Memorial Day weekend on Dr. Jefferies' family farm! 🌾

Between prepping the garden, taking in the stars, and chasing sunrises, it was the kind of weekend that fills your cup. His son Henry spent time planting alongside his Lolo (grandfather), and even Duke the pup took time to stop and smell the flowers! 🐶 🌸

Grateful for quiet moments, family traditions, and a bit of sunshine before summer officially begins! 💙

Smiles on the Run!

The Mark S. Jefferies team laced up and crossed the finish line at the Run Thru Reston 5K this past weekend! 🏃We're proud to have taken part in this amazing event to help raise money for college scholarships in our community.

Dr. Jefferies recently attended the Bioclear Alumni Summit 2025 in Scottsdale! ✈️ This annual event brings together dentists dedicated to advancing modern, minimally invasive techniques, and Bioclear is one of the most exciting tools we have.

So what is Bioclear? It’s a technique that allows us to repair chipped, broken, or worn teeth—without drilling down healthy enamel or placing a crown.

Some of the benefits include:
🦷 Preserves more of your natural tooth structure
🦷 Strong, bonded restorations designed to last
🦷 Seamless, natural-looking results
🦷 Less invasive—and often more affordable—than traditional options

The images shared here were presented at the summit and show real cases completed using the Bioclear method. From saving teeth that would’ve otherwise been extracted to repairing cracks or closing gaps, it’s a technique that continues to change the way we treat and restore smiles.

Curious if Bioclear is right for you? We’d love to talk about your options
