Everyone wants to have white and straight teeth, but the reality is that most people are born with teeth that are not so white and slightly yellow. Some people even believe in prescriptions, such as using acidic liquids like vinegar and lemon juice to remove the yellow color of teeth and make them whiter, not knowing that these very acidic things will only corrode the tooth enamel, which will in turn cause damage to the teeth.

In fact, the color of normal teeth is slightly yellow, from the outside to the inside, teeth can be divided into enamel, dentin and pulp. The dentin is yellow and the enamel is slightly transparent, so under normal circumstances, teeth look yellowish. The main causes of abnormal yellowing of teeth in many people are endogenous and exogenous.

Endogenous yellow teeth are mainly due to dental fluorosis and tetracycline teeth.

Dental fluorosis: There are some areas in the country where the drinking water has high fluoride content, coupled with the use of fluoride toothpaste on the market, which leads to dental fluorosis, which manifests itself as yellowing of teeth.

Tetracycline teeth: Many people born in the 1960s and 1970s have left a lifelong regret – tetracycline teeth. Tetracycline, also known as Akromycin, is a broad-spectrum antibiotic, and this antibiotic has an effect on the dental development and bone development of fetuses, infants, and young children, which can lead to yellow-stained teeth.

However, nowadays, due to the scientific use of medication and better living conditions, the occurrence of endogenous yellow teeth is becoming less and less frequent. Yellow teeth are now generally due to exogenous causes. Exogenous is generally related to dietary habits and hygiene habits.

Dietary problems: frequent consumption of food containing pigment, such as strong tea, juice, chocolate, smoking, etc., resulting in pigment residue on the tooth surface, which will cause tooth discoloration over time.

Hygiene habits: Many people do not develop the habit of brushing their teeth on time and rinsing their mouth after meals, which leads to tartar and stains deposition, which will attach to the tooth surface over time.
