Tooth enamel

The tooth enamel is the most mineralized and hardest material of our body. The tooth enamel is one of the three important parts of the tooth, the other two being: the dentin and the cementum of the root.

The tooth enamel is the visible surface of the tooth, which is supported by the dentin from the inner side. The 96% of the enamel is made up of minerals; the rest is water and organic material. Since the enamel is transparent, the colour of the dentine significantly determines the colour of the enamel. The colour of the enamel can vary from light yellow to greyish-white. Its thickness varies on the total surface of the tooth. It is usually the thickest on the grinding part of the tooth (max 2,5 mm) and it gets thinner towards the gums, until it reaches the cementum – enamel meeting point.

The caries are generated by acid producing bacteria that use the food we consume. The acid attacks the enamel and it leads to the loss of important mineral materials. The minerals lost in the acid attack can be substituted by minerals transported by the saliva, fluoride helping also in the strengthening of the enamel.

Because of caries, tooth fillings may also be necessary.
