“A dentist is someone who can foresee a loss that the patient does not yet feel.”
Emrah Özdemir explains that in dental school, dentistry was taught mostly as repair. Placing prevention before treatment is an established path in dentistry, and he built his own daily practice upon this path. What is missing can be completed with a suitable material, but no material can bring back healthy enamel once removed from a tooth. This section brings together that shift from repair to preservation, his view of the microscope as a way of thinking, and his advice to young colleagues on tissue preservation and patience.
In dental school, we learned dentistry mostly as repair: clean the decay, place the filling, crown what is broken. You clean decay once; but if you remove healthy enamel once, that tooth is now a different tooth.
Under magnification, you see how rough a filling margin that you thought was "clean" with the naked eye actually is. This disturbs you at first, and then makes you a better dentist. The movement of the hand becomes smaller, decisions become clearer. I see the microscope not as a device, but as a way of thinking: magnify first, then decide.
A young dentist's greatest enemies are speed and overconfidence; both end in cutting too much. Look first: magnify, dry, look again; before you decide, be sure of what you see. Then add, do not subtract: if you can solve a problem by adding material, do not even think about cutting the tooth; subtracting is always an open door, there is no need to rush. Practise patience not as a character trait but as a technical skill; waiting for a composite layer, giving the polish one more round, leaving a provisional in the mouth for a week are all patience, and all of them make a measurable difference.
