In order to develop mixing and application capsules known from the prior art, so that limitations regarding the dental preparations that can be obtained are overcome, a mixing capsule (22) for producing a dental preparation is proposed in which the mixing capsule (22) has: a capsule body (1) having a mixing chamber for receiving a mixing component and for mixing the dental preparation from the mixing component, a first fluid and a second fluid and having an outlet opening (4) for expelling the dental preparation, a first cavity for receiving the first fluid, a first piston body (2) which delimits the mixing chamber in the capsule body (1) and which has a first passageway for guiding the first fluid from the first cavity into the mixing chamber, a second cavity for receiving the second fluid and a second piston body (2) which delimits the mixing chamber in the capsule body (1) and which has a second passageway for guiding the second fluid from the second cavity into the mixing chamber.
