Best Dental Experience in Kennewick
Our dentist's goal is to provide the best dental care in the Tri-Cities and give every patient the attention they deserve.


Your Kennewick Dentist
Between Dr. Sean Simper and the rest of our dental office, each patient is ensured first-rate care.
When our dentist Dr. Simper opened Southridge Dental in Kennewick, the goal was to create a dental experience unlike any other. He wanted his patients to feel as if they were visiting an old friend, not sitting in some sterile, unwelcoming office. Basically, his goal was to create a practice where he would want to be a patient!
Since then, Southridge Dental has compiled an incredibly talented dental team and superbly welcoming office staff that is there for their patients every step of the way! Reach out and schedule your appointment with us today!

Service Spotlight
Dental Implants
A dental implant (also known as an endosseous implant or fixture) is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, facial prosthesis or to act as an orthodontic anchor. Dental Implants are being used extensively in this day and age for tooth replacement.

From the moment you walk in to the moment you walk out, you will be treated so kindly! The receptionist is outgoing and friendly and will offer you treats like coffee, water, tea, juice and other assorted treats. The hygienist will offer you a choice of a warm neck roll, paraffin hand wax treatment, a warm blanket to name a few. Dr Simper will put you at ease and takes a lot in account regarding your individual treatment plan. You can tell that everyone who works here, loves their job!
