Monica M Trieu, DDS

I have been going to Dr Trieu for several years now and she is by far the best dentist I have ever had.
I went a 10+ year stretch without seeing any dentist because I had a fear of dentists and I am so happy that I was referred to Dr. Trieu by a coworker. She was very receptive of my fears and I finally felt like I found a dentist that cared. She constantly asks if I’m in any pain or discomfort and helps to create a calm and relaxing atmosphere.
The quality of the work is excellent. I’ve had a crown put in that looks perfect, feels and functions like a normal tooth. The cleanings are excellent and it’s amazing that she does them herself as opposed to having an assistant do the polishing work. You can really sense that Dr. Trieu takes great pride in her work.
I feel like everything is explained to me by Linda at the front desk before I go in and always get a reminder call 2 days prior to my appointment. As I mentioned I did not take particularly good care of my teeth, so I needed some deep cleanings, a crown, and some very ancient sliver filings replaced. Dr. Trieu created a treatment plan to get the work done over several sessions and I feel like my teeth are finally healthy.
I would recommend Dr Trieu to anyone seeking a high quality dentist who cares about her work and especially for anyone who is hesitant/​fearful of a return to the dentist.

My boyfriend and I have been going to Dr. Trieu for a year, it is not a long time compared to those who have been her patients since they were a child, but it is enough to conclude that Dr. Trieu is the best dentist I have ever seen!
The first time we came here for cleaning and x-​ray exam, Dr. Trieu explained the details of our teeth problem one teeth by one teeth (they name the teeth in numbers), with a clear price marked in each bar, and most importantly, there is no pressure at all for our choice, she even emphasized that she is only doing her job as a dentist for suggestion and advice. So I am very shocked when I saw previous reviews saying that she intended to earn profit from exaggerating the dental problem. I have done 4 sessions of deep cleaning, 2 fillings and 2 months of bleaching, and since the first time I started to FALL ASLEEP during the process. She provides the blanket, pillow and even handset which make you very relaxed, and she will take care of every little issue of my teeth smoothly and gently. Our dental health is in poor condition before, but after this year, she teaches us how to care for our teeth in daily activities, now they are very healthy and beautiful!
I love everyone in this office: Joelisa, the assistant, is super professional, nice and thoughtful, put me at ease; Linda in the front desk, she is soooooooo nice and very elegant and always reminds me of the appointments two days before the day!
I will leave Irvine in a few months, but I will definitely miss these three people forever, thank you Dr. Trieu, thank you Joelisa and Linda!!!

I’ve been seeing Dr. Trieu for almost two years now. It’s been outstanding experience for me and I’m shocked to see few 1-​star reviews here. Let’s see.
Coming from a different country I never had a permanent dentist before, so I can’t compare fairly. However I had some teeth work done here and there and I must agree with some other reviewers that initial costs of this office are high. But that is only because how pedantic and professional Dr. Trieu is with x-​rays and all the preparation and planning that goes into each client treatment schedule. I wouldn’t recommend her for a one time job, especially because there are probably many places that will give a discount (and will downplay the upfront scope of work) for new customers.
Where Dr. Trieu truly shines is long-​term relationship and costs planning. After few initial visits, we discussed and came up with my individualized treatment plan for the following year, taking into account my insurance annual limitations and prioritizing work that will provide higher ROI. This entire time Dr. Trieu has been extremely transparent about what’s coming. Estimated costs are provided by front desk assistant before AND after every visit (for next scheduled appointment), so I absolutely have no idea how some reviewers got «cheated». They probably lied about their insurance or didn’t have it at all.
Few words about assistants. Linda (front desk assistant) is just brilliant. When she took this job about a year ago, I couldn’t believe she is permanent — the level of service and care she provides is so high, I thought she is some superstar from elite golf club helping out a friend temporary. Jolissa (dentist assistant) is 5^th or the 6^th person in this position I’ve met. Dr. Trieu has very high quality standards for herself and her assistants, so I pity those girls who went through cold iron and blood trial (from patients bleeding gums) just to be replaced with another candidate. Jolissa appears to be very talented to stay along.
I don’t think there is any other dentist in OC that will be so paranoid about health and well-​being. Besides healthy teeth and gums I’ve got a lot of great advice (and some prescriptions!) from Dr. Trieu for my skin, quality of life, mental health. I actually enjoy my time spent in her cabinet. Never thought I would say that about dentist.

I’ve been going to Dr. Trieu for a few years now. She is honestly the most thorough dentist I’ve ever been to. When I moved out of the area for a while and had the chance to experience other dentists, I realized just how much more attention Dr. Trieu gives you by actually doing the cleanings herself. And she cares about you!
I don’t understand all the negative reviews for her. A majority of them seem to deal with billing/​insurance issues. Like I guess it is kinda the office’s responsibility to tell you, but if you’re a grown ass adult you should be able to know if your Dr. Trieu takes your insurance or not. Or you know you could just ask to clarify.
I honestly don’t know if Dr. Trieu is more expensive than normal. I just know that she’s taken great care of my teeth and I go out of my way to see her when I can.

Saw Dr. Trieu once 3 or so years ago while looking for a new dentist near work. One, she’s expensive and was out of network. Two, she seemed to think I needed all sorts of work that no dentist before or after have never said I needed. Dr. Trieu said I had all sorts of decay and gum issues, especially around my wisdom teeth. Even showed me some sort of digital image that show my teeth all black in those areas. According to her I needed several thousand dollars of dental work. Subsequent dentists have also shown me images of my teeth, and there is zero black areas.

Dr. Trieu is a great dentist. She does your cleaning, not an assistant. She has small hands (a plus for a dentist!) and has a great sense of humor. She cares about your needs. My husband and I moved out of state and made appointments to see her during a return visit. That’s how great she is!

Dr. Trieu is a true gem! She is honest, professional, and pleasant. Every time I am seen in her office I feel very at ease and comfortable, the staff is super friendly and organized they go the extra mile in finding appointments that fit my husband and my schedule and always remind us of our appointments before hand. I have to say that my favorite part is dealing with Dr. Trieu, she does all the cleanings herself (which I value a lot) and she does an immaculate job. I really cannot complain about anything because I had to learn the hard way that not all dentist are created equal. My husband went to see another dentist that was more convenient at the time for him to get a cavity fixed for cheaper, well they did a horrible job but thankfully we had Dr. Trieu to fix it. So those who complain about her prices being high, I say you get what you pay for. She is fair in her pricing because she only provides the very best service and gives you all her time and attention.

So, I’m one of those EXTREMELY a freaked out people when it comes to the dentist. I’m talking, Valium for a cleaning just to get me through the door.
I’ve NEVER found a dentist that puts me at ease, nor have i found a dentist that I felt genuinely cared about my concerns etc.
That is, until I met this ANGEL! She’s the first doctor to ever put me at ease, to the point where I DIDNT need a Valium just to walk through her door.
I love the fact that Dr. Trieu spends her time with each patient, rather than passing the jobs on to assistants etc.
She does VERY thorough exams, and takes all the time necessary to go over any questions I may have.
Linda, who works the phones and front office, is AWESOME. She is very thorough when going over pricing etc, and is very calming from the moment she says «hi»…Linda was a huge help when it came to calming my nerves and making my visits go well. She’s so warm and welcoming.
Dr trieu is by far the one of best Dentists ever.

this dentist charges bloody hell fees, not just on your visit, but also bill you half a year later. I just took simple x-​ray in her clinical for one teeth, charged me a couple hundred bucks on the day, then later billed me additional hundred bucks again. What the hell, are you money sucker? You should have told me how much for the simple x-​ray film, and I would have just left right away. I wanted to give ZERO star rating! not sure if it’s possible. So poor fellows, never ever go to see Monica, she will suck all your savings out of your bank account.

Where do I even start. Dr Trieu is such an amazing dentist. She takes the time to really clean your teeth. Appointments usually last about 1 hour for cleaning. I really like that about her. It shows that she really cares for her patients and isn’t in a rush. It seems like she doesn’t care about the money since her schedule isn’t overbooked with patients. She still drives her 14 year old Toyota! She’s so humble and a genuinely nice person.
Definitely recommend her! She’s the best!

I’ve been going to Dr. Trieu for a few years now. Her practice is the best. I’ve never had to wait more than 5 minutes. She prides herself on respecting your time by not keeping you waiting, but she does expect that your on time a well. I’ve never had any issues with her work, although my dental needs have mostly been just cleanings and a few fillings. She takes her time with you and never seems rushed. As another reviewer mentioned, she does her own cleanings! Most other dentists use hygienists.
Overall it’s always a great experience and I highly recommend her.

I NEVER thought going to the dentist would actually be a pleasure or something I look forward to… until meeting Mrs. Monica Trieu, DDS.

Absolutely positively hands down fantastic. The very best dentist you can find in Orange County. Some memorable moments:
–Offered to grind down a tooth that was bothering her, I told her I did not have the budget for it this month. Not only did she offer to bill me next month, she fixed another chip on the front tooth as a bonus.
–She takes her time spring cleaning your teeth, this is not an in and out place.
–She made my husband floss and care about his teeth.
–I can actually wear the night guard she made for me, which is a big deal I have spent $$$$ out of pocket for worthless contraptions before.
–she never tries to sell you anything, she is honest and tells it as it is, respectfully yes and with a quirky sense of humor.
Dr Trieu is a perfectionist and I will have to look far and wide for someone as good as she is. I am going to miss our conversations.
Sara, her dental assistant, is competent, calm and discreet. Maria her office manager is friendly and efficient.

Hubby and I have been going to Dr. Trieu for almost… 8 years, now! She is a dentist who takes pride in her work, taking the time to do each cleaning herself. She also does a whole-​mouth evaluation during each visit, which I don’t remember my dentists doing the past. She tells me which areas I seem to be skimping on and such. (I always get an «excellent» rating on my attitude and a «good» rating on my flossing, which is silly since she knows that I’m terrible at flossing. I should really start flossing…)
I normally don’t like to leave reviews for businesses while I’m still an ongoing customer, but in this instance I’m happy to do so. Her (as so many of her patients put it) quirky personality leaves me laughing after each visit. She’s pretty funny. :)

I have been a patient of Dr. Trieu for 10 years and that is for good reason. She is the best at what she does. I feel like she takes care of my teeth as she does her own. Dr. Trieu deliberately sees fewer patients than other dentists because she does not want to compromise speed for quality care. She also has a very data oriented approach as she keeps detailed notes about the condition of my teeth for better follow up and tracking over time. Every experience I have had has been great and she has the same enthusiasm for her work as someone just starting in the field.
Not only is she a great dentist but she also come to know my whole family and what we have been doing in our lives. She also knows that I don’t like ice cold water sprayed on my gums due to sensitivity and not to tilt the chair back too far. She is always conscious of my preferences. She has a great sense of humor and yes is a bit quirky but all the more reason to love her as a real person.
I’m about to relocate out of Orange County and dread having to find another dentist in my new city who can measure up to Dr. Trieu.

Dr. Trieu is one of the best dentists I ever had. I usually hate going to the dentist before I started going to Dr. Trieu. Dr. Trieu is very thorough with her work; she will take her time to make sure your teeth is clean. Usually you have a hygienist doing your teeth cleaning appointment, but when you go to Dr. Trieu, she does it herself. Also, when she measures your pockets, it does not hurt. When my previous doctors measure my pockets, they weren’t very gentle. Also, Dr. Trieu and her staff are very friendly. Dr. Trieu actually treats you more of a friend than as a patient. Doctors don’t usually don’t care about their patients and it’s always about the «Get in, get out» mentality. So it’s nice to have a doctor that actually cares.
Dr. Trieu is usually booked. So if you want to have work done by Dr. Trieu, make sure that you make an appointment.

I am a person who did not regularly enjoy going to the dentist, but am prone to getting cavaties. I have had bad experiences with other dentists who gave painful numbing injections which have made me dislike the dentist more.
I recently started going to see Dr. Trieu after a long time friend gave me her reference.
She is fantastic, a little quirky, but she is the only dentist I know that will fill your fillings and also take the time to personally clean your teeth (because she wants to know your teeth the best that she can in order to help you the most.) She gives the most painless injections for fillings! I had ten fillings done (yes, it was a lot, some were redos due to poor fillings from a previous dentist) in the last year and each time was relatively painless and as enjoyable as a filling can be.
When you meet Dr. Trieu, you will realize that she is not a doctor trying to charge you for ridiculous things and her equipment is not 30 years old like some other user commented ! The lady doesn’t even wear makeup or drive some flashy car like your average dentist ! She thoroughly explains to you why she recommends that you have a certain procedure such as deep cleaning and lets you. know the charge before you agree to it. She gives you all options when it comes to what will be best for your teeth.
She is overall a fantastic dentist and once you have been her patient, you will not search for another doctor because she is simply the best.
Yes, go make an appointment today !!! You will not be disappointed !!!

I moved from Santa Barbara to Orange County and Dr. Trieu was recommend to me by a friend. As most people I dread dentist appts, however I have to say my experience with Dr. Trieu and her staff was my best ever.
I started with a yearly cleaning and was very surprised. Normally my dentist does a 45min cleaning and he is done, Dr Trieu divided my appt’s into 2 one Hr sessions. She did an absolutely amazing, painless job. She was very careful and made sure I was comfortable the whole time. She even called me from her house later that night to see how I was doing.
She is very personable, and actually takes an interest in you past your teeth. She always remembers things I have talked with her about at pervious appointments. It’s nice to feel like our not just another patient being ushered through.
I would definitely recommend Dr. Trieu to anyone.

5 stars for a dentist might seem crazy, but the only thing that is crazy is how awesome Dr. Trieu is.
i, like everyone else, was terrified of going to the dentist. it had the same feeling as going to the mechanic, or the dmv, or the post office. i absolutely hated it, and was always broke and/​or in pain afterwards. i discovered the amazing Unilocal reviews on Dr. Trieu and decided it was time to make taking care of my teeth a positive thing.
long story short-​i have since moved to LA and i STILL go all the way to Irvine for my appointments, thats how great she is.
these 5 star reviews are no joke. if you want a dentist that actually cares about her patients, and has a great sense of humor-​go see Dr. Trieu.
it was my birthday yesterday and she called to wish me a happy birthday as well as see how i was doing from my last appointment a few days prior. that right there is amazing. i have FRIENDS who didnt even call to say happy birthday.

My wife found Dr. Monica Trieu on Unilocal and has raved about her ever since. She talked about how much better Dr. Trieu is than her previous dentists. After moving to Orange County, I decided to see Dr. Trieu too.
I’ve seen Dr. Trieu for a checkup, cleaning, and two replacement fillings. She is extremely thorough and explains everything! She did the teeth cleaning herself and was very gentle. She is the best at giving shots… so good that I didn’t feel anything! Not even a pinch! I don’t know if it’s her technique or maybe the numbing gel she uses, but the shots didn’t hurt at all.
Dr. Trieu, Vicky and June are all really nice! If you’re looking for a new dentist in Orange County, then I recommend making an appointment to see her.
