Changing Smiles, Changing Lives

Welcome to Delta Smiles! Orthodontist in Brentwood and Antioch, CA!

Delta Smiles is an orthodontic practice with two offices in East Contra Costa County, one in Antioch and one in downtown Brentwood. Two orthodontists treat children, teens, and adults at both locations, using metal and clear braces, Invisalign clear aligners, and early growth guidance for children whose jaws are still developing. The first exam is complimentary at either office, and no referral from a dentist is needed. Both offices are open Monday through Friday.

Why Families Choose Delta Smiles?

Two specialists, not one, both trained in nothing but orthodontics. Decades of roots in East County. And 791 five-star reviews across our two offices - the kind of record that isn’t built without getting it right, visit after visit.

That focus matters most on the cases that aren’t simple: an impacted canine, a bite that needs correcting before the growth spurt ends, an adult whose teeth have shifted since a first round of braces.

A Modern Orthodontic Experience Beyond Straight Teeth

Great orthodontic care is about more than the final smile. We want patients to feel supported, understood, and involved along the way, with thoughtful care that considers overall health and a team that makes treatment something to feel good about.

Patient Rewards Hub

Points come from good brushing, on-time visits and following the treatment plan, and patients trade them for gift cards. It’s a favorite with our younger patients.

Airway Orthodontics

Mouth breathing, snoring and a narrow upper jaw can be connected. We evaluate breathing patterns and jaw development, with 3D imaging when an airway question calls for it.

Treat Everyone Like Family

Nervous first-timers get extra time here. Staff walk kids through each step before it happens, and parents go home with clear instructions for whatever comes up next.

The Technology

A handheld 3D scanner replaces putty impressions. Cone beam imaging is used only when a diagnosis needs it, and every digital plan is reviewed by a doctor.

What Your First Visit Looks Like

About an hour with one of our doctors, plus any records the case needs. You leave with a plan and full cost, decide at home, and owe nothing.

Making Treatment Affordable

We’re in network with Delta Dental and work with most plans covering orthodontics. The balance goes on a no-interest in-house plan, often $0 down, or CareCredit.

Frequently Asked Questions

Whether you’re considering orthodontic treatment for yourself or your child, it’s natural to have questions. Here are answers to some of the most common questions patients ask about treatment at every age.

What's the difference between an orthodontist and a dentist who offers braces?

An orthodontist completes an accredited residency after dental school, two to three years of full-time training in moving teeth and guiding jaw growth, and then limits their practice to that work. A general dentist can legally provide aligners without any of it. Both of our doctors are orthodontic specialists.

Whichever is closer to home or school. Treatment, doctors and records are identical, and families switch between them freely.

Usually within a week or two. Call the office nearest you or request a time online and we’ll find the earliest appointment that fits.

We schedule after-school slots for students and try to book siblings back to back so one trip covers the family. Both offices are closed on weekends. More questions are answered on our treatment FAQ.

I was told by my son's dentist that he needed to get his teeth done with overbiting and overcrowded teeth. I was looking which one's under our insurance and stumble on to Delta Smiles. First evaluation, staff are friendly, and very thorough with what is going on with my son's teeth problem. "Eddy" is one of the friendly staff that we met and handled my son, and made my son really comfortable and not be scared and nervous with having his braces and changing braces. The thing about this Dental office is they give you points every visits which you can use to get gift cards which is really great. A lot of things to do if you download their app as well. My son have made a great improvement in regards with widening his jaw and his teeth is slowly becoming not overcrowded and crooked. Will update the review once we are done with our treatment .

I had a really great experience with this office. From the moment I walked in, everyone was kind, welcoming, and very professional. They made me feel comfortable throughout the entire process. I especially want to thank Eddy, who placed my Invisalign. He was incredibly attentive, patient, and professional. He took the time to answer every question I had about the treatment and made sure I understood everything before we started. I never felt rushed, and I really appreciated how much he cared about making me feel confident and comfortable. I also want to thank Dr. Brent Sexton for creating my Invisalign treatment plan. He explained everything clearly and offers excellent financing options that make Invisalign much more affordable for people who want to improve their smile. I'm very happy with my experience so far and would definitely recommend this office to anyone looking for a caring, professional team for their dental or Invisalign treatment.
My daughters have had a wonderful experience here!

My kids just started their expanders at Delta Smile, and I couldn’t be happier with the experience. Every single person in this office is so kind, patient, and welcoming. Erica, who helped us during our first consultation, was incredibly friendly and made the whole process feel easy and comfortable. Eddie, who took the scans and placed the expanders, was amazing — gentle, professional, and so good with my kids. Dr. Sexton was wonderful as well, explaining everything clearly and making sure my kids felt confident and calm. I also really appreciate the front office staff. They understood how important timing is for me with two kids, and they were so patient while helping me find appointment times that worked for both of them. It made such a difference. Overall, Delta Smile has been a great experience for our family, and I’m grateful for the care and kindness they’ve shown my kids.

They are great with kids. We haven't met the medical team side yet but we are looking forward to our treatment and we will be with this office for the next two years....or more 😬 Consider them for your orthodontics services.

I’ve been a patient at Delta Smiles for over three years, and I can say without hesitation: this is hands-down the best dental experience I’ve ever had. And yes—I’m someone who actually looked forward to dental appointments. That alone should tell you something. Between the Brentwood and Antioch locations, there are staff members too numerous to name individually—and that’s a good thing. Across both offices, I’ve never once had a bad experience. Not a single one. Every interaction, every visit, every phase of care has been consistently excellent. From the moment you walk in, every single staff member is warm, professional, and genuinely kind. The entire process is smooth, efficient, and stress-free—from scheduling to check-out. Payment is easy, appointments are flexible, and they respect your time (which is rare these days). Huge shout-out to the doctors—Dr. Sexton and Dr. Louie—both absolute pros. Skilled, patient, and approachable. You never feel rushed, and they take the time to explain things in a way that actually makes sense. And the staff… honestly, just good people. Annie, Melva, Janet, and Eddy (Go Pats 🏈)—you’re incredible. Friendly, funny, compassionate, and consistent every single visit. The kind of team that remembers you, checks on you, and treats you like a human instead of a chart number. From the initial consultation, through every adjustment, all the way to getting fitted for my retainers after the brackets came off, the experience was nothing but a pleasure. Everything was organized, transparent, and reassuring the entire way through. One moment that sealed it for me: I was running late at the end of the day, and instead of canceling or rushing me out, they stayed open—just for me. That’s not policy. That’s heart. That’s the kind of personal touch you don’t forget. Because of the trust and experience I’ve had here, both of my children will be patients here as well—and that says everything. If you’re looking for a dental office that combines top-tier clinical care with genuine kindness, humor, and humanity, this is it. Delta Smiles doesn’t just take care of teeth—they take care of people. I’m incredibly grateful for this team and recommend them without reservation. 👏👏👏

I used Delta smiles over Covid, for my ortho needs and now my kids are starting their adventure into orthodontics. Gals at the front dest and so sweet and helpful, all dr’s are friendly and amazing, their assistants are great too. Eddy today put on my daughter’s expander and was super helpful in helping explain how it works and the dos and don’ts.

My daughter recently became a patient at Delta smiles when we were referred by our dentist to start her orthodontic journey. We were both a little anxious and unsure of what the process was going to look like. However, from my daughter‘s consultation to her most recent visit having her first expander installed, the team has been amazing. Everybody is so friendly and welcoming and has made my daughter feel very comfortable, even when the aftermath for the first few days after the spacers and then expander were installed isn’t comfortable. We were so fortunate to have Eddy on our last visit when her expander was installed. He talked us both through the entire process and let my daughter ask as many questions as she needed before he actually glued it in. He let her play with the mold they had made of her mouth (which she thought was so cool) and made the whole process seem exciting to her. It’s reassuring and comforting to be able to sit there during her appointment and have everything explained and be sent home with detailed instructions for questions that might arise later. Eddy even went above and beyond and sent my daughter a note in the mail with some stickers to check on her and see how she was feeling after installation and to remind her about proper brushing with the Appliance! We are looking forward to working with the entire Delta Smiles team over the next couple of years during my daughter‘s phase 1 process.

I have been waiting and researching where to get braces for my son for over year and we are so thankful to have found such a wonderful office. Being a ortho/dental assistant myself, it was important to me to find an office that staff employment longevity was a must. This shows assistants have the skill and experience, AND that they are happy with where they work and are taken good care of which all will reflect on the care of my son. Everyone is so organized, friendly and thorough. My son was very nervous and Elizabeth took her time with him, explaining each step and put his nerves to rest. We will continue to refer everyone we know to Delta Smiles. Thank you thank you thank you.

We've been long-time patients at Delta Smiles, and now we're nearing the final stretch with our youngest child’s treatment. From the very beginning, the team has made us feel truly welcome. They’ve consistently gone above and beyond to work with our insurance providers, ensuring we received the full benefits available to us. What sets Delta Smiles apart is their kindness and genuine care for their patients. Scheduling is a breeze, with flexible appointment times that fit seamlessly into our busy lives. Every visit has been smooth, professional, and reassuring. We’re so happy with the level of service and care that we’ve recommended Delta Smiles to countless friends and coworkers—and we’ll continue to do so. They’ve earned our trust and gratitude every step of the way!

I came here after switching from my previous dentist. I consulted with a couple of other orthodontists before making my decision, and I am so glad I chose Delta Smiles. They are the best of the best. This orthodontic office has shown me what a true dental practice should look, feel and operate like. The whole team is exceptional, from the ladies at the front desk to the dental assistants, practice administrator, and, of course, the orthodontist. They genuinely care and take great pride in their work. These folks are dedicated to delivering excellence. Beyond their expertise, I have never been treated with such kindness. Delta Smiles is a true gem, and I am grateful that this place exists.
