The natural colour of the teeth varies considerably from one person to another. The natural tints of the teeth are grouped into four families as follow; (A) Auburn or reddish-brown, (B) Yellow-reddish, (C) Gray, (D) Gray-reddish. Indeed, it represents the colours of the teeth of the great majority of the population.
Several elements contribute to the yellowing of the teeth. Tobacco contains nicotine, which transmits its yellowish colour to the teeth, especially when a person smokes very often. Soft drinks, tea, coffee, red fruits and red wine also affect the whiteness of the teeth. However, the dentine covered by the enamel is of a dark colour and it is the outer layer of the enamel that gives it a lighter colour. With the regular consumption of acidic foods, this layer will be thinned and therefore, the teeth will be yellower. Some types of antibiotics can also be the cause of teeth yellowing.
The most popular techniques of professional dental bleaching, also known as teeth whitening, are laser tooth whitening and home dental whitening. The latter consists in using an individualized gutter. A dental whitening treatment should never be undertaken if the person is under 12 years old and the eruption of permanent teeth is not complete. Besides it is not recommended for pregnant or lactating women because the peroxide solution can cross the placental barrier and affect the foetus and it can also end up in the breast milk.

Different dental bleaching methods
The whitening agent acts on the surface of the enamel tooth and the dentin under the enamel. It never reaches the pulp, the internal part of the tooth, because it is not powerful enough to have an effect on it. The most commonly used products for tooth whitening are; Hydrogen peroxide, carbamide peroxide and urea peroxide.
The peroxide is able to attack the dark molecules that have accumulated on the tooth enamel and dentine to break them with the oxygen it contains.
Laser teeth whitening:
It is also known as chair whitening since it is done in the dentist's office. Indeed, the laser accelerates the reaction of the chemical components contained in the whitening product. Besides, the light projected on the teeth favours the penetration of the gel to the dentine. This revolutionary aesthetic treatment gives an effective result in one sitting. The dentist first photographs the teeth, then, performs a professional cleaning and later compares the initial tint with the colour obtained after bleaching. Indeed, they place a mouth opener and apply the gel directly to the teeth, dried by the lamp. This gel is pH-neutral, so there is no need to protect the gum. Then, the teeth are lighted by the plasma lamp for 20 minutes. The gel is removed and this same procedure is repeated twice. The final result will be determined by the colour scale.
Teeth whitening using an individualized gutter:
Teeth whitening using the gutter is the most used home method. The solution required is either hydrogen peroxide (a mixture of hydrogen peroxide) or carbamide peroxide (1/3 hydrogen peroxide and 2/3 peroxide of urea). The dentist takes dental impression and makes two customized plastic gutters for the patient's teeth, then gives them the whitening kit and the associated recommendations. The whitening gel penetrates the micro porosities of the enamel and removes stains and accumulated deposits. They must be worn according to the dentist’s prescriptions.
The patient will then have to place the whitening product by themselves in the gutters and wear it for a few hours each day or at night. The treatment lasts an average of two weeks. The results vary from person to another and are usually visible after few days. This type of treatment has significant advantages, indeed the concentrations used are important but lower than a treatment performed in the dentist's office. If, during treatment, the patient feels extreme sensitivity, they should stop the treatment to avoid damaging the nerve of their tooth.
After teeth whitening Procedure

The discomfort felt in the gums after treatment does not last and the irritation will disappear after 48 hours at the latest, because the mouth restores quickly. The effects are neither dangerous nor long-lasting. The first 2 days after the session of the teeth whitening treatment, the patient must not eat food prepared with colouring spices such curry and the patient should also avoid eating fruits such as red berries or rink their juice or wine etc.
