Bleaching safe

Bright white teeth inspire sympathy and increase your self-confidence. So it's not surprising that teeth whitening is popular. Yet there are still many questions about this subject. Is it safe, which methods are there and is the effect lasting?


Teeth consist of dental bone and enamel. The color and thickness of the dental bone determine the color of the teeth. It differs from person to person.



Over the years your teeth can change color. This is caused by, among other things:

  • Cigarettes
  • Tea
  • Coffee
  • Wine


In addition, there are other reasons why teeth and molars are or become darker:

  • Aging process
  • Dead tooth as a result of tooth decay or an accident
  • Use of medication
  • Developmental Disorders


Bleaching methods

To make the teeth shine again, you can choose to have teeth bleached. There are two different methods: bleaching from the outside and bleaching from the inside.


After a root canal treatment, it is possible to bleach a dead tooth from the inside. This is done by inserting a paste containing bleach into the tooth, after which it is sealed with a temporary filling. After a few days the tooth becomes lighter in color. It may be necessary to repeat this treatment a few times. When the desired result is achieved, the tooth is provided with a definitive filling.


Bleaching of teeth and molars from the outside happens especially if you suffer from slight discolorations and can be done in different ways. You can be treated by a dentist or you can bleach your teeth and molars yourself.


The dentist

The dentist starts treatment by protecting the gums from the high concentration of peroxide that is used. He does this by means of a gum protector (a rubber cloth or a special gel). The whitening gel is then applied to the teeth and molars. This gel has to act for some time.


To speed up the process, the dentist uses a bleaching lamp or in some cases a laser. It may happen that a small amount of peroxide ends up on the gums. This causes white burn marks, which disappear within a few hours.


Bleaching at home

You can also choose to whiten your teeth at home under the supervision of the dentist. The dentist then makes an impression of your teeth, after which a dental technician makes a so-called bleaching spoon.


Then you get the bleaching spoon, the bleaching gel (carbamyde peroxide) and instructions home. To achieve a good result, you have to hold the bleaching spoon three to six hours a day. That is possible at any time. Even when you sleep. Results can be seen after one to four weeks. If the teeth are severely discolored, the treatment must be repeated.


Bleaching process

During treatment with a bleaching spoon it is advisable not to do the following things, as they can influence the bleaching process:

  • Drink coffee, tea, carbonated soft drinks, citrus juice or wine.
  • Eating food with coloring agents, such as fruit jam.
  • To smoke.


Please note: always get advice from a dentist before you whiten your teeth and molars at home. This is because there are products on the market with too high concentrations of peroxide, which can damage your teeth.



The result of a bleaching treatment is different for everyone, because the whiteness of the teeth depends on the original color of the teeth and molars.


If you ensure good oral hygiene and eat healthy food, your teeth will stay white for several years after treatment. It can happen that the teeth still discolor as a result of growth of the dentine, smoking a lot and / or drinking a lot of coffee, tea or wine. You can then choose to have your teeth whitened again.



If you are considering whitening your teeth, talk to a dentist first. He can determine whether your teeth are healthy and indicate what results can be achieved. Fillings, veneers, crowns and bridges were not included!
