I am confident that you will find our dental specialists are experienced, caring dentists that are the right fit for your whole family. We pride ourselves in caring for you as a person and not as a set of teeth. We are honest and up front about the treatment you need and the treatment you don't.

And no matter what your situation, you can be confident in knowing we will never pressure you into anything you don’t feel comfortable with and you will always know your options. We do not judge your habits or the state of your teeth; we move forward from the day we meet and work together to make you feel comfortable with your oral health.

I invite you to come experience the difference and see for yourself what sets 425 Dental apart.

What patients have to say

"Dr. Oleg and his team are amazing! I just finished my Invisalign treatment and my teeth are perfect! They are so flexible with your schedule and take the extra time to make sure each patient is comfortable. I couldn't have asked for better or more kind service, they are simply the best. Thank you to the entire team!"
"This was my first experience at the dentist. They made me so comfortable and made sure that the work being done made me feel relaxed. Easiest appointment set up and insurance coverage explanation. They are a fantastic Crew."
"Oleg, Nikole and their whole team are always so warm, welcoming and professional. Their care for all my needs, short and long term, have always been very high. Their work in the more than 2 years I have been in their care has been the best I've ever had. Their techniques and state of the art tools, facility and chair-side manners have consistently reduced my anxiety in receiving dental care to where now I look forward to my appointments."
"The staff is friendly and professional. Dr. Oleg explains everything clearly, and is always responsive when I text him. Rebecca who takes care of my Invisalign treatment is courteous, friendly and very knowledgeable. This office has certainly changed my perspective on dentist visit for the better."
"What a nice experience here. Super gentle, super friendly. Didn't make me feel worse for the shape my mouth is in. Took time to answer my questions, with words I actually understood:) I will DEFINITELY be coming back to this office!"
