The toothpaste is the most Lasted of the body and constitutes the outermost layer of the tooth. It is located in the entire dental crown, that is, the visible part of the tooth and is in contact with the oral environment.
Mature enamel is composed of a high percentage of inorganic matrix, hydroxyapatite crystals (the hardest mineral in the human body), with calcium and phosphate minerals that offer greater resistance. Enamel is ectodermal, acellular, avascular in origin and without innervation. The maximum thickness of the enamel is between 2-3mm. Enamel is related to the buccal environment on its external surface, to the dentin (intermediate layer of the tooth) and to the cementum in its cervical part of the crown, that is, in the dental neck where the root begins.
Between the physical properties of the enamel we find its high hardness thanks to its high mineral content and organization of the crystals. The Colour It ranges from yellowish-white to gray, has translucency, low permeability, and high radiopacity. Thus, the color of the layer underlying the enamel, that is, the dentin, is what determines the color of the tooth and is seen through the enamel.
Enamel is chemically composed of 1% organic matrix, 3% water and 96% inorganic matrix. Histologically, enamel is made up of a basic structural unit known as the enamel prism that forms the mineralized extracellular matrix. In contrast, the area of the periphery of the dental crown and the enamel-dentin junction area are made up of aprismatic enamel.
Over time, the enamel undergoes a physiological wear normal, produced by the forces of chewing. This process of demineralization of the tooth can be aggravated by different factors such as, for example, the consumption of citrus fruits or other acidic foods or beverages, with high sugar content such as soft drinks etc.
Demineralization of the tooth increases its susceptibility to originate cavities or other dental pathologies. This process leaves the teeth in the absence of their main layer of protection and defenseless against attack by bacteria. The metabolism of oral bacteria gives rise to acidic products that attack the teeth, so that without the resistant layer of enamel, they are more prone to develop tooth decay.
The specialists of our dental clinic Smile Care Plymouth Dental Plymouth advise in these cases to insist and become aware of the importance of having good habits of daily oral hygiene to keep teeth clean and protect them from bacteria attack.
They also advise the use of toothpastes fluoridated, since fluorine is a component that has properties antimicrobial Y remineralizing of the tooth, so that they protect it and reinforce its enamel layer. As well, they recommend performing professional oral cleanings at the dental clinic annually, to be able to deeply extract the bacterial plaque and the calculus that is deposited on the teeth and on the gums over time. All this is very important to be able to preserve our teeth in the best condition in the long term and to take care of our oral and general health.
