About Smiletheory

We're here for you

Smiletheory was started with the belief that going to the dentist can be something you could look forward to.


Dr. Vinni K. Singh

Dr. Vinni K. Singh thinks dentistry has a bad reputation. She has made it her life’s mission to change the way people feel about dentists. From authentic conversations to genuine concern for your health, Smiletheory patients feel like they’re part of our family. It’s what sets us apart from every other dental office. 

Dr. Vinni K. Singh is a native of Portland, Oregon. Growing up, she always knew she wanted a healthcare career so she could help people live healthier lives. Eventually, she realized that good oral health was the gateway to good overall health. She moved to California to pursue her degree at the University of the Pacific in Stockton. After graduating with honors, she attended their world-renowned dental school in San Francisco. She completed her postgraduate surgical training from the prestigious Loma Linda University School of Dentistry and is an active member of several study clubs in the Bay Area, staying abreast of the latest techniques and advancements. 

Dr. Singh continually commits herself to furthering her knowledge and education so she can deliver the highest quality dentistry to her patients. She is trained in CEREC same-day crowns, is an Invisalign teeth-straightening aligner provider, and is a member of the highly regarded Kois Center in Seattle. She has expertise in occlusal disease and misalignment, helping patients who struggle with TMJ pain and bite issues. She can treat both children and the elderly and those who struggle with a wide-range of dental issues. 

Dr. Singh is fluent in English, Spanish, Punjabi, and Hindi and welcomes patients of diverse backgrounds to her practice. Patients commend her on her compassionate bedside manner and gentle touch. Dr. Singh welcomes new patients and their families to Smiletheory for a truly personal dental experience.

Dr. Mohita Sinha

As a compassionate and self motivated dentist, Dr. Sinha believes in educating all her patients and helping them make the right treatment choices for themselves. 

Not many dentists in the Bay Area can say that they have multiple professional and graduate degrees, but Dr. Sinha is an exception. After completing her bachelors and masters degrees from India’s most prestigious dental school, she moved to the United States and completed her fellowship from UCSF. She was honored to have her graduate research published by the renowned American Journal of Orthodontics and Dentofacial Orthopedics. She continued her dental education and earned her Doctor of Dental Surgery degree from Loma Linda University School of Dentistry, where she was inducted into the elite Omicron Kappa Upsilon national dental honor society. Outside of dentistry, she loves to explore different cuisines with her husband and watch movies from the DC and Marvel universe.
