Signature Dental

Dr. Yang has been our dentist for a couple of years and we are very happy with her! Our daughter is now a patient as well. I have not experienced any of the negative problems some of the patients have stated. Dr. Yang is personable and knowledgable. A definite plus is that appointments are schedule so I do not have to wait! I highly recommend Dr. Yang.

Dr. Mimi Yang is AWESOME! Not only is she a GREAT dentist, but so personable and fun to talk with as well. She provides a relaxing atmosphere and she better NEVER leave Brea!

Dr. Yang could be a great dentist technique-​wise, but she tries to milk you for every little procedure that may need to be done. Granted, I came to her after not going to the dentist for 2 years, but I did not have any problems or pain with my teeth when I came to her, but somehow, she «found» 6 cavities and recommended a re-​do of a root canal + a crown for a front tooth that I got a root canal on a decade ago. The total cost of all of this? About $ 5,000−6,000, or about $ 2,000 out of pocket with my PPO insurance. Do I look like a walking sack of money? Silly me, I listened to her and «filled in» the 6 «cavities» which could have just been minor stains that had no affect on the integrity of my teeth and went to her recommended orthodontist in Fullerton to re-​do my root canal. She probably gets some sort of kick-​back from recommending patients to him for root canals and unnecessary procedures.
Post root-​canal re-​do, I went back to her to get the temporary filling filled and a post put in in preparation for a crown, but when I saw the ludicrous out of pocket cost for the crown and fear of shaving off my entire front tooth, I wanted a second opinion from another dentist. Turns out there is a simple procedure that can bleach the inside of your tooth to remove the stain that comes with a root canal and is much more conservative in saving your original tooth, and at a fraction of the cost and pain a crown would have caused. Looks like someone needs to go back to dental school, or just wants yo money in exchange for your tooth.
Be forewarned, or be prepared to be upcharged, pay out of pocket costs at the office + get a surprise bill in the mail for some extra fees or procedures that they tacked on without your consent as well. Look elsewhere for a dentist, trust me.

Dr. Yang is wonderful and I’m extremely grateful to have found her practice. I’ve had countless negative experiences with past Dentists that have left me with a SEVERE anxiety towards all dental procedures! I called Signature Dental/​Brea with a broken tooth and they were able to see me the same day! I needed Oral Surgery to remove the tooth :-(and the Oral Surgeon was flexible to have it done as soon as possible!
A major PLUS about Dr. Yang is that she presented and explained all of my options and I NEVER felt pressured. In the past, I’ve been pressured to purchase add-​ons or expensive procedures that just jacked up the bill… Not here!
Dr. Yang has wonderful bedside manner that helps with High Anxiety patients like myself. She also prescribed medication to ease my nerves during surgery. Overall, the procedure didn’t even hurt!
Seriously, for the first time I’m happy to say I know a GREAT dentist. My teeth have a chance now.
I highly recommend this office to everyone who has Dental Anxiety or who has just had bad experiences in the past. 6 Stars!

My girlfriend had a toothache so I had to find a dentist – my last dentist is in Newport Beach and that is too far from where we now live (Brea) so I choose Signature Dental. We used a coupon for the initial exam and Dr. Yang evaluated her tooth and discovered that was a wisdom tooth and then told us that she is unable to extract wisdom teeth in her office. She didn’t charge us for the visit (and the 10 min she spent with us) which was expected because of the coupon. She did recommend 2 oral surgeons, one in her building and one in Tustin – and she added that the one in Tustin was «better» than the one in her building. So, we took our little referral paper to Tustin the next night and 2 wisdom teeth extracted was a total of $ 1280… being put under local was a part of that cost – but I am guessing that referral paper I gave the receptionist was a «kick-​back» to Dr. Yang for the business she sent over to Dr. Lee. Not confirmed, but I am pretty sure that is the way it works.
Fast forward to my own cleaning – I have Delta Dental HMO and I was charged a $ 35 «co-​pay» and up-​sold for some anti-​bacterial rinse – AKA, $ 55 for some mouthwash – stupid me. Upon thinking about it the next morning, I called Delta Dental and they said I should not have had any co-​pay (the up-​sale was on me)…so I called the office and the receptionist told me that the charge was for photos (not given the option to NOT have this done – and told it was a co-​pay, not a charge for a service that is not covered) and $ 5 copay – when she gave me the code for the fee – it is actually «observation only – no other services performed» but I did get my teeth cleaned so I didn’t understand that one. Some might say «why bicker over $ 5″ – but it was obvious that they are just finding things to charge for if you have HMO insurance – I guess the HMO doesn’t pay enough.
My girlfriend (no insurance) had not been to the dentist in a few years, and since her mouth had healed from the extractions, I made an appointment for her right after mine. For her, the x-​rays, photos and Dr. consult was $ 212. Dr. Yang recommended deep cleaning ($ 740), seven fillings (only 2 for new cavities – the other 5 are «just looking a little old and should be redone») ($ 1873) for a total of $ 2613. I seriously laughed out loud. I know why people don’t go to the dentist if they don’t have insurance. Needless to say, I said «thanks but no thanks» and promptly called Delta Dental to ask about individual plans, signed her up and paid for a year of Delta Dental HMO ($ 101 for the whole year) and called the dentist back. Of course, the insurance is accepted but suddenly they couldn’t see her for 22 days (if we were paying cash, they had an appointment any day we wanted within the next 10 days), and, because her consult, x-​rays and photos were paid cash, she would need to have that all re-​done so that the insurance could be billed. As if I didn’t have enough red flags, I cancelled all of it, headed to Unilocal for help and called a different dentist.
So, although Dr. Yang was pleasant and her assistant was nice, unless you have a lot of money to burn, pass on Signature Dentist and listen to Unilocalers for advice on Brea dentists.

Today was my second visit to this dental office. I had a cleaning a d filling. I am so thankful I found this dentist! She is kind, quick and thorough. For years I avoided going to the dentist due to my extreme fear; however, she put me completely at ease. I am actually looking forward to my next visit in 6 months. Additionally, I am thankful that I no longer have this fear. Lastly, the staff are very sweet ladies.

Dr Yang was wonderful. I got cleaning done with some fillings. She was gentle and friendly. The staff was nice. Def recommend to my friends.

Picked this dentist as our primary on my work’s dental HMO based on Unilocal reviews.
My wife went for the first time today for an evaluation, X-​rays, etc for a new patient. After the evaluation, Dr Yang told my wife to come back for a cleaning and to fill a minor cavity the next day.
The office staff then gave her a proposed treatment plan and pressured her to pay before she left. Luckily she decided to come home to review the plan against our insurance benefits:
For the eval, cleaning, and resin composite filling, our HMO insurance lists a total cost of $ 35 ($ 5 first visit, $ 5 second visit, $ 25 for the 2-​surface resin filling).
The price the staff at Dr Yang’s office told us was our after-​insurance cost was $ 337 — an 863% markup on our actual patient cost of $ 35. This is accomplished with a variety of dishonest billing: charging $ 30 for «mouth photographs» on top of the covered x-​Rays, adding a $ 110 for unspecified «other medicaments» to a prophylaxis cleaning that is covered at $ 0, billing $ 89 for the $ 25 filling «due to new ADA coding not listed on our insurance benefits», and finally charging $ 98 for anesthesia which is, once again, covered at $ 0 by our insurance.
When I called to ask if I had made a mistake in my comparison, the front office woman Lena went into full on rude, defense, salesman mode, telling me I can’t read my own benefits, telling me I don’t know the difference between resin and amalgam fillings, and so on…
I wish I’d seen David B’s review from 3÷14÷14 before picking this dentist, since it sounds like a common occurrence here… My guess is they try this technique and hope that the number of people who trust them and pay their dishonest 863% markup will make up for the number of people like us who catch their fraud and wisely walk away. Pretty cynical business model, but oh well.
«Too long, didn’t read» summary: They’ll rip you off and lie to your face while they do it. Look elsewhere.

I’ve been in to see Dr. Yang twice now (once for consultation/​cleaning and once to replace a filling). The office is clean, well designed and filled with current equipment — which is really nice. But the biggest positive is Dr. Yang. She has a wonderful chair-​side manner, doesn’t push or try to talk you into procedures and is very friendly and happy! During my procedure, she kept checking on me, making sure I was comfortable and not in any pain and we were done FAST! I’m so happy to have found her!

I heard of this dental office thru Unilocal so I gave it a try. My experience was not so good. Although im sure the dentist is great (according to other helpers), but the front desk girl really killed my experience. I really think the receptionist is a reflection of the dentist. I feel sorry for the dentist… totally lost my business because of the rude front desk girl. I really felt it was personal.
Such a long story n I dont know how to make short. But the bottom line is I will never come back to this place because of the bad service. She’s so rude. Although the whole time she was calm but the things that she says to me and her gestures and her service was very frustrating and totally not accommodating at all. U know how they said the silent ones are the most dangerous ones? She is like that!
I felt she was totally personal w me even though I was trying so hard to remain calm n nice. But at the end, I was so pissed off that I walked away not seeing the dentist at all.

We came to Signature Dental after being cheated by another Dentist. I was so happy to find such a clean professional office with a Dr who could treat my children.
I see all of the five star reviews here and I’m guessing they are written by patient’s either with PPO insurance or who pay obscene amounts out of pocket. My insurance is an HMO and I believe Signature Dental is operating as a bait-​and-​switch for people like myself. They were willing to sign up with my insurance but as soon as I got into the building they did nothing but try to get more money out of me.
A small example… Dr Yang convinced my wife to spend extra for a «Deep Cleaning». When she came back for her next cleaning she was told… «Now that you’ve had a Deep Cleaning you have to follow-​up with a Periodontal Cleaning» (also not covered by our insurance). My wife told them she was not made aware of this up front and left frustrated. I called to explain my wife just wanted the regular cleaning as covered by our insurance. They refused to schedule the appointment. Not long after we received a letter stating they were ending their relationship with my insurance. Well, I guess that’s good riddance for both of us because we will never go back to Signature Dental anyway.
I believe Dr Yang is quite intelligent and deliberately insulates herself behind pushy coercive admin staff to do the dirty work of pulling more money out of patient’s pockets.
Just my opinions. Make of it what you will.

Dr. Mimi Yang purchased the dental practice here about 18 months ago. She is an improvement! Still as clean and professional as before, but Dr. Yang provides more personal attention, and she is so smart. If I am going to drop a dime on my grill, I am glad it’s with Dr. Yang.

So I will start off by saying that I have been TERRIFIED of the dentist since I was a little girl. I never had a great experience with them until I came across Dr. Mimi Yang!
At first, my nerves were getting the best of me but Dr. Yang talked to me and calmed me down. She was so gentle in every way, explained everything she was doing, and her suggestions. I felt like she genuinely cared! For the first time in YEARS I am fine with going to the dentist without having a minor panic attack in the process. (lol)
All in all, her staff is amazing from the receptionist to her assistant they all make a great team! Dr. Mimi Yang is and will always continue to be my dentist! You’ve gained a loyal patient! :)
Thank you all so much!

PART 2 — Another great experience!
So I had a follow-​up appointment to get my teeth deep cleaned with Dr. Mimi. I hate the idea of getting shots in my mouth to get numbed up. I was pleasantly surprised that it did not hurt at all and the procedure was done quicker than I thought it would be. Dr. Mimi and her tech Erica both worked as a team and provided excellent care. I also received a follow-​up call from Dr. Mimi to see how I was doing. WHAT? This never happens anymore. Great job.
You will not be disappointed.
PART 1 —
I am a real skeptic when it comes to seeing a dentist. Too many bad experiences until last week.
My daughter and I went to see Dr. Mimi Yang and we were both very impressed. From the beginning working with Lena in the office to Erica the dental assistant to Dr. Yang our visit was a very positive one. Dr. Yang took the time to explain the outcome of the digital x-​rays that were taken and gave suggestions on continued care. They were not pushy at all and had our best interest at heart. Not many dental practices have the bed side manner that they do.
Signature Dental is a very professional, positive and caring dental office that my teenage daughter and I would highly recommend.

I have been going to Signature Dental for the last 3 years and the service has always been great, but I just went in for my cleaning yesterday and I noticed that Dr. Mimi Yang took over the practice.
All I can say is that I absolutely love this dentist, not only was she funny, but she had a great personality, she always made sure I was ok and was very professional as she performed the deep cleaning.
In all my years of going to a dentist, I have to say that is has been the most enjoyable and fun experience.
The staff there is great as well. Do yourself a favor and go see this place its awesome! I’m never leaving this place.

Does anyone know where Dr. Agneau went after he left Signature Dental. If you know then please get back to me at
thank you

Good efficient service. Dr Yang was gentle and took care of my cleaning in a professional manner. I thought she was thorough and I got a good cleaning job. Some dentists that I visited gave teeth cleaning like as if I was brushing teeth myself, but with Dr Yang, the cleaning is a professional job. Would definitely return for my yearly cleaning. The office staff was friendly and the equipment was new (I can’t stand going to offices with old rusty old chairs, but Signature’s got shiny new chairs and sinks.) overall a good experience.

Dr. Mimi Yang is an exceptional dentist!
I found her a couple years ago through 1−800-DENTIST and was amazed with her gentle manner when numbing an area for fillings as well as her expertise, experience, and the state-​of-​the-​art technology… I just saw her last month as she recently took over Signature Dental and she found 4 cavities… I have not had cavities in decades, but I just had a baby 2 years ago, so apparently these cavities were due to my pregnancy (the baby got the calcium!)…
I was a bit nervous, but Dr. Mimi never ceases to impress.
Not only was I out of there in less than 1.5 hours, but I barely felt a thing!!!
Wow! That was awesome!
She also took great care to ensure my fillings were smoothed out nicely
I thought I was going to have a lot of pain, but I was worried for nothing.
Dr. Mimi is one of those health providers that you develop a long-​time relationship with… because you never want to leave!
Many thanks to Dr. Mimi and her wonderful staff!

In January of 2010 I went in for a cleaning and told them I was on a tight schedule and that I had a specific time I would need to leave their office by. I asked if they had time to complete the cleaning, they said they could. I was then swept off to x-​rays and then was visited by a female dentist who explained nearly $ 7000 worth of work I could expect to need done. Then out of time, I did not receive the cleaning I scheduled for. I went to the front desk and was charged $ 237.00 for x-​rays and an exam I did not schedule. I left with my teeth not cleaned, late to my next appointment and very upset. I went to another dentist and had the x-​ray fowarded, they were not able to use them. After a cleaning, a complete new set of x-​rays and a second opinion my future dental needs were under $ 2000. With the new information from the second opinion I put a stop payment on my check and later phoned the dental office to complain about my experience. I was told I would be held responsible to pay the amount of $ 237.00 for the x-​rays & exam (that I never asked for). Then about 2 weeks later they sent my file to collections and I now have it on my credit report as an unpaid medical. Their customer service was pitiful to say the least. I am a business owner and specialize in customer service, I’d be out of business if I handled my clients their way. IN MY OPINION, FIND ANOTHER DENTIST!!!
I will do my best to spread the word to my clients and friends who live in Brea.

Awful! I went in for a cleaning, she was wonderful. Never saw her again. They said I needed alot of work, so I got it done. They took forever each time I went in, the impressions didn’t fit, and had to be redone requiring more visits. They didn’t have the proper glue to put my bridge in, so I sat and waited for 40 minutes while someone went to get it from their Anaheim Hills office! They were short a dental assistant one day so the office manager stepped in to help. You can’t make this craziness up! Couldn’t get out of there fast enough! Run!!!
