Internal Bleaching in Federal Way, WA

Internal bleaching is a dental procedure performed on a tooth that has undergone root canal treatment and has become discolored or stained from the inside. At First Smile Family Dental, internal bleaching aims to improve the tooth's appearance by lightening its color. Discoloration may occur due to factors such as the death of the tooth's nerve, internal bleeding, or the breakdown of dental materials used during the root canal procedure. Internal bleaching helps restore the tooth's natural color or improve its appearance.

The Procedure for Internal Bleaching

The dentist creates a small access hole in the tooth, usually through the back surface or the chewing surface, to gain access to the pulp chamber and the root canal filling. The dentist removes existing dental materials, such as root canal filling, to expose the discolored dentin within the tooth. A bleaching agent, often a hydrogen peroxide-based gel, is placed inside the tooth. The access hole is sealed with a temporary filling to prevent the bleaching agent from leaking out. The bleaching agent is left in the tooth for a specific period, typically around one to two weeks. During this time, the bleaching agent works to lighten the tooth's color.

After the waiting period, the temporary filling is removed, and the dentist evaluates the tooth's color. If necessary, additional bleaching sessions may be conducted until the desired results are achieved. Once the desired tooth color is achieved, a permanent filling or other restorative material is placed in the access hole to seal the tooth. Following internal bleaching, the dentist may recommend specific post-treatment care instructions. This may include avoiding certain foods and beverages that could stain the tooth, practicing good oral hygiene, and attending regular dental check-ups.

The Advantages of Internal Bleaching 

Improved Aesthetic Appearance 

The primary benefit of internal bleaching is improving the tooth's aesthetic appearance. Discolored or stained teeth can be a source of self-consciousness and affect a person's smile. Internal bleaching helps lighten the tooth's color from the inside, resulting in a more natural and pleasing appearance.

Conservative Approach 

Internal bleaching is a relatively conservative treatment option compared to other restorative procedures, such as dental veneers or crowns. It allows for the restoration of tooth color without the need for extensive tooth preparation or removal of healthy tooth structure.

Preserves Tooth Structure 

Since internal bleaching is performed on a non-vital tooth, it allows for preserving the remaining tooth structure. The procedure focuses on improving the appearance of the tooth without the need for more invasive treatments.

Minimally Invasive

Internal bleaching is a minimally invasive procedure that can be performed in the dental office. It typically does not involve significant discomfort or lengthy recovery periods. Patients can resume their normal activities shortly after the treatment.

With proper oral hygiene practices and regular dental care, the results of internal bleaching can be long-lasting. For the best dental care, visit First Smile Family Dental at 32717 1st Ave S., Suite 9, Federal Way, WA 98003, or call (253) 785-7323.
