Services
Dental Implants
Dental implants are durable, permanent solutions for missing teeth, restoring function and aesthetics. Our team uses advanced imaging and surgical techniques, including robotic assistance, to ensure precise placement. Patients benefit from improved confidence in eating, speaking, and smiling, with results designed to last decades.
TMJ Treatment
We address temporomandibular joint disorders using advanced diagnostics and therapies, including neuromuscular dentistry. Treatment alleviates pain, migraines, and mobility issues by correcting jaw alignment. Customized plans combine technology and expertise to restore comfort and function for long-term relief.
Cosmetic Dentistry
Our cosmetic services range from teeth whitening to full smile makeovers, focusing on aesthetics and function. Using veneers, bonding, and crowns, we correct discoloration, gaps, and misalignment. Treatments are tailored to enhance facial harmony while maintaining natural tooth structure.
Laser Dentistry
BIOLASE laser technology enables precise, comfortable treatments for gum disease, cavity removal, and root canals. This approach reduces bleeding, accelerates healing, and often eliminates the need for drills or scalpels, ensuring a gentler experience for patients.
Sedation Dentistry
We offer oral sedation, nitrous oxide, and NuCalm to ease anxiety during procedures. These options ensure patients remain relaxed and pain-free, making complex treatments like implants or extractions stress-free and accessible for all comfort levels.

This office was recommended to me by a friend as I was dealing with an abundance of issues since having braces as a teen. I was at a loss of what to do and was sure I was gonna lose all of my teeth that were affected, but thankfully to Dr George and all of the staff they were able to come up with a plan to save all my teeth quickly. Dr George does everything he can to make you as comfortable as possible during the whole process, Kathy, the one who handles all appointments and sets things up, really tries to answer every single question as thoroughly as possible for your understanding, the hygienist

I was going to come on and give a good review here and now that I read the others I'm glad I did. These doctors have treated me like family from DAY ONE. Everyone in the practice is extremely professional and friendly, the place is spotless. When I came in for my initial consultation I had been truly traumatized from my past experiences with dentists and my teeth were in what I believed to be disrepair. Dr. George and Dr. Mejia were so good at coming up with a plan that worked with my limited budget and kept every promise they made me. They have been extremely generous and I never would have

My husband had gone to advanced dentistry for a few years and was very happy with the services received. He hadn't gone in about 18 months and scheduled an appointment for a cleaning and dental checkup. After a consult, he was told our insurance is no longer accepted and was handed non itemized bill of $400 plus tax. Obviously upset, he asked for a breakdown of charges and was told "oh we don't do that". He put the charges on a credit card and signed for approximately $425. After a few days, he checked his credit card statement and found he had been charged over $490! For a

Horrible. Absolutely horrible. They will scam you into paying thousands for a simple procedure. Beware.

Advanced Dentistry has really changed my life for the better. For years I've suffered with TMJ. Migraines, jaw pain, neck, and back pain caused me to take pain meds on a regular basis. I went to other dentists and doctors that really didn't offer a solution - just more pain management. After seeing a neurologist who wanted to put me on blood pressure medicine and Botox injections, I found Advanced Dentistry. Yes, it was expensive, and yes, it was a more aggressive treatment than i had tried in the past, but it WORKED. Dr. Mejia, Dr. George, and the staff were with me every step of the

George,
I don't know how else to explain this to you. Nobody--i mean nobody!-- is gonna trust you when you overcharge, have an empty waiting room. refuse to provide samples of your work, demand full payment in advance and have all these reviews with the word "scammers" in them. Really, George. you overcharge because you went to all that school? Sorry, it's just not how things work.
