Welcome to Kennewick Family Smiles

Dr. Isaac King


I have had the pleasure of serving the greater Columbia Basin for the last 10 years.  Continually earning your trust is one of the greatest joys I take pride in this wonderful profession.  






I have been working with this practice since June 2013 and only just recently can say that I have met everyone.  I feel blessed to work for an office that feels more like a community. It is wonderful to work together with patients who care for their oral health and are willing to learn about advances in dentistry.  I look forward to working together on improving your periodontal health and how it can affect your overall health.  


Front Desk Coordinator


For the past 6 years, I  have had the pleasure of helping out wonderful patients with their dental scheduling needs and of course navigating the world of dental insurance.   Please contact our office to schedule an appointment or if you just have questions.  




Lead Dental Assistant


My journey started in 1989 here with Dr. Johnson. I've made so many friends here throughout my 28 years.  I love to help people feel good about their teeth and their dental visits.  I truly can call you friends and not patients.  I am so excited to start a new journey with Dr. King as we will be expanding our services to our friends and helping them with all of their oral needs.  I cannot wait to learn and grow more in the industry I love.



General & Family Dentistry


Dr. Isaac King and our dental team love to serve patients of all ages. Kennewick Family Smiles works tirelessly to ensure each of your family members gets the best care possible. 

Dental Fillings


When a patient has a cavity, Dr. Isaac King may place a dental filling.  Our dentist will remove the decayed part of your tooth and fill the area with a filling material. Composite dental filling materials can also be used to repair teeth that are cracked, chipped, broken, or worn down.

Dental Checkups, Exams & Cleanings

Prevention is key to a healthy mouth and smile. We recommend that you and your family have a professional teeth cleaning at least once every six months. This appointment includes a teeth cleaning, fluoride, a dental exam, and X-rays. Teeth cleaning appointments are important to help prevent cavities and to catch dental issues early while they are easiest to treat.

Dental Crowns


If your tooth needs its shape, size, strength, and appearance improved or restored, a dental crown may be the best option.  A crown is a tooth-shaped covering that is placed over your tooth.  There are a variety of crown materials and Dr. King will work with you to use the best option that meets your needs and expectations.

Root Canal Treatment


Dental pulp is the soft area at the center of a tooth where the veins, nerves, and connective tissues are located. If the dental pulp becomes damaged or infected, root canal therapy is indicated.  The Root canal therapy is the process by which our dentist removes the decayed pulp, bacteria, and debris from a tooth. Sometimes, there are no signs that a root canal is needed. Kennewick Family Smiles strives to make your root canal experience as comfortable as possible. 

Tooth Extraction


If you need a tooth extraction, it is essential to find a dentist with years of experience.  Kennewick Family Smiles has a variety of options to ensure an uncomplicated process. We offer nitrous oxide, oral sedation, and provide a no rush atmosphere. You're in good hands with Dr. King.

Dr. King and his staff provide exceptional services. From the moment you walk in, you feel the caring personal warmth. In fact, Dr. King has personally called us to check on our dental needs. He is the most personable and skilled dentist we have entrusted our dental needs to. Great service...check it out yourself.

I have been to a lot of dentists but this place is by far the BEST!! I love everyone there they truly care about their patients... I have never had a dentist's office call after having teeth pulled to check on you! I have a huge fear and they were so patient with me...Again they are the best!!

Love Kennewick family smiles. Dr. King and Sherry and all the ladies that work for us do an excellent job. When I thought my crown wasn’t sitting right he took me in the very next day and was able to get it fixed and taken care of and they did it all with cheerful and professional attitudes wouldn’t go any other place.
