Update mesh collider after changing vertices at run time

Hey guys, So I am modifying the vertices of a mesh at run time and the only way I've found to update the mesh collider is the following: public void updateVertices() { mesh.vertices = vertices; transform.GetComponent().sharedMesh = mesh; } If the modified vertices are known, is there anyway to update only that section of the mesh collider, or are there any other more efficient methods you guys know about?
