The construction of tooth enamel is an amazing feat of engineering. The tissue is tough enough to resist dents and withstand decades of jaw-slamming activity. But it’s not perfect – scientists have yet to come up with a viable substitute. But they have developed artificial materials that are stronger than the real thing.
To find out more about how tooth enamel is formed, scientists have to study the structure of the tooth’s enamel. This requires scanning transmission electron microscopy (STEM) techniques. These techniques help scientists visualize the structure of the tooth’s enamel by revealing its intricate microstructures. This knowledge may be important for researchers to understand tooth decay and improve prevention.
Teeth have two types of enamel. The enamel of primary teeth is more opaque, while the enamel of permanent teeth is more translucent. As a result, the primary teeth appear whiter than the permanent ones. Hence, it is important to protect the enamel as much as possible. Various substances can cause staining of the enamel, making it appear darker or yellow. Ideally, enamel is colorless, reflecting the underlying tooth structure.
Enamel is produced by polarized columnar cells called ameloblasts. These cells secrete proteins that contribute to the formation of the enamel matrix. These cells contain proteins called tuftelins, ameloblastins, and enamelins. These proteins help in mineralisation of the enamel matrix. Ultimately, there is very little organic material in the tooth enamel.
The dentin, which holds the enamel in place, can also be damaged. When the dentin is damaged, the enamel cannot compensate for its loss. The dentin is weaker than the enamel, which causes the tooth to break easily. Therefore, it’s imperative to protect the dentin. For example, if you suffer from a toothache, it’s vital to treat the underlying condition. This will prevent further damage and prevent future dental problems.
Early signs of tooth enamel erosion are pain and increased sensitivity. You may also notice indentations, cracks, and chips. In addition, the enamel may become discolored. These conditions may cause the tooth to look yellow and uncomfortable. You may also experience pain and sensitivity to certain foods and temperatures. This condition can lead to tooth pain, tooth sensitivity, and tooth abscesses.
In addition to brushing, eating a healthy diet can also strengthen the enamel on your teeth. Avoiding foods high in acid can prevent tooth erosion. Drinking water also strengthens the enamel. Consuming sodas, citrus fruit juice, and fruit juices is also bad for the health of your teeth. These acids cause teeth to break down.
Enamel is made up of a complex biomaterial called hydroxyapatite. It is made up of layers of hydroxyapatite crystals that gradually change orientation with respect to one another. The structure of the crystals helps them resist fracturing.
