    I came here in hopes to find someone more proactive on my dental care due to cancer treatments and…read moremeds that affect my teeth. Nancy in the front office took amazing care of me, treated me with empathy and urgency. I ended up needing treatment from an endodontist and they coordinated my apts and communicated so well. They really took care of me and relieved so much stress for me, as if I'm not already going through so much. Dr. Hong explained to me in terms i could understand and gave recommendations and a plan i was comfortable and confident with. I had many concerns and they just took care of it. Talk about SERVICE!!! They definitely went way above and way beyond!! They made me feel so comfortable and confident. It's hard finding good people and people you can trust these days, but you can trust Dr. Hong and Nancy here.

    I just moved to the area recently and was looking for a new dentist. I am so grateful that I found…read moreDr. Hong and team! From my initial phone call with Nancy to meeting everyone in the office in person, the experience has been incredible. Everyone was so kind, caring, and attentive. Dr. Hong is incredibly knowledgeable and made me feel informed and empowered about my dental health. He thoroughly explained the current condition of my gums and teeth and clearly laid out next steps to improve my oral health going forward. By far the best dentist office experience I've had!

The pain management experience is what impressed me the most because I get really nervous about how much pain is coming my way. Dr Mehru Bhatia extracted my wisdom tooth with minimal pain and it took 3 minutes to extract. I had such a great experience that I now bring my entire family there for all things dental. I highly recommend Mehru Bhatia at My Smile Dental Care!

    My husband had a root canal done a year ago with Dr. Bhatia. The cap fell off 4 months later. We…read morecalled and they said they would fix it. He had it fixed and 2 months later it fell again. I asked for a refund and they were not inclined as "this happens". We went to a new dentist that fixed it and noted that it would have to be redone. After multiple attempts we have not been able to get the money refunded or the claim removed off our insurance to have the work redone by our new dentist. Root canals are intended to last at least 7 years for insurance to cover them again and now we are stuck paying out of pocket because Bhatia will not release the claim. The tooth now has to be extracted. After 3 visits to Bhatia is just didn't make sense to continue to go back to "fix it" and now my husband has to loose this tooth.

    I have been with Dr. Chang for over 20 years, and I can honestly say she is one of the most caring…read moreand trustworthy dentist I have ever met. What I appreciate most is that she never over sell any treatments. She always presents all of the available treatment options and takes the time to explain the pros and cons of each one in a way that is easy to understand. I never feel pressured into making a decision and I always feel informed and confident about my treatment choices. Every visit feels personal. She listens carefully, answer questions patiently, and genuinely cares about her patient's well-being. It's clear that her priority is what is best for the patient, not what is most profitable. After 20 years, I still trust her completely with my dental care. She's honest, knowledgeable, compassionate, and truly puts her patients first.

The reason I kept going back to his office was bc I always had the same dental hygienist so it felt familiar whenever I went every six months, but I'm Happy to report that I've found my new fave dentist office! Christine and her team are all so nice, and it doesn't seem like a rotating door here - the staff here are consistent and welcoming! Christine takes her time to listen to your concerns and what's key here is that they're always on time. I've never had to wait in the waiting room a long time unlike some other dentist offices (looking at you Anaheim hills dental group.. )! Also never felt pressured to do any treatments I didn't feel ready for. They are pretty kid/toddler friendly as well. My daughter's first dental experience was here and it went great; she has no fears about the dentist and loves the little treasure box she can pick from after her check up.
