Here, a distinction is made between "In-Office" Bleaching and the so-called "Home" Bleaching distinguished. Before bleaching, it is always recommended to perform a Oral hygiene This removes any existing plaque that would otherwise interfere with the bleaching result.
In Office Bleaching
The bleaching gel is applied to the teeth at the treatment chair. To protect the gums, they must be specially covered beforehand. After that, a bleaching gel (special hydrogen compound) is applied to the teeth in several sessions of 15 minutes each. The whitening effect occurs immediately after a single application and is repeated 2 to 4 times in the same session (as desired). Basically, you should perform oral hygiene before bleaching so that plaque, tartar, etc. are removed beforehand, as these interfere with the bleaching process.
Here, impressions are taken and individual splints are made into which the bleaching gel is applied. These splints should then be worn for a few hours a day (about 1 week - preferably at night) to achieve the desired result. This variant has the advantage that the application can be repeated if necessary (after medical consultation). We recommend this variant if In Office Bleaching has already been successfully applied. Afterwards, you can easily maintain the color of your teeth with the whitening trays.
However, sufficient fluoridation should be observed with both methods to prevent possible sensitization of the teeth.
Another method to remove root-treated teeth, which sometimes more sometimes less affect the aesthetics, especially in the front due to their grayish color, is the "Endo Bleaching". The bleaching gel is applied into the tooth through a small access point towards the tongue, thus lightening the tooth from the inside. The bleaching gel remains in the tooth for up to 7 days and is then replaced or removed depending on the desired effect. After bleaching, the access opening is closed again with plastic.
