Information for home whitening treatment

Successful home whitening treatment and avoid complications



Informations générales


Un traitement de blanchiment des dents a pour objectif d’éclaircir la teinte des dents. Lorsque fait adéquatement, un blanchiment n’endommage pas les dents ou les gencives. Dans la plupart des cas, un éclaircissement substantiel peut-être obtenu. Il est toutefois impossible de garantir le résultat final car un blanchiment est produit par une réaction chimique à l’intérieur de la dent et non par une «teinture» qu’on applique en surface. Comme pour tout traitement, le blanchiment des dents comporte certains risques et limitations. Bien qu’ils représentent rarement des risques suffisamment importants pour en contre indiquer le traitement, ils doivent quand même être pris en considération afin de prendre une décision éclairée.


General information


A tooth whitening treatment aims to lighten the tooth color. When done properly, bleaching does not damage the teeth or gums. However, results may vary because bleaching is produced by a chemical reaction inside the tooth and not by a "dye" applied on the surface. As with any treatment, tooth whitening involves certain risks and limitations.

Am I a good candidate for a bleaching treatment?


Overall, everyone may be a good candidate for teeth whitening but the following points should be considered:

• Teeth with a yellowish or brownish tint respond better and more rapidly to bleaching than those with a greyish tint, as in the case of tetracycline staining where more intensive treatment is required.

• White and chalky patches on the surface of the enamel will not disappear, but will become less apparent as the rest of the enamel clears.

• The restorations and / or prostheses present will not change color. All material other than the natural enamel of the teeth will not respond to treatment (composite resin restoration, porcelain facets, porcelain crown, acrylic prostheses etc.). Sometime after bleaching it is possible to replace them to ensure a better aesthetic fit.

• Bleaching is not effective against stains or tartar. Successful scaling and polishing are highly recommended before starting the bleaching process.

• Where gingival recessions are present and the roots are exposed, they can remain darker than the enamel-covered parts after the whitening. It is possible that the roots become temporarily sensitive to cold and heat.

• As a preventive measure, we do not recommend bleaching treatments for pregnant or nursing women. The same applies to patients with severe health problems and in whom the immune system is affected.

Most frequently reported problems

Sensitivity of teeth:


Some patients report sensitivity to cold or heat during treatment. This sensitivity is transient and gradually fades after completion of treatment. If your teeth are not particularly sensitive to cold or heat, the sensitivity caused by bleaching should be only minor. If, on the other hand, your experience increased sensitivity when your teeth are exposed to temperature changes, bleaching may increase sensitivity. In these cases, it is recommended to alternate treatment with a few days of interruption. In addition, application of a desensitizing agent may be useful before, during and even after bleaching.

Gingival irritation:


If the gums become irritated, it is likely that it is caused by excessive bleaching gel in the gutters or by excessive wear of the gutters. It will then be necessary either to reduce the amount of gel deposited in the gutter, or to reduce the exposure time or even to interrupt the treatment temporarily



Once treatment has been completed

Final color obtained:


Whitening can vary, this depends on the color of the tasks present at the outset, the anatomy of the teeth, the general condition of the teeth, the patient's cooperation and the duration of the treatment.


Recidive :


Teeth whitening is not permanent. With time and pigments contained in food and drink, the teeth will gradually resume their original hue. One can maintain an optimal state by doing periodical "retouching" a few times a year. It is then important to properly maintain the bleach gutters and to use an unused bleach. Gel syringes can be sold individually.
