Tooth enamel is the thin outer shell of a tooth. It covers the crown of the tooth, which is the part that can be seen outside the gums. Although it is the outer layer, the enamel is transparent. Dentin, the hard tissue underneath the enamel, is what gives color to teeth.
Tooth enamel is the white, hard, shiny outer layer of the teeth that covers the underlying tissues, i, ii It is the hardest substance in the human body, even stronger than bone, and is composed almost entirely of minerals. These minerals give strength to enamel, so they can protect teeth from damage and help them look shiny, white and healthy, ii. Enamel protects the inner and most fragile areas of the teeth, known as dentin and pulp. It is the first and most important line of defense against tooth decay.
If your enamel is damaged, you could develop tooth decay, temperature sensitivity, and even a dental infection.
Tooth enamel
is the substance that forms a layer around the top of each tooth. It is an extremely hard substance that is specifically designed to protect teeth from damage. Enamel is a shield that protects the vulnerable area on the side of the teeth, which can be damaged due to tooth decay.When you ask yourself: “What is tooth enamel? The answer is relatively simple. The term “tooth enamel” refers to the hard surface layer of the teeth. It is the main defense of teeth against tooth decay and is the hardest mineral substance in the body. While enamel is more durable than bone, the acids introduced into foods and beverages can endanger your enamel.
Soda and candy, in particular, produce plaque bacteria, which can weaken and destroy tooth enamel, softening the tooth surface. In addition, once the plaque has consumed the enamel, it can disappear forever. This micrographic image shows amelogenin, the protein in human tooth enamel, as it self-assembles in the laboratory, forming a network of tapes about 30 nanometers in diameter and 20 to 30 nanometers long. It is beyond the scope of this review to discuss the morphogenesis and histology of tooth formation in mammals, or the cellular origins and molecular signals used locally to direct odontogenesis; however, the reader is referred to some prominent publications that cover all of these topics (74, 262, 271, 377, 378, 403, 59.This partly explains the high benefit of fluoride supplements in toothpastes and drinking water for preventing tooth decay and reducing tooth erosion (393, 451, 67).

Enamel is much more mineralized than other dental structures and serves to protect dentin and pulp. Once the enamel is damaged, it allows cavities or other problems to cause additional damage to the underlying tooth. Enamel is degraded by plaque, bacteria, excess sugars and acids, which can become a cavity in the tooth over time.
Around the world, most dentists recommend that all people, throughout their lives, continuously expose their teeth to fluoride from sources such as drinking water containing fluoride (at 0.7 ppm) and toothpastes. The main part of the tooth, known as dentin, is actually the part responsible for the color of a person's teeth. This individual variation is associated with external factors such as diet and the chemistry of the water consumed during tooth formation. Basically, this is the first step in protecting the teeth themselves from conditions such as tooth decay, gum disease, periodontal disease, and other conditions that can lead to serious infections, chronic pain, or even tooth loss.
These first epidemiological studies led to community studies of water fluoridation that confirmed the reduction of dental caries when the water had between 0.7 and 1 ppm of fluoride ions, compared to the absence of fluoride. Now that you know what tooth enamel is, you'll also wonder if you can recover your enamel once you've lost it. This is illustrative of the fact that developing dental epithelium plays a role in tooth eruption, as well as in enamel formation. Rats and mice have become widely used animal models for studying tooth formation because rodents have continuously growing maxillary and mandibular incisors.
