About Isthmus Dental, Ltd

Isthmus Dental, Ltd is at 122 East Johnson Street in Madison, Wisconsin — a location on the isthmus that gives the practice its name: the narrow strip of land between Lake Mendota and Lake Monona on which the University of Wisconsin campus, the State Capitol, and much of historic Madison's residential character sit. East Johnson Street is in the near-east side of the isthmus, accessible from the Williamson Street corridor, the Marquette neighbourhood, and the Capitol Hill and Langdon Street communities.

The practice describes its approach as providing personalised oral health care tailored to each patient's unique dental needs and goals, with a focus on the patient understanding their own oral health status and options. In an isthmus Madison practice serving the diverse demographic of UW-Madison students and staff, Capitol Hill professionals, and near-east side long-term Madison residents, the range of dental histories and treatment goals is wide — from first-time adult patients establishing care through experienced dental patients managing complex long-term restorative histories.

Dental sealants for paediatric preventive care are listed alongside implants and periodontal care — a scope that covers the preventive starting point of a patient's dental care through the later restorative and maintenance needs. In the Williamson Street and Marquette neighbourhood demographic, which includes a mix of young professionals, established east-side homeowners, and UW-affiliated faculty, the combination of preventive and restorative care within the same practice relationship provides the longitudinal dental care that these communities value.

Emergency dentistry covers the acute presentations in the isthmus community. Dental bonding and veneers alongside teeth whitening address the cosmetic requests. Crown and bridge restorations and dental fillings complete the restorative maintenance scope for the East Johnson Street patient community.

For isthmus Madison, Marquette, and Williamson Street patients on East Johnson Street who want a personalised general dental practice with implants, sealants, and emergency dentistry in the heart of Madison's historic isthmus community, Isthmus Dental's 122 East Johnson Street address provides that combination.

From first contact at Isthmus Dental Ltd, our Madison dentists are committed to your individual attention and provide personalized oral health care tailored for your unique dental needs and goals. We create the ultimate stress-free and comfortable dental experience for you. Your health and comfort are our top priorities, and we do what it takes to help every patient understand their symptoms and treatment options in a relaxed office setting. Achieving quality dental care shouldn't be difficult,

Dr. Vu is an excellent dentist. But he also has a great chair-side manner. He always explains the work he is going to do in advance and makes sure you are not having any discomfort. John Talis

Rude. I called to ask for an estimate, and the lady wouldn’t even try. She refused to run an estimate. Rude!!! I used to go here, but they have definitely changed for the worse. I wish they cared like they did before.

I've been going here for over ten years. Everyone is so lovely, and Dr. Wozniak is the best dentist I've ever had. I have a condition that makes local anesthesia less effective, and I love how the team works with me to ensure that any pain is tolerable. They take time to explain things and offer choices. I feel comfortable and supported in advocating for myself, and I and find the staff here to be trauma-informed and deeply kind.

I recently went back to Isthmus Dental after the Covid-19 shut down. The staff were very well covered with protective equipment and I felt very safe. They took my temperature and took an oxygen reading (first for that). The care was good as always. They got me in the chair right away and kept my discomfort to a minimum. I was getting a tooth prepped for a cap so there was a lot of drilling. I've been going here for a long time and find them to be very professional and thorough.

All of my experiences at this dental office have exceeded expectations. Currently, I am receiving care for Invisalign. I am in excellent hands with Debora! I enjoy going to my appointments. Everyone at the front desk is welcoming and conversational. I leave with a spring in my step! Great neighborhood business.

The dr was incredibly kind and easy going through my entire tooth filling. I never felt shamed about having a cavity. I didn’t even feel the numbing shots, and the entire process was relatively painless! He even stayed long to make sure everything felt normal!

This is the best dentist I have ever been with. My hygienist is like seeing a friend who’s looking out for you, taking the time and care to make you feel comfortable. One time I had dental surgery somewhere else that was causing pain and couldn’t get them to figure out issue. I remember Dr Vu saying “you don’t have to live with pain. I’ll refer you and we’ll fix it”. And they did. Truly a dental office full of the best people.
