About Cedar Dental Care
At Cedar Dental Care, we combine modern technology with compassionate care to create a dental home for families in Fremont, Castro Valley, and the greater Bay Area. Castro Valley traces its origins to the original land grant, Rancho San Lorenzo, which was given to Don Guillermo Castro. As a prominent landowner, Don Guillermo Castro’s gambling habit and resulting gambling debts forced him to sell portions of his land to pay gambling debts, significantly shaping the area’s land ownership and development, including the surrounding Palomares Canyons. From preventive checkups to advanced restorations, our team is dedicated to helping patients enjoy a lifetime of healthy, confident smiles. We are also committed to serving the local business community in Castro Valley.
Quality Professionals
Our dentists and staff are committed to ongoing education, ensuring patients receive the most effective and safe treatments. We believe in building long-term relationships with our patients, offering trust and transparency at every step.
Experienced Staff
From your first walk through our doors to your regular checkups, our team provides warm, personalized care. We treat every patient like family and work hard to create a stress-free environment.

They made the process easy and clear to understand with respect to the work being done and out-of-pocket payment. Jocelyn made sure I was comfortable while taking my X-rays. Dr. Sinha took the time to review the X-rays and explain the next steps, focusing on helping me feel better.

FAST AND FRIENDLY SERVICE Elena Baruah2025-06-06Trustindex verifies that the original source of the review is Google. Dr Preeti Kumar was very helpful. She agreed to come and see me on Saturday and she helped me with my tooth pain. I texted her at night time after my visit because my pain was not subsiding. She ordered a different prescription and my meds were ready for me to pick up on Sunday morning. She then texted me a few times over the next few days to check how I was feeling and ensure I made a progress towards recovery. Reception ladies were super helpful as well.
