You Deserve Teeth That Last a Lifetime

Losing a tooth is stressful enough. Then comes the harder question: who do I trust to replace it? Most practices offer implants. Far fewer have the advanced credentials to plan and place them with the precision that actually determines whether an implant lasts — or fails years down the road.

Dr. Horn holds the FAGD designation — earned by fewer than 6% of general dentists in the country — requiring 500+ hours of advanced post-doctoral study and a rigorous board examination. He's been serving Union patients from the same office for over 40 years. He knows what it takes for an implant to succeed long-term, and he has the training to back it up. With an on-site periodontist for complex cases, your care stays coordinated, and under one roof.

Here's what happens when you call us

Step 01

We Listen First

At your consultation, we learn your situation — your health history, your timeline, your concerns. No pressure, no jargon. Just a clear picture of what's possible for you.

Step 02

We Build Your Plan

Dr. Horn uses digital imaging and FAGD-level expertise to design your treatment. Complex bone or gum cases are handled by our on-site periodontist, Dr. Lamantea — no outside referrals needed.

Step 03

You Walk Out Smiling

A natural-looking, permanent tooth you can eat, laugh, and live with confidently — backed by a team that will be here when you need us.
