New Methods of Bleaching Root-Canaled Teeth

Extraction of the tooth means removing the pulp of the tooth and turning it into a dead tooth. The materials used in tooth filling, as well as the structural changes of the tooth, can cause the color of root-canaled teeth to darken. In such cases, this problem can be solved by bleaching root-canaled teeth. As a dentist offering Newmarket teeth whitening at Leslie North Dental explains, the use of internal bleaching methods can improve the color of the teeth to some extent. As introduced at Dentistrynearme, which is a well-known dental directory, Leslie North Dental has an experienced and professional cosmetic dentist in Newmarket and the surrounding area. In these methods, the whitening agent is injected into your tooth through the cavity that is created. These materials can be removed in the same session or remain until the next session. The most common materials used in this method are hydrogen peroxide and sodium perborate. One of the possible side effects of this technique is tooth sensitivity or root erosion. If the bleaching method does not work well, the teeth can be whitened by changing the veneer.

All Kinds of Methods to Whiten Nerve Extraction Teeth

In order to have a correct understanding of bleaching root-canaled teeth, it is necessary first to know the types of bleaching and how they work. Bleaching is generally used for the following purposes:

Bleaching the External Surface

The outer surface of our teeth changes color due to contact with the food we consume. These substances can include all kinds of colored food, such as tea, coffee, soft drinks, or cigarettes. The effect of these substances on the teeth is gradual. The bleaching method dissolves these stains and whitens the outer surface of the tooth. For this reason, this method can be applied to the external surface of root-canaled teeth that do not have a coating.

Bleaching the Inner Surface

Sometimes, the color penetrates the tooth, and it is not possible to remove it with a toothbrush or scaling. Normal bleaching methods may not be sufficient for root-canaled teeth. For this reason, the following methods can be used for internal tooth bleaching. In all these methods, it is necessary first to create an access hole in the tooth. This hole is installed in such a way that it does not damage the repair material.

In-office Internal Bleaching:

In this method, a high-concentration bleaching agent is placed inside the cavity and remains in that area for some time. This may be done several times in one session or at intervals of several weeks. After removing the substance, the inside of the cavity is washed. This method will eventually cause the effect of whitening materials on the internal stains of the teeth. The common material for doing this method is hydrogen peroxide.

In Walking Internal Bleaching:

In this method, the dentist places the whitening material inside the tooth cavity and then bandages it. The patient returns after a week, and if needed, new materials are placed in his tooth cavity. This work continues until the desired color is reached. The most common bleaching agent used in this method is sodium perborate, which has a paste state and stays better in the cavity.

The Combination of the Above Two Methods:

In this method, the first method is first performed in the office, and then by placing the whitening agent in the cavity, it is bandaged on the tooth. This method is used for cases where a lot of color change is required.
