Membership and pricing02·Approach
What makes KYT different.
Not every dental office approaches care the same way. Here is what distinguishes how KYT works.
Tooth preservation first
We look for ways to save a tooth before removing it. Extraction is a last resort, not a default.
Full-mouth planning
We evaluate the whole picture (bite, bone, gums, and existing work) not just the tooth that hurts.
CBCT + iTero scanning
3D cone beam imaging and digital scanning for diagnoses that 2D X-rays alone can miss.
Clear explanations
What we found, what it means, and what we recommend. In plain English, before anything is scheduled.
PPO + membership
We accept most major PPO plans and offer a membership plan for patients without insurance.
Same-day emergency care
Tooth pain, broken tooth, lost crown. Same-day appointments available for urgent situations.

Before we recommend treatment, we look at the whole picture.

Insurance and cost.
We work with most PPO plans and offer options for patients without insurance. Clear estimates before treatment.
