Millennium Smiles is a dental practice in Frisco, TX. Dr. Dunia Korous, D.D.S., FICOI, MICOI, treats implants, TMJ and jaw pain, sleep apnea and airway problems, and everyday family dentistry. Most new patients start with one exam and one 3D CBCT scan, so the plan covers teeth, jaw and airway together. We have two offices in Frisco: Lebanon Rd near The Star, and FM 423 at Main Street on the west side.

Dr. Korous has over 1,000 hours of advanced education in implants, TMJ, airway care, laser dentistry and complex treatment planning.
Jaw pain, broken teeth, gum issues and poor sleep often share the same root problems. We check the bite, jaw joints, airway and muscle function together, so treatment addresses what is driving the problem.
3D CBCT imaging, digital planning, lasers, same-day crowns and in-house 3D printing let us plan from what the scan shows. You see your own scan on screen before we recommend anything.
Massage chairs and warm towels are part of every visit. Laser dentistry can reduce the need for shots and drills in some treatments.

Smile makeover with veneers and crowns: patient testimonial
Dr. Dunia Korous, D.D.S., FICOI, MICOI, is the owner and lead dentist at Millennium Smiles. She is a general dentist with an advanced focus on dental implants, TMJ therapy, airway dentistry and sleep apnea care. She is a member of the Academy of General Dentistry and the American Academy of Cosmetic Dentistry.
She has completed over 1,000 hours of advanced education. Her training includes international implant surgery, TMJ evaluation under Dr. Steven Olmos, DDS, airway and tethered-tissue training with Dr. Soroush Zaghi, MD, laser and cosmetic dentistry, and orthodontic development for adults and children. She holds a neuroscience degree from UT Dallas.
Dr. Korous believes dentistry works when the full system is understood. Teeth, jaw position, airway size, muscle function and bite all matter.
Poor sleep, snoring and daytime fatigue are often linked to airway restriction. Care starts with a 3D CBCT airway evaluation.
We offer non-surgical options for mild to moderate sleep apnea and airway problems: oral appliances, skeletal expansion, laser therapy, myofunctional therapy and orthodontic support. If you cannot tolerate CPAP, an oral appliance may be an option, and your sleep study decides what fits. Adults and children can both benefit.
Jaw pain, headaches, clicking and bite problems often come from deeper functional issues. Dr. Korous checks the joints, muscles, bite and airway together. Treatment may include a custom TMJ orthotic, laser therapy to reduce inflammation, myofunctional therapy and orthodontic correction when needed. The goal is stable jaw function and long-term comfort, not only pain relief.
Dental implants replace missing teeth with a stable, long-term solution. Dr. Korous holds Fellowship and Mastership credentials from the International Congress of Oral Implantologists and advanced international surgical training. Implant cases are planned with 3D imaging of bone, bite and long-term stability.
Services include single implants, bone grafting and full-arch solutions like All-on-X.

“I came in suffering from severe TMJ, with my jaw locked for over a year and a half. I had previously tried Botox, muscle relaxers, pain medications, and steroids with little to no relief. … I arrived with a pain level of 10, but after just my first treatment, my pain dropped to a 2.”
