Teeth Bleaching is a technique that has given much satisfaction to patients and professionals, it allows to have a much more youthful and healthy look. Whitening is a cosmetic dental treatment that reduces the original color tones leaving teeth whiter and brighter.
The product used is based on hydrogen peroxide or carbamide peroxide, it is a gel with neutral PH and contains desensitizers to increase patient comfort.
Tooth Whitening can be performed on a series of aesthetically compromised teeth or to a single tooth that may have darkened after a root canal or dental trauma. Can be performed in any person who wishes to have their teeth whiter.
Teeth Bleaching is indicated for:
Stains caused by eating and drinking habits
Teeth Bleaching is contraindicated in:
Women who are pregnant or breastfeeding.
Children under 14 years of age.
Anyone allergic to resin.
Anyone allergic to peroxide.
Teeth Whitening can be:
* Internal Teeth Whitening (non-vital teeth only): Teeth that underwent a root canal are called non-vital teeth. If it's a tooth that underwent endodontic treatment the internal bleaching technique is used, that can be supplemented with external whitening techniques.
* External Tooth Whitening: The current techniques for external whitening are based on the use of two products: Carbamide Peroxide (usually for outpatient treatment) and Hydrogen Peroxide (mainly for clinical treatments).
The entire treatment lasts about an hour, it starts with a profuse cleaning of all teeth, then we take the pre-operative color tone, continue to apply a gingival barrier in both arches, dry the teeth and apply a gel on the enamel surface and if necessary apply full arch lamp that activates the product at the same time in all teeth to be whitening, with two or three short breaks to renew the whitening product we put on the teeth, leaving it between 30 and 40 minutes.
After the last application the gel is removed, rinse and fluoride topication gel to prevent sensitivity.
The intensity of whitening will depend on each patient, their particular color to be reviewed by the specialist to determine the expectations of whitening. Typically, a check up per week. In some rare cases the treatment should be continued for several weeks.
The final bleaching obtained will remain unchanged in the mouth for about 24 months, depending on each patient, teeth, and their care. In any case, when the bleaching decays, you will never recover the original color, the teeth will always look whiter. In this case it will be enough with a "reminder" of the whitening treatment to recover the maximum initial whitening.
External stains due to coffee, tea, tobacco, sodas, spinach, drinkable ron-based vitamin complex, chlorhexidine mouth rinses, may be removed by cleanings or daily use of toothpaste.
While it can be performed on an outpatient, it is best to do it in the dental office, as treatments made in the patient's home can give serious problems of sensitivity, even irreversible.
It is advisable to discontinue toothpaste or mouth rinses with fluoride 15 days before the bleaching to optimize treatment outcomes (fluorine "reinforces" the enamel through the transformation of hydroxyapatite into fluorapatite). Also you must discontinued 15 days before desensitizers products in liquid or toothpaste (Desensin, Sensodine, etc.) based on potassium nitrate and other components that could interfere with the bleaching.
After teeth whitening fluoride rinses and brushing with fluoride normal pasta (but not colored, for two weeks).
The first week after whitening is important to take care and follow the "white diet"(no spinach, no wine, no coffee, etc.). Avoid carbonated drinks and any food product that cause staining or acidic foods (pineapple, kiwi, citrus).
