Dr. Tang and Marissa, the hygienist, are impeccably thorough, exceptionally friendly, and highly professional. They explain everything clearly and in a way that’s easy for a layperson to understand. The front office staff are equally welcoming and helpful. I travel all the way from NYC for my dental checkups—and it’s well worth it.

I had a great experience at my dental appointment today. The dentist was honest and took the time to explain everything in detail. It was clear they cared about my dental health rather than just trying to sell me on treatments. The staff was also friendly and professional from start to finish. Highly recommend this office if you’re looking for a dentist who’s knowledgeable and transparent.

Never did I think I would give a dentist office five stars since I have some general anxiety going to a dentist. This place is great every single person is genuinely nice and everyone seems to do their job very well. I had the most thorough examination that I’ve ever had. I also love the fact that this is a small business and not a big dental corporation.

I had a great experience with dr Bydalek he couldn't have been nicer along with his assistant. He charged me nothing for my visit due to being in the military . I look forward to seeing them again

Today I had a check up and hygiene appointment with Marissa. She is excellent at her work and focused completely on my oral health and comfort during the procedures. My teeth are immaculately clean and I have a clear plan for future treatment of a couple issues.

The staff at River Valley Dental are friendly, knowledgeable, and efficient.

Excellent visit for a cleaning today as always. The staff is friendly and caring. Staff also takes the time to update me on insurance concerns. Treatment and cleanings are just short of being a fun thing to do. I recommend this office to anyone looking for great dental care.

Marissa is my hygienist, and she is perfect. Always so kind, friendly, and gentle on my teeth. This office has the most current technology, making any procedure done a breeze. Lights to screen for oral cancer and lasers instead of drills for cavities which means no novocaine. I have been seeing Dr. B since I was a young child, and I have no intention of ever switching.

I could not be happier with my choice. River Valley Dental has an incredible team. They are all extremely pleasant people, very skilled, with state-of-the-art equipment, and they understand the importance of making dental work as pain free and comfortable as possible. I am so lucky to have found a new dental office with all of the best characteristics of my previous one!

Dr Bydalek and his staff are the best! They take the time and care about their patients.
This was the first time that Marissa was my dental hygienist.She took the time to review my records and got to know me before she worked on my gums and teeth. She made sure that I was comfortable and not in any pain or discomfort.

So friendly and welcoming always! Went for a 6mo cleaning and felt like a Spa Treatment! "Really!!" Soothing water fall experience in the waiting room, great mix of music playing in the background, cooling/moisturizing under eye patches placed on my face, and at the end a lemon oil scented warm cloth to wipe face clean!

Dr Bydalic’s dental practice is the best that I’ve encountered over the many years of dental care. He has updated equipment. His staff are all very professional. The office is very clean and sanitary. And I think his prices are very fair and even quite a bit lower than some others I’ve heard about. I’ve been going to him for over 30 years and I’ve never had a problem.
