Our Mission
Dr. Andrew Truong, DDS founded our practice on the belief that quality dental care and a positive patient experience should go hand in hand. Too many people put off dental visits because they’ve felt rushed, judged, or pressured in the past, and our mission is to change that. At Oil Hill Dental, every appointment is an opportunity to support your long-term oral health in an environment where you feel safe, heard, and respected. Our team brings expertise in family dentistry, cosmetic and restorative dentistry together under one shared philosophy: your health matters, your comfort matters, and the decisions about your care are always yours to make.

Our Dental Services
Crowns
Protecting a tooth that has been damaged by decay, injury, or wear is exactly what a dental crown is designed to do. Crowns fully cover the visible part of the tooth, restoring its strength, shape, and appearance all at once. With the right care, a crown can last for many years and keep your smile functioning like normal.
Our dentist uses digital scanning technology to take precise measurements with no messy impressions needed. At Oil Hill Dental, our goal is to protect your tooth and get you back to your daily routine as comfortably as possible. Each crown is custom-designed to match the surrounding teeth so the final result looks and feels completely natural.
Fillings
Leaving a cavity untreated allows decay to spread deeper into the tooth, often leading to more serious problems over time. Tooth-colored fillings stop that progression by removing the decay and sealing the tooth with a material that matches your natural smile. Modern composite fillings are durable, long-lasting, and far less noticeable than older metal options.
Scheduling a visit with our dentist at Oil Hill Dental sooner rather than later is the best way to keep small problems from becoming big ones. Digital scanners and dental lasers help us work with greater precision, making the process quicker and more comfortable at our practice. Treating a cavity early also means less of the natural tooth needs to be altered, preserving more of its original structure.
Cleanings
Professional cleanings remove built-up plaque and tartar that regular brushing and flossing simply cannot reach on their own. Staying current with routine visits is one of the greatest ways to catch potential issues early, before they become painful or require more involved treatment. Consistent preventive care is the most effective way to keep your oral health on track for years to come.
A dentist who makes you feel at ease makes it much easier to stick to a regular care routine, and that is exactly what our team at Oil Hill Dental strives to provide. We use CBCT 3D imaging and digital scanners to give every patient a thorough, accurate checkup alongside their cleaning. Patients of all ages and dental backgrounds are welcomed with the same level of care and respect at every appointment.
Emergencies
A knocked-out tooth, severe toothache, or broken filling can be frightening, but having a dental team you can count on makes a stressful situation much more manageable. Same-day care is available whenever possible because dental emergencies rarely happen at a convenient time. Acting quickly is one of the most important things you can do to protect your tooth and your overall oral health.
Our emergency dentist uses CBCT 3D imaging to get an accurate picture of the problem fast so treatment can begin without delays. Call our practice at 316-251-3565 and we will make room for you. Our team at Oil Hill Dental approaches every urgent situation with the same calm, compassionate care we bring to all of our patients, no matter the circumstances.
Same-Day Treatments
Waiting days or weeks for relief from a toothache or broken tooth is not something anyone should have to do. Same-day treatments make it possible to come in with a problem and leave with it resolved, whether that means a tooth extraction, a new filling, or another urgent procedure. Reducing the number of visits required is something we work hard to achieve for every patient.
Our emergency dentist at Oil Hill Dental is equipped with advanced in-house tools, including digital scanners and 3D printing, that eliminate the need to send work to an outside lab and speed up the entire process. Dental lasers allow our team to work with a level of precision that makes procedures more comfortable and recovery smoother. Every patient who comes in for same-day care leaves with a clear understanding of their treatment and what to expect going forward.
Invisalign
A straighter smile can do more than improve your appearance, as properly aligned teeth are also easier to clean and less prone to uneven wear over time. Invisalign offers a nearly invisible way to achieve that alignment using custom clear aligners that can be removed for eating, brushing, and flossing. No metal, no wires, and no major disruptions to daily life throughout treatment.
Our emergency dentist and full care team at Oil Hill Dental handle Invisalign right here at our practice, with no need for a separate orthodontic referral. Digital scanners make the process cleaner and more accurate from the very first appointment. Treatment is monitored closely at each visit to ensure your teeth are tracking properly and your results stay on course.
Meet the Doctor
With family roots between Augusta and El Dorado, Dr. Andrew Truong, DDS brings a personal investment to the care he provides that goes well beyond professional obligation. He chose to build his practice in El Dorado because this region has been part of his life long before his career began. Born and raised in Wichita and educated in Kansas, his entire life has unfolded within the state he calls home.
His approach to dentistry blends careful clinical thinking with a genuine interest in the people he treats, and that combination is evident in every appointment. In everyday life beyond caring for patients at Oil Hill Dental, he pursues hunting, mechanical projects, and a cattle ranching chapter he and a close friend are just beginning to write.

Frequently Asked Questions
How do I find a dentist that is actually a good fit for me?
The best indicator of a good dental fit is how you feel during and after your first visit. Pay attention to whether the team takes time to listen, explains things in plain language, and makes you feel comfortable raising concerns. A practice that respects your questions and never makes you feel rushed is one worth returning to.
Why does consistent dental care matter for my overall health?
The condition of your teeth and gums has a well-documented connection to broader health outcomes, including cardiovascular health and blood sugar regulation. Untreated gum disease, chronic tooth decay, and unaddressed oral infections can contribute to inflammation that extends beyond the mouth. Staying current with dental checkups is a proactive step toward protecting your health in a more comprehensive way.
What does good dental hygiene actually look like day to day?
Brushing twice daily with fluoride toothpaste, flossing once a day, staying hydrated, and limiting high-sugar foods and drinks are the core habits that support lasting oral health. Many patients are surprised to learn that technique matters as much as consistency, and our team is always happy to walk through the specifics during your visit. Small adjustments to a daily routine can have a meaningful impact on preventing tooth decay and gum disease over time.
At what point should children have their first dental visit?
Most dental professionals recommend bringing a child in around the time their first tooth appears, typically before their first birthday. Early visits allow the dentist to monitor development, identify any early concerns, and help children become familiar with the dental environment before any treatment is needed. Building comfort with dental care at a young age tends to carry forward in a meaningful way throughout a child’s life.
What is the difference between a routine cleaning and a deep cleaning?
A routine cleaning addresses plaque and tartar buildup on the surfaces of the teeth and just along the gumline, and is appropriate for patients with generally healthy gums. A deep cleaning goes further, targeting buildup below the gumline and along the root surfaces, and is typically recommended when there are signs of gum disease or significant inflammation. Our team will assess your gum health thoroughly during your exam and explain clearly which approach fits your current needs.
