Choosing a dentist is one of the most personal health decisions a patient can make — and the clinician behind the care matters as much as the technology in the office. Dr. Dunia Korous is the owner and lead clinician of Millennium Smiles, where she brings together advanced clinical training, a root-cause diagnostic philosophy, and a deeply patient-centered approach to every treatment plan. With specialized expertise in dental implants, TMJ therapy, airway-focused dentistry, and sleep apnea care, Dr. Korous has built a practice in Frisco, TX that goes far beyond routine dental visits — one focused on long-term health, functional stability, and whole-patient wellness.
Education and Academic Foundation
Dr. Korous earned her Bachelor of Science in Neuroscience from the University of Texas at Dallas with Honors Distinction — a foundation in the biological sciences that continues to inform her understanding of the connections between the nervous system, airway function, and jaw mechanics. She went on to earn her Doctor of Dental Surgery (DDS) from the University of Texas Health Science Center at San Antonio, where she graduated with Distinction in Dental Education. Her academic background in neuroscience provides a unique clinical perspective, particularly in diagnosing and treating TMJ disorders, sleep-disordered breathing, and neuromuscular dysfunction.
Advanced Credentials and Continuing Education
Dr. Korous has completed more than 1,000 hours of continuing education — significantly exceeding dental licensure requirements — and holds several advanced designations that reflect her commitment to clinical excellence at the highest level.
- Mastership (MICOI): International Congress of Oral Implantology — the highest clinical achievement awarded by the organization, recognizing advanced competency in implant surgery and restoration
- Fellowship (FICOI): International Congress of Oral Implantology — awarded for demonstrated excellence in implant dentistry education and clinical application
- Fellowship (IALD): Institute for Advanced Laser Dentistry — advanced proficiency in laser-assisted procedures for soft tissue management, minimally invasive care, and accelerated healing
- Certified Phlebotomist: trained in venipuncture and biologic blood handling for in-house preparation of platelet-rich plasma (PRP) used in surgical and regenerative procedures
Her postgraduate education also includes extensive cosmetic dentistry and occlusion training through Spear Education and Clinical Master Series programs, advanced orthodontic and bite alignment coursework with Dr. Ed Lipski, DDS, and certification in Invisalign clear aligner therapy. This breadth of training allows Dr. Korous to approach complex cases with a multi-disciplinary perspective that few general dentists can offer.
Implant Dentistry Expertise
Dental implants are among the most technically demanding procedures in dentistry, and Dr. Korous has invested years of advanced training to deliver predictable, long-lasting results. Her Mastership and Fellowship credentials from the International Congress of Oral Implantology reflect proficiency in both the surgical and restorative phases of implant treatment — from single-tooth replacement to full-mouth rehabilitation and All-on-X full-arch solutions.
Dr. Korous has also completed hands-on international implant training in the Dominican Republic and Brazil, focusing on advanced surgical placement, bone grafting for complex cases, and techniques that prioritize bone stability, function, and long-term esthetic outcomes. Every implant case at Millennium Smiles is digitally planned using 3D CBCT imaging and supported by PRP therapy prepared in-house to enhance healing at the surgical site.
“An implant isn’t just a replacement tooth — it’s a foundation. When we plan around bone biology, occlusion, and long-term function, the results speak for themselves.” — Dr. Dunia Korous
TMJ Evaluation and Treatment
Dr. Korous has completed advanced TMJ evaluation and treatment training with Dr. Steven Olmos, DDS — a recognized authority in craniofacial pain and sleep-disordered breathing. Her approach to TMJ care goes well beyond a single appliance or symptom-based treatment. She evaluates the full picture — the joint, the muscles, the bite, and the airway — to identify the functional instabilities that drive jaw pain, headaches, clicking, locking, and bite dysfunction.
Treatment is tailored to each patient and may include custom TMJ appliance therapy, MLS laser therapy for inflammation and pain reduction, myofunctional therapy to retrain dysfunctional muscle patterns, orthodontic correction, and airway evaluation. By integrating these disciplines, Dr. Korous achieves long-term functional stability rather than temporary symptom relief.
Airway Dentistry, Sleep Apnea Care, and Myofunctional Therapy
Dr. Korous holds advanced training in airway-focused dentistry and Vivos protocols for the treatment and resolution of obstructive sleep apnea, with a focus on addressing airway deficiency and underlying anatomical causes. Through a combination of airway evaluation using CBCT imaging, skeletal expansion, oral appliance therapy, soft-palate laser treatment, myofunctional therapy, and orthodontic correction, she is able to effectively treat mild to moderate obstructive sleep apnea — significantly reducing or resolving symptoms such as snoring, daytime fatigue, jaw pain, and headaches. Many patients experience lasting airway improvement and stabilization without CPAP or surgery when treatment is completed and maintained appropriately.
Her expertise also extends to myofunctional therapy and tethered oral tissue management. Dr. Korous is Myobrace-trained for pediatric airway development and early orthodontic intervention, and she has completed advanced education in lip-tie and tongue-tie evaluation and release with Dr. Soroush Zaghi, MD, as well as international training in Italy focused on airway-centered management of tethered oral tissues. Her emphasis is always on correcting dysfunctional oral muscle patterns rather than masking symptoms — supporting proper jaw growth, facial development, and long-term airway health in both children and adults.
“Sleep apnea and TMJ disorders are not isolated problems — they share root causes in airway deficiency, skeletal development, and muscle function. When we treat all of these together, patients see real, lasting change.” — Dr. Dunia Korous
Laser Dentistry and Regenerative Care
As a Fellow of the Institute for Advanced Laser Dentistry (IALD), Dr. Korous integrates laser technology throughout her practice to deliver care that is less invasive, more comfortable, and faster to heal. She uses Solea laser technology to perform select hard- and soft-tissue procedures without injections, anesthesia, or medications — including removing small cavities completely drill-free and numb-free. She also performs soft-palate laser therapy to support airway stability and incorporates MLS laser therapy to reduce inflammation, accelerate healing, and relieve TMJ pain.
Dr. Korous also incorporates biologic and regenerative principles into surgical care. As a certified phlebotomist, she draws and centrifuges the patient’s own blood when clinically appropriate, using autologous biologic materials in extraction and surgical sites to support healing, reduce inflammation, and improve treatment outcomes.
Cosmetic and Restorative Excellence
Dr. Korous has completed advanced postgraduate education in cosmetic dentistry through Spear Education and Clinical Master Series programs, developing expertise in smile design, porcelain veneers, crowns, esthetic restorations, and the principles of occlusion and functional bite harmony. Her approach to cosmetic care is guided by the belief that esthetic excellence should never compromise long-term function, airway health, or biologic integrity. Every smile transformation at Millennium Smiles is planned with digital precision — evaluating tooth shape, proportions, gum levels, facial balance, and lip dynamics to achieve results that are both beautiful and sustainable.
A Root-Cause, Whole-Patient Philosophy
At the core of Dr. Korous’s practice is a holistic, systems-based approach to dentistry and airway care. Rather than treating symptoms in isolation, she focuses on identifying and addressing the underlying causes of dental and health concerns — including cavities, malocclusion, airway deficiency, TMJ dysfunction, and tongue-tie and lip-tie restrictions. She recognizes the strong connections between oral health and systemic inflammation, airway restriction and sleep quality, and jaw development and whole-body health.
Patients at Millennium Smiles are listened to first, examined comprehensively, and educated thoroughly. Treatment options are explained clearly so patients can make informed, empowered decisions about their care. Dr. Korous prioritizes long-term outcomes, predictability, patient education, and trust over short-term or symptom-only solutions.
