What a brilliant use for a classic drill...!!
SWMBO remembers, as a child, going to the dentist in N Ireland and the drill being treadle operated, rather like an old sewing machine!
Your comments on modern dentistry are well made... I have a fair amount of amalgam in my back teeth, but bit by bit it is being replaced with a UV Cured material.
One tooth split, the "wedge effect" of the filling and I had a crown fitted.
At least at 65 I have all my teeth, which compared to my parents generation, is impressive.
My daughter, (31) has never had a filling, but has had some repair work, damage caused by a cycling accident...!
