Our expert surgeons offer a comprehensive range of oral surgeries, including wisdom teeth extraction, dental implants, oral pathology, and procedures to repair facial trauma.

Before starting a treatment plan for any of your oral or dental needs, our team offers a comprehensive consultation to study your mouth, teeth, and jaw to diagnose your condition and identify the best treatment options available to meet your needs.
Oral Pathology
Oral pathology includes diseases that affect your mouth and jaw. Our doctors diagnose and treat a wide range of oral pathologies, including oral cancer.

We want every patient to feel comfortable and confident while under our care. Our surgeons offer tried-and-tested anesthesia options such as nitrous oxide and IV sedation to ensure your comfort.

Wisdom Teeth
Contact us if your wisdom teeth are causing jaw pain, headaches, or other problems. We offer expert extraction procedures to protect and preserve your dental health.

A Dental computed tomography (CT) scan is an advanced form of imaging technology that makes it possible for your dentist to examine areas inside your mouth in 3D.

Dental Implants
Dental implants are an excellent replacement option for a missing tooth or teeth. Dental implants look like natural teeth, so no one will know you have a false tooth.


Our team of oral and maxillofacial surgeons has completed extensive training including dental school, medical programs, and surgical residencies. They have many years of experience in delivering outstanding patient care.

Yavik Kapadia

Jordie Nava

Friendly staff, good experience

Omar Torrentera

This was a great experience! All of the staff were professional and friendly. I had all of my questions answered during my appointment and there were no issues.


Very friendly staff, quick and to the the point. The front office, the doctors and assistants were very cool. If you’ve had an experience with other places that are pushy, disconnected, or unfriendly…I highly suggest you give them a try!


The visit went smoothly with knowledgeable and nice staff. The only small issue is that the nurse/medical assistant was explaining information about the surgical procedure too quickly. I know that they probably memorized everything because they give the same explanation repeatedly, but from the perspective of a new patient, it would be nice to clearly hear and understand possible complications and steps of the surgical procedure.

I was super super scared about getting my teeth pulled and they answered every question I had and made sure I was really comfortable with the procedure also everyone is so nice to me


My experience was good!
The only thing that bothered me a bit was that the assistant nurses-I believe that’s what they were, were joking around a lot. Not with me but with one another and I don’t know but that made me feel uncomfortable. They did not provide a professional atmosphere thus making me feel even more anxious because of how unprofessional they were being. They were squirting the water bottle to test it, laughing about that and making jokes etc. However, once the male doctor walked in he made me feel comfortable: his vibe and the way he proceeded and answered my questions was comforting.

The doctor that did my wisdom teeth surgery showed a lot of expertise before I went under.
