Due to the outbreak of COVID-19, we will be temporarily limiting our practice to emergency treatment only per ADA guidelines.

It was a difficult decision to make, but we felt it was in the best interest of our patients, staff, and the community at large.

We will be open with limited hours for emergency patients only. All regular treatment and preventive care will be resumed in the coming weeks as it is safe to do so.

Thank you for your patience and ongoing support!

Your Columbia River Dental Team.

Endodontic (Root Canal) Therapy


Endodontist patientendo3A "root canal," or endodontic therapy, is a procedure available to save a tooth that is infected and would otherwise require extraction. There are many reasons that teeth can become infected, including: cavities, previous large fillings, crowns, cracks, trauma and extreme wear.

Root canal therapy is needed when the nerve of a tooth is affected by decay or infection. In order to save the tooth, the pulp (nerve and blood supply), bacteria and any decay are removed, and the resulting space is filled with an inert material called gutta percha. After the tooth is healed, getting a crown is recommended, because the tooth will become brittle.
