What is it

What is teeth whitening?

Updated 12 May 2026

Teeth whitening is a treatment aimed at lightening the colour of teeth by removing stains and discolouration. It is the most popular aesthetic dental treatment. Whitening is most effective on extrinsic or surface stains. To maintain a brighter colour, the treatment must be repeated periodically, as it is not a one-off procedure.

Some habits can cause the whitening to start fading. Smoking, as well as consuming foods and drinks containing colorants, can accelerate this process. If these harmful habits are avoided and the maintenance recommended by specialists is followed, another whitening treatment may not be needed for the next 6 to 12 months.

Step by step

Teeth whitening treatment phases

1

Gum protection and gel application

The dental professional will apply a substance that covers and protects the gums around the teeth. They will then place a whitening gel on them, which will subsequently need to be activated with a light to be effective.
 

2

Activation with LED or laser light

If the whitening agent needs to be activated, an LED or laser lamp will be placed for the specified treatment time. The treatment may require several sessions, but they can be carried out in a single appointment.

3

Taking impressions and fabricating mouth guards

In the case of home whitening, the professional will take impressions of the upper and lower arch and will fabricate custom mouth guards that will fit the teeth perfectly, ensuring the whitening agent remains in contact with them.

4

Use of the mouth guards at home

Once the mouth guards are available, the whitening gel will be placed inside them and they will need to be worn for several hours every day.

FAQs about teeth whitening

Teeth whitening is an aesthetic treatment that aims to lighten the colour of teeth. This is achieved through the use of whitening agents containing hydrogen peroxide or carbamide peroxide, which break down stains into smaller particles, making the colour less concentrated and the teeth whiter.

Many people who wish to improve the appearance of their teeth may be candidates for teeth whitening. However, not all types of discolouration can be treated with whitening, so an assessment by a dentist is essential to determine whether the treatment is appropriate.

The safest and most recommended whitening treatments are those carried out at a dental clinic by an expert with the safest and most effective technology, such as photoactivation (LED light activation at the clinic).

The teeth whitening effect can last from several months to several years, depending on factors such as diet and oral hygiene habits. Avoiding foods and beverages that stain, as well as regular use of dental care products, can help to prolong the results.

Teeth whitening is generally safe when carried out according to a dental professional's instructions. Some people may experience temporary dental sensitivity or gum irritation, but these effects are usually mild and temporary.
