The invention discloses a supported artificial tooth. The artificial tooth comprises an external crown; two opposite sides of the external crown are respectively provided with a first groove and a second groove; the lateral wall of the external crown is correspondingly provided with a first elastic clamping component and a second elastic clamping component; one end of the first elastic clamping component and one end of the second elastic clamping component are embedded on the lateral wall of the external crown correspondingly; and the other end of the first elastic clamping component and the other end of the second elastic clamping component are movable and stretch out the external crown through the first groove and the second groove respectively. When the external crown is sleevedly arranged between two real teeth, the first abutting part of the first elastic clamping component and the second abutting part of the second elastic clamping component are abutted on the external walls of the two real teeth respectively, and thus the external crown can be more firmly arranged between the two real teeth through the action of the fist first elastic clamping component and the second elastic clamping component.
