Visiting the dentist shouldn’t feel confusing or overwhelming, and that’s the idea behind Salt and Smile Dental Co. in San Diego. As your trusted dentist in San Diego, Dr. Shawyan “Yaz” Yazdanmehr built this practice around clear communication, thorough care, and a calm environment where you always know what’s going on with your oral health. What this really means is that you get a dentist who takes the time to explain your options, answers your questions honestly, and helps you make decisions without pressure.
Salt and Smile Dental Co. focuses on preventative dentistry first, catching problems early and keeping your teeth healthier over the long run. As a leading dentist in San Diego, Dr. Yaz offers comprehensive services in one place, including dental implants, root canal therapy, cosmetic dentistry, and clear aligners. Whether you’re looking for a dependable general dentist, a second opinion you can trust, or simply a place where you won’t feel rushed or judged, this is a practice built to meet you where you are.


Raised in Carlsbad, Dr. Yaz has a deep connection to the San Diego community. As a trusted dentist in San Diego, after studying at UCLA and earning his dental degree from the University of the Pacific, Dugoni School of Dentistry, he gained valuable experience in Chicago before returning home to serve his community.
Outside the office, he enjoys surfing, pickleball, hiking, playing guitar, and spending time with his wife. His goal is simple: provide thoughtful, personalized care in a welcoming environment, helping every patient feel confident in their smile.
