What a second opinion is, and what it is not
A second opinion is an independent clinical review of a plan you already hold: an examination, a careful reading of your radiographs, and a conversation about the reasoning behind each proposed item. It is not an audit of another clinician, and it is not an invitation to take sides. The subject of the appointment is your mouth and the evidence, not the person who wrote the plan.
It is also not a promise that anything will change. In one review of 286 patients referred from primary care to a large academic medical centre, the referring diagnosis and the final diagnosis matched exactly in 12 percent of cases, were refined or better defined in 66 percent, and were distinctly different in 21 percent.[1] That study was in general medicine rather than dentistry, and a treatment plan is not the same thing as a diagnosis, so the numbers do not transfer directly. The pattern is what matters: a second look usually sharpens a picture rather than overturning it, and that is a reassuring finding rather than a disappointing one.
