Your Trusted Tracy Dentist
Since 2013
Dentistry isn’t just about fixing problems—it’s about preventing them before they start.
Many dental conditions develop quietly, without pain or obvious warning signs. Regular exams and modern diagnostic tools help detect subtle changes, including plaque and tartar buildup, so we can act early with effective dental cleaning and care.
At Smiles Dental Spa, your trusted Tracy dentist, prevention is at the heart of everything we do. We provide thorough evaluations, clear communication, and individualized care so you understand your oral health and feel confident in your treatment plan.
Flat, two-dimensional X-rays? That's old school. At our Tracy office, we use cone beam computed tomography (CBCT) — basically a 3D scan that shows us your teeth, jawbone, nerves, and soft tissue in incredible detail. It's like going from a blurry snapshot to a high-definition movie. This changes everything about how we plan treatment. Need a dental implant? We can evaluate bone density down to the millimeter. Got an impacted wisdom tooth hiding at a weird angle? We'll map its exact location before we ever pick up an instrument. Complex root canal anatomy that'd be invisible on a regular X-ray? We see it clearly now. And here's the kicker — the whole scan takes under 30 seconds with way less radiation than a medical CT. Tracy's grown to over 100,000 residents, and honestly, our community deserves technology that keeps up. Faster diagnoses. Fewer surprises mid-treatment. Better results across the board. That's why we invested in it.
This isn't a quick peek inside your mouth. Not even close. A comprehensive oral exam is a full, systematic deep-dive into your oral health — and it's the backbone of everything we do at Smiles Dental Spa. Dr. Shirley Zhao checks your teeth, gums, bite alignment, jaw joints, tongue, cheeks, throat. All of it. We kick things off by going through your complete medical and dental history. Why? Because your body doesn't separate "mouth health" from "everything else health." Diabetes, heart disease, certain medications — these all shape how we approach your care. We'll also ask what's bugging you. Sensitivity? Grinding at night? Something cosmetic you've been thinking about? We actually want to hear it. Then Dr. Zhao gets to work. She checks every single tooth for decay, evaluates your existing fillings and crowns, and measures gum pocket depths to screen for periodontal disease. Combine that with digital X-rays — and 3D imaging when the situation calls for it — and we've got a complete snapshot of where things stand right now and where they're trending New to our practice? Haven't been to a dentist in a while? The comprehensive exam is always step one. It lets us build a personalized treatment plan that actually makes sense for your needs, your budget, and your life. Check out our full range of dental services to see how we support every member of your family.
Digital X-rays are one of our most valuable diagnostic tools — and they're nothing like the film-based versions you probably remember from childhood. Our digital sensors cut radiation exposure by up to 80% compared to traditional film Images pop up on screen in seconds. No darkroom. No waiting around. We generally take two types during your exam. Bitewing X-rays capture the crowns of your upper and lower back teeth in one shot — perfect for spotting cavities hiding between teeth and checking how your existing restorations are holding up. Periapical X-rays show the whole tooth, root tip included, so we can identify infections, bone loss, and anything lurking below the gumline. New patients (or anyone due for a full update) might need a full-mouth series or a panoramic X-ray that sweeps across your entire jaw in one image. Super helpful for wisdom tooth evaluation, implant planning, and overall bone health assessment. Here's something interesting about Tracy specifically — our water supply comes from Central Valley groundwater, which carries higher mineral content than a lot of California communities. Minerals are generally great for teeth, but we use X-rays to keep an eye on any extra calcification or tartar buildup that hard water can encourage over time.
Sometimes you're not coming in for a routine checkup. Something hurts. A tooth cracked. There's swelling that won't go away. Maybe a crown feels off. That's what a focused problem evaluation is for. Dr. Zhao zeros in on exactly what's bothering you. We take targeted X-rays, run vitality tests on the affected tooth, and assess the surrounding gum tissue and bone. The goal? Figure out what's going on — accurately and fast — so we can talk through your options that same day whenever possible. This is especially important if you're in sudden pain or you've had some kind of accident. No waiting weeks for a full exam. We handle the urgent problem first, then schedule any follow-up care you need. And for patients who get anxious about dental visits (no judgment — it's super common), we offer nitrous oxide sedation to keep you comfortable throughout.
After your initial comprehensive exam, future visits are usually a periodic oral evaluation. Think of it as a wellness check for your mouth. Shorter than the full exam, sure — but don't underestimate it. These visits let us track changes over time and spot new issues before they turn into expensive problems. Here's what we're looking at: Are your gum measurements holding steady, or is there recession creeping in? That tiny spot of early decay we flagged last time — did it remineralize with fluoride, or has it gotten worse? Is your bite shifting? We answer these questions every single visit. Most healthy adults do great on a six-month schedule. But if you've got a history of gum disease, you're in the middle of orthodontic treatment, or you have certain medical conditions, we might want to see you every three to four months. We tailor the schedule to you — not some cookie-cutter calendar. Tracy's been growing fast. A lot of residents are finding a dentist here for the first time. If that's your situation — welcome. Seriously. We love building long-term relationships and watching families grow right alongside our practice.
Let's just say it. A lot of people dread cleanings. Maybe you had a rough experience years ago. Maybe the sound of that scaler makes your shoulders creep up to your ears. We hear you. That's exactly why our hygienists take a gentle, patient-centered approach every time. A professional cleaning — the technical term is prophylaxis — removes plaque and tartar that brushing and flossing just can't get on their own. Our hygienists use a mix of ultrasonic scalers and hand instruments to carefully clean above and below the gum line. The ultrasonic scaler works with high-frequency vibrations and a water stream to break up hardened deposits. Most patients are surprised at how comfortable it actually is. After scaling, we polish your teeth with a mildly abrasive paste to buff away surface stains and smooth things out. That smoothness isn't just for looks — it makes it tougher for plaque to grab hold between visits. Then we finish with a thorough flossing to hit every contact point. Sensitive teeth? Dental anxiety? We've got you covered with topical numbing gel and nitrous oxide. Our team also speaks Cantonese, Chinese, Tagalog, and Spanish on top of English — so if talking in your preferred language helps you relax, just let us know. Happy to do it.
This is one of the most important parts of a dental exam. It's also one of the most overlooked. The American Cancer Society estimates roughly 58,000 Americans will get diagnosed with oral or oropharyngeal cancer this year. But here's the thing — early detection changes everything. Catch it early, and the five-year survival rate tops 80%. Every comprehensive and periodic exam includes a visual and tactile oral cancer screening by Dr. Zhao. She examines the soft tissues throughout your mouth — tongue, floor of the mouth, palate, inner cheeks, lips, back of the throat — looking for unusual patches, lumps, sores, or color changes. She also feels the lymph nodes in your neck and jaw for anything abnormal. Takes just a few minutes. Completely painless. Risk factors include tobacco use, heavy alcohol consumption, HPV infection, and prolonged sun exposure (especially for lip cancer). Living in Tracy's San Joaquin Valley, where folks spend a ton of time outdoors in intense sun? We pay extra attention to the lips and surrounding skin during these screenings. If something looks suspicious, we'll walk you through next steps — maybe a biopsy, maybe a specialist referral. Most findings end up being nothing serious. But that peace of mind from regular screening? You can't put a price on it.
Waking up with jaw pain? Getting headaches that won't quit? Hearing a click or pop every time you open your mouth? You might be dealing with a temporomandibular joint disorder (TMD) — a condition affecting the hinge joint that connects your lower jaw to your skull. The National Institute of Dental and Craniofacial Research puts the number at over 10 million Americans affected. So no, you're not imagining it. TMJ/TMD evaluation is baked right into our comprehensive exam at the Tracy office. Dr. Zhao checks your jaw's range of motion, listens for joint sounds, palpates the muscles around your jaw, and looks at your bite alignment. Sometimes we'll pull in digital X-rays or 3D imaging to get a closer look at the joint itself. Treatment really depends on what's causing it. For a lot of patients, a custom-made occlusal splint (night guard) makes a huge difference — it stops teeth grinding and takes pressure off the joint. Other options include bite adjustments, physical therapy exercises, stress management, and sometimes restorative work to even out an unbalanced bite. And honestly? Tracy's commuter lifestyle — tons of residents driving to the Bay Area every day — creates stress-related clenching that we see all the time in our office.
Fluoride is one of the most proven tools in preventive dentistry. Full stop. It strengthens enamel and makes your teeth more resistant to the acid attacks that lead to cavities. Most toothpastes have it, and many water supplies do too — but a professional fluoride treatment delivers a much higher concentration right where it needs to go. The process takes just a few minutes. After your cleaning, we brush on a fluoride varnish — a thin, flavored coating — across all your tooth surfaces. It sticks to the enamel and keeps releasing fluoride for hours afterward. Quick. Painless. And honestly one of the most cost-effective things you can do to prevent decay. So who benefits most from fluoride treatments? Children and teens — their developing teeth are prime targets for cavities, patients dealing with dry mouth (from medication, our local climate, or medical conditions), adults who keep getting cavities despite good home care, anyone with exposed root surfaces from gum recession, orthodontic patients — those brackets create spots that are really tough to keep clean Given how dry Tracy gets and what that does to saliva, we frequently recommend fluoride treatments for adults who haven't had one since they were kids. Small step. Big payoff for keeping your teeth strong between visits.
If fluoride is your teeth’s shield, sealants are straight-up armor for the surfaces most likely to get cavities. They’re thin, BPA-free plastic coatings painted onto the chewing surfaces of your back teeth — molars and premolars — where deep grooves love to trap food and bacteria that brushing alone can miss. The whole thing is fast and totally painless. No drilling. No numbing. We clean the tooth, dry it, dab on a mild etching solution so the sealant bonds properly, rinse and dry again, paint on the sealant, then cure it with a special light. About a minute per tooth. Done. And sealants can hold up for five to ten years with normal care.
We usually recommend them for kids between ages 6 and 14 — those cavity-prone years when permanent molars are coming in. But adults can benefit too, as long as there’s no existing decay or fillings in those molars. Research in the Journal of the American Dental Association found that sealants cut cavity risk in treated teeth by nearly 80% within the first two years.
For Tracy families who want to give their kids the strongest possible start — sealants plus regular fluoride treatments plus solid home care creates a powerful triple defense against decay. It’s one of the smartest moves you can make for your child’s smile.
Living in the Central Valley means we deal with some specific stuff. The water in some parts of Tracy can be a bit hard, and the dry air in the summer can make your mouth dry. If you have a dry mouth, you are more likely to get cavities. We suggest drinking lots of water and maybe using a mouthwash that helps with moisture.
If you are wondering, “Who is the best dentist near me for my kids?”—we love seeing families! We try to make the office feel like a home so kids aren’t scared. We use simple words and show them all the cool tools we use.
We have been helping people in this community for years. We know the names of the local schools and the best places to get a taco on 11th Street. We aren’t a big corporate chain; we are your neighbors. We want to be the Dentist you actually enjoy visiting.
If you haven’t had a checkup in a while, there is no judgment here. We just want to help you get your health back on track. Our team is real friendly and we always explain what things cost before we start, so there are no surprises.
The standard recommendation is every six months for most healthy adults and children. Patients with a history of periodontal disease, diabetes, dry mouth, or other risk factors may benefit from visits every three to four months. Your dentist will tailor the schedule to your individual needs.
Tracy’s water supply from Central Valley groundwater has higher mineral content, which can actually benefit enamel strength. However, hard water can contribute to increased tartar buildup on teeth, making regular professional cleanings especially important for Tracy residents.
Call our office immediately — Dr. Zhao maintains a 24-hour emergency phone line. For a knocked-out tooth, handle it by the crown, rinse gently, and try to place it back in the socket or store it in milk. For severe toothaches, rinse with warm salt water and take over-the-counter pain relief. For abscesses or swelling, seek care right away as these can be serious infections.
The American Academy of Pediatric Dentistry recommends a child’s first dental visit by age one or within six months of their first tooth erupting, whichever comes first. These early visits help establish a baseline, check for early issues, and build comfort with the dental office.
Our office is located at 1431 N Tracy Blvd, Tracy, CA 95376, on one of Tracy’s main commercial corridors. We offer convenient on-site parking with ADA-accessible spaces.
Yes. Tracy’s hot, dry summers with temperatures of 95–105°F lead to dehydration, which reduces saliva production. Lower saliva flow increases risk for cavities, gum disease, and bad breath.
