The animals of the lower species are changing their teeth throughout life. When the teeth reach full development and when they become worn, they fall out and grow in their place new.
However, the man changes his teeth only once in a lifetime. Therefore, it is important to keep your teeth and keep them from failure. The teeth usually begin to decay on the enamel. It can be almost invisible hole, but because in the mouth there are always bacteria, they quickly penetrate through the hole on the surface and settle down under the enamel.
They can not eat the enamel, but they can eat dentin, which is softer, and lymphoma, which is located in the channels of dentin. Bacteria soon eroding the canal walls and beneath the enamel creating a cavity.
Damage can remain undetected for some time, but when, due to the work of bacteria, wall tooth has thinned, then we will notice very quickly. Then the heat and cold can quickly penetrate to the pulp cavity. The pulp occupies a cavity in the central part of the tooth and contains nerves. Heat and cold irritating the nerves. When a tooth has become sensitive to hot or cold; that is alert!
When bacteria penetrate the dentin channels in the pulp cavity, they find an excellent template for nutrition and growth. Then we get a toothache. Tooth decay continues, the network of channels that supply food tooth decay. And tooth, because no longer receives food, it becomes a dead shell. The lesson: go regularly to control!
