Fountain Valley · Built around PPO patients
PPO dentistry with the math written down.
We pre-verify your coverage, file every claim, and bundle the procedure fee, the insurance application, and any financing into one written estimate before treatment is scheduled.
Every recommendation comes with the structural reasoning behind it, so you know exactly what you are paying for and why.

Book PPO VisitWhy this matters
Starting should feel clear, not overwhelming.
The first step should help you understand what happens next.
That is why we keep the first step simple.
A lot of people delay care because they are not sure what is urgent, what can wait, or where to begin.
We start by helping you understand what is going on, what matters now, and what your options are.
If something is simple, we say so. If something needs attention, we explain why.
You are not pushed into treatment. You get a calm, clear starting point.
What we do before treatment
Before any treatment is scheduled, we put it all in writing.
Most patients have been burned at some point: surprise charges, claim disputes, treatments that ended up costing more than expected. We built KYT around removing those surprises before they happen.
Step 1
We verify your PPO coverage before the visit.
We call your plan, confirm your deductible, your annual maximum, and your remaining benefits, and map exactly what each procedure costs you out of pocket.
Step 2
We submit pre-authorizations on every major procedure.
For crowns, root canals, implants, and other major work, we file the paperwork and only schedule treatment after your insurance confirms coverage in writing.
Step 3
We bundle everything into one written estimate.
The procedure fee, the insurance application, and any financing options get written into one document. You see what is covered, what is not, and exactly what your portion is.
Step 4
We walk you through it before anything is scheduled.
You see the structural reasoning behind each recommendation, the cost line by line, and the timeline. No pressure, no rushed decisions. You decide when to move forward.
