We are a family-owned and operated dentistry serving Contra Costa County and the surrounding area. We offer a comprehensive range of treatments to help our patients improve the long-term health and cosmetic appearance of their teeth and gums. No matter how often you brush your teeth or floss, home care just isn't enough.

Bacteria collects in hard to reach places and may cause cavities and discoloration to develop over time. Thus, regular check-ups are highly recommended to ensure a healthy smile. From subtle changes to major repairs, we offer treatments for chipped, discolored, and oddly shaped teeth to improve your smile.

We are a family-owned and operated dentistry serving Contra Costa County and the surrounding area. We offer a comprehensive range of treatments to help our patients improve the long-term health and cosmetic appearance of their teeth and gums. Our mission is to transform oral health through customized, quality dental care for people of all ages and dental needs.
Dr. Tatyana Yashchuk has been a dentist for over 20 years. She received her Doctor of Dental Surgery (D.D.S.) degree from First Leningrad Medical Institute in Saint Petersburg, Russia. In the United States, prior to receiving her Dental Board of California License in 2001, she received dental training from two prestigious schools, University of South California in Los Angeles and the University of the Pacific in San Francisco.
Routine dental cleanings and check-ups are important to maintaining good oral hygiene. Professional cleaning will remove plaque which, if not properly removed, can overtime cause more serious and costly conditions. Dental exams, x-rays, and other diagnostic procedures are important in evaluating your oral health and hygiene.
A dental crown may be needed for a variety of reasons: to protect a weak or broken tooth, to hold a dental bridge in place, or to cover up a decayed tooth, severely discolored tooth, or dental implant. Porcelain-fused-to-metal (PFM) and zirconia crowns provide the best natural color match than any other types of crowns.
If you are having an emergency, please call us directly at (925) 246-3187, instead of making an appointment online. This will ensure proper response time. Toothache has a wide variety of causes, ranging from tooth decay (cavities) to trauma to the tooth from injury or teeth grinding. Thus, toothache should always be considered an emergency.

I have been going to Golden State Dentistry for the last 5 years. They are honest and very professional. Prices are average for the area. Definitely recommend them to public.

Dr. Yashchuk is excellent. She provides great dental care. I’ve had fillings, crowns, whitenings, cleanings, and now starting Invisalign. I have been a patient for over a year now and during the quarantine. The office is very clean and diligent.

I made an appointment over the phone after my original appointment for cleaning was cancelled back in May - I was told that they only do cleaning on Saturdays so I had to sacrifice my weekend plans in order to make it.
When I showed up for my scheduled appointment today, they told me they couldn't see me because the appointment wasn't on the books!
I've been a client at Golden State dentistry for a long time but not coming back after such lack of care and service

For the first time in my life I feel like I can completely trust my dentist. My husband and I have been going to Dr. Tatyana for more than 2 years.
No matter what need to be done I can sit back and relax. No joke! Going to the dentist appointment have always been my worst nightmare.. not anymore.
Dr. Tatyana is gentle, caring and super professional. We feel blessed we finally found her.

Excellent!
They treat teeth of any complexity! Where other dentist recommends tooth extraction, they save and cure your tooth.
Very friendly staff and excellent service.
