Our Dental Services

Dental Implant Final Restorations

Protect your smile with the only true permanent solution to missing or damaged teeth. When a tooth is extracted or missing, an implant can often be placed. Once the implant is fused securely in the bone, a final series of appointments are made to create your permanent final restoration. Dr. Christensen will be able to determine if you are a candidate for implant procedures after a thorough examination.

Root Canal Therapy

Root canal therapy is a sequence of treatments for the infected pulp of a tooth which results in the elimination of infection and then protects the tooth from further infection.

Full Mouth Reconstruction

Full mouth reconstruction doesn’t just give you a great smile. Prior to creating final cosmetic restoration, the supporting structure of the jaw and tissue are restored to optimum health and function.

Fillings / Bonded Restorations

A bonded, tooth colored composite restoration is used to fix a tooth that is affected by cracks, decay, fractures and receding gum line. The affected portion of your tooth is removed and then filled with a composite filling.

Dental Sealants

Dental sealants are a preventive dental treatment, where a plastic material is placed in the pits and fissures or chewing surfaces of primary or permanent molar and premolar teeth to prevent decay.

A removable partial or complete denture may be made if you are missing some or all of your natural teeth. Often times implants can be incorporated with these appliances for optimum function. This is an option that can provide a functional bite and a natural looking smile as well as allowing you to eat more easily and speak clearly. All your options will be presented so you can make the best choice for your dental health.

Fixed Bridges

A bridge is an option to replace a missing tooth. The teeth adjacent to the missing tooth will be used and crowned as anchors connected to an artificial tooth where the tooth is missing. The entire bridge is then permanently cemented in the mouth as one piece. This helps prevent the teeth from shifting and restores function.

Tooth Extractions

Removing a tooth from its socket in the bone is a “tooth extraction”. With a tooth broken or damaged by decay, your dentist will try to repair it with a filling or a crown. In some cases the tooth, broken or damaged beyond repair, may require extraction.

A crown is a tooth shaped permanent restoration that covers the entire tooth, sometimes referred to as a “cap”.

A crown is custom made to restore a tooth to it’s original shape, color, and function.

A veneer is a custom made thin shell which covers the front and top edges of the tooth. Veneers are commonly used to improve the color and shape of existing teeth. For best cosmetic results they are made of porcelain and bonded directly to the tooth.
