Our Services

Preventative Care


Taking good care of your teeth goes beyond daily brushing and flossing. We now know that there is a very strong connection between your oral health and whole body health. By keeping your teeth and gums healthy, not only can future dental problems often be prevented but can also aid in good overall health.

Pediatric Dentistry


The essence of what Dr. Chee and her team love about pediatric dentistry is helping children enjoy their dental visits by infusing the office with fun, laughter, and comfort. She welcomes children of all ages, and encourages you to bring your child in after they turn one. The key to a healthy mouth is establishing a good oral hygiene regimen early in a child’s life. 

Restorative Dentistry


Dr. Chee practices restorative dentistry, encompassing preventative treatment, crowns, bridges, bonded restorations, onlays and inlays, and advanced restorations including dental implant restorations and dentures. Restorative dentistry involves the diagnosis, management and restoration of the functional and aesthetic requirements of each individual. 

Cosmetic Dentistry


Creating a beautiful smile and helping you to maintain that smile is what Dr. Chee and her staff love to do. There are several aspects of cosmetic dentistry, including whitening, veneers, bonding, crowns, and more. Ask Dr. Chee and she’ll help you understand what is possible and determine the next steps to getting the smile you’ve always wanted!
