Restoration thresholds.
when structure changes the answer.
Sometimes a tooth looks like it only needs a filling. But if too much tooth structure is missing, the real question becomes whether the tooth can survive normal chewing over time.
A restoration threshold is the point where the same tooth stops being a filling decision and becomes a structural risk decision. In the Keep Your Teeth Framework, we evaluate what remains, how force will concentrate, whether timing is helping or hurting, and what the tooth is likely to do over the next decade.

§ 02 · Evaluation
How the KYT Framework evaluates restoration thresholds.
How much tooth is left. And where is the missing structure located?
Will force concentrate on thin walls, old margins, or crack-prone zones?
Is this the moment to reinforce, or can careful monitoring stay safe?
What fails first in 5 to 10 years: the restoration, the tooth, or the margins?
Why thresholds change with time
Teeth don't get stronger with age. Enamel thins, dentin fatigues, microcracks accumulate, and old margins become stress risers. A borderline tooth often becomes predictable only after you decide whether you're reinforcing the structure or accepting a higher failure risk.
