Services
Teeth Whitening
Our teeth whitening services use advanced in-office and custom tray methods to brighten smiles safely and effectively. Patients achieve noticeable results in one visit or through at-home kits. Treatments are tailored to individual sensitivity levels and lifestyle needs.
Dental Implants
We provide full-service dental implants, from consultation to restoration, using nickel-titanium posts and bone grafting when needed. Our team ensures durable, natural-looking replacements that restore function and aesthetics with long-term success.
Clear Aligners
ClearCorrect aligners offer a discreet, comfortable alternative to braces. Custom-made trays gradually straighten teeth without metal brackets, allowing easy oral hygiene and flexibility for eating and special events.
Porcelain Veneers
Veneers correct chipped, stained, or misshapen teeth with ultra-thin porcelain shells. Our process includes personalized smile design and precise bonding for a natural, long-lasting transformation that enhances confidence.
Periodontal Treatment
We treat gingivitis and periodontitis through deep cleanings and maintenance plans. Our approach prevents tooth loss, addresses systemic health links, and includes patient education on home care and risk factor management.

This is an excellent Dentist Office! I've come for 3 cleanings so far and have yet to be disappointed. The staff are very responsible, professional, and friendly. My teeth are in great condition and I leave feeling refreshed after every cleaning. I am also particularly impressed with the general hygiene and use of technology at this office. The attention to detail shows just how dedicated Dr. Assadian and his staff are to their craft and patients. I would highly recommend this dentist office to anyone.

First off I had an emergency situation where there was a large chip that came out of my tooth. Originally because my insurance was just kicking in they weren't gonna be able to take me until May however Sanae pulled some strings to make it possible and got me in. Dr. Assasian did a phenomenal job and it was completely pain-free. Unfortunately I needed to get a crown however even though this is my first experience he made it possible for me to get through it in one piece with no pain and really talk me through the process. I can't recommend this place enough. And everyone is so kind. Sanae an office is awesome too! Thank you! Cheers!
