You put time, money, and patience into getting your teeth straightened. A retainer is what keeps all that effort from going to waste. Maybe you just finished orthodontic treatment, or maybe it’s been a few years and you’re noticing things shifting around a bit — either way, a good retainer holds everything right where it belongs.
Here’s how we handle it at Smiles Dental Spa. Dr. Shirley Zhao looks at your bite, your alignment, your jaw structure — the whole picture — using digital dental X-rays and 3D dental imaging. Then she recommends the retainer type that actually fits your life. Not some generic solution. Something that works for your mouth, your comfort level, and your history.
We get a lot of Tracy families walking through our doors who’ve never dealt with orthodontics before. It can feel like a lot. So we slow down, explain every option, and answer whatever questions come up — no rushing, no pressure. You’ll leave knowing exactly what the plan is and why. That’s really the heart of how we approach comprehensive dental services all under one roof.

Since 2013
Retainers play a vital role in orthodontics by stabilizing teeth in their new positions after braces or Invisalign.
Retainers play a vital role in orthodontics by stabilizing teeth in their new positions after braces or Invisalign. Teeth naturally have a tendency to shift back to their original places—the period after active orthodontic treatment is critical as bone and gums adjust to the new alignment. Our experienced Tracy dentist carefully monitors both baby teeth and permanent teeth throughout this phase. Practicing good oral hygiene, including brushing and flossing, helps maintain results and overall oral health.
Custom-made to comfortably fit your mouth, orthodontic retainers hold your teeth steady while your jawbone hardens around them in the correct position. This prevents relapse, maintaining your hard-earned results for a lifetime.
Dr. Zhao will highly recommend the best type of retainer for your unique treatment plan and lifestyle. For children who have lost a baby tooth, she may also include space maintainers to preserve proper spacing until the permanent teeth erupt. Patients typically wear retainers full-time at first, then transition to nighttime wear for ongoing maintenance.
Want something nobody can see? Clear retainers — some people call them Essix retainers — are basically invisible. They're made from thin, transparent thermoplastic that snaps right over your teeth. Honestly, most folks won't have a clue you're wearing one. Each one gets custom-fabricated from precise impressions or digital scans. They're light, they're comfortable, and popping them out to eat or brush takes two seconds. For Tracy's busy professionals and teens who don't want anything obvious on their teeth, these hit the sweet spot between looking good and doing the job. One heads-up, though. Heat warps them. And Tracy summers? They regularly blow past 100°F. We can't tell you how many melted retainers we've seen between June and September — people leave the case in a hot car and come back to a warped mess. Just keep it somewhere cool. That's it. Do that and your clear retainer will last way longer than you'd expect.
This is the one you're probably picturing right now. Acrylic base sitting against the roof of your mouth (or behind your lower teeth), thin metal wire wrapping around the front. It's the classic design. Been around forever because — honestly — it just works. The big advantage? Adjustability. If your teeth shift a little, Dr. Zhao can tweak the wire instead of making a whole new appliance. That saves time and money. They're tougher than clear retainers too — we're talking several years of solid use with basic care. And here's a fun detail kids love. They get to pick colors for the acrylic part. Sounds small, right? But for a seven-year-old who's nervous about wearing something in their mouth every night, choosing their favorite color turns it into something they actually own. Tracy's got a booming population of young families — we see tons of these kids — and that little bit of personalization makes a real difference in whether they actually wear the thing.
Some people know themselves well enough to admit: "I'm not going to remember to put a retainer in every night." Fair enough. That's exactly who fixed retainers are for. These are thin wires cemented to the back of your front teeth. Can't see them. Can't lose them. They work 24/7 without you lifting a finger. Dr. Zhao bonds a custom-shaped wire to each tooth using dental composite — same material as tooth-colored fillings — and the whole appointment runs about 30 minutes. Painless, straightforward. Now, the trade-off. You've got to be a little more intentional with oral hygiene. Flossing around that wire takes some getting used to, and we recommend floss threaders or a water flosser to keep things clean under there. Our hygienists pay extra attention to bonded retainer areas during your regular dental cleanings because tartar loves to build up in those spots. Tracy's water supply is mineral-rich, which means calculus forms faster than you might expect — so staying on schedule with cleanings really matters here.
Kids lose baby teeth early sometimes. Decay, an accident on the playground, an extraction — it happens. The problem is that surrounding teeth don’t just sit still. They drift into the gap. And when the permanent tooth is finally ready to come through, there’s no room. That means crowding, misalignment, and possibly way more orthodontic work later on.
A space maintainer is a simple fix. It holds the gap open until the adult tooth’s ready to erupt. Each one’s custom-made for the child’s mouth, and depending on where the missing tooth is and how old the kid is, it can be fixed in place or removable.
We place a lot of these at our Tracy office. Over 100,000 residents in this city now, and the demographics skew heavily toward young families — so pediatric dental care is a huge part of what we do. Dr. Zhao explains the appliance to both parents and the child, usually with models so the kid can actually see what’s going into their mouth. A calm kid who understands what’s happening? That kid cooperates. Makes the whole experience smoother for everyone.
After we place it, we schedule follow-ups to monitor things and track how the permanent tooth is progressing. Once it starts erupting, the maintainer comes out. Quick and comfortable — nothing dramatic.
Proper oral hygiene is essential for retainers and space maintainers to function well and stay comfortable:
Maintaining your appliances protects your investment and ensures your smile stays healthy and aligned.
Yes. Absolutely yes. Emergencies don’t check your calendar first, and neither do we. Broken retainer wire? Knocked-out tooth? Woke up at 3 a.m. with a throbbing abscess? Smiles Dental Spa provides emergency dental services — same-day emergency exams, emergency extractions, abscess drainage, the works.
Dr. Zhao also keeps a 24-hour emergency phone line open so you’ve always got someone to call — even on weekends, even after hours. Sudden swelling, bleeding that won’t stop, pain that’s through the roof — call us immediately. We’ll either get you into the office or walk you through what to do until we can.
Orthodontic emergencies count too. A broken retainer, a loose space maintainer, a wire jabbing into your cheek — don’t sit at home hoping it’ll fix itself. It won’t. A quick visit now saves you a lot more trouble and discomfort down the line.
One hundred percent. There’s this stubborn myth that braces and retainers are just for teenagers. Not true. The American Association of Orthodontists says roughly 1 in 3 orthodontic patients is an adult now — and we see that same trend right here in Tracy.
People come in for all kinds of reasons. Maybe they never had braces growing up. Maybe they did, stopped wearing the retainer (it happens to a lot of people), and their teeth gradually drifted back. The thing is, it’s never too late to fix your alignment and your bite.
We evaluate adult patients the same thorough way we evaluate everyone — comprehensive oral exams, digital X-rays, 3D imaging to look at bone density, gum health, tooth positioning. Got periodontal issues? We handle those first with scaling and root planing or periodontal maintenance before starting any orthodontic appliances. Healthy gums have to come first. That’s non-negotiable at any age.
And our multilingual staff — fluent in Cantonese, Chinese, Tagalog, Spanish, and English — means every patient can talk through their concerns and options in whatever language feels most natural. That kind of communication really does matter, especially for decisions about something as personal as your smile.
We actively support your smile maintenance journey, ensuring orthodontic success long after braces are removed with expert guidance and follow-up care.
A caring, communicative approach with every visit
Advanced technology for accurate, safe diagnostics
Flexible scheduling for busy lifestyles
Expertise in both family dental care and cosmetic dentistry procedures

Most custom retainers at our 1431 N Tracy Blvd location are ready within 1-2 weeks after your initial impressions or digital scans are taken. We use precise digital scanning technology to ensure an accurate fit, which minimizes the need for adjustments or remakes. If you’re in a time crunch, ask our team about any expedited options when you call.
Retainer costs at Smiles Dental Spa generally range depending on the type — clear Essix retainers and Hawley retainers are priced differently, and many dental insurance plans cover at least a portion of the cost. We recommend calling our office at 1431 N Tracy Blvd to get a specific quote based on your treatment history and insurance coverage. Our team can also walk you through flexible payment options if needed.
Contact our Tracy office as soon as possible — even a few days without a retainer can allow teeth to begin shifting, especially in the first year after orthodontic treatment. Dr. Zhao can typically schedule a replacement appointment quickly, and having your previous digital scans on file may speed up the fabrication process. Don’t wait and hope things stay in place; call us at our N Tracy Blvd location right away.
Children are generally evaluated for space maintainers as soon as a baby tooth is lost prematurely, which can happen as early as age 4-5 due to decay or injury. Early intervention is important because neighboring teeth can begin drifting into the gap within just a few months, potentially complicating future orthodontic treatment. Dr. Zhao recommends scheduling an evaluation within 2-4 weeks of an early tooth loss.
We provide orthodontic consultations and treatment planning for both children and adults at our 1431 N Tracy Blvd office — in fact, a significant portion of our retainer patients are working adults in the Tracy area. Adult orthodontic needs are just as common as pediatric ones, and Dr. Zhao tailors every treatment plan to the individual’s age, lifestyle, and dental history. There’s no age cutoff for wanting a straighter, healthier smile.
Most patients are seen every 6-12 months for routine retainer check-ups, though Dr. Zhao may recommend more frequent visits in the first 6 months after completing orthodontic treatment. These appointments allow her to monitor your alignment and make any minor wire adjustments if needed, particularly for Hawley retainer wearers. Staying on schedule with check-ups at our Tracy office is one of the best ways to protect your long-term orthodontic results.
All necessary orthodontic imaging — including digital dental X-rays and 3D dental scans — is available right here at our 1431 N Tracy Blvd office, so you won’t need referrals to outside imaging centers. Having everything under one roof means Dr. Zhao can review your full dental picture the same day and begin building your treatment plan without delays. This is especially convenient for Tracy families managing multiple appointments across busy schedules.
