The teeth whitening kit: good or bad idea ?

blanchir les dents

How to have white teeth and whiten teeth naturally? Whitening teeth is an essential step in oral health. Instead of going to the dentist, why not try home tooth whitening? Who doesn't dream of beautiful teeth and a bright white smile? Teeth whitening to remove stains and achieve a natural colour with a dazzling smile is now within everyone's reach, thanks to teeth whitening kits.

Here's a guide on whether or not to opt for a teeth whitening kit to whiten your teeth.

What is a tooth whitening kit?

Home tooth whitening kits are only for people who have yellowed or greyish tooth enamel. They usually consist of a tray and a small lamp. A whitening gel is placed inside the tray. It should be worn for at least 30 minutes a day. The effectiveness of the whitening kit starts to be felt after 5 days. It is a technique that allows you to gradually regain whiteness when the yellowing is not too severe. You can also have your trays made to measure so that the use of the kit is a little more practical, but it is a little more expensive. On the other hand, all of these teeth whitening kits are not as effective as the vast majority of whitening products that are used by dentists. The only main advantage they have is that they are much cheaper.

The different components of a tooth whitening kit

Here are the different components of a tooth whitening kit:

  • The whitening gel with a tray and a UV lamp : This is the kit that works best. It is similar to professional teeth whitening.
  • Whitening strips : These have a whitening gel that reduces the stains below the surface of the enamel. They are a little less effective than trays but are still a good solution for people on a budget.
  • The whitening pen : This is a brush that allows you to put a whitening product on the enamel of your teeth.
  • Charcoal powder : This is a black charcoal powder that whitens teeth. You will get less results than with a tray. However, the price is favourable. 

How the different components of the tooth whitening kit work

1)The whitening gel

This is an agent that consists mainly of chemicals that penetrates the enamel of the teeth and their outer layer. It triggers a chemical reaction. The main purpose of its action is to separate all the components that stain the tooth. The origin of this staining is often an oxidation reaction. Tooth whitening gel should be applied with a syringe to clean teeth.

2) Whitening strips


When you apply the strips to your teeth, the whitening gel is pressed against the surface and held in place, allowing it to penetrate the tooth and begin its whitening work. The strips should be applied directly to the teeth for up to 30 minutes a day to target stains on the teeth. They are applied daily over a period of two to three weeks.

3) The whitening pen


The teeth whitening pen has a brush-like tip that allows you to reach places like the spaces between the teeth to whiten evenly. The method of use is quite simple: simply paint the gel onto the teeth and leave it on for 10 to 30 minutes. Then paint the teeth of the smile on the outside. It is important to use it at least once or twice a day for 15 days.

4) Charcoal powder


Simply take a clean toothbrush and put some charcoal powder on it. To do this, you need to moisten your electric or manual toothbrush. You then need to dip it in the charcoal powder. You can then start brushing your teeth in very small circular movements for about two minutes. Finally, you should rinse your mouth well and clean your toothbrush.

You can try the Y-Brush toothbrush to brush your teeth with charcoal powder. It is a toothbrush that removes 15% more plaque than a traditional toothbrush. It helps to make your teeth even whiter than if you had used the charcoal powder with another toothbrush.

The effectiveness of tooth whitening kits

It is true that tooth whitening kits are effective after a few uses. However, home tooth whitening kits do not offer the same results as a dental bleaching at the dentist because it is a risky operation. This is because the oral products in the commercially available tooth whitening kit are subject to a limit of 0.1% hydrogen peroxide, whereas professionals can use products that contain around 6%. However, you can't extend the pause times as the result will not be any better and it may damage your teeth:

Here is a list of all the risks that tooth whitening can entail:

  • Damage to the enamel and dentin : this prevents the tooth from defending itself naturally.
  • Weakening of both the tooth and the gum : shocks will be felt much more strongly.
  • Increased sensitivity of the tooth : It will be much more sensitive to pain.

We hope that this guide has helped you understand that the teeth whitening guide is a good idea to whiten your teeth at a low cost and to achieve significant results quickly. However, we hope that you have also understood that the home tooth whitening kit is less effective and can in some cases have negative effects. It should therefore be used with caution and for a short period of time.
