The structure of a Tooth.
As the magnification is increased you can see how the enamel surface is not smooth but consists of a labyrinth of fissures and crystals. You can really understand why keeping food particles out of these fissures is really important this.
Your teeth are designed to last much longer than you are. Enamel is the toughest material living organisms are able to produce and is incredibly resistant. Archaeological digs have found skeletons several thousand years old, with healthy teeth still intact. The exterior the tooth id covered and protected by in normal the hardest tissue in the human body. Although, it’s capable of resisting. The shocks chewing enamel can be penetrate by tiny particles such as bacteria if enough bacteria into the tooth. It starts to decay and former cavity.
The enamel surface appears increasingly marked 2 different types of issue as little a hole are cracks parallel to each other. These fissures reflect the composition, it make up a massive tiny elements called prisons all packed together and leaning obliquely. A higher magnification, it’s clear that. The scenario is repeated tiny rough shaped roads all point in the same direction and there are called “Crystals have appetite” the same crystals are found in bone and appetite crystals make up only 96 percent in normal. The remainder invisible consists of water and tiny proteins that cover and join together.
The enamel is formed by special sales during the growth that and teeth. It is only made once if it became worn the body cannot replace it! Closet still and the appellate crystals appears fine layers stacked up on each other.
Finally, the atomic structure of an appellate crystals, it’s a mineral made up of phosphate and calcium grouped together to form a well – ordered framework.
