At the thought of a dental office, many still shudder and frown. Fortunately, the dental clinics of the new generation are radically different from the state polyclinics of our childhood. If you come to treat the teeth, the doctor will not only painlessly hold all the procedures and you can at this time calmly listen to music or watch TV. You will be asked in advance to discuss what seal to put. Today you can choose dental fillings for almost any taste and purse.
What are the seals?
There are several types of dental seals, in each clinic you can choose the option that suits you:
- Fillings from silicate cements. These seals are among the cheapest. They have a relatively low strength, are quite toxic. But there are seals and several advantages: a sufficiently high adhesion to hard tissues of the teeth, prolonged release of fluoride.
- Metallic filling materials. What are the advantages of this type of filling: they can last for decades, they take any chewing load. The danger is that the seal can change the color of the tooth or lead to a splitting of the tooth wall. The greatest disadvantage of this seal is the released mercury vapor.
- Composites. Allow the restoration of the tooth at the highest level. Material for a dental seal of this kind is applied in layers, each layer is polymerized by a special lamp. The service life of this type of dental fillings is up to 5 years, the cost depends on the number of materials used.
- In order to eliminate large defects in the teeth, doctors use special tabs . An insert is a preliminarily modeled seal that the dentist pastes into the tooth cavity. These tabs are made from ceramics, which allows you to choose the color that is the most identical to the color of tooth enamel.
