparatus includes a body having a gripping portion and a discharge tip. The body includes a needle cannula in fluid communication with a flange, wherein the flange receives and holds the dental impression material and is secured in the interior surface of the gripping portion. The discharge tip has a bore there through which permits a friction fit with the outside diameter of needle cannula. The length of the needle cannula is approximately longer than the length of the discharge tip. The body further defines an angle such that when the dentist is holding the gripping portion, the angle permits the discharge tip and needle cannula to be positioned for easy access in the oral cavity by the dentist. The discharge tip is sized and shaped to effectively separate the gum from the tooth in the selected region so that the needle cannula is positioned to permit exact positioning for placement of the dental impression material along the sulcus.
