A method, a user interface and a system for use in determining shade of a patient's tooth, wherein a digital 3D representation includes shape data and texture data for the tooth is obtained. A tooth shade value for at least one point on the tooth is determined based on the texture data of the corresponding point of the digital 3D representation and on known texture values of one or more reference tooth shade values.
