The most permanent solution would be to attach the ceramic tooth to a small metal angle bracket. This can then be attached inside your mouth using small yellow rawlplugs and screws.
Don't use the drill on hammer when you drill into the roof of your mouth as the vibrations will make your vision go blurry - best to use a tungsten tile drill on non hammer for this. Also don't be tempted to use paraffin or other cutting agents to speed up drilling as these will make you gag. Regarding drill depth it's usually best to stop when you get a spurt of cerebrospinal fluid. If your left leg starts to try walking on its own you have drilled too far, a couple of matchsticks for packing will come in handy in this eventuality.
Nearly forgot, you'd be better off using stainless steel screws as mild steel tastes a bit sour when it rusts.
