These techniques are reserved for particular cases, and do not have especially to serve as a pretext for bad a oral Hygiène!

Techniques

External bleaching

Produced sold in pharmacy or large surfaces.

They are products with weak concentrations. They are thus less effective, but present less risks.

ambulatory Gutters

The dentist takes a print of the mouth, makes gutters, which will be applied every night lasting approximately two weeks.

Meetings with the dentist's surgery carried out by a Dental surgeon

It is the fastest technique, the products are concentrated, and often activated by the light. The meeting lasts half an hour at one hour; to envisage two meetings separated by two weeks for a good performance.

Internal bleaching

Internal bleaching consists in clearing up a devitalized tooth of the interior.
Often, the devitalized teeth take a darker coloring, being able to be unaesthetic if it is about a higher Incisive central. In this case one can, after being oneself assured that the canal obturation was quite tight, to deposit an adequate product inside the tooth, and to let it act during one week. One can possibly renew the product several times, until arriving at the desired color. This treatment could be renewed later if necessary.

Products

the products of bleaching act by demineralizing the surface layer of enamel. The risks of dentinal Hypersensibilité are strongly increased during and after the meetings.
In the same way a smoker wishing to clear up teeth yellowed by the tobacco will have preferably to stop smoking as a preliminary; if not colorings would be likely to return in a way even more important. Moreover, certain products of bleaching, in particular containing hydrogen peroxide, can slightly increase the cancer risks if they are used at a smoky person.

It is also necessary to avoid drinking coffee or any other food which can involve colorings right after a meeting.

general Counter-indications: to avoid in the expectant mothers and the minors.
