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

Stephen V. from Costa Mesa, CA (Source: Yelp)


(…) The staff is great, everyone is friendly and has a good sense of humor. They always run on time which I appreciate. Tiffany is awesome! She cleans teeth like a boss. Dr. Cross is great too, nice guy easy to talk with, gave me my favorite filling so far. They didn’t try to upsell me and replace my one silver filling (which I acquired at my first California dentist) like my previous dentist did as it is structurally intact and has a few years of life left. Very honest and straightforward. 5 stars hands down. Don’t change anything.

I waited a long time to get three crowns put in because it was expensive and time-consuming.  I finally chose Dr. Cross to do the work, although we have a dentist in the family, because he has integrity and does a great job.  The crowns feel natural and aren’t bothering me a bit.  If you have to get them done, do them right the first time and go to Dr. Cross. He is seriously an artist when it comes to crowns and restorative work.

I highly recommend Dr. Cross and his wonderful staff. Every time I visit I’m greeted with warmth and smiles. The Administrative staff is excellent. Dr. Cross does amazing pain free work – so much so that I fall asleep in his chair every time I get in it. Well, the same can be said for my hygienist Trish. I fall asleep in her chair too. Needless to say I think the world of OC Lifesmiles and I recommend them and sing their praises whenever the subject of dentistry comes up.

Hands down the best dentist! I had a full set of veneers and the entire experience went smoothly and my teeth look amazing. The staff is not only knowledgeable but always welcoming and cheerful. If you’re looking for an exceptional dental experience don’t hesitate to make Dr. Cross and OC Lifesmiles your family dentist!

My family and I have been going to OC Smiles for at least 10 years. I trust my smile with Dr. Cross and staff. With our busy lifestyle they never forget to remind us of when it’s time for our dental check-ups. They are trained professionals that I respect with our family’s dental needs!

Chris J. from Big Bear City, CA (Source: Yelp)


I was recommended to go to Dr. Cross’s office, OC Lifesmiles, by some good friends of mine. I hate the dentist and I was nervous to get back in the chair. Dr. Cross and associates made my visit very painless. The atmosphere in their office made me feel very comfortable. This office is very clean and presentable with nice chairs and equipment. I’m glad I found a dentist that I can trust. This office operates efficiently from the receptionists and dental assistants to Dr. Cross himself.  I will be going to this dentist office as long as I live in the Orange County area.

Jon T. from Santa Ana, CA (Source: Yelp)


Used to hate going to the dentist… But then I came here!  Dr cross and his staff made me comfortable and at ease.  I’d recommend this office to any of my friends and family.

Jesse R. from Newport Beach, CA (Source: Yelp)


Dr. Cross and his staff are the best!  Super friendly and just an all-around great dentist.  His location is easy to get to, parking is simple, and his office is warm and friendly.  Highly recommend!  A++

My wife and I have been patients of Dr. Cross since he moved into the Newport Beach office. On every visit, we have experienced a warm and friendly greeting from every staff member as well as Dr. Cross. This welcoming culture reinforces the fact that when combined with Cross’s skill as an accomplished state-of-the-art dentist, there is no better dental health experience available in Orange County.

Nicole K. (Source: Google)


I’ve been a patient of Dr. Cross for over 5 years. The whole office is stellar!!! But the legitimate care that Dr. Cross has for preserving my oral health is unparalleled. He does not do unnecessary work and is meticulous in making sure that every time I leave his office my teeth are in the best shape possible. Major shout out to this crew for turning a lifelong dental phobic into a girl that now goes in an EXTRA time for a third cleaning every year!

Melinda Nelson (Source: Google)


I am a long time patient and actually look forward to going into the office for cleanings and work. The staff, and Dr. Cross, know my name and are always welcoming. Their smiles work wonders to ease a person’s tension before sitting in the chair. I can’t say enough good things about this practice..

Richard J. from Newport Beach, CA (Source: Yelp)


Dr John Cross and his professional team are exceptional. Warm caring environment, excellence in procedure and concern for your comfort. My wife and I have great confidence in the care we receive…and we are quite literally treated “as Family.” Dr Cross offers an Annual Plan that we have taken advantage of for years…our semi-annual cleanings are covered along with a substantial reduction in other services should they be required during the year. Great team, fair pricing, caring environment, and outstanding commitment to my families dental health!

Scott W. from Newport Beach, CA (Source: Yelp)


Dr. Cross is an exceptional dentist. With state of the art equipment, you would think they would be more expensive, but they are not. I have been to several dentists in the OC area, but OC Lifesmiles is the best option. Progressive, but yet affordable, a rare find in this overpriced area!

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


Yesterday I completed another regular follow up/cleaning with Dr. Cross’s office.  As always, I only have great things to say about my visit. The entire staff is always very friendly and pleasant from the second I walk through the door. I have had a couple of different hygienists over the years and have been very happy with each one.  Thanks again to Dr. Cross, the staff, and the hygienists for making a trip to the dentist as good as it could be.  See you in 6 months.

George B. from San Diego, CA (Source: Yelp)


It had been a while since my last cleaning. My teeth had so much plaque my mouth looked like a trophy store. My hygienist Trish took charge and sorted all of that out, plus she made sure I didn’t have any cavity creeps. The girls at the front desk were super helpful as always, and Dr. Cross is like a dentist superhero. The guy should walk around with a cape. 5 Stars for sure!!!

Hannah H. from Irvine, CA (Source: Yelp)


Dr. Cross is the best dentist I’ve ever had. And I used to have a very bad fear of the dentist. One of the assistants seem new like they are still learning. But that’s okay, the team is really kind, and Dr. Cross is very involved if they are still learning. Amazing dentist!!! I don’t live in the area anymore but I schedule my appointments here when I visit my family in Newport.

Scott Winn (Source: Google)


They are progressive and truly care about you and your health. Many of the local Dentists are overly expensive, yet OC Lifesmiles has state of the art equipment and yet is very cost-effective. I have been to many dentist’s in the area before finding them, I am grateful that I did.

Brittaney P. from Garden Grove, CA (Source: Yelp)


I’ve been putting off crucial dental work for over 10 years as I have an extreme fear of the dentist. I finally worked up enough courage to schedule an appointment with OC LifeSmiles to see what they could offer me in regards to my fears. Not only is their staff Grade A, but they were able to sedate me during my procedures to ensure that my fears were demolished and that I was more than comfortable. I am so impressed with this dental office that I would instantly recommend them to anyone who is looking for a new dentist. Their kind hearts and expertise in dental work is truly one of a kind! I highly encourage to seek help from OC LifeSmiles.

Ayca M. from Redondo Beach, CA (Source: Yelp)


(…) The front office staff was great, and the dental assistants I’ve had each time I’ve gone have been really nice and helpful as well. Dr. Cross himself is very patient, communicative, and thorough. I had a porcelain veneer redone on a tooth a few years back from an accident I had as a child (Side note: It’s not very wise to dive into three feet of water), and I wasn’t happy with the way it looked. This was my front tooth, so I was a little self-conscious about the way it was contoured and chipped. Dr. Cross did a fantastic job fixing it up, and I’m much happier with the way it looks again!

Gareth E. from Newport Coast, CA (Source: Yelp)


Had an onlay and fillings done. Very professional and high-tech. I was in and out within 90 minutes with an onlay and 2 fillings. No pain at all during or after. Thanks, Dr. Cross and Tiffany.

Cameran L. from Newport Beach, CA (Source: Yelp)


The best dentist in town.   The staff is so great and flexible.  I had to rearrange my appointment a number of times and they were so easy to work with. Every time I walk through the door I’m great with smiles. Very welcoming and professional.

The most trustworthy dentist I’ve ever visited! Dr Cross has been exceptionally honest with me and all of my family members, as he has recommended more practical (and less invasive and less costly) solutions to dental concerns versus other dentists that we have seen for the same issues. As our circumstances and insurances have changed over the years I keep coming back to him and being reminded how GREAT it is to be able to fully trust exactly what Dr Cross is telling us!

Paul Carlin (Source: Facebook)


Dr Cross is very professional and yet he gives a personal touch. The staff is always been friendly and helpful. I always feel relaxed knowing his work is excellent.

David D. from Irvine, CA (Source: Yelp)


I have been going to Dr. Cross for well over 10 years.  Dr. Cross and his staff are always on time.  The office is beautifully decorated and he uses the latest technical equipment. My teeth are in excellent condition, although they were not when I first started seeing him.  When I had an emergency he saw me the same day.  You can’t find a better dentist than Dr. Cross.

Susan A. from Trabuco Canyon, CA (Source: Yelp)


Hands down the best dentist!  I had a full set of veneers and the entire experience went smoothly and my teeth look amazing. The staff is not only knowledgeable but always welcoming and cheerful.  If you’re looking for an exceptional dental experience don’t hesitate to make Dr. Cross and OC Lifesmiles your family dentist!

Great service with friendly staff. Reasonable prices too!

Jill Allen (Source: Google)


Friendliest staff from the minute you walk in the door to the back-office staff. Extremely thorough yet gentle. Savannah, Marissa, Tiffany & Dr. Cross exceeded my expectations and made me feel very relaxed and comfy. Highly recommend this office to anyone who has dental anxiety, they take it right away!

Karen Meier (Source: Google)


My family has been patients for years. We would not change a thing. Their front office staff is efficient, friendly and communicates extremely well. Their dentist, Dr. Cross is professional and quick and an expert. The hygienists are also very good. All around it’s a great dental practice to choose to use – highly recommend OC Lifesmiles!

Carrie Berg (Source: Google)


Everyone at OC Lifesmiles is very nice and professional. Dr. Cross is a great dentist, Tiffany does great with my two young daughters, they actually don’t mind going to the dentist. Trish always does a great cleaning and Kaycie in the front office is very sweet.

Donna W. from Yorba Linda, CA (Source: Yelp)


This is a highly competent office with excellent staff members.  Tiffanie is an amazing hygienist who takes quality time with each of her patients. Dr. Cross is very professional with a caring approach to all his patient’s needs and concerns.  Wonderful experience and would highly recommend this office to friends and family.

Scott F. from Newport Beach, CA (Source: Yelp)


Dr. Cross, his staff, operation, and dental skills are exemplary.  7 years and they’ve always performed high-quality dentistry for a fair price, since I pay cash. Highly highly recommend this outfit.

Frank Hodgson (Source: Google)


I can’t say I know too many people who say that going to the dentist is an enjoyable experience. However, I can say all of my visits have been rewarding not only in the medical sense but the staff is genuinely interested me as a person. I do and have recommended OC Lifesmiles to my friends and associates.

Chris Skibba (Source: Google)


I have been a patient of OC Lifesmiles for 7 years now, and I have only great things to say about Dr. Cross and his team. If your current Dentist is simply a teeth cleaner then you owe it to yourself to give OC Lifesmiles a look. Cleanly put, OC Lifesmiles took me, the classic patient who flosses about 3 days in a row before my biannual cleaning and has transformed me into a gum care believer. My gums were in terrible shape, but fine according to my prior dentist. Dr. Cross helped me set a plan in place to get my gums back to a very healthy state. Simply put, I owe them a lot for that. Trust, me, I am not a review writer or reader, but I felt compelled to share briefly with you my respect and appreciation for the folks at OC Lifesmiles. Thanks Guys

Camaro S. from Irvine, CA (Source: Yelp)


Extremely happy with my visit. I have a very serious fear of the dentist and Dr. Cross made my visit amazing. Will be back for sure.

Carrie B. from Newport Beach, CA (Source: Yelp)
