For Class I composite replacements, how do dentists identify where the filling is on the occlusal and differentiate between filling and enamel?

Assuming there are no identifiable filling margins on the occlusal surface, how does a dentist identify where to drill exactly on a molar?

Phosphoric acid etch the entire occlusal surface?

Usually we have magnification with full lighting. The filling to be replaced usually have numerous visible defects and fillings reflect light differently than enamel. I etch only on the surfaces to be bonded. If the filling is intact and has no defects on x-rays, then the filling does not need to be replaced (unless you're in a learning facility and working on a typodont, then look for the different light reflection).
