Through her work at Los Altos Family Smiles, Dr. Vaswani is honored to help her hometown residents achieve healthy and happy smiles.

After years of happy cleanings, orthodontic work, and early removal of wisdom teeth, she graduated from her pediatric dental office to the scary world of adult dentistry. She, unfortunately, learned the hard way that all those blissful years of not flossing with brackets and wires lead to cavities.

With the help of a wonderful and gentle general dentist, she overcame her fear of needles and dental procedures, experiences that played a significant role in shaping her professional life.

Education has always shaped Dr. Vaswani’s path. She began her studies down the street at Oak Elementary, Blach Intermediate, and Mountain View High School before graduating from Harker in 2004.

Since returning to California, she has been on local adventures checking out outdoor trails, new restaurants, and bars with a mean cocktail.  In her spare time, she enjoys music, traveling, reading, binge-watching shows on Netflix, and spending time with her husband, Sagar. 

Dr. Vaswani loves reconnecting with families she knew as a child and thrives on welcoming new families to the practice. She is currently accepting new patients. Booking a visit to meet with her takes just a few moments online or by phone.
