Internal Bleaching Dubai

Internal bleaching in Dubai

Internal bleaching in Dubai is a specialized whitening treatment for a dark or discoloured tooth that has previously had root canal treatment. Unlike regular teeth whitening, which works on the outer surface of the teeth, internal bleaching targets staining from inside a non-vital tooth.

At Alma Polyclinic, the dentist first checks that the tooth is properly sealed, healthy, and free from infection. A small access is then made, and a professional bleaching agent is placed inside the tooth to gradually lighten the internal discoloration. The tooth is temporarily sealed and monitored over several days or weeks until the desired shade is achieved.

Whitening for Dark Root Canal Treated Teeth

Internal tooth bleaching can be a conservative option when one front tooth looks darker than the surrounding teeth after trauma or root canal treatment. Once the color improves, the bleaching material is removed and the tooth is permanently restored for a more natural and even smile.

This treatment is planned carefully to protect tooth structure while improving appearance. If you have a single dark tooth and want a natural-looking result, internal bleaching Dubai treatment at Alma Polyclinic may help restore harmony to your smile.

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 perborate 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.

Dental professionals typically perform these methods to ensure safety and effectiveness.

Teeth Bleaching Steps (Internal Tooth Bleaching)

  • Before internal tooth bleaching, the dentist must ensure that the tooth has undergone root canal treatment with a quality root canal technique. This is usually done with the help of images, and 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, fluorosis
  • Teeth discoloration as a result of genetic factors: congenital
    Erythropoietin porphyria, cystic fibrosis of the pancreas,
    hyperbilirubinemia (newborn jaundice), gametogenesis imperfecta,
    Ethnogenesis imperfect.
External causes of tooth discoloration

The leading causes of chromogenic are the consumption of some food sources such as winecoffeeteacarrotsorangeslicoricechocolate, 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 perborate 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

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, 30% hydrogen peroxide can be used as an alternative to 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 say 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.

Frequently Asked Questions

What is the best internal bleaching method?
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.
Is the procedure painful?
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.
