Teeth whitening has been a huge success lately. There are many methods of teeth whitening available today. Whitening can be done at home or in a dental office. There are also smile bars, which offer teeth whitening services. You can also purchase a teeth whitening kit from pharmacies and drugstores. There are even supermarkets that sell them and you can also order them on the internet. Many products and techniques are used to whiten teeth. Dental bleaching facilitates the lightening of the teeth.  

Here is a guide that will help you understand why you need to have dental whitening done at the dentist and what are the different elements to take into account when you have dental whitening.  

Why whiten your teeth?

Everyone wants to have a beautiful smile. White teeth make it possible to have a bright smile. Our teeth are not naturally white, they are pearly white. Brushing your teeth is not enough to remove stains. Consumption of certain foods such as coffee, tea, wine or smoking changes the color of the teeth, often turning them yellow. Age can also make teeth darker. Tetracycline abuse can also affect the formation of teeth. Tooth whitening is a process that restores the brightness of our smile. After whitening, you will have a radiant smile. Whitening techniques such as scaling help to maintain good oral health. Dental hygiene is guaranteed with the use of dental bleaching at the dentist.

However, you can always use an effective electric toothbrush to start making your teeth whiter. For example, you can try the Y-Brush toothbrush. It is a toothbrush that brushes all the teeth and their surface at the same time, which allows you to brush from everywhere and therefore have much whiter teeth.

What is tooth whitening and what are the contraindications?

Tooth whitening is a process that consists of lightening the enamel and dentin. The yellowish or grayish stains of the teeth are whitened with specific products such as hydrogen peroxide. An oral examination is necessary before performing a tooth whitening. Whether at the dentist's or at home, one needs the advice of a dental surgeon before whitening one's teeth with a whitening agent or with a good dental bleaching at the dentist.

Only a complete dental check-up can determine whether or not there is a contraindication. The presence of untreated tooth decay prevents whitening. If you have gum irritation or devitalized teeth, you cannot perform tooth whitening either. Weak enamel is also a contraindication for tooth whitening. Children under the age of 16 should not have teeth whitening. As a precaution, pregnant and breastfeeding women are not allowed to have teeth whitening. It is also contraindicated for people with sensitive gums and those who are allergic to hydrogen peroxide. In case of gum disease such as gingivitis or periodontitis, it is forbidden to whiten your teeth. If you have fillings, veneers or crowns, your teeth cannot be whitened either.

The different types of tooth whitening that are not effective and dangerous

LED light treatment

This is a whitening treatment with a small portable LED light. The LED light is usually sold with 2 tubes of whitening gel and dental silicone. It is recommended to do this treatment for 15 to 20 minutes per day. There is no mention of how long it is recommended to do this treatment in order to get the results you want. Most LED light treatments contain carbamide peroxide. There is therefore a risk of burning the gums and oral mucous membranes when using them. Barriers are therefore important to prevent the peroxide from coming into contact with the gums or the inside of the mouth.

Self-adhesive strips


This tooth whitening treatment is based on hydrogen peroxide. These are strips that are pre-cut and put inside the whitening product. You must apply these strips to your clean teeth and leave them in place for 30 minutes. This type of over-the-counter teeth whitening treatment does not offer the same results and safety as all other products prescribed by dentists. In fact, the concentration of peroxide is lower than that contained in whitening products sold in dental offices. In addition, the position of some people's teeth makes it difficult to apply the strips and leaves demarcations when they do not completely cover the tooth.

What are the advantages of whitening with a dentist ?

The expertise of a dentist is the best option for whitening teeth. The whitening process is more secure and the whitening products used follow the standards. The safety and effectiveness of the treatment are also ensured when whitening is done in a dental office. There are 2 types of whitening performed by a dental surgeon. Chairside bleaching and outpatient bleaching. Chairside bleaching is performed in a dental office in one or two sessions. A hydrogen peroxide bleaching gel is applied to the surface of the teeth. The bleaching process is accelerated by the use of blue light. This process is not harmful to our teeth.

Ambulatory whitening, on the other hand, is continued at home after the sessions at the dentist's. The professional takes impressions of the patient's teeth to make the appropriate trays. The treatment is then continued at home with hydrogen peroxide. The trays are worn for about 4 hours. The trays are used for 3 weeks to have an effective lightening. With teeth whitening at the dentist, your teeth will shine again and a bright smile will dazzle the audience.

You have many choices for the teeth whitening you want. Please compare the price and choose the one that is right for you. We still recommend that you get your teeth whitened by an expert hand and have a dental bleaching done at the dentist.

We hope that this guide has helped you understand that dental bleaching at the dentist offers results that you will not find anywhere else. If you take into account all the contraindications, you will not have any risk of oral problems. On the other hand, other teeth whitening techniques are not really recommended because they are dangerous for your oral health
