A method, with requisite tools, for producing a boat-shaped adhesive crust, contoured for dental composite filling, including steps of: removing decay from a tooth, and exposing new tooth surfaces; arranging a flexible metal band, supported by at least one wedge, around the tooth, so an inner surface of the metal band and new tooth surfaces form a cavity and provide a contour for the restored tooth; applying acid solution to new tooth surfaces, dissolving inorganic material, leaving organic matrix on new tooth surfaces; coating new tooth surfaces and the inner surface of the metal band with adhesive films; providing a pressing tool having at least one tip; pressing the coated metal band, with the tip, against an adjacent tooth, creating a desired contact area of the restored tooth; and simultaneously with pressing, light-curing the adhesive films, forming the boat-shaped adhesive crust, having desired contact area and sufficient strength to maintain it, when the tip of the pressing tool is removed.
