Three connected systems.
Keep Your Teeth is organized into three layers — built to take a patient from understanding their situation, to evaluating their options, to getting real care.
What symptoms mean. How conditions develop. What procedures involve. Built for patients who want to understand their situation before deciding anything.
A structured system for evaluating the decisions that follow a diagnosis. Built around the variables dentists actually use, not defaults or averages.
The practice that built this platform. Dr. Isaac Sun applies the KYT Framework to real patients. For planned treatment, KYT provides written estimates and reviews PPO benefits whenever possible before treatment is scheduled.

The most defensible part
of this platform.
Articles can be written by anyone. Tools can be built. The KYT Framework is the structured system for making dental decisions that KYT developed through clinical practice. It is the intellectual core of everything here.
Should this tooth be saved or removed?
The decision most patients agonize over. What factors actually determine whether saving a tooth is worth it.
Does this need a crown, or can a filling hold?
The threshold between conservative repair and full coverage. What pushes a tooth past the filling threshold.
Is this grinding problem serious?
How force patterns create silent damage over years. When nightguards matter and when they don't.
How did my old dental work fail?
Why fillings and crowns fail. What it means for the next restoration and how to plan for it.
What does bone loss mean for my future options?
How bone levels affect implants, extractions, and long-term tooth retention planning.
Why do dentists keep finding more problems?
The systemic patterns behind cascading dental issues. Why one problem often signals others.
