You can remove the mesh object from the scene in the following manner.

var cubeMesh = new THREE.Mesh(geometry, material);

scene.add(cubeMesh);
//...

someDeleteFunction() {
    scene.remove(cubeMesh);
    cubeMesh.geometry.dispose();
    cubeMesh.material.dispose();
    cubeMesh = undefined; //clear any reference for it to be able to garbage collected
}
