    About 18+ years ago I experienced a very traumatic dental encounter going in to get some minor dental work. I had an impacted wisdom tooth that hadn't come through the gun line and was infected due to the impaction. Without getting into the major details of it all, I ended up leaving that dental office in an ambulance loosing God only knows how much blood and 3 liters of blood at the hospital. That dentist severed my artery in my mouth and almost died from that experience. Needless to say the details and trauma have stayed with me over the years. Fast forward to 2023, I'm a bit older and have learned to adapt to a small degree to maintain the health of my mouth. I was referred to St John Dental in Azusa and couldn't be more happy. The Dr is straight forward about his work and gets it done. He has lovely staff and clearly isn't doing to make as much money as possible like some in the industry. I was able to endure some work like a champ and credit his staff as well as the dentist for assisting me through that process. Not only did they do a great job on my work but are helping me work through, what is a stain of insecurity and PTSD from that past experience. I would absolutely encourage you if you're reading this and need dental work, to put your trust in this office as they're going to make sure you're comfortable and in the know about what they're doing. Thank you Dr. and staff for your great work compassion. I highly recommend this office for your future dental needs. Blessings friends!

    I'm happy that I found this place. It's clean and there all Super friendly. They went out of there way for my schedule twice. On my first visit my appointment was at 430 and I was in so much pain. I needed a root canal and a two teeth pulled. The staff and Dr. Hana stayed till 930pm working on me, I was glad to get all my work done right there and there. Dr. Hana is a straight forward kind of guy and honest, so I just want to say Thank you!!!

    Before the procedure

    I travel for work. I'm in a different city every week. I came in for a consult with x-ray on Wednesday, it only cost $50. The hygienist recommended a visit with Dr. Hana the next day. I have no insurance, and Dr. Hana was able to fill cavities on three of my teeth as well as do a root canal all on the same day. I will come back at the end of my work season to have him finish repairing my front teeth. The price was very reasonable for paying cash with no insurance. Dr. was very attentive to my needs and made sure I was comfortable and felt well informed throughout the procedure. Thank you for making this a productive and beneficial visit, Dr. Hana.

    Sr who has teeth cleaned every six months. Dislike full mouth X-rays unless a problem or suspect of something. X-rays on rare occasion ok if I have a problem but all the xraying frequently not necessary. How much for cleaning?

    It depends on your oral exam too

    Do they do tooth-colored fillings?

    Yes we do

    Do they do gold or silver filling options?

    No not anymore

    I cannot recommend Dr. Cho and the team at Root Endo Vision enough…read more Before my appointment, I was honestly terrified. I had heard so many horror stories about root canals that I was expecting the worst. I went in feeling extremely nervous and anxious. But from the moment I arrived, the entire staff was so kind, comforting, and reassuring. Every single person there made me feel supported and kept reminding me that everything was going to be okay. Dr. Cho was absolutely amazing. He was so gentle, calm, and precise throughout the entire procedure. I kept waiting for the pain everyone talks about... and it never happened. I truly didn't feel anything. I was shocked at how smooth and easy the whole process was. He made something I was so scared of feel effortless. His assistant was wonderful as well. They worked together so seamlessly and professionally, making sure I was comfortable every step of the way. You can really tell this team cares about their patients and takes pride in making the experience as gentle and stress-free as possible. I walked in terrified and walked out feeling so relieved and grateful. I honestly can't believe how easy the whole experience was compared to everything I had heard before. If you ever need a root canal, do yourself a favor and go see Dr. Cho at Root Endo Vision. I would absolutely trust them again and will definitely refer my family and friends here. Thank you for turning something I feared so much into such a positive experience!

Because they aren't a general "do-it-all" dental office, the level of expertise and efficiency is on another level.

She's super bubbly and doesn't make you feel pressured to make a decision on the spot. Dental hygienist that worked on me was Angie, very sweet, light hands and if I felt sensitivity she stopped.

Yvette always made sure I was comfortable, offered me water and headphones to relax, very sweet and easy to talk to.

Both are remarkably thorough, meticulous, and uncompromising in their approach--never taking shortcuts when it comes to quality or patient comfort.
