Kennewick Dentist - Voted #1 in Tri-Cities, WA 2019, 2020 & 2021
Our dentist's goal is to provide the best dental care in the Tri-Cities and give every patient the attention they deserve.

Best Dental Experience in Kennewick
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!

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.

Katie explained the entire process well and was awesome with the imaging and cleaning. Dr. Kayla was very nice and the ultimate pro in explaining some issues that I really didn't want to hear about my situation. You need three pros in your life. A great barber, a great auto mechanic and a great dentist. I've just move to the Tri-Cities and have found my great dentist. read less
