About Us
Our Services


Routine Exams and Cleanings


         You and your family should clean and check up your teeth in a dental office every six months to prevent and treat oral cancer and diseases.  If you have moderate to severe gum diseases, you should clean and check up your teeth every three months.  We also treat child patients from three years or older. 

Crowns, Bridges, Veneers, Lumineers


      When your tooth is broken, damaged, missing, or in poor condition with dark color or large fillings, you should protect it from further damage by using a crown, bridge, and/or veneer.  Veneers and Lumineers are great for esthetic looks.

Fillings & Root Canal Therapy


     When your tooth has a cavity, a hole, or is broken, you should fill it as soon as possible to prevent any further damage, including root canal therapy, post and core, crown or extraction.  We do RCT on all teeth with 3D digital x ray technology.

Removable Dentures


    The most cost effective solution to replace missing teeth is a removable denture.  You can chew better with implant-supported overdentures, and we can help you in our offices.



     Your own, natural teeth are always better than implants.  But, when you have a missing tooth or more, implants are one the the best treatments available.  We do complete implants in our offices.  We use 3D digital x ray to place a  precise 3D implant.  Our implants are 100% made in the USA with five year warranty.

Teeth extraction


     Broken teeth and cavities lead to infection, pain, and bad smells, and might need removal.  We also extract impact wisdom teeth with over 20 year experience.

Emergency Dentistry


   If you have a toothache, you should contact us as soon as possible to stop your pain and completely treat the problem.

Teeth Whitening


    The first step of brighten your smile is bleaching your teeth.  It is cost effective and works well for many patients.

Invisalign, Clear Orthodontic Treatment
We are a Certified Invisalign Provider For Teens And Adults


Majority of orthodontic patients can be treated with Invisalign.  The main advantage of Invisalign treatment --  you can floss and brush your teeth as normal!  Therefore, Invisalign is a great way to prevent cavities during and after orthodontic treatment, especially for children.
