Failure patterns.
how dentistry fails over time.
Failure patterns explain how dental work breaks down. Not in theory, but in real mouths over years.
In the Keep Your Teeth Framework, failure is usually predictable once you know the structure, forces, and timing.

How the KYT Framework evaluates failure patterns.
Failure usually begins at the weakest geometry: thin cusps, margins, connectors, or root surfaces.
Load concentrates at interfaces. Stress direction determines where breakdown starts.
Reactive treatment often stabilizes temporarily. Early stabilization preserves structural reserve.
Designs built for decades behave differently than solutions built to solve immediate symptoms.
Repeatable failure models
- ·Crowns: margin leakage, cement breakdown, root fracture under accumulated load.
- ·Fillings: cusp fracture and crack propagation as structural reserve decreases.
- ·Root canal teeth: brittleness and vertical fracture when structure is thin.
- ·Implants: overload, crestal bone loss, and inflammation when force and biology misalign.
The redo cascade.
Every redo removes more structural reserve. Filling becomes larger filling. Large filling becomes crown. Crown becomes root canal and crown. Root canal tooth fractures and becomes extraction. Extraction becomes implant. Each step can be appropriate, but each step reduces remaining margin. Failure patterns compound when aging, force, and timing are misaligned. This is structural math, not pessimism.
