What is Internal Bleaching?

Internal bleaching is a type of bleaching that is performed on treated teeth. Unlike the external method, in which the bleaching agent is placed on the surface of a healthy, uncut tooth, in the internal method, the bleaching agent enters the cavity of the tooth.

Internal tooth whitening is an economical dental treatment that does not affect the shape of the teeth or their position in the dental arch.

Internal tooth bleaching is done to whiten the teeth from the inside and is often referred to as non-living tooth bleaching because it aims to whiten a tooth that has darkened due to damage or infection and is no longer living.

Sometimes, internal bleaching dental clinic experts believes that internal tooth whitening may be done before all-ceramic cosmetic restorations in order to improve the color of the tooth used as an abutment, which will allow light to pass more easily through the abutment and the final results of the cosmetic treatment. finally, recover.

Types of Internal Bleaching

Internal teeth bleaching, also known as internal tooth whitening, is a procedure used to whiten teeth that have darkened or become discolored due to trauma, root canal treatments, or other internal factors. The major types of internal teeth bleaching are:

  1. Walking Bleach Technique: This involves placing a bleaching agent, such as sodium perforate mixed with water or hydrogen peroxide, inside the tooth and sealing it with a temporary filling. The patient “walks” with the bleaching agent in place for a few days before it is removed and replaced as needed until the desired whitening is achieved​ ​.

  2. Thermocatalytic Bleaching: This method involves placing a bleaching agent inside the tooth and then applying heat to accelerate the bleaching process. This technique is less commonly used due to the potential risk of damaging the tooth structure from the heat​ .

  3. Inside/Outside Bleach Technique: A combination of internal and external bleaching methods. A bleaching agent is applied both inside the tooth and on its external surface. This is typically used for more extensive discoloration and may involve custom-made trays for home use .

These methods are typically performed by dental professionals to ensure safety and effectiveness.

Teeth Bleaching steps (Internal Tooth Bleaching)

  • Before internal tooth bleaching, the dentist must ensure that your tooth has undergone root canal treatment with a quality root canal technique.

    This is usually done with the help of images, radiography is done with X-rays. The dentist takes an intraoral X-ray of the area around the tooth to make sure there is no infection at the root of the tooth.

    Sometimes the tooth may have lost its life due to trauma and its color may have changed without undergoing endodontic treatment. In cases like this, root canal treatment should be the first step of treatment.

    If the tooth has had a successful endodontic treatment (no signs of infection), then we can proceed to internal bleaching or internal whitening of the tooth.

    The treatment begins with the removal of the white material that was used to fill the tooth, which is placed just above the root canal.

    Immediately after that, the root canal is filled with special materials, the purpose of which is to separate the root canal treatment from the whitening agent.

    As soon as this step is finished, we put the whitening agent into the space left above the crown of the tooth.


    Causes of Tooth Discoloration

    Internal causes of tooth discoloration
    • Discoloration of teeth as a result of taking some drugs (tetracycline)
    • Discoloration of teeth as a result of metabolic causes: dystrophic calcification, fluorous
    • Teeth discoloration as a result of genetic factors: congenital
      Erythropoietin porphyria, cystic fibrosis of the pancreas,
      hyperbilirubinemia (newborn jaundice), gametogenesis imperfect,
      Ethnogenesis imperfect.
    External causes of tooth discoloration

    The main causes of chromogenic are the consumption of some food sources such as wine, coffee, tea, carrots, oranges, licorice, chocolate, and tobacco from the habit or use of mouthwashes, or the presence of plaque on the surface of the teeth.

    Walking Bleaching Technique

    The first description of the bleaching technique is walking, with a combination of sodium perborate and distilled water.

    In this process, the compound remains in the pulp cavity for several days, and the access cavity is sealed (sealed) with temporary cement or glue.

    Internal bleaching dental clinic experts recommend using 30% hydrogen peroxide instead of distilled water to increase the bleaching effect of the composition.

    A combination of sodium perforate and water or hydrogen peroxide is still used today and has been described many times as a successful technique for bleaching the inside of a tooth crown

    What is bleaching?

    Application of bleaching agent

    Sodium perborate (tetrahydrate) combined with distilled water at a ratio of 2:1 (g/ml) is a suitable bleaching agent. If severe discoloration has occurred, 3% hydrogen peroxide can be used instead of water.

    The bleaching agent should be changed every 3 to 7 days. Successful bleaching results will be noticeable after 2 to 4 sessions, depending on the severity of the discoloration.

    Our internal bleaching dental clinic experts says that the patient should be taught to evaluate the tooth color on a daily basis and to visit the office if bleaching is acceptable to prevent over-whitening.

    Success Rate and Longevity of Internal Teeth Bleaching

    The success rate of various internal bleaching methods with different materials inside and outside the office is about 83 to 90 percent. That is, out of every 100 teeth that have undergone root canal treatment and are discolored, about 10 to 17 cases do not return to their natural tooth color with the internal tooth bleaching treatment.

    The durability of internal tooth whitening in some patients is lifelong. But in general, 35-50% of the teeth will still remain white about 5 years after the treatment, and for the rest, bleaching should be repeated.

    Repetition of internal bleaching requires trimming the previous restoration and creating a proper access hole. For this reason, part of the healthy dental tissue is cut. Therefore, in such cases, it is better to perform external bleaching first, and if the desired result is not achieved, then internal bleaching should be repeated.

    Temporary Tooth Filling

    Before applying the bleaching agent, the enamel margins of the cavity should be etched with 37% orthophosphoric acid to temporarily apply the filling agent.

    The mobile bleaching technique requires a flawless seal around the access cavity with composite resin or composer to ensure its effectiveness and avoid leakage of the bleaching agent into the oral cavity.

    If a temporary filling is used, it cannot be guaranteed. In addition, a good flood prevents re-contamination of the dentin with microorganisms and reduces the risk of new stains. It is often difficult to place the filler on the soft bleaching material.

    Among the various methods of internal tooth bleaching, the best method in terms of safety and effectiveness is the use of sodium perborate combined with distilled water or carbamide peroxide using the women’s step method. The internal bleaching method in the office with the application of heat has the highest probability of external root disintegration and is less recommended.

    Internal bleaching is generally not painful, but some patients might experience mild discomfort or sensitivity during or after the procedure. This sensitivity is usually temporary and can be managed with over-the-counter pain relievers and avoiding very hot or cold foods and drinks.
