Why teeth are almost as hard as diamonds, they will cause tooth decay

Tooth decay is the most common dental disease, which is a disease in which the inorganic parts of the teeth are decalcified and the organic parts are destroyed.

Teeth suffering from tooth decay will never heal incurably, and will not be able to return to their original healthy appearance like other diseased tissues. After the first tooth decay, it can only prevent it from deteriorating further, and it is absolutely impossible to return to the original state, and it is impossible to immunize diseases such as smallpox and diphtheria by vaccination. This chronic disease occurs regardless of gender, age, wealth and ethnicity.

However, some people pay great attention to oral hygiene but have tooth decay in their mouths, and some people never care about their teeth and have their teeth intact throughout their lives, because the occurrence of tooth decay is not caused by a single factor.

There are many causes of tooth decay, but the more widely known is the theory of chemical parasitism or acid-making

Epithelial cells, bacteria, and food debris often remain on the surface of the tooth (called white scale when it is visible to the naked eye), and acid-producing bacteria (e.g., lactic acid bacteria, streptococcus, yeasts, staphylococcus...) are present in the toothWhen sugars (carbohydrates) enter, acidogenic bacteria will release enzymes to break down sugary foods and produce acids that will dissolve and soften the tooth surface, resulting in decalcification of the inorganic parts of the teeth and destruction of organic matter. There are three major elements of the formation of the whole cavity as described above:

1.Acid-producing bacteria 2Enzyme 3Substances that receive enzymes (e.g., sugars). Therefore, by removing any one of these elements, we can prevent tooth decay from occurring.

In addition to the acid-producing theory, there are some other factors that can cause tooth decay, such as:

1.The health of the teeth themselves will directly affect the rate of tooth decay. The mother's nutritional deficiencies during pregnancy will directly affect the fetus's teeth, and during pregnancy, drugs and infectious diseases will also cause the fetus's teeth to be unhealthy.

Diseases and nutritional deficiencies in children can also affect their dental health.

2.The pH content of saliva (saliva), the viscosity of saliva, and the antibacterial properties also affect the rate of tooth decay.

3.The morphological characteristics of the tooth itself: deep and narrow occlusal grooves or small dots on the buccal or lingual surfaces, in which food and bacterial debris can easily accumulate, so these areas are prone to tooth decay.

4.Tooth position: If the tooth position is not correct (irregular dentition), it is easy for food, bacteria, and debris to remain, and the chance of tooth decay will increase. If the teeth are aligned properly and properly, the chance of tooth decay will be lower.

In short, if we can prevent the occurrence of all these factors, the rate of tooth decay will inevitably be reduced.

Because the main element on the top of the tooth is calcium.

Whereas, calcium can react with acids.

So I can still get tooth decay.

Diamond has a hardness of 10 on the Mohs scale and a microhardness of 98 MPa (100 060 kg mm2), which is more than 1 000 times the absolute hardness of quartz and 150 times that of corundum.

Actually, it's not the teeth that are hard, it's the enamel on the surface of the teeth. Enamel is a highly calcified tissue that contains more than 96% of inorganic salts such as calcium, magnesium, and phosphorus. The hardness of enamel is 8, which is 2 levels softer than diamond, and as hard as topaz in stone!

So diamonds are harder than teeth!

The diamond is hard, the teeth are mainly calcium structure, and the diamond is C60
