    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.

She's nice and pleasant, making going to the dentist easy. She makes it as fun as it can be. It is the dentist after all. I would see the only approve Mensch I'd like to see. Is there not as fast as I'd like appointments take a while.

    I wanted to give this dentistry zero review!!!…read more Here is the story! I made a loan for a one-tooth implant starting from 10/26/2021. An assistant manager kind of woman at the front desk showed me the one-implant original price ($6,658.00), but she gave me the final total cost of the loan $5,811.20 because she said in-house dentistry discount. She made me an electrical sign for the original price of $ 6,658.00. And later she made me sign again for $ 5,811.20. At that time, she told me to rest assured that this price difference would change on the system. And she said the total bill was $ 5,811.20. After that, I received my first bill from the Smile Generation that this dentistry has. The invoice showed the original price of $ 6,658.00 instead of $ 5,811.20. I visited the dentist's office and told her about it. And she promised me a refund of $846.80 ($6,658.00-$5,811.20) A few days later, when I logged in to my Smile Generation account, I was able to confirm the refund, but the refund amount was -$ 651.25 instead of the full difference of -$ 846.80. I again visited the dentist 3 times and complained about it. Every time I visited, she promised to refund the difference of -$195.55 ($ 846.80-$651.25). However, I couldn't confirm the refund after a month, so I visited the dentist again. She again said she would refund it. But nothing happened. I went to the dentist at least 5 to 6 times and made a complaint. This was wasting my time. It was already 3 months passed. Never refund. In the end, I talked to the office manager on 1/26/2022. He confirmed the final difference of $195.55 in the system in front of me and my wife. He promised he would process the refund.  but he said it would take a month. (I doubt why it took so long. It's impossible.) because the first refund ($651.25) I could confirm was just a few days... but he said a month. I tolerated and agreed with what he said. I waited and waited. However, even after a month of 2/26/2022, the refund of $ 195.55 had not been confirmed yet. It was already 4 months passed. I decided to contact the Dental Board of California.  Thomas Trevor is the main dentist and CEO of dentistry. He has the responsibility.  I emailed him directly. I told him that I assumed that his staff (manager and the assistant kind of woman are cheating patients like this and they use the difference of the amount for their own money) I contacted lawyers and they gave me several advice. I also decided to give a bad rate about this dentistry.  This is CEO's management issue. He needs to control his office manager and his assistant. They are very fishy. They are not sincere. I emailed this dentist 3 times but never replied. Very irresponsible after all... My last day of the dental appointment was 2/12/2022.  At the time, money -$195.55 was not refunded. The Dental Board of CA (DBC) emailed me back and care about this matter. They mailed me in the middle of March 2022. Waited and waited... I finally confirmed -$195.55 in my smile generation account on 4/1/2022. It took more than 5 months. What is this!!! I am sure that they never refunded me if I did not contact DBC. Also, I asked for my teeth cleaned. They showed me the total price of $1381.00 with so many service items. It's so expensive just asking for only regular cleaning. I didn't need to have such a deep cleaning. I asked the fishy manager that I just wanted to do the regular teeth cleaning. Then he said they wouldn't give me the cleaning. I needed to do a $1380.00 cleaning. I am sure this dentist, especially the tricky and swindler manager there... ripped patients off! Please be careful all!

My appointment was this morning at 10:00 am. I was extremely nervous as I always am with the dentist. I have been going to my dentist for 25 plus years and felt very comfortable with him and his staff. Since I was about 5 I've had dental work done. I had a horrible fear of the dentist so I wasn't ready to have this extraction done by a total stranger lol. Well I'm here to brag on this Dr. he was all the things I was told and more. His staff was amazing the office was so clean and the view from where I was sitting in the procedure room , was so beautiful and tranquil!! I didnt feel a thing and he was finished in no time! He explained each procedure every step of the way! I HIGHLY recommend him! I will be returning for inplants soon. They even put a blanket over me so sweet. MAY GOD BLESS YOU Dr. Phuong G. Huynh and your staff for many years doing this and helping so many and making it affordabl! ‍His name is pronounced Dr. Win. if your wondering.

I would happily go through child birth three times over before going through that again..... After my third trip to urgent care, multiple misdiagnosis and two rounds of antibiotic's, they finally told me to contact my doctor or dentist. I was COMPLETELY clueless as to who I needed to call. At that point, I'd missed a week of work (fortunately, I had plenty of PTO to spare) and I was basically hysterical. I contacted my dentist first thing Monday morning and they referred me to an oral surgeon. Naturally, the oral surgeon accepted my dental insurance but not my medical insurance (they weren't sure if it would cross over to medical). I still made the apt for the next day but started looking for someone who accepted both insurances. I am SO grateful I found this office. Everyone there was incredibly kind and they fit me in that morning. The doctor and was amazing. The woman at the front desk was a saint for getting me in so quickly (kicking myself that I don't remember her name.) I have nothing but praise to sing for this office! I am incredibly grateful for them.

    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.
