BLEACHING

BLEACHING

Tooth whitening is an aesthetic, non-invasive dental treatment that aims to whiten teeth in order to improve the appearance of the smile. To do this, whitening products are used, which act on the surface of the teeth to change their colour without wearing down or weakening the teeth. It is a simple and safe procedure in which the dentist makes a diagnosis and selects the most appropriate technique for each case.

INTERNAL BLEACHING

Internal whitening is a treatment like tooth whitening, but which aims to change the shade of just one tooth. The whitening product is applied inside the tooth structure and not on the enamel surface, as is the case with other techniques.

Changes in tooth colour are quite common, and they don’t just happen on the outside of the tooth. Internal tooth darkening occurs for various reasons, such as:

Trauma;
Necrosis of the pulp;
Iodine contamination;
Medication inside the canal;
Spillage of blood on the internal structure of the teeth.

It is in cases like these that we most often see a change in colour. The tooth turns greyish, but with internal whitening, this darkening is minimised.

BLEACHING IN THE OFFICE

A gel with a high concentration of whitening agents is applied and left to act using a laser.
During the procedure, the dentist removes the lips and protects the gums with a light-curing resin, which hardens when it comes into contact with light.
This is necessary in order to create protection from the gel used.

The main advantage offered here is instantaneity due to the high concentration of the whitening agent.
Thus, results are seen more quickly, as teeth are whiter from the very first session.

BLEACHING AT HOME

The main difference between in-office and at-home whitening is precisely the time it takes for the treatment to be finalised and generate results.
This is because the gel used in the office has a higher concentration of whitening agents, speeding up the process.

However, to be done at home, whitening plates are used, also known as trays, which the dentist will make and deliver to the patient.

In addition to the tray, the professional provides the patient with the gel in the ideal concentration for the case and monitors its progress.

The patient should then apply the gel to the tray and place it on their teeth.

You should always follow your dentist’s recommendations on how long and how to use the whitening gel and tray.
