I'm missing one or more teeth

Not only can missing teeth make you feel self conscious, but they can also lead to the deterioration of the bone structure in your jaw. A dental implant will improve the appearance of your smile and prevent bone loss.

Start Smiling



Dr. Jeff Yoshihara was born and raised in Union City, CA. He chose to stay local and attended UC Berkeley for his undergraduate education, earning a degree in Integrative Biology before moving down to Southern California to attend the UCLA School of Dentistry. After graduating, Dr. Jeff decided to move back to the Bay Area and has been practicing as a general dentist ever since. 

Dr. Jeff believes that patient education, understanding, and comfort are just as important as the quality of dentistry being provided. He takes the time to discuss and review all treatment options with his patients, working collaboratively to design a treatment plan that best meets each individual patient's needs.  

While he is a perfectionist (an ideal quality to have in a dentist), Dr. Jeff is also very relaxed and can usually be found smiling or heard laughing around the office. His hobbies include weight lifting, photography, fashion, and napping.
