Under "bleaching" (German bleaching) is understood as a method by which discolored teeth are bleached by means of hydrogen peroxide. According to the latest research, bleaching, when properly used, is harmless to the dental substance. External discolorations caused by food and beverages can be removed by cleaning the teeth (air flow). But to correct tooth staining, teeth must be bleached.
Will be performed on discolored root canal treated teeth.
Procedure for internal bleaching: After removal of external discolouration (Professional tooth cleaning) as well as quality control of the root canal filling (OroTox-Test®, X-ray control), an access is created and the root canal is freed of all discoloring substances. This is followed by a weekly change of the insole until a color adaptation of the tooth to the adjacent teeth has occurred.
The causes of discoloration of vital teeth are manifold.
Procedure for external bleaching: After thorough diagnostics, first, coverings are removed by professional tooth cleaning. Any existing caries is removed to prevent leakage of bleach through the tooth. The bleach could otherwise cause inflammatory reactions of the tooth nerve.
The procedure we use can expect treatment successes of two to three years.
When teeth should not be bleached?
Extensive fillings or a heavily hollowed out tooth as well as enamel cracks or small fractures (small dentures) preclude bleaching therapy due to the increased risk of fractures.
Contact with amalgam restorations should be avoided as increased release of mercury has been detected after peroxide exposure. For this reason, we recommend removing all amalgam fillings before bleaching the teeth.
complications in internal bleaching:
- Dissolution (resorption) of the teeth in the area of the tooth necks
- Tapping sensitivity of the tooth
Complications of external bleaching:
- Sensitivity disorders of the teeth (hot, cold sensitivity of the teeth)
- In rare cases it can lead to gingivitis and necrosis of the gums (by etching)
Even with optimal course of treatment may lead to a renewed discoloration or the occurrence of side effects such as resorptions. If you have decided to do the bleaching, we recommend that you have this done in our practice. You can be sure that the procedure is appropriate.
