A place where kindness, clear communication, and modern, comprehensive dentistry come together.
Trusting your dental provider shouldn’t be a challenge, but for many people, it is. Dr. Andrew Truong, DDS is dedicated to changing that. Oil Hill Dental is the kind of place where patients don’t just get their teeth cleaned, they actually look forward to coming back to see our dentist in El Dorado, KS. Our modern hometown dental practice offers a full range of dental services, including routine dental cleanings, fillings, dental implants, Invisalign, and cosmetic dentistry, all in one place. New patients and those who’ve been putting off care for a while are met with a warm, judgment-free environment where your comfort always comes first.

Dr. Andrew Truong, DDS started Oil Hill Dental with one clear goal: to be the dentist that people feel truly good about visiting. That means treating every patient with respect, never applying pressure, and making sure you fully understand your options before any decisions are made. Good oral health isn’t just about avoiding tooth decay or gum disease, it’s about feeling confident in your smile and your overall well-being. From your very first dental appointment, our team works hard to make sure you feel seen, heard, and cared for. The cookies and fresh coffee in the waiting room are a small but sincere reflection of how seriously our practice takes the patient experience.

Here is a closer look at what Oil Hill Dental is built around and why it matters to the patients we serve.
Routine visits focused on early detection, prevention, and keeping your smile healthy and beautiful year after year.
When possible, we offer quick and efficient same-day care to reduce repeat visits and make you feel better faster.
Fast, compassionate care for dental pain, broken teeth, or unexpected issues when you need help right away.
Custom-fitted full and partial dentures designed to restore comfort, function, and confidence.
Discreet orthodontic option that straightens teeth comfortably without traditional metal braces.
Durable restorations that repair damaged teeth or replace missing ones while blending naturally with your smile.
A long-term solution for missing or damaged teeth that looks, feels, and functions like a natural tooth.
Thin, custom shells that enhance the overall look of your smile by improving shape, color, and alignment.
Tooth-colored fillings that repair cavities while preserving the natural look of your teeth.
A damaged or weakened tooth doesn’t have to mean losing it. Crowns are custom-fitted caps that cover a tooth completely, restoring its shape, strength, and appearance. Our dentist uses advanced digital scanners and 3D imaging to make sure every crown fits precisely and looks natural alongside your other teeth.
Many people assume getting a crown takes multiple long visits and a lot of discomfort. That’s not always the case. Same-day treatment options help reduce unnecessary trips back to our practice.
Here’s what the crown process often involves:
Waiting too long to address a cracked or decayed tooth often leads to bigger problems. A crown placed at the right time can prevent the need for an extraction later. It shields what remains from further wear, pressure, and bacteria.
Signs it may be time to ask about a crown:
Oil Hill Dental makes it straightforward to get started, even if you’re unsure about what you need. Our team is approachable, patient, and ready to talk through your situation without making it feel overwhelming. Reach out today and our team will point you in the right direction.
Cavities are one of the most common dental problems people face, but treating them doesn’t have to change the way your smile looks. Tooth-colored fillings repair decayed areas using a material that blends seamlessly with your natural tooth. No dark metal, no obvious patch.
Our dentist matches the filling shade to your existing tooth color, so the result looks like nothing was ever there.
Metal amalgam fillings were the standard for decades, but tooth-colored alternatives have changed what patients can expect from restorative care. Beyond appearance, the material bonds directly to the tooth, which means less healthy structure needs to be removed during prep.
Here’s what makes tooth-colored fillings a preferred choice:
A small cavity treated early stays a small problem. Left alone, decay spreads deeper into the tooth, eventually reaching the nerve. At that point, the treatment required becomes far more involved than a simple filling.
Catching decay early keeps your options straightforward. Our dentist takes a patient-centered approach. No pressure, just honest information so you can make the right call for your health.
Watch for these early warning signs:
At Oil Hill Dental, every patient is treated with care and respect from the moment they walk in. Our practice is built around making people feel comfortable, not rushed or judged. That same standard applies to every filling appointment, start to finish.
Routine cleanings do more than polish your teeth. They remove built-up tartar that regular brushing can’t reach, give our dentist a chance to spot early signs of decay or gum disease, and set the foundation for lasting oral health. Skipping them often means catching problems later, when treatment is more involved.
Putting off a cleaning might seem harmless, but plaque hardens into tartar quickly. Tartar can only be removed by a dental professional. Over time, buildup along the gumline leads to inflammation, gum disease, and eventual tooth loss.
A twice-yearly cleaning catches these issues before they escalate:
Consistent preventive care is one of the most powerful things you can do for your long-term health. Patients who maintain regular cleanings tend to need far fewer restorative procedures over their lifetime. That means less time in the chair overall.
Good long-term oral health starts with:
Oil Hill Dental is proud to serve El Dorado and the surrounding communities as a practice patients can count on year after year. Routine visits are a big part of how we build lasting relationships with the people we care for. We look forward to seeing you at your next appointment.
Dental emergencies rarely give any warning. A cracked tooth, sudden severe pain, or a knocked-out tooth can happen to anyone at any time. Knowing where to turn and acting fast makes a real difference in the outcome. Our dentist is ready to see urgent cases as quickly as possible, often the same day you call.
Don’t wait hoping it resolves on its own. Most dental emergencies get worse without prompt care.
Not every urgent situation looks the same. Some patients come in with throbbing pain from an abscess. Others arrive with a broken tooth from an unexpected fall or injury. Our dentist takes time to assess each situation accurately using advanced tools like CBCT 3D imaging and dental lasers for precise, comfortable treatment.
Situations that call for an emergency visit include:
Delaying emergency care often turns a fixable problem into a much larger one. An untreated infection can spread. A cracked tooth left alone may eventually require extraction. Acting quickly gives our dentist the best chance to save the tooth and prevent complications down the road.
Prompt care leads to better outcomes:
Dental pain is never something to wait out. We prioritize urgent cases so you’re not left in pain longer than necessary. The sooner you call Oil Hill Dental at 316-251-3565, the sooner our team can assess what’s happening and get you feeling better.
Multiple dental appointments for a single problem can be frustrating, especially if you’re already uncomfortable. Same-day treatments let our dentist address your needs in one visit. Less time away from work, less time in the waiting room, and faster relief.
If you come in with pain, our goal is to take care of it that day whenever possible, including removing a tooth or placing a filling.
Traditional dental treatment often means coming in for a consultation, scheduling a follow-up, then waiting days or weeks for the actual procedure. Same-day care cuts that process down significantly. Our in-house technology, including digital scanners, 3D printing, and dental lasers, makes it possible to complete accurate, precise work without sending anything to an outside lab.
Here’s how same-day care differs:
Waiting in pain is one of the most common complaints patients have about dental care. Same-day treatment removes that gap between identifying a problem and actually fixing it. Our dentist takes the time to keep you informed and comfortable throughout the visit, even in time-sensitive situations.
The impact of faster care is real:
Patients who visit Oil Hill Dental for same-day care leave knowing exactly what was done and what comes next. Our team keeps you informed and at ease, no matter how quickly things need to move. That kind of confidence is something every patient deserves walking out the door.
Straightening teeth used to mean years of metal brackets, wires, and adjustments. Clear aligner technology changed that entirely. Invisalign uses a series of custom-fitted, removable trays to gradually shift teeth into position, with no metal, no tightening appointments, and no need to hide your smile during treatment.
Our dentist uses digital scanners to map your teeth precisely, making the fitting process comfortable and mess-free at the very first visit.
A lot of patients assume Invisalign is only for minor cosmetic corrections, or that it takes longer than traditional braces. Neither is always true. Invisalign treats a wide range of alignment concerns, and treatment timelines vary based on the individual case, not the method.
Facts worth knowing before ruling it out:
Some patients avoid pursuing orthodontic care because they don’t want the look of metal braces as an adult. Others worry about the commitment involved. Our dentist walks through every option clearly, answers questions honestly, and never pressures patients toward a decision.
Common concerns we help patients work through:
Straighter teeth do more than look good. Proper alignment affects how comfortably you bite, how clearly you speak, and how evenly your teeth wear over time. Contact our team at Oil Hill Dental and let’s talk about what Invisalign could do for you.

Dr. Andrew Truong, DDS grew up in Wichita, Kansas and earned his undergraduate degree in Ecological Biology at the University of Kansas before completing his Doctor of Dental Surgery at the University of Missouri-Kansas City. His family’s farm has kept him deeply rooted in this part of the state, and he has spent years building meaningful relationships within the communities he serves.
For Dr. Truong, dentistry is the ideal combination of science, technology, artistry, and hands-on problem solving, and that passion shows in every patient interaction. Outside the practice, he enjoys hiking, photography, snowboarding, and camping, and he is working toward starting a small cattle herd with a close friend. He shares his home with his fiancée and their two cats.

Most patients benefit from visiting their dental provider every six months for routine checkups and teeth cleaning. Those managing gum disease, a history of tooth decay, or other ongoing oral health concerns may need to come in more frequently. Our dentist will help you determine a schedule that fits your specific needs.
A dental emergency includes situations like a knocked-out tooth, severe tooth pain, a broken or cracked tooth, or sudden swelling in the mouth or jaw. If you’re experiencing any of these, contact our practice as soon as possible rather than waiting to see if it improves on its own. Our team provides emergency dental care to get you effective treatment quickly.
Our practice welcomes patients across a wide range of ages, making it easy for the whole family to receive care in one place. Seeing the same dental team over time helps track long-term oral health patterns and builds a relationship grounded in familiarity and trust. It also makes scheduling more convenient when multiple family members need appointments.
A routine cleaning removes plaque and tartar buildup from the surface of your teeth and along the gumline. If there are signs of gum disease or significant buildup below the gumline, a deep cleaning, also known as scaling and root planing, may be the more appropriate option. Our dentist will assess your gum health during your exam and clearly explain which approach is recommended and why.
We work with many dental insurance plans and are happy to help you understand your benefits before treatment.
You’re not alone. Our team takes a gentle, respectful approach and focuses on helping patients feel comfortable, informed, and at ease.
When possible, we offer same-day treatment to minimize extra visits and get you back to feeling your best sooner.
We offer comprehensive care under one roof, including preventive, restorative, cosmetic, orthodontic, and implant dentistry.
