Meet the Doctors

Kelvin Tse, DDS

Complex interdisciplinary dental cases are Dr. Tse’s specialty. He works with other dental specialists such as Orthodontists and Periodontists to create functional and long lasting aesthetic restorations. He has recently introduced Minimally Invasive Veneers (MIV) to his patients. This is leading edge technology in which conservative or no tooth preparation is required to place veneers over teeth and create a healthy and beautiful smile.

If he is not at the office, Dr. Tse is with his family or lending a hand to others.

Kids Love It Here!

Our fun, relaxed environment and theme gets kids excited about their dental care. While most adults would agree with the importance of protecting their adult teeth, many overlook the developmental significance of the primary dentition, or "baby teeth." Most pediatric dental patients have both adult and baby teeth, or mixed dentition, and a pediatric dental specialist understands proper care of both.

Adult Dentistry

From toddlers to the elderly, our skilled dental team is familiar with the unique needs of every patient, no matter their age. Our goal is to help develop great oral habits that will last them a lifetime.

Join us today and discover how our practice can help treat your entire family.

Orthodontics For All Ages

A beautifully-aligned natural smile can be obtained both with traditional metal braces and other more subtle options like Invisalign® "invisible" orthodontics.

Traditional Braces with Colored Bands

Traditional metal braces are the most common type of braces and are more comfortable today than ever before. Made of high-grade stainless steel, metal braces straighten your teeth using metal brackets and archwires. With metal braces, you have the option of adding colored elastics (rubber bands) for a more unique and colorful smile.

The Damon System of Self Ligating Braces

Self-ligating braces use a specialized clip in place of elastics to help the archwire guide teeth into place. These clips help reduce the amount of pressure being placed on the tooth and require fewer adjustments because there are no elastics to replace. A shorter treatment time is experienced by a high percentage of patients. The Damon System facilitates healthy tooth movement with complete control. By combining passive self-ligation and high-tech archwires, we can minimize discomfort and create beautiful smiles that last a lifetime!

Insignia 100% Custom Bracketing System

Your smile is unique, so why shouldn’t your treatment be, too? Insignia is a truly customized approach to orthodontic treatment. Dr. Fenderson is among the select few Orthodontists who are certified to use the high-tech Insignia system that produces faster, higher quality results, often reducing treatment by around 25%.
