Strongly built, well anchored
Teeth have different tasks: the incisors help to separate the food. The canines are used to bite off chewy foods, these are the strongest teeth with the longest roots and crowns. The front small back teeth (premolars) hold the food and chop it roughly, and the large rear molar teeth have the task of grinding food completely. They have to bear the greatest pressure of chewing and are anchored by a number of branching roots.
Natural teeth are built correspondingly well. Enamel, the outermost layer of the tooth crown is composed of the hardest substance in the human body. The main components are calcium phosphate and calcium carbonate, which achieves its special hardness from the incorporation of fluorine.
The gum protects the sensitive tooth neck and holds the tooth in the jawbone. The body’s own saliva acts as a natural detergent, firstly rinsing away bacteria and food particles and secondly forming a protective layer – the pellicle as it is known – with its enzymes and thus keeping harmful bacteria at bay.
