The word reversed can be misleading
Learners hear this question often because it sounds simple, but the underlying issue is not binary. Recession reflects a positional change of the gingival margin, and discussions about improvement depend on the cause, severity, tissue conditions, and treatment context.
Educationally, focus on what can and cannot be expected
It helps to separate inflammation control from root coverage concepts. Reducing inflammation can improve tissue tone and health, but that is not the same as saying lost tissue position simply returns on its own in every situation.
Why this matters: careful wording protects you from oversimplifying a question that actually depends on diagnosis, anatomy, and treatment planning.
Anchor your answer in fundamentals
A strong study answer usually explains that recession must be interpreted in context, then points toward assessment and treatment planning rather than promising a universal outcome.
