Non-vital teeth discoloration can occur due to various reasons such as trauma, root canal therapy, or internal resorption. These discolorations can cause embarrassment and affect the self-esteem of an individual. Internal bleaching is a treatment option that can effectively manage non-vital teeth discoloration.

Internal Bleaching

Internal bleaching is a conservative treatment option that involves the removal of the discolored dentin layer from the pulp chamber and replacing it with a bleaching agent. This treatment option is only suitable for non-vital teeth because vital teeth have an active blood supply that can cause irritation and damage to the pulp. Internal bleaching can be performed in a single visit or over a period of time.

Indications for Internal Bleaching

Internal bleaching is indicated for non-vital teeth that have discolored due to trauma, root canal therapy, or internal resorption. The treatment is suitable for teeth that have a good structural integrity and have no signs of active infection or decay. Patients who have good oral hygiene and have realistic expectations of the treatment outcomes are also good candidates for internal bleaching.

Contraindications for Internal Bleaching

Internal bleaching is contraindicated in teeth that have a poor structural integrity, signs of active infection or decay, and teeth with extensive restorations. The treatment is also not suitable for patients who have a history of allergic reactions to the bleaching agents and those with unrealistic expectations of the treatment outcomes.

Procedure for Internal Bleaching

The procedure for internal bleaching involves the following steps:

1)Access the pulp chamber: The first step is to access the pulp chamber by removing the existing restoration and any decayed or infected dentin.

2)Clean and shape the pulp chamber: The pulp chamber is then cleaned and shaped using endodontic files and irrigants.

3)Place the bleaching agent: A bleaching agent is placed in the pulp chamber and left in place for a specific period of time.

4)Remove the bleaching agent: The bleaching agent is then removed from the pulp chamber and the tooth is thoroughly rinsed.

5)Evaluate the results: The results are evaluated and the procedure may be repeated if necessary.

Post-Treatment Care

After internal bleaching, it is important to provide the patient with post-treatment care instructions. These may include avoiding dark-colored foods and drinks, maintaining good oral hygiene, and attending regular dental check-ups.

Conclusion

Internal bleaching is a conservative treatment option that can effectively manage non-vital teeth discoloration. The treatment is indicated for teeth with good structural integrity and no signs of active infection or decay. Patients who have realistic expectations of the treatment outcomes and good oral hygiene are good candidates for internal bleaching. Post-treatment care is essential for the success of the treatment.
