I don’t think i could have a better experience. I had a tooth emergency, was a new patient, and they got me in the very next day. Not only did they get me in, they were able to fix a filling, make me a crown, and deep clean my gums all in the same day. The entire staff was beyond helpful and friendly. I felt like they genuinely had my best interest at heart. I am extremely grateful I got my teeth fixed that day, I was for sure I’d have to wait 2 weeks to have a crown made. The dentist was so caring too. I highly recommend this place. I also want to give their teeth whitening 5 stars, I was so impressed! Good job guys, thank you for the great experience and making me feel like a priority!

Dr.Mahallati has been my dentist for over 11 years. The staff is amazing. Never a dull moment. They always make it fun with their smiles and caring personalities. I drive all the way from Norwalk, totally worth the drive. I always share with friends and family about his practice. He takes his time with each patient. Explains all necessary treatment needed. You will never feel forced but I highly recommend getting your treatment done ASAP before it gets worse.
I’m very satisfied with my tooth implant which completely looks natural. I’ve also had braces, root canals and fillings with Dr.Mahallati. We all have our own favorite assistant, but I have two. Bonnie and Holly have been there for many years. They have a great relationship with most patients including myself. They have two hygienists, both are sweet and gentle. Front office staff is very professional. Give them a try, you won’t be disappointed!
Thank you Dr.Mahallati and staff for my beautiful smile!

(…) I have worked in dental for 7 years and I can say without a doubt Dr. Mahallati has something really special going on here. He has a gentle hand and very informative. His work wIll speak for itself. Gina and Sergio in the front office are great. They worked with me in navigating through the obstacle course that is dental insurance. Finally, Joel, my dental assistant, was great from the moment he introduced himself. Service, customer service, and pricing are all there. Thank you, everyone, at Bay Dental!

Been a patient for the past 19 years. I’ve had 2 dental emergencies in that time. They were able to see me even near closing time. Dr Mahaltti and his staff stayed late during my ordeal. I will be a patient for years to come. Thanks!

5 stars. Best dentist ever!!! I’ve been coming here for 7 plus years and I wouldn’t go anywhere else. Dr. Mahallati is a genius at his craft. He’s always making sure everything is okay and you are comfortable before starting any procedures. The staff here (Gina, Sergio, Bonnie, Holly & Jo) are so friendly and very professional (…).

I have been coming here for a few years now. Greatly appreciate the caring Dr Mahalati. I like the wide range of services they offer from General dentistry to cosmetics. The staff is very nice, professional and flexible to accommodate.

Office billing had contacted my insurance prior to my arrival and was able to explain my benefits and provide accurate pricing information, which is really important when weighing financial decisions. Dr. Mahallati was very kind and personable. He helped me relax before beginning. All the staff members I met were very friendly, caring, and helpful. They made sure I understood treatment and that I was not in pain.

(…) Our loyalty as clients is exceeded only by the loyalty of Dr. Mahallati’s staff, many of whom have stuck around forever – surely the best endorsement of their boss and his practice. Dr. Shahin himself always apologizes just before sticking in the numbing needle, the gentleman that he is. Hygienist Brandi has that reassuring, quietly confident air of competence and still cleans and examines our teeth as thoroughly and as patiently as the first time. Bonnie continues to excel as the best “dental impressionist” west of the Mississippi, minimizing gagging when taking impressions. Holly’s calm demeanor, presence, and quiet wisdom would suggest she still has her wisdom teeth. Sergio knows instantly what buttons to push (on the computer, not people) to call up our accounts. Gina at the front desk is never short of a welcoming smile, even when on a long hold by the insurance company. Joel has recently joined the team and has already left a good impression of his courtesy and professionalism (…).

My 83-year-old mom was in CA for a short visit and had a major dental emergency. Dr. Mahallati took my mom through a 3-hour procedure with the utmost expertise, patience, and care… We are extremely grateful to him and his amazing staff.
I was referred to Dr. Mahallati when my previous dentist insisted on pulling out a tooth… thankfully I got a 2nd opinion from Dr. Mahallati; he saved my tooth & I still have the same tooth and crown, 10 years later! Dr. Mahallati has also been my 16-year-old son’s Dentist and Orthodontist & we have great results. I can say without any hesitation that Dr. Mahallati is a very caring, knowledgeable and an exceptional Doctor.

I have been coming to this dentist for 20 plus years and I have always had an awesome experience. Dr. Mahallati and the staff are extremely experienced and professional. I have had plenty of other dentists growing up, but once my mom found this place we never searched for another dentist again. A++ Work. If I could give more stars, I would! Thank you as always Bay Dental!

Ann M. from Santa Ana, CA (Source: Yelp)


My husband and I have been patients at Bay Dental for years and couldn’t be happier with them! It’s nice to see the same faces that make you feel right at home. We’ve had a lot of dental work at this office and the process of understanding the cost and treatment is easy because of the professional, friendly team.  I can’t imagine anyone having any issues here at all. Some people can’t take the truth that their teeth need extensive work and are just hard to please no matter how much you cater to them. We’ve already recommended some friends here and they are pleased with the entire office as well. Thanks, Bay Dental Team!

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


Dr Mahallati has been my dentist for 18 years and has been my children’s dentist since they were little. He does excellent work every time and I’ve never had to return for him to fix something – he gets it right the first time, every time. He helps patients with preventative care and only does work that is necessary. The office staff is friendly and treats each patient kindly and respectfully. I highly recommend Dr Mahallati for the whole family!

Jason R. from Costa Mesa, CA (Source: Yelp)


As someone who generally dreads the dentist and whose experiences with them have been largely negative, you can trust me when I say that Dr. Mahallati is one of the rare good ones. He listens patiently and closely to your concerns, explains the options clearly and honestly, and addresses them with exceptional care and skill. He uses state-of-the-art technology, leads a friendly and knowledgeable staff, and maintains the highest health and aesthetic standards.

The whole staff at Bay Dental are very professional and knowledgeable. We’ve been with Bay Dental for over a decade and they continue to exceed with their advanced technology. I’m very happy and satisfied customer. Definitely give them a try and you will not regret it. Thank you Bay Dental.

Chelsey B. from Los Angeles, CA (Source: Yelp)


Bay Dental is my childhood dentist. Even now that I reside in LA, I still come to Dr. Mahallati to get work done, not only because he’s extremely knowledgeable and gentle, but also because he’s the only dentist that’s never splashed water all over my face. I will also mention that I bring all my boyfriends to Bay Dental–the ritual typically being that Dr. Mahallati meets them before my dad does. Thank you Dr. Mahallati and his amazing staff for making the dentist my happy place 🙂

This review of Dr. Mahallati’s practice and the staff at Bay Dental has been long overdue. My family and I have been regular patients at Bay dental for years and are planning to remain so! Personally, I’ve been through a wide range of dental services from extractions to clear correct (Invisalign), and everything in between, and have been completely satisfied with the treatment experience of each service. Granted, I haven’t been the best patient in terms of losing things and breaking things, but Dr. Mahalati and staff will gladly remedy the issue—even by getting a same-day appointment if needed. The operations of bay dental are second to none. From the administration at the front desk, to the dental staff, the patient experience is really streamlined and effortless. Bless Dr. Mahalallati and Bay Dental staff for keeping my oral health in excellent shape.

My family and I have been going to Bay Dental for many years now and the staff is always great and very professional and they do great work!!

Nthabiseng M. from Santa Ana, CA (Source: Yelp)


I’ve been a client of Bay Dental, Santa Ana, Ca for as long as I can remember. Nice, clean facility. The staff is awesome. Friendly, professional, caring and efficient. Efficient in a way that u feel they love their jobs and treat every client who walks in with Respect, professionalism that’s expected from a medical office. Dr Mahallati is great. He knows his job quite well. Although it’s a business like any other business they never push for unnecessary work to be done and if you can’t afford the required procedures they try to work with you to find a better alternative. There are lots of other Dental offices one can visit around OC but Bay Dental by far will always be my number one pick.

Saul Alegria (Source: Google)


I love this place, they always do a great job. Since I visited this office for the first time, I was a little nervous to know what was wrong with my teeth. I had a tooth that was moving my teeth and they offered me braces. Now, I have my teeth aligned, they always pay attention to my treatment, and have helped me to have better hygiene. Apart from that, they are very friendly, the place is very clean, and every time I have an appointment, they notify me or accommodate my appointment to my schedule. if someone is interested in visiting, don’t hesitate and make an appointment. ⭐️⭐️⭐️⭐️⭐️

I have been coming to Bay Dental for about 17 years and I am very pleased with the service and staff. Dr. Mahalati and his staff always make sure I’m comfortable and not in pain whenever I get work done. I was always embarrassed with my smile, I had large spaces between teeth, had a gummy smile, and discolored teeth. I have gotten braces, a gum contour, an implant, and teeth whitening (at home kit), and I am very pleased with the results. I’m a lot more confident with my smile now! I don’t feel like I need to hide it anymore. I can wear lipstick confidently!  (…)

I have been attending Bay Dental for twelve years now I believe. I practically know most of the staff. The hours are flexible since I work the 8-5 shift. Since I’ve been coming here I’ve never had a bad experience always a good one and today I had an Excellent appointment. Gina, Sergio always kind and Joel (dental assistant) very friendly and funny. The hygienist Angie also very friendly and takes her time cleaning your teeth. Loved it. My teeth are extremely clean. Lastly, Dr. Shahin Mahallati has also treated me well and his dental advice has helped have a good dental healthcare. So if anyone is looking for an Amazing Dentist I Highly Recommend Bay Dental for any dental needs.

I’ve been coming to Bay Dental since 2000 (14 years +). Dr. Mahallati and staff are PHENOMENAL. He and the entire staff have always taken care of my dental needs and now I TRUST them to take care of my families dental needs. I knew my oldest daughter was going to need braces and Dr. Mahallati is taking care of that. She’s a very sensitive and nervous young teen but Dr. Mahallati and staff knew how to work with her and took it easy with her.  The office environment is always clean and fresh. Setting up appointments is easy and I like the text reminders. There’s plenty of parking and very accessible.

(…) Their entire staff are very friendly and professional. They are very organized and competent at correctly billing, and if you do have a billing question they are very friendly and will contact the insurance company directly to resolve any questions. To top it off, Dr. Mahallati is very friendly with the patients, and unlike many other dentists, will take the time to explain things in depth, and listen carefully to what you are asking him without rushing you into a procedure or purchase. It is EXTREMELY difficult to find a good, honest dentist these days (…). So I feel extremely lucky to have found Bay Dental and Dr. Mahallati…I HIGHLY, HIGHLY recommend them to everyone!!!!

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


I’ve been going here for dental care for the last 15+ years.  I can’t say enough great things about the staff and Dr. Mahallati.  My family and I have had all of our orthodontics done here as well.  The quality of care is exceptional. I live in Corona now, but I still go here because I feel so comfortable with everyone and the quality of care.  If you are looking for a dentist, I highly recommend that you try Bay Dental.

(…) a friend told me about Bay Dental. I have been a happy and satisfied patient for about 10 years, which is saying a lot about this dental practice! I have a complicated health history and need exceptional dental care practitioners. I found that the standard is perfection from the front of the office with Gina booking appointments, to the oral hygienists who take digital teeth images (x-rays) and assist the Doctors, to the Doctors themselves who are gentle yet fastidious in their work product and finally, to Sergio who handles the billing (insurance) paperwork. It is a remarkable team of professionals who do the work right. Another plus, the office has up-to-date technology they use for patient care. I have booked crown work that is completed, from start to finish, in just under 4 hours! A digital scan of the tooth is taken and then a crown is made inside the office. I’m in and out in just a few hours! No temporary crown and no follow up appointment! I had a need for surgical work and Bay Dental gave me several referral options. The professional that I selected had the same excellent work product as Bay Dental. Bay Dental deserves my 5 star rating!

I have been going to Bay Dental for about three years now. They are thorough, quick, professional and always on time. I believe they truly care. They do not look for reasons to do treatments you don’t need. They are also very nice. I highly recommend them.

James C. from Costa Mesa, CA (Source: Yelp)


Extremely pleased with Bay Dental.  The office staff is courteous, friendly and efficient. I have always received excellent dental care, thanks to the skill of Dr. Mahallati and his staff. Any procedures that were recommended were thoroughly explained, and my questions answered in an unhurried and careful manner that allowed me to make informed decisions about my dental care. Dr. Mahallati has even called me at home to offer suggestions or to clarify and elaborate on a previous question.  And I am impressed with the level of technology used by the Doctor and his assistants; none of my previous dentists were as well prepared in this area.  Lastly, I feel very confident that I am receiving outstanding dental care at a fair price at Bay Dental.

I had an unexpected toothache so I did not have an appointment. Received a call back in a timely manner; and an appointment scheduled shortly thereafter. I was in and out within an hour. While I didn’t like having a toothache the service could not have been better! And only a few short days later, and feel excellent. Thank you.

K. G. from Santa Ana, CA (Source: Yelp)


Before coming to this office, I hadn’t been to see a dentist in 3 years because of previous traumatic experiences. Now that I have found them, I’ll be in every 6 months for my cleaning! Everyone in the office was friendly and I felt really comfortable. I was in and out in one hour. Furthermore, not once did I feel like I was being lied to or sold to. My teeth are slightly crooked and I still have my wisdom teeth, so the dr asked me if my teeth bother me at all – when I said no, he told me that there was no reason to do anything unless I wanted to. Not pushing an unnecessary procedure just so you can charge me for it? Winner! I will be recommending bay dental to everyone I know!

Alma Alegria (Source: Google)


I love coming to Bay Dental because I love how clean the office always looks and the work you get done is always the best. I went to different places in the past, but Bay Dental made me change my mind about dental offices. Dr. Mahalati is really honest with the treatment, that’s why I decided to straighten my teeth because I knew I was going to have good results I also feel very comfortable every time that I go there because the staff is very friendly. Thank you, Dr Mahalatti and staff.

Mike R. from Santa Ana, CA (Source: Yelp)


Dr Mahallati, Sergio, and the staff at Bay dental have been serving me, my wife, and our family of five children for 15 years.  We’ve seen it all with regard to family dental work and the experience at Bay is always great!  Dr M. Does great work and Sergio always finds a way to balance the billing between our insurance coverage and what we can realistically afford.  We are never dissatisfied with the service, the work done, or the professional atmosphere!

(…) I was completely thrilled to find Dr. Shahin Mahallati who took my Insurance plan and along with his wonderful staff, I can’t speak highly enough of their care, expertise and professional knowledge and state-of-the-art interventions. As one who has “zero tolerance” to dental pain, after being in Dr. Maallati’s chair for almost two hours I experienced no pain, thoughtful intervention and I have happy teeth, crowns, etc. If you’re looking for a dentist and staff with expertise, compassion and “no pain”, look no further.

Outstanding dental care! Best Dental office I ever visited. Staff is professional, caring and highly skilled. I plan to be here for many years to come.

Dr. Mahallati is amazing and has one of the best dental team providing great care for patients; from Brandi (hygienist) who is incredible and takes her time when providing treatment, to Bonnie and Holly (RDH) and Joel (DA) who are so great at what they do and make you feel at home while treating you, and Gina and Sergio at the front. Everyone at Bay Dental works to not only provide the best care for the patient but make patients feel they are part of the family. I will definitely recommend Dr. Mahallati and his team to everyone.
