Teeth have to do a lot. They should meet the daily requirements and for as long as possible a lifetime. The chewing pressure that a tooth has to withstand can amount to as much as 300 kilos for women and up to 400 kilos for men. In addition to the pure chewing function, our teeth also have a social function. A radiant smile and a flawless pronunciation depend very much on an intact dentition. Despite regular dental care, tooth decay bacteria can still destroy the teeth.
Once the hard tooth substance has been attacked, only the "repair" remains. To save the affected tooth, the dentist removes the diseased tissue and fills the cleaned hole (cavity). Thanks to modern materials and developments in dentistry and dental technology, there are now a variety of different materials and techniques. Which material is most suitable depends on various factors such as size and location of the defect and must be determined in a single case. Frequently, different materials are available for repair, which differ in their properties and the price. Prodente gives below an overview of the most common fillings and methods.
The materials can first be roughly subdivided into soft and hard fillings. Soft fillings made of amalgam or composite are best for small and medium sized defects. They are introduced by the dentist directly into the cavity and harden then in the mouth, or in the tooth, from:
Amalgam is a liquid, malleable or solid alloy. For dental purposes, so-called "alloys", that is powders of silver, copper or tin are mixed with mercury. Due to the dark metallic color, amalgam is usually not used in the anterior region. Because of its high resilience and an optimal conclusion to the tooth substance it ensures but especially in the molars a high durability. It has been used for more than 100 years. Due to its mercury content of this filling material is controversial. But even after countless and long-lasting tests and experiences, it is classified as harmless.
Today, composites are only 20 percent plastic. Therefore, the term "plastic filling" is actually misleading. The embedded fillers, such as glass ceramic and quartz particles make up today by far the greater part of this material. After insertion into the tooth composite fillings cure by the use of blue light in the tooth. As a rule, they are universally applicable and also correspond in their color to the aesthetic requirements. Today, the new plastics can easily withstand the mechanical requirements of chewing and are therefore used as an alternative to amalgam as required or at the request of the patient. Due to the higher degree of shrinkage during curing, however, microcracks can cause problems in the transition from the filling to the tooth.
Temporary filling materials
Temporary filling materials are all types of cement with which a tooth can be supplied for a short time. Temporary fillings are made from materials that are easy to insert into the tooth and can be removed again. They should only last for a short time and are then exchanged for a permanent filling.
