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.

About Us


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 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 Implants


Dental implants are artificial tooth roots that provide a permanent base for fixed, replacement teeth. This service is considered the optimum choice for replacing missing teeth.

Dental Implants are a popular and effective long-term solution for people who suffer from missing teeth, failing teeth, or chronic dental problems. This is a permanent service and can be expected, in most cases, to last for years.


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.

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. 

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.

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.

Success Stories




I love this office, everyone is super friendly and showed a genuine care for my well being. Not at all like some "factory " dental offices where they're heavy on sales versus patient care.



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.Like

Dr. King recently completed a Dental Implant to replace a molar. He was very thorough in clearly communicating to me the various options I had for dental repair. Having this implant has completely alleviated the dull pain I had experienced for years. I also recently, over the Holidays, had a previous dental crown break on a day when their office was closed. Dr. King responded to my phone call and had me meet him at his office for a temporary repair within the hour. He was able to complete the repair, determined the cause of the crown failure, and had me scheduled for a permanent crown replacement the following week. The Staff at Kennewick Family Smiles has provided excellent dental preventative care for my family for the last 20 years here in the Tri-Cities. The whole staff is very friendly and professional in all of their services. I highly recommend Dr. Isaac King and his Staff at Kennewick Family Smiles for all of your dental needs.
