The invention relates to an applicator instrument for applying dental compounds. The applicator instrument comprises an instrument head (11) with a support structure (12) and with a plurality of projections (14) formed on the support structure (12). The projections (14) are elastic and, in relation to a height extent, have less stiffness than the support structure (14). Between them, the projections (14) enclose a receiving space (15) for the dental compound. According to the invention, the projections (14) have a planar configuration and, in relation to a width extent, are arranged substantially parallel to one another. The greatest diameter of the instrument head (11) is between 2 mm and 3 mm. With the applicator instrument according to the invention, it is easier to apply the dental compound in dosed amounts and to spread the dental compound across the surface that is to be treated.
