CASE 3 — 64-year-old patient with GERD and generalized occlusal erosion/cupping, complaining of sensitivity. All of the following are acceptable treatments EXCEPT:

Correct answer: D. Root canal treatment on all teeth

• A. Full crowns are appropriate for severely eroded teeth that cannot be adequately restored with direct restorations.
• B. Fluoride varnish (5% NaF) is a first-line conservative treatment for dentinal hypersensitivity.
• C. Composite restorations can rebuild eroded tooth structure and reduce sensitivity — valid treatment.
• D. RCT on ALL teeth is completely unindicated for sensitivity from erosion alone. RCT is only warranted when pulpal pathology is confirmed. Performing RCT on all teeth for sensitivity is overtreatment and unethical.
