Services
Same Day Smile Makeover
Our proprietary technique delivers permanent dental restorations in a single appointment using advanced CAD-CAM technology. Patients receive crowns, veneers, or full mouth reconstructions without temporary solutions or multiple visits. The process combines digital smile design with in-house milling for precise, natural-looking results that match facial aesthetics.
Dental Implants
Permanent tooth replacement solutions using biocompatible titanium posts that integrate with jawbone structure. We offer traditional implants and All-On-4 solutions for full arch restoration. Our 3D imaging technology ensures precise placement, while same-day options eliminate prolonged treatment timelines typically associated with implant dentistry.
Veneers
Custom-crafted porcelain shells that correct cosmetic imperfections like stains, chips, and misalignment. Our veneers are color-matched to natural teeth using digital shade analysis. The minimally invasive procedure typically requires only one visit for preparation and placement using advanced bonding techniques.
Invisalign
Discreet orthodontic treatment using clear, removable aligners to straighten teeth. Digital treatment planning visualizes the entire correction process before starting. Patients appreciate the convenience of removable trays and the absence of traditional bracket-and-wire systems for mild to moderate alignment issues.
Laser Gum Recontouring
Precision gum tissue modification using laser technology to correct uneven gum lines or excess tissue. The minimally invasive procedure reshapes the gumline for improved aesthetics and better oral health. Patients experience faster healing compared to traditional surgical methods with immediate visible results.

Last week I cracked a molar. Dr. Yang's team got me in right away, assessed the situation, told me my options and I had the tooth extracted. All in just over an hour. In the past I've needed nitrous or lorazepam to deal with anxiety when I've had Novocain. Not with Dr. Yang. I would also need Vicodin to deal with the pain after. Not with Dr. Yang. A Tylenol and Ibuprofen a few hours after extraction was it. Friendly, knowledgeable staff.

State of the art imaging technology. Incredible office with glass walls looking out on trees and the ridge and peak of Mt. Tam. Very soothing. I am fortunate and grateful to have Dr. Yang and his team managing all of my dental needs. Thanks Dr. Yang!

Dr. Lee and his staff are incredibly nice and accommodating. I have been coming here for years and trust Dr. Lee with my teeth. I've gotten a vaneer, cavity replacement & yearly cleanings and each time have had a 10/10 experience! Highly recommend and love that he's local!

Absolutely wonderful experience with Dr. Yang! From my consultation to my appointment Dr. Yang made me feel very comfortable, and took the time to listen to what I wanted. I had a gingivectomy (gum contouring) to even out my gum line and improve symmetry. Additionally Dr. Yang fixed a chip in one of my teeth, and performed some minor reshaping. My results are absolutely incredible, even better than I was hoping would be possible. I have never had a better experience going to a dentist, and I completely recommend Dr. Yang to anyone looking for a fantastic dentist!

Dr. Leo has been my dentist for 7+ years now and I've always had good experiences with his clinic. Taren is my hygienist and I look forward to getting my teeth cleaned by her!

My family has been going to Dr. Yang for probably 10 years now, he is a very thorough, modern and friendly dentist. His staff is is always friendly and accomodating, and cleanings are easy and quick. His location is very convenient to downtown Mill Valley, with ample parking. We'd recommend Dr. Yang to anyone new to the area looking for a dentist.

Posting on behalf of my mother - Ruby C (who doesn't have a google account) - Dr Leo Yang is the BEST in CA! I needed extractions and crown work done and have not had good experiences in So. Cal. (I live in So Cal but go to Nor Cal regularly), I decided to give Dr Yang a try and have been going to him for the last 9 months every time I visit. During our initial visit, Dr Yang did a thorough and detailed exam and discussed a plan and provided options. Dr Yang's office is equipped with the state of the art technology - 3D x-ray scans, photographs and in house crown making machine. Dr Yang extracted a tooth (painless), replaced some crowns and replaced the extracted tooth with implants (no pain either).

During one of my visit, I lost my veneer and he was able to make a new one on the same day and I was able to proudly smile with my teeth showing. Overall, I am very happy with the care that has been given to me, the professionalism, the efficiency and the latest technology that Dr. Yang used to get the job done. THANK YOU Dr Yang and Staff for making me so happy!
