Check out what some of our happy patients are saying about us:

Vanda B. from Mission Viejo, CA (Source: Yelp)


Dr Lydon is a very dedicated and results oriented dentist.  She is gentle and definitely pain free. I now have set of beautiful teeth, no not false teeth.  Recently an ear specialist determined that I had a dental problem which was causing my severe earaches. Dr Lydon took the bull by the horn and worked fearlessly on my teeth and night guard resulting in no more earaches OR headaches. Her office is beautiful and state of art. Very calming and a pleasure to visit. Another point is that she rarely refers you to others for she confident in her abilities and proves it by her work.  I strongly recommend Dr Lydon .

Michelle S. from Mission Viejo, CA (Source: Yelp)


Dr. Lydon is a wonderful caring dentist that does her own cleanings and works with a realistic attitude about what she does.  She will suggest things that could be done to improve your dental health but understands that your finances and/or attitudes may affect what you want or can do.  She is not pushy about you spending more.  She has patients that travel from other counties to see her.  She has set  hours but has been known to come in at other times to help patients out. She truly cares about her patients’ lives.  She asks about the family and even brought me a souvenir from a recent trip. Her staff is courteous and helpful.  A great change after trying many, many dentists and finally almost giving up.

A+++ Dr. Lydon is the best, most trustworthy dentist I’ve ever had. And she’s got personality! I’ve been to her for all the routine stuff: dental cleanings, metal filling replacements, cavity fills, etc. She hooked me up with a night guard that is so comfortable and effective that I can’t imagine sleeping without it. I live in LA but happily drive to Irvine for her expertise. The staff is professional, skilled, and kind. Highly recommend this practice!

Pam S. from Newport Beach, CA (Source: Yelp)


I have been a patient for over 3 years and could not be more satisfied.  I have never had my teeth cleaned and not ached for 24-48 hours…until Dr. Lydon.  I love her staff and her. Finally, if you haven’t seen her new office yet, it is so fresh and inviting, I love it.

My husband and I have been patients of Dr. Lydon for about 8 years. She is friendly, takes her time and explains our dental needs. The office and staff are top notch.

Ara K. from Los Angeles, CA (Source: Yelp)


My wife and I recently became patients of Dr. Lydon. No other dentist we’ve ever had gives as much attention and time to each patient; she really wants to get to know you and – more importantly – your mouth. While most dentist I’ve had are running a mill to make money… she is on the quality not quantity side of the business. Her staff is also very welcoming, professional, and capable.

Timothy S. from San Francisco, CA (Source: Yelp)


Dr. Lydon has made a big difference for me.  When I first came into the office, I wasn’t sure how it was going to go.  I have neglected my teeth for quite a while because of bad experiences with other Dentist.
What I didn’t expect was mapped out plan of what we could accomplish. Dr. Lydon reviewed all options and let me choose what I thought we could accomplish with proper guidance.  Everyone that works with Dr. Lydon has a very caring attitude.  It’s Lydon family dentistry, because you feel like family when you go there.  I will recommend Dr. Lydon to anyone that is looking for the right place to go.

Casey P. from Huntington Beach, CA (Source: Yelp)


I’ve been going to Dr. Lydon for about 5 or 6 years and she’s great. She’s got a very nice little office and the staff is super friendly. I’ve never had to wait in the waiting room there, I show up and they’re ready to go.  I usually go on my lunch break and am out with time to spare.  

I recommend Dr. Lydon to anyone who is looking for quality dental work and a positive experience when going to the dentist.

Bobby X. from Irvine, CA (Source: Yelp)


It’s been a little over three years since I’ve been here and I have to say that Dr. Lydon is great. She’s very personable and funny, and my time here is always enjoyable, as far as dentist visits go. All in all great place to get your work done quickly and done right. The staff are also great, kind, and awesome. You won’t be disappointed.

Anisa N. from San Clemente, CA (Source: Yelp)


(…)I have been seeing Dr. Lydon for about 15 years now, and can easily say she is the best dentist I have ever been to. She is the one who actually cleans your teeth every time (not a random hygienist like some offices), so you always know exactly what you are going to get. She knows her patients and cares about each one of them. She is funny and personable and I look forward to seeing her. Who looks forward to seeing their dentist?!? Give her a try and I promise you won’t be disappointed. And if you refer your friends, you know they are going to get great care, and you will always get a little treat, too. It’s all part of how well she takes care of her patients. She’s the best!

Tina M. from Mission Viejo, CA (Source: Yelp)


A friend referred me to Dr. Lydon since I needed a new dentist. I went in for a teeth cleaning and it was the best cleaning I’ve had! She does the first cleaning to get to know you. Dr. Lydon is so thorough and knowledgeable. She noticed I had a small crack in my back molar from grinding my teeth during the night. She suggested a mouth guard to stop further damage in my molar that can lead to a crown or root canal. I’ve seen her several times since then because she wants to make sure the mouth guard fits correctly.

Her staff is very helpful and friendly. The office is very modern and tech savvy.  I love that Dr. Lydon’s chairs also have a massage option built in!

After almost a year long search (…) getting different information from each dentist , I went back to Dr. Lydon . She knew what I needed to have done and never wavered or try to sell me on things I didn’t need as others did . The other thing that was great is that she never overbooks , I never had to wait or watch a dentist jump from room to room with multiple patients .
Now that the work has been done I couldn’t be happier with the outcome , she did an amazing job .
Her and her staff are accommodating , friendly and very good at what they do .

Caroline A. from Irvine, CA (Source: Yelp)


(…)Dr. Lydon is by far the best dentist I have ever visited; she won’t tip toe around your teeth issues to let you hear what you want, she’ll tell you the truth because she wants the best for you. Anytime she does work on my teeth she thoroughly explains everything she is doing and why. I get a hug from her every time I come in because she truly treats me, and every patient like her dear friend. I highly recommend her to anyone getting anything from a consultation to major dental work!

Shani M. from Laguna Niguel, CA (Source: Yelp)


I have been going to Dr. Lydon since Jan. 2012 when she changed my smile.  I am very happy with her and know that she really cares for my teeth.  She is proud of her work and makes sure that you maintain your teeth while under her care.
I have since referred many others.  My mother is having Dr. Lydon add 7 new implants and she is also very happy with the outcome so far.

Kimberly Suttles Braithwaite (Source: Facebook)


Dr. Lyndon cares about her patients’ smiles more than anyone. I have never liked going to the dentist until I met her.

Kathryn C. from Newport Beach, CA (Source: Yelp)


Dr. Lydon is always a joy to schedule an appointment with. She is not only a great dentist but a great person. She has done every one of my cleaning herself and takes pride in making your teeth as perfect as they can be. When I have had to come in for longer appointments to get other work done, she has let me stream Netflix to pass the time on her account using Netflix glasses. Her patient chairs are also massage chairs.  No better way to pass the time! Her receptionists are also great!

Barry M. from Newport Beach, CA (Source: Yelp)



ncredible Dentist! I highly recommend Dr. Lydon. The best thing about Dr. Lydon is that you will have a quick, pain free experience.She really knows to get that anesthesia dialed in so you don’t get any painful zingers. I’ve never had any “problem” procedures or infections  either.Her staff is friendly and professional. Dr. Lydon is funny too!:)

Ken E. from Huntington Beach, CA (Source: Yelp)


Dr. Lydon is 5 stars as a dentist and 5 stars for humor…she’s fun to go visit. Who can say they look forward to seeing their dentist? But even more importantly she does great work and is an excellent dentist. We were referred to her by a family member who swears by her.  After we had our first visit over 5 years ago we knew we found the right dentist for our family.  Our kids love her too.  She takes her time with you and gets to know you as a person with genuine interest. We never feel rushed and not once have we ever waited to be seen.  When we show up for our appts. We are immediately taken back to start.  We live in HB and its well worth the drive to Irvine to see her.  Her staff is top notch and always friendly and easy to work with.  Finally, she has all the latest technology in her office to make our experience easy.  Thanks Dr. Lydon.

I’ve been going to Dr. Lydon for about 10 years. She is an excellent and most caring dentist. The staff are friendly and put you at ease. The facility is clean and comfortable (even has vibrating massage chairs). She explains procedures, follows up in personally in calling patients after hours to confirm their comfort. Though professional, her demeanor is down to earth, funny and comforting. She is very approachable and honest. She takes pride in her detailed work while showing great consideration and care of her patients. I have no reservations in recommending Dr. Lydon for any dental work.

She’s the best ever! She makes me smile, makes my smile beautiful and she loves what she does. Five stars all around!!! ⭐️⭐️⭐️⭐️⭐️

Brian F. Monarch Bay, CA (Source: Yelp)


(…)During my first visit, Dr. Lydon found a few areas of my mouth that could use some more attention. She was open and honest about what my options were and offered guidance on how treatment today could prevent issues down the line. Her approach to addressing potential issues early on was very different from past dentists who wanted to wait and see if the problem got worse.

I opted for some deep cleaning, which took place over two additional visits and was done by Carmela, the dental hygienist. Carmela was just as professional and knowledgeable as Dr. Lydon and made the entire process a breeze.

Every encounter I’ve had with Dr. Lydon and her team has been a positive one and I look forward to being a patient for many years to come.

Amy D. from Laguna Niguel, CA (Source: Yelp)


I have been a patient for over 15 years. Dr Lydon is an exceptional dentist. She takes the extra time to make sure your treatment is the best it can be!
You will never need to look for another dentist after seeing her. Her staff is kind and efficient.
I would give 10 stars if allowed.

Christian F. from Irvine, CA (Source: Yelp)


Absolutely worth a 5 star rating. Dr. Lydon is as personable as she is talented with a drill. I came in with some minor sensitivity and to my surprise I needed some real work done after not seeing a dentist for almost 6 years. Dr. Lydon got to work two weeks later and put my mind to ease. I will say I was a bit nervous preceding that first session. The dentist can be a severely unpleasant experience, but this wasn’t. At all! I never felt even the slightest amount of pain during the procedure and for the amount of work I needed it was over pretty quick. I feel comfortable here now, like I can trust these people. From the office managers welcoming personality to Dr. Lydon’s sass I honestly felt like I could just come and hang out here. At a dentist’s office! Needless to say it is an overwhelmingly great experience for a visit to the dentist. Your cheating yourself if you are seeing anyone else.

Patty Z. from Costa Mesa, CA (Source: Yelp)


Dr. Lydon is an amazing dentist!   I have gone to her for over 10 years and referred many friends and colleagues. Dr. Lydon makes the dental experience fun and she keeps me from being too nervous with her funny stories.  She has a really friendly staff and office hours to accommodate my crazy schedule. She puts patient care first and it shows. She has state of the art equipment and is always advancing her practice. I would strongly encourage you to start with Dr. Lydon so you can see how amazing it can be to have a great dentist.

Sean G. from Kenner, LA (Source: Yelp)


Until Dr Lydon, I have always hated going to the dentist.  It was something I avoided for years, so there was a lot of fixing for her to do!  Dr Lydon makes every visit super enjoyable and always strives for perfection when it comes to my teeth.  It’s actually hard to believe she was able to get anything done with me laughing at all her stories!

Susan A. from Irvine, CA (Source: Yelp)


Dr. Lydon and her staff are the best!  I’ve been a patient of hers for 10 years.  She has expertise as well as truly caring for her patients.  She goes above and beyond, in calling after hours to confirm the procedure done previously is still comfortable and there are no complications.  The facility is clean and the chairs even have massage capability!  Dr. Lydon, with her entertaining stories takes the sting out of anxiety that most people have in getting dental work.   She is very thorough in explaining what needs to be done and answers any questions.  The staff are friendly and put patients at ease.  I highly recommend Dr. Lydon.

Michael C. from Corona, CA (Source: Yelp)


Exceeded my expectations!!!
Dr. Lydon and her team made me feel comfortable from day one.  Exceptional care was taken during my visit, very transparent, providing all options and direction regarding my treatment.  Dr. Lydon truly cares about the service she provides and it shows!
I would highly recommend Dr. Lydon and her team to anyone!!!

I had my share of procedures with Dr. Lydon (several cavities and a root canal) and she’s done amazing work. Plenty of anesthesia, and she’s a riot. Highly recommended.

Melanie C. from Tustin, CA (Source: Yelp)


Best dentist ever! Doctor Lydon makes you feel comfortable and really has your best interest in mind. My father had a problem with trusting dentists but she changed his mind. I had to get a crown for one of the front teeth and was very nervous whether it would look natural or not. She promised I would look better than ever with her skillful technique. She kept her promise and no one can tell I have a crown now 😀 so glad my family found her!

Heidi S. from Santa Ana, CA (Source: Yelp)


Having had a lot of dental work done in the past, I generally hate visiting the dentist. But Dr Lydon is the best dentist I have ever had! She is down-to-earth, accommodating, and really cares about making you feel comfortable in the dentist chair. I needed an implant (among other things) and it’s been a year since she did it and I’ve had no issues with it. I referred my sister and she also had an implant done there with no problems. Highly recommend!!!!

Dr. Lydon is the best dentist I have ever had. She is extremely skilled and does a perfect job. On top of it all, she is a pleasure to spend time with. I can say that I actually look forward to going to the dentist.

Her staff are excellent as well. They are friendly and welcoming and extremely professional(…).

Michelle V. from San Francisco, CA (Source: Yelp)


Dr. Lydon is exceptional. She is the best dentist I have ever had. She wants nothing but the best case for her patients, and that is evident from the moment you walk in the door. I have never had a dentist that cared enough to call me the next day after an appointment, to check in and genuinely see how I was feeling. That is the type of person and professional that Dr. Lydon is.

Monica B. from Santa Ana, CA (Source: Yelp)


Dr Lydon has been my dentist for about 8 months, and has helped me with several issues. Not only did she convince me to get a mouth guard for night time, but she’s done two cleanings (herself), and several fillings. When I was worried about a front tooth turning grey, she had me come in on a day she normally doesn’t work and managed to do the work by herself with out an assistant. She always takes her time and explains things well. Her staff is very knowledgeable about insurance issues. They are very upfront about costs. This was the first time I’d had dental insurance in a long while, so it was great to find a wonderful dentist to help me catch up with my dental care that had been put off.
