Internal Tooth Bleaching

Internal tooth bleaching is a specialized dental procedure designed to whiten teeth that have become discolored from within, often due to trauma or previous root canal treatment.

What is Internal Tooth Bleaching?

Internal tooth bleaching, also known as non-vital bleaching, is a technique used to lighten the color of a tooth that has darkened due to the death of the tooth’s pulp or other internal factors.

Unlike traditional whitening methods that focus on the external surfaces of teeth, internal bleaching works from the inside out. It is particularly useful for teeth that have undergone root canal treatment and have become discolored over time.

How Does Internal Tooth Bleaching Work?

The internal bleaching procedure typically involves the following steps:

1. Initial Assessment: The dentist will conduct a thorough examination of the tooth, often using X-rays to assess the condition of the root and surrounding tissues. This step is crucial to ensure there are no underlying infections.
2. Accessing the Tooth: A small opening is made in the back of the tooth to access the pulp chamber. If the tooth has already been treated with a root canal, this step is relatively straightforward.
3. Placement of Bleaching Agent: A bleaching agent, usually a hydrogen peroxide or sodium perborate paste, is placed inside the tooth. This agent works to break down the discoloration from within.
4. Sealing the Tooth: The access hole is sealed with a temporary filling, and the bleaching agent is left in place for a specified period, which can range from a few days to a couple of weeks.
5. Evaluation and Repeat Treatment: After the designated time, the dentist will evaluate the tooth’s color. If the desired shade has not been achieved, the process can be repeated.

Benefits of Internal Tooth Bleaching

• Effective for Non-Vital Teeth: Internal bleaching is specifically designed for teeth that have lost vitality, making it a suitable option for those with darkened teeth post-root canal.
• Minimally Invasive: Compared to other cosmetic options like crowns or veneers, internal bleaching is less invasive and preserves more of the natural tooth structure.
• Quick Results: Many patients see significant improvement in tooth color after just one or two sessions, making it a time-efficient solution.
• Cost-Effective: Internal bleaching is generally more affordable than more extensive cosmetic treatments.

Considerations

While internal tooth bleaching is effective, it may not work for every case. Factors such as the severity of discoloration and the presence of any remaining infection can influence the outcome. 

In some instances, a combination of internal bleaching and restorative treatments, such as crowns, may be necessary to achieve the desired aesthetic result.

Aftercare Following Internal Bleaching

Post-treatment care is essential to maintain the results of internal bleaching. Patients are advised to:

• Avoid Staining Foods and Drinks: To prolong the effects of the bleaching, it’s best to limit consumption of coffee, tea, red wine, and other staining substances.
• Maintain Good Oral Hygiene: Regular brushing and flossing help keep the teeth and gums healthy, which is crucial after any dental procedure.
• Follow-Up Appointments: Regular check-ups with the dentist can help monitor the tooth’s condition and ensure that the bleaching results are maintained.

Risks and Considerations

While internal tooth bleaching is generally safe, there are some risks involved, including:

• Sensitivity: Some patients may experience increased sensitivity in the treated tooth, which usually subsides after a few days.
• Incomplete Results: In some cases, internal bleaching may not fully eliminate discoloration, necessitating additional treatments or alternative cosmetic options.
• Potential for Re-discoloration: Teeth that have undergone internal bleaching can still become discolored again due to factors like diet or oral hygiene practices.
