About River Valley Dental

Dentistry Reimagined

What if going to the dentist felt less like a healthcare appointment and more like walking into a place where people genuinely know you, care about you, and are invested in helping you become healthier for life?

That’s the experience we’ve worked tirelessly to create at River Valley Dental.

Nestled inside a beautifully restored 1860s farmhouse in Sergeantsville, New Jersey, our practice feels unlike any dental office you’ve visited before. Sunlight pours through oversized windows. Living plants soften every corner. The atmosphere is warm, welcoming, and remarkably un-clinical.

Yet beneath the charm of our historic home lies some of the most advanced dental technology available today.

We intentionally blend high-touch hospitality with high-tech dentistry because we believe exceptional care should feel both deeply personal and clinically extraordinary. For many of our patients, River Valley Dental becomes more than a dental office. It becomes their dental home.

“I have come to except the highest levels of professionalism from the front desk team, to the hygienists, and the doctors. Start to finish, a stellar experience every time. The care is thorough and takes into consideration different levels of comfort.
I would not go anywhere else.”

- Michael

River Valley Dental — What Makes Us Different
The Front Room

What Makes River Valley Dental Different?

There are plenty of places to get your teeth cleaned. What’s much harder to find is a dental team that sees you as a whole person, invests relentlessly in its own growth, and combines cutting-edge technology with genuine human connection. That’s what makes River Valley Dental different.

I.

Unreasonable Hospitality

Exceptional care begins long before treatment starts — a warm greeting, a familiar face, a conversation that doesn’t feel rushed. A team that remembers your family, your career, and the details that matter to you.

II.

A Team Committed to Growth

CANI — Constant And Never-Ending Improvement. Every team member, from doctors to patient care coordinators, invests in continuing education and monthly in-office training.

III.

We Treat More Than Teeth

Airway health, sleep quality, inflammation, nutrition, and stress are part of the conversation. Our goal isn’t simply to repair teeth — it’s to help people live healthier lives.

The Workshop

Big-City Technology. Small-Town Heart.

First in Hunterdon County

River Valley Dental was the first practice in Hunterdon County to introduce Solea® laser dentistry — allowing many procedures to be completed comfortably, without injections or traditional drilling.

  • Same-day CEREC digital crowns
  • 3D digital scanning and treatment planning
  • Diagnodent laser cavity detection
  • OralID oral cancer screening technology
  • Advanced digital imaging
  • Solea Snore Therapy
  • CandidPro Clear Aligner System (clear removable braces)
  • GLO Teeth Whitening System

Our investment in technology isn’t about having the newest gadgets. It’s about more accurate diagnoses, more comfortable treatment, and better outcomes.

The Parlor

Relationships Matter

Many of our patients have been with us for years, and have referred friends, neighbors, coworkers, and entire generations of their families. We know dentistry is ultimately about people — and that trust is something we never take for granted.

“What’s best for the patient sitting in front of us?” That’s the standard we hold ourselves to every day.

The Rooms of the House

Comprehensive Care Under One Roof

Our patients rarely need to be referred elsewhere. From preventive care to advanced restorative and cosmetic treatment, everything is designed to support long-term oral and overall health.

Cosmetic Dentistry

Veneers, smile makeovers, clear aligners, professional whitening, and cosmetic bonding — from subtle refinements to a complete transformation.

Restorative Dentistry

Same-day CEREC crowns, dental implants, bridges, and tooth-colored restorations that look natural and last.

Preventive & Wellness Care

Periodontal therapy, oral cancer screenings, saliva testing, laser cavity detection, and personalized prevention.

Surgical Services

Extractions and dental implant placement, completed in-office with continuity of care and a team you trust.

Airway, Sleep & TMJ Care

Individualized treatment for jaw pain, teeth grinding, and airway-related sleep concerns.

Advanced Oral Cancer Screening

OralID fluorescence technology for enhanced early detection.

No matter what brings you through our doors, our mission remains the same: helping you leave healthier, more comfortable, and more confident than when you arrived.

The Porch

Care That Puts People Before Insurance

We believe insurance is a benefit — not a treatment plan.

With insurance

We participate with most PPO plans, submit claims on your behalf, and help maximize your available benefits — while treatment recommendations stay driven by health, function, comfort, and long-term outcomes, not coverage limits.

Without insurance

Our Plan For Health Membership Program offers an affordable alternative to traditional dental benefits, alongside flexible payment through CareCredit, Cherry, and HSA/FSA accounts.

Experience the difference for yourself.

Dr. Mark Bydalek

FOUNDER, RIVER VALLEY DENTAL

“It is with great personal satisfaction and our Bydalek Dental team’s privilege to offer quality compassionate care to our community. We all know that where we live is nothing short of extraordinary. Our neighbors are hard working, engaged, interesting, and above all nice people that demand and deserve the best. We’ve worked hard as a family and team to build a service business that we are proud of and enjoy.”

Dentist. Artist. Farmer. Father to two awesome kids, Alexandria and Ian. Husband to Maureen. Grateful son. Diehard Hokie and Philly fan. Skier. SSI Diver. Outdoor enthusiast.

‍Dr. Bydalek was raised in a military and artistic family and grew up travelling. Declining a scholarship to pursue an art degree in his senior year in high school, Dr. Bydalek decided to combine his artistic talent from his mom’s Dutch side of the family, and follow in his dad’s footsteps, a retired Air Force dentist, to pursue the field of dentistry where he felt he could use his skills to make the greatest impact.  

Dr. Bydalek obtained his undergrad at Temple University and then decided to remain at Temple for his doctorate at the Kornberg School of Dentistry. His passion in dentistry is cosmetic design because creating a new smile, or making a tooth that actually looks and functions like a tooth, takes time, talent and care to get it right. Staying on top of the latest advancements in dental care theory, technique and technology remains priority in his office and that is why he continues to invest in it. RiverValleyDental was the first practice in Hunterdon currently to offer Solea drill-less laser dentistry; in addition, the office has CEREC digital crown and implant dentistry, 3D Scan technology, Diagnodent laser cavity detection, and more.

Somewhere in throws of raising a family and beginning to really understand and value the necessity of proper nutrition, healthy lifestyle including enough sleep and exercise, Dr. Bydalek has decided to take on the current recommendation by the American Dental Association community to have a conversation with his patients with regard to their overall health and take ownership in playing a role in their overall care.

Dr. Andrew Tang

DENTIST, RIVER VALLEY DENTAL

Dr. Andrew Tang was born and raised by hard-working immigrant parents, who taught him the value of hard work and service to others. Growing up in Freehold, New Jersey, Dr. Tang held an intense interest in science, pursuing a degree in biotechnology at Rutgers University. During college, he assisted his grandfather, a now-retired general dentist, and found that he loved dentistry’s unique blend of artistry and medicine.

A lifelong Scarlet Knight, Dr. Tang obtained his doctorate from the Rutgers School of Dental Medicine. During his time there, he was very involved in dental research and was recognized for his work as part of the ADA/Dentsply Sirona Clinician Research program, speaking at dental conferences across the US. Since graduation, he has completed a residency training program at Hackensack University Medical Center and has worked in public health for underserved communities.

Outside of dentistry, Dr. Tang loves spending time with his fiancé, Steph, and their affectionate dog, Cosmo. An avid musician, he spends his days off playing guitar and writing/mixing electronic music.

With the firm belief that advances in technology can make quality dental care more comfortable and more accessible to patients, Dr. Tang is ecstatic to join Dr. Bydalek and RiverValleyDental’s commitment to excellence.
