Teeth are essential for chewing and swallowing food. Canines, incisors, premolars, molars: each tooth has a specific function. Although the problem of “yellow” teeth is mainly aesthetic, it can be a nuisance for the person who is affected and complex it. However, a complex can hinder self-confidence, the relationship with others, the potential of seduction of an individual and his sociability. So, yellow teeth: who are the culprits?

The crown of the tooth is made up of three layers of which enamel and dentin are part. The enamel is the visible part of the tooth. It is transparent and fully mineralized. It is the hardest part of the human body. It protects teeth from acid attacks and the effects of chewing. Dentin is the underlying layer of enamel. It is more or less brown. This part is vascularized (= blood vessels that supply the body).

The shade of the tooth is determined by the coloration of the dentin and the thickness of the enamel.

Ia manatua:

The enamel wears out over time and the accumulation of debris of all kinds. This wear makes it less and less thick and more and more transparent. The more transparent it is, the more visible its underlay, the dentin, is.

Whether it is internal or external factors, PasseportSanté has conducted its investigation to reveal to you who is responsible for the yellowing of teeth.

When it comes to white teeth, we are not all born equal. The color of our teeth is related to the contrast with the color of our skin or our gums. The color of our teeth can be determined by genetic factors, more specifically heredity.

This is not news: tobacco is harmful to health in general, and also to the oral cavity. Some components of cigarettes (tar and nicotine) cause yellowish or even blackish spots, which can be perceived as unsightly. The nicotine attacks the enamel, while the tar is responsible for browning the coloration of the dentin. Ultimately, a simple brushing will not be enough to remove these spots. In addition, tobacco contributes to the development of tartar which can be responsible for the formation of cavities.

Dentin is the vascularized part of the tooth. Through the blood, taking medications, including certain antibiotics, affects its color. Tetracycline, an antibiotic widely prescribed during the 70s and 80s to pregnant women, has had an impact on the color of baby teeth in children. This antibiotic prescribed to children has had a decisive impact on the color of their permanent teeth. The color can vary from yellow to brown or even gray.

Fluoride strengthens tooth enamel. It helps to have stronger teeth and more resistant to cavities. Overuse of fluoride causes fluorosis. This is the formation of stains on the teeth which can dull and discolour. In Canada, the government has implemented regulations concerning the quality of drinking water. To improve the quality of oral health, the fluoride concentration is adjusted in the drinking water. The Office of the Chief Dentist was established in 2004.

Certain foods or drinks have the annoying tendency to yellow the teeth, hence the importance of brushing. These foods act on the enamel. These are: – coffee – red wine – tea – sodas such as coca-cola – red fruits – sweets

Having good oral hygiene is essential. It prevents acid and bacterial attacks in the mouth. It is therefore necessary to brush your teeth at least twice a day for 2 minutes. Floss works where the toothbrush cannot. Brushing your teeth removes tartar and helps maintain the whiteness of your teeth.

To fight against the yellowing of their teeth, some people resort to tooth whitening with the use of hydrogen peroxide (= hydrogen peroxide). This practice is not to be taken lightly. Improper use of hydrogen peroxide weakens and sensitizes teeth. An oral check-up is therefore more than necessary. Whether it results from an aesthetic or medical act, tooth whitening must follow very strict regulations.
