Indications And Side Effects Of Laser Teeth Whitening

A teeth whitening consists of a treatment that is within the dental specialty of aesthetics. Through this you get an improvement in the color of the smile in a simple and safe way. The procedure achieves a reduction in the hue of the teeth, in this way it is possible to achieve whiter and more natural teeth.

The laser tooth whitening is based on the application of hydrogen peroxide in the vestibular surface of the tooth. Peroxide releases oxygen atoms. This released oxygen is filtered through the tooth enamel and reaches the dentin, thus breaking down the pigment molecules. Therefore teeth whitening is a technique based on a chemical oxide-reduction process. The laser activates the gel so that it increases the oxidation process in hydrogen peroxide.

Side Effects Of Laser Teeth Whitening

Before performing any procedure, a good medical history of the patient must be performed. Analyzing the oral cavity and correcting all possible pathologies, as well as performing dental hygiene to remove plaque and be able to act on a sanitized mouth. Once the mouth is sanitized, the tooth whitening is done with laser. Laser teeth whitening is performed by a dental clinic specialist. It begins with an initial color take along with photographs of the chosen hue, so that you can visualize the color that was at the beginning of the treatment. 

Then the lips and cheeks are isolated by means of spacers. Next, the gums are protected by a light-curing gel. The whitening gel is placed on the vestibular surfaces of the teeth. The laser is applied for 15 minutes for the activation of the gel. Finally, all the remains of the bleaching gel are removed and the tissues are rehydrated.

WHAT ARE THE INDICATIONS OF LASER TEETH WHITENING?

Teeth whitening is usually indicated in cases of dental color nonconformity. In this way, the color is improved by reducing the tone of the dental white. This dental treatment is indicated when the mouth is healthy, that is, when there is no oral pathology.

WHAT SIDE EFFECTS CAN LASER TEETH WHITENING HAVE?

Tooth whitening is a treatment that, despite being conservative and generally giving satisfactory results, presents a series of risks which must be taken into account at the time of whitening.

  • Longevity and associated factors. The success of whitening in both vital and non-vital teeth is unpredictable. It depends on the patient’s habits.
  • Dental hypersensitivity post-operative. It may be related to the passage of hydrogen peroxide through enamel and dentin, which causes slight pulp irritation. For this reason, bleaching is contraindicated in patients with uncontrolled dental hypersensitivity.
  • Soft tissue sensitivity. It is related to the patient’s response to the concentration of peroxide solution. To reduce irritation, it is suggested to reduce the exposure time to the bleaching agent. If the problem persists, treatment should be suspended for one or two days while the gingival condition improves.
  • If the bleaching product is ingested it can cause gastric and throat irritation.
