The Icon Dental Difference: Dentistry That Looks Further
We believe exceptional dentistry goes beyond creating beautiful smiles. Our dental practice takes a comprehensive, whole-body approach to oral health, recognizing the intricate connection between the mouth, airways, sleep, jaw function and overall well-being. Combining advanced technology, clinical expertise, and highly personalized care, we deliver a refined dental experience where every detail is intentional, every treatment has a purpose, and every patient is treated as a whole person.


Your 90-Minute New Patient Appointment
Your first visit to Icon Dental is a dedicated 90-minute appointment designed to give us a complete picture of your oral health and give you the clarity of a structured plan going forward.
We begin by listening. Before we look at a single tooth, we want to hear your history, your concerns, and your goals. From there, we conduct a full-mouth evaluation including digital X-rays, an oral cancer screening, a gum health assessment, and a careful evaluation of your bite, jaw alignment, and TMJ function. For patients with concerns about sleep quality or airway health, we incorporate screening for those as well.
You will leave with a clear picture of your oral health, a personalized treatment plan, and a team you feel comfortable calling your dental home. Patients consistently tell us it is the most thorough dental appointment they have ever had.

General and Preventive Dentistry Services We Offer
Comprehensive care means having access to everything you need under one roof, delivered by a team that understands how each service connects to your long-term health. Below is a full overview of the general and preventive dentistry services we provide at Icon Dental.
Comprehensive Check Ups / Dental Exams
Our comprehensive exams evaluate the full health of your mouth, including your teeth, gums, bite alignment, jaw function, soft tissue, and oral cancer risk. Digital X-rays are taken to identify concerns that are not visible during a visual examination, including cavities between teeth, bone loss, and structural issues beneath the surface.
We also assess TMJ function and bite alignment as a standard part of every exam, not as an add-on. Early detection is the foundation of preventive care. When we catch an issue early, treatment is almost always less invasive, less costly, and far easier on you. Learn more on our Comprehensive Check Ups / Dental Exams page.
Professional Dental Cleanings
Even the most diligent brushing and flossing routine cannot remove all of the plaque and tartar that accumulates over time. Professional dental cleanings performed by our experienced hygiene team remove that buildup thoroughly, protecting your gum health and reducing the low-grade systemic inflammation that untreated oral bacteria can contribute to.
For most patients, we recommend a professional cleaning every six months. Patients who are managing gum disease or have a higher risk of buildup may benefit from more frequent visits, and we will work with you to find the cadence that supports your long-term health most effectively. Our hygienists are known for being thorough, gentle, and genuinely invested in your care.
Gum Disease Screening and Treatment
Your gum health is the foundation of your oral health, and it is connected to your whole-body health in ways that are often underestimated. Gum disease has been linked to chronic systemic inflammation, and research continues to explore its relationship with cardiovascular health, blood sugar regulation, and other long-term health outcomes.
At every exam, we screen carefully for early signs of periodontal disease, including gum recession, pocket depth changes, and bone loss. Catching gum disease in its earliest stage, known as gingivitis, gives us the opportunity to address it before it progresses to more advanced periodontitis.
Scaling and Root Planing
When gum disease has moved beyond the early stage and standard cleaning is no longer sufficient, scaling and root planing is the most effective non-surgical intervention available. This deep-cleaning procedure goes below the gumline to remove the hardened plaque and tartar deposits that have accumulated on root surfaces, deposits that a routine cleaning simply cannot reach.
By clearing those bacterial deposits and smoothing the root surfaces, we give your gum tissue the environment it needs to heal and reattach properly. Most patients complete treatment over one or two appointments, typically with local anesthetic to keep the process comfortable throughout.
Consistent with our root-cause philosophy, scaling and root planing is not simply a reactive procedure. It is a targeted intervention that addresses the underlying bacterial environment driving gum disease, giving your oral health a genuine reset rather than a temporary fix.
Cavity Prevention
We believe that prevention is the key to maintaining a healthy smile and are committed to preventing cavities and preserving natural tooth structure through personalized preventative care, patient education, and comprehensive dental services to help every patient maintain a healthy, confident smile. Our philosophy here is to intervene early and thoughtfully rather than wait for problems to deepen.
Sealants: Available for both children and adults, sealants can be a simple, effective way to prevent cavities from forming in the first place. Dental sealants are thin, protective coatings placed on healthy teeth that shield the chewing surfaces of your back teeth from harmful, cavity-causing bacteria.
Fluoride: Fluoride treatments further strengthen enamel and help teeth resist the acid attacks that lead to decay over time. It works by stopping the growth of bacteria that cause cavities and strengthening the hard outer layer of the tooth.
Curodont™: A non-invasive, drill-free dental treatment designed to promote enamel regrowth, repair and reverse early-stage tooth decay and white spot lesions.
Laser Dentistry
Our laser dentistry technology allows us to perform a range of soft tissue procedures with greater precision and significantly less discomfort than traditional methods. Laser treatment supports bacterial reduction, helps treat gum tissue concerns, and promotes faster healing with minimal post-procedure sensitivity.
Less discomfort, faster recovery, and a gentler overall experience are outcomes we pursue with every technological investment we make. Learn more on our laser dentistry page.
Restorative Dentistry: Fillings, Crowns & Bridges
When a tooth is damaged, decayed, or structurally compromised, timely restoration is essential to prevent the problem from spreading and to preserve the function of surrounding teeth. Restorative dentistry gives you the best chance at long-lasting oral health. We can help restore your smile to full function by fixing damaged or decayed teeth. This improves your ability to eat, speak and chew.
Fillings: When a cavity is detected early, treatment is straightforward and conservative. We use tooth-colored composite material that restores the structure and function of the affected tooth without removing more healthy tissue than necessary.
Crowns: A dental crown can restore strength to a weakened tooth due to extensive decay or damage. At Icon Dental, we offer our signature same-day crown service using CEREC technology.
With CEREC, we design, mill, and deliver a custom porcelain crown in a single appointment. There is no temporary crown to manage, no second visit to schedule, and no prolonged period of sensitivity while you wait. We take a digital scan of your tooth, generate a precise 3D model, and deliver a finished restoration that fits beautifully and functions immediately.
For patients with busy schedules, same-day crown technology is one of the most practical conveniences modern dentistry offers. Learn more on our Same-Day Crowns page.
Bridges: Dental bridges are made to replace missing teeth and restore chewing function.
Advanced Technology, Built for Better Care
When Icon Dental was founded, the commitment was clear from the beginning: patients deserve access to the most advanced tools available. That commitment drives every technology investment we make.
We do not invest in technology for its own sake. We invest in it because it leads to better diagnoses, more comfortable procedures, and outcomes that our patients can see and feel.
Digital X-Rays
Our digital imaging system delivers high-clarity diagnostic images with significantly reduced radiation exposure. Results are immediate, allowing us to review findings with you in real time during your appointment.
Laser Dentistry
Precise, gentle, and effective for soft tissue treatments and bacterial reduction. Less discomfort and faster healing are the patient-facing benefits of this technology.
CEREC Same-Day Crowns
From digital scan to finished crown in a single visit. No temporaries, no second appointments, no waiting.
3D Digital Scanning
Used in Invisalign and orthodontic treatment planning, our 3D scanner eliminates the need for traditional impressions entirely. The process is quick, comfortable, and highly precise.
Every piece of technology in our office serves the same purpose: to give you a more accurate diagnosis, a more comfortable experience, and a better long-term outcome.

Frequently Asked Questions About General Dentistry in Denver
Our comprehensive exam goes well beyond a standard checkup. It includes a full-mouth evaluation of your teeth, gums, and soft tissue, digital X-rays, an oral cancer screening, and a careful assessment of your bite alignment and TMJ function. For patients with relevant concerns, we also incorporate airway and sleep screening. You will leave with a clear picture of your oral health and a personalized treatment plan that explains exactly what we recommend and why.
For most patients, we recommend a professional cleaning every six months. However, patients who are managing gum disease, have a higher rate of tartar buildup, or are working through an active treatment plan may benefit from more frequent visits. We will make a specific recommendation based on your individual oral health needs at your first appointment.
Because exceptional dentistry isn’t just about your teeth. It’s about your health, your comfort, and your quality of life.
Yes. We are actively welcoming new patients from Downtown Denver, LoDo, and across the greater Denver metro area. New patients receive a dedicated 90-minute appointment so we have the time to get to know you, conduct a thorough evaluation, and develop a care plan that fits your needs. You can schedule online or call us directly at (720) 645-2153.
Yes, and it is something we do routinely at Icon Dental. The structure of your jaw, tongue position, and airway alignment are all visible during a dental evaluation, and they are key indicators of sleep apnea risk. We ask about sleep quality, fatigue, and breathing patterns at every comprehensive exam. For patients who screen positive, we can discuss oral appliance therapy as a comfortable, effective option, and we coordinate with sleep medicine specialists when a formal diagnosis is needed.
Early gum disease, known as gingivitis, often presents with red, swollen, or tender gums that bleed during brushing or flossing. Many patients notice these signs and assume they are brushing too hard or that it is normal. It is not. Caught early, gingivitis is highly treatable and often reversible with professional care and improved home hygiene. Left unaddressed, it can progress to periodontitis, a more serious condition that affects the bone and tissue supporting your teeth. Regular exams allow us to detect and address gum disease before it reaches that stage.
This is a question we hear often, and it is an important one. Jaw tension, facial pain, chronic headaches, and even migraines can all be connected to bite misalignment, TMJ dysfunction, or nighttime clenching and grinding. Many patients have lived with these symptoms for years without anyone investigating a dental cause. At Icon Dental, TMJ and bite assessment are part of our standard comprehensive exam. If we identify a connection, we will explain it clearly and discuss your options, which may include bite adjustment, a custom oral appliance, or therapeutic Botox for clenching-related pain.
Absolutely, and this is one of the most important things we can share with our patients. Many of the most serious dental and oral health conditions, including early gum disease, cavities between teeth, oral cancer, and sleep apnea, develop without any pain in their early stages. By the time something hurts, the problem has usually progressed significantly. Preventive care is about catching those issues when they are small, treatable, and far less disruptive to your health and your schedule.
