Three Surfaces: The Decision Point Between a Filling and a Crown
A three-surface composite filling (D2393) represents the upper boundary of what's typically appropriate for a filling. At this extent of decay or damage, the tooth is losing a significant amount of natural structure — and the conversation about whether a filling or a crown is more appropriate becomes clinically relevant.
The filling vs. crown decision at three surfaces is genuinely a judgment call that depends on how much cuspal support remains, the location of the tooth, and the patient's bite forces. What matters is whether the recommendation is driven by your clinical situation or by the practice's financial incentives.
Longevity considerations are important here. A large composite filling is more likely to fail, crack, or need replacement than a crown on the same tooth — but it's also less invasive and significantly less expensive. If the tooth already has a root canal, a crown is almost always the appropriate choice over a large filling.
What to Watch For
If you're being quoted a three-surface filling for a tooth that already had a root canal, ask specifically why a crown isn't being recommended. After a root canal, a large filling leaves the tooth structurally vulnerable to fracture — and a fractured tooth after a root canal often cannot be saved.
