Great dr. I've been seeing him for years and often refer people to him. My family sees him also…read more Very personable and listens to you.

This is the guy you don't hope to see....but if you must...this is the guy you will WANT to see…read more The shy and pleasant, highly skilled Dr. Jong is an oral surgeon. Our visits required skill at pulling particularly malignant teeth, bone grafting, and preparing the mouth for implants. A referral to Dr. Jong came with high praise from our own wonderful dentists, Dr. Tomazin and Dr. Kim located in Riverside. They are part of a special circle of dentists in our area who are holistic practitioners. My husband has been a patient of Dr. Jong's for at least a couple of years. Mr. B has the gift of particularly bad genes when it comes to teeth. In each instance, we chose to replace those rascals with an implant. Ripping them out all at once was not in the cards, they chose to demand their own attention one...at...a...friggin...time. So having a trustworthy dentist for each these instances was essential. And now, most recently, it was my turn to visit the good doc after a back molar with an old root canal decided to crack and become infected. I was informed these are the kind of teeth that no dentist wants to address unless they are specialized. Enter Dr. Jong. His spacious, impeccable office has a calming vibe and his staff are delightful. More importantly, he pays close attention to make sure that you will feel no pain during the process. Unlike the commercials I see these days that promise you brand new implants in one, yes ONE day (not sure how that goes), this process promises to be a test in patience. Mine required multiple visits starting with x-rays from 3 specialists before they decided this tooth was a real loser, followed by subsequent visits for the extraction and bone grafting, another for stitch removal, then waiting 4-5 months for the graft to take and the gum to heal. Then Dr. Jong does the actual implant process. The last tah dah is my personal dentist who performs the final crown fitting and installation. So there you have it. A glorious way for me to support the dental community and keep enjoying eating steak, not pablum, in my old age. Bottom line. Dr. Jong is excellent and comes highly recommended by me and my dentist.

I was treated by Dr. Stockdale for almost 2.5 years and got my braces off less than six months ago…read more I'm so glad that I found the right orthodontist! It's hard to pick just any orthodontist because there are so many and you are making a big investment, time and money both. I'm so glad I found Dr. Stockdale at Dental Associates of Corona. I went from big gaps to a perfect smile, something that I never thought I'd have. As long as you kept up with your appointments and do your regular cleanings with your dentist, you will see amazing results. Dr. Stockdale's office is a well-oiled machine. I would have to say that in every visit, I was seen within 5 minutes. If I had to wait, it was because others were late to their appointments, but you're in and out within 15-20 minutes depending on what needs to be done. They keep it moving. The staff is nice, fun, and caring. I just found out that he has an office in Rancho Cucamonga, less than 2 miles away from my home!!! Boy, I wish I had known this a while back. I moved to Rancho in 2012 and have been commuting to Corona for 1.5 years (and coming from work in Claremont too!) Oh well, I don't regret it one bit. Thanks for the life-changing experience.

At first, I was hesitant to get braces as an adult. Dr. Stockdale has done a great job and I LOVED…read moremy results!! Both my kids had braces placed by Dr. Stockdale, the results were excellent!! Their smiles show it in their high school senior yearbook and grad photos. I highly recommend Dr. Stockdale if you want braces as adult, teenager or child.

I don't even live in the area anymore, and I still drive back because this office is that good. The…read moredentist, hygienist, and entire staff are incredibly smart, knowledgeable, and genuinely focused on your wellbeing--not upselling you like the big corporate dental chains. You never get that "buying a car" feeling here. Just honest care, fair pricing, and people who actually advocate for you. They've even gone to bat with my insurance when needed. I've never had a cleaning as thorough and comfortable as the ones I get here. It's on a completely different level, and it's the reason I'll never switch dentists. The office itself is modern, comfortable, and equipped with high‑tech tools that make the whole experience smooth and stress‑free. Nathan at the front desk is amazing--professional, friendly, and someone I genuinely consider a friend. He makes every visit easy and welcoming. I'm truly grateful for this team. In an area full of dentists trying to sell you something, this office stands out for doing the exact opposite: providing exceptional care you can trust.

Is Ben a minute so i wanted to update my review. This time I had a deep clean as well as address…read moresome old fillings that needed attention. They are very accommodating when it comes to scheduling and i was able to get in for the cleaning and then scheduled for the filling repair. Let me just say that Dr Kim and his team are extremely efficient and work incredibly well in synchrony. Laying there in the chair you can see them work together and I'm truly impressed with the work. I highly recommend Dr Kim and his team.
