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.
Years of Orthodontic Experience in East County
Your family’s smile comes first here. Dr. Brent Sexton and Dr. Tiffany Louie are orthodontic specialists, and both completed full-time residencies focused entirely on orthodontics after dental school. Orthodontics is the only care we offer. We don’t do cleanings or fillings. We straighten teeth, guide jaw growth in children, and give families smiles they’re proud to share.

Find the Right Orthodontic Treatment for You
Every smile is unique, which is why we offer a variety of orthodontic solutions to fit your needs, lifestyle, and goals. Whether you’re looking for the reliability of traditional braces or the convenience of clear aligners, our team will help you choose the treatment that’s right for you.

Metal Braces
A proven orthodontic solution that effectively corrects everything from simple alignment concerns to complex bite issues. Today's metal braces are smaller, more comfortable, and more efficient than ever before.

Clear Braces
Enjoy the effectiveness of braces with a more discreet appearance. Clear ceramic brackets blend naturally with your smile, making them a popular choice for teens and adults seeking a less noticeable treatment option.

Invisalign® Clear Aligners
Straighten your teeth with virtually invisible, removable aligners. Invisalign® offers a comfortable and flexible alternative to braces, allowing you to eat, brush, and floss with ease throughout treatment.
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.
Treatment for Every Stage
Orthodontic care for every age and stage, from early evaluations for children to flexible treatment options for teens and adults. We also handle airway-focused care, retainers, complex cases and retreatment, and orthodontic emergencies.
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.
Which of your two offices should we visit?
Whichever is closer to home or school. Treatment, doctors and records are identical, and families switch between them freely.
How soon can we get in for a first exam?
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.
Do you have appointments outside of school hours?
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.
