Why do tooth decay occur, these are the main causes

There are many people who are plagued by tooth decay in life, so do you know why tooth decay occurs? In fact, there are many causes of tooth decay in life, so let's learn more about it.

Tooth decay is very common in life, and many people wonder why it causes tooth decay for no reason. Let's talk in detail about what are the main culprits of tooth decay.

Why do you get tooth decay

1. Bacteria

It is a necessary condition for the occurrence of caries, and it is generally believed that there are two types of cariogenic bacteria, one is acid-producing bacteria, which are mainly Streptococcus mutans, Actinomycetes and Lactobacillus, which can decompose carbohydrates and produce acid, resulting in tooth inorganic demineralization; The other is gram-positive cocci, which can destroy organic matter and cause cavities in the teeth after long-term action.

2. Food

Mainly carbohydrates, which are not only related to the formation of plaque matrix, but also the main energy source of bacteria in plaque, bacteria can use carbohydrates (especially sucrose) metabolism to produce acids, and synthesize extracellular polysaccharides and intracellular polysaccharides, the organic acids produced are conducive to the growth of acid-producing and acid-resistant bacteria, and are also conducive to the demineralization of tooth hard tissue, polysaccharides can promote the adhesion and accumulation of bacteria on the tooth surface, and provide energy sources when exogenous sugar is deficient.

3. Host

Teeth are the target organs in the process of caries, and the morphology, mineralization degree and tissue structure of teeth are directly related to the occurrence of caries.

How to prevent tooth decay

1. Have regular dental check-ups

Caries is a chronic disease in which teeth decay in about a year and a half due to the combination of the above-mentioned caries-causing factors. Regular dental check-ups at the dentist can keep track of the onset of oral cavity and teeth, treat them in time, and stop the further development of caries.

2. Choose fluoride toothpaste

Fluoride toothpaste with a high-quality toothbrush can enhance the plaque removal effect, protect the teeth from bacterial acid production, transform the hydroxyapatite structure of tooth enamel into a more acid-resistant fluoroapatite, and repair tooth enamel that has been damaged by acid.

3. Pay attention to your eating habits

Eat more rough, hard and fibrous foods, which have a friction and cleaning effect on the tooth surface and reduce the accumulation of food debris. Eat more natural foods, healthy foods, such as vegetables, fruits, meat, eggs, fish and shrimp, etc., try to avoid sweet and sticky foods, such as: all kinds of sugar, chocolate, biscuits, preserves, etc., sugary drinks are the most harmful to the health of children's teeth. These sweets and beverages mostly contain sucrose, maltose, etc., which have a strong cariogenic effect.
