Use imdistline(). I'm not going to attempt to do it automatically because whatever algorithm I develop might work on that image but then you'll come along with a different x-ray with totally different looking teeth and it won't work on that. Plus you never said where along that black region is the red line supposed to be. Why there? Why not 50 pixels higher, or 30 pixels lower? I have no idea. Plus the boundaries are not sharp so there is a lot of slop in where you might start and stop the line. Therefore, manually specifying it with imdistline(), using your expert knowledge, is the way to go.
