Techniques for dead teeth whitening

The whitening teeth has become a routine procedure for many people. This treatment is done in dental offices with equipment adequate, and also in home with over the counter products. A whitening undoubtedly requires the assistance of a dentist, she is cleaning a dead tooth. The decision on what procedure to use depends on the color and location of the tooth.

Dead teeth

A tooth dies when the pulp or nerve of the tooth becomes necrotic. The tooth may become necrotic due to a filling placed too close to a cavity that penetrates the nerve, or pinching of the latter. Devitalized tooth loses its water and blood flow, making it very brittle and prone to fade over time.

You can do a root canal to save the tooth, but this does nothing to preserve the color. The color change is intrinsic, that is corresponding to the inside of the tooth and will not improve with traditional methods used for whitening the tooth surface.

Ideal for dead teeth treatment

As teeth become brittle after a root canal, the ideal treatment is being restored with a core and a crown. A bolt and a core is for a posterior tooth, and is usually done with amalgam. The tooth is then prepared for a crown. In the front teeth, the core is only required if the tooth is broken to the point of having very little surface for supporting a crown.

Otherwise, a standard crown is normally sufficient. The tooth crown protects a fragile everywhere, and never darken the color because in most cases is made of porcelain.

Outpatient bleaching technique

The least invasive method for bleaching a vital tooth is non-ambulatory technique. A small hole is drilled in the lingual, or the inside of the tooth, and a cotton with a mixture of water and sodium perforate is placed. Then the hole is sealed with Cavity, a temporary soft padding. Achieving an effective whitening takes more than one session, in some cases many sessions of 40 minutes each.

After 40 minutes’ cavity and cotton piece is removed. Cavity is placed over the opening to seal until the next session. In subsequent visits to the dentist, you should assess the success of whitening and re-performed if the patient is satisfied.

Bleaching technique thermo-catalytic

The thermo-catalytic bleaching is more invasive than outpatient. The approach is similar. a hole in the inside of the tooth is drilled but bleached material is much stronger and somewhat caustic.

The Super hydrogen peroxide are placed on the tooth in a cotton ball and the hole is sealed. Heat is applied to the tooth for 30 to 40 minutes. Cavity then removed and the piece of cotton, and reseal the tooth until the next visit. The sessions are scheduled regularly to evaluate the results and reapply as long as necessary. Although this method is faster by strong materials used, it is also riskier. The Super oxeye is a powerful bleach and may cause irritation to external tissues, and also inside the tooth.
