Unprofessional, unclean, I saw dirty tools a dirty mirror that was used in my mouth. Nurses didn't properly set up. My dentist removing my wisdom teeth was aggressive, unintelligible, at times seemed confused. The tools did not look sanitary! Midway through my removal, I had to ask them to stop. The nurse pulling my cheek open kept getting yelled at by the dentist cause she wasn't doing her job right. Wich I could feel it and hear it. I asked them to stop cause I was beginning to panic. I asked for vaseline and she told me I'd get it when I was done... .okay? .... Wich by the end

This dentist office is the worst! I scheduled a wisdom tooth extraction in December 2020 and the dental surgeon only comes once a month so I had to wait 2 months until February 2021. I called to confirm prior to my appointment only to find out they "rescheduled for me" to March without my knowledge. The fact that they did this without my consent was unprofessional, had I not called I wouldn't of even known they rescheduled my appointment. When I was leaving, the receptionist and a dental assistant were gossiping about patients which again makes the office unprofessional.

I got my 2 of wisdom teeth removed a few years ago and had the worst experience ever. They caused permanent damage giving me TMJ because they used a block way too large for my mouth. At one point they even began drilling into the wrong tooth. My stitches fell out after 2 days, so my gums did not heal correctly. They became infected since they never even gave me anything to clean them. The whole time I was awake and just felt chunks of my teeth going down my throat. The experience I had here left me too terrified to get my remaining 2 wisdom teeth removed.

I have been coming here for a couple of years now and love it. The doctors are amazing they never do anything that's absolutely not needed like many other dental offices. The specialist is amazing! The office staff always pleasant and helpful especially Maria. I hate any dental work but FDG makes the visit a little less stressful. Take care of your teeth and if your in the Ontario area give this office the opportunity to service your needs you will not be sorry.

Not the best dentist office they barely clean your teeth if you go in close to closing time and Lunch is more important to them than a patent in pain but the dr's do good work that's the only reason they get 3 stars

I have severe anxiety when it comes to the dentist. The combination of the pain and noise freaks me out. I want to say that they did an excellent job. I didn't feel anything NEAR the pain I anticipated. I couldn't believe a root canal could be so painless.

I would never go to this place ever again.

This was one of the most convenient dental surgeons I could go to with MEDI-CAL/DENTI-CAL.

I was told by my normal dentist to get a CT scan of my mouth regarding my wisdom teeth and the positioning of what he could see.

After finding a dentist who had the CT scan available, and paying 275$ for the scan. That dentist had explained to me what I would need done in my surgery for extraction. Regarding the placement of my lower jaw nerve and how I would need to be put under anesthesia.

I then took my dental CT scan to this FIRST DENTAL GROUP when i arrived

Let me begin by saying that I've become accustomed to sub-standard health care. Ever since my family bought insurance through the ACA Marketplace, we've either experienced incompetent providers, long waits, or no providers at all. I do appreciate having health care, but subsidies certainly come with drawbacks. So, when I was referred to this office for a desperately needed root canal, I was nervous. When I told my previous dentist about the pain I was feeling, he told me to wait at least six months for the tissue to rest before he would take a second look at the tooth. So, I logically

Yaojen is a very awesome dentist. It was my first time to be there, I had a big cavity and some other cavities. I did teeth filling and wisdom teeth extraction. It was so fast and efficient, when I was doing the teeth, I didn't feel any hurt, maybe a little, I think it's normal. I have to say he is very experienced, I will come few months later to do my other teeth fillings. (So sad, I have a lot of teeth problems i know, I will stop to eat sugar things)
I would definitely recommend him to be your dentist.

Been going here for years. Very caring Dentists and Assistants. I lost my fear of going to the dentist here.
I recommend First Dental and I will not be going anywhere else unless they close.

Ok, let's be real! You can't give a dentist office 5stars period. They cause you pain and their all in your mouth, oddly, pulling this way and thata way and that drilling noise is just eerie (I can't stand to hear it, do I go in with headphones)!

But with the that negatively, I still line the work they is done. The staff is really nice, they know my name and face as I walk, their calling me by name, before I sign in. The doctors (father and son) are both graduates of USC! That alone is great and they really know they stuff.
Office waiting room, no big deal to it. However it is

If you need a professional and genuine dentist, 1st dental is the BEST! I actually went for a second opinion to 1st Dental because I had been diagnosed with multiple cavities and crowns by a previous dentist. When I first arrived, I was pleasantly greeted and received timely, caring service. I met the dentist, Dr. Chang and explained I was there for a second opinion. Dr. Chang did a thorough, yet very gentle exam and x-rays and was able to explain to me the needed treatment. It was FAR less than the previous dentist! Dr. Chang was extremely professional, kind and educated. He helped me understand
