Wisdom Teeth Removal
We specialize in the safe, efficient removal of impacted or problematic wisdom teeth. Our surgeons use advanced imaging and anesthesia techniques to ensure minimal discomfort and rapid recovery. Patients benefit from personalized pre-operative planning and post-operative care instructions tailored to their specific needs.
Dental Implants
Our dental implant procedures restore missing teeth with permanent, natural-looking solutions. We perform both single-tooth and full-arch implants using biocompatible materials. The process includes comprehensive evaluation, surgical placement, and long-term follow-up to ensure implant success and oral health.
Orthognathic Surgery
Corrective jaw surgery addresses misalignment issues affecting chewing, speech, and facial aesthetics. We collaborate with orthodontists to develop integrated treatment plans. The procedure improves both functional bite relationships and facial symmetry through precise surgical adjustments.
Bone Grafting
Bone grafting procedures prepare the jaw for dental implants by restoring lost bone volume. We use proven grafting materials and techniques to promote natural bone regeneration. This creates a stable foundation for successful implant placement and long-term oral health.
Facial Trauma Treatment
We provide emergency care for facial injuries including fractures, lacerations, and dental trauma. Treatment involves precise realignment of bone structures and stabilization techniques. Our surgeons work closely with hospital teams to ensure comprehensive recovery from traumatic injuries.

I have had an uncontrollable fear of dentists for most of my life. I fear I can't explain or control. I went to my dentist to find out i had to have a tooth removed. My fear of fears. for me it's not about the pain, as i have been in pain for a very long time. It's a control thing. I went to OMS today. From the second I walked in the door, I knew I had made the right choice. Absolutely fantastic experience, truly professional people, all around. I will probably never WANT to go back but I will never fear the process with OMS. truly a great experience my heartfelt thanks to all of you. John Murray.
