To date, filling remains the most common way to restore teeth. It is rare to find a person without a single tooth sealed, even to 25 years. The seal – this is the material that is used to fill the cavity in the tooth, which is formed as a result of the treatment of caries as well as mechanical damage. The main objective of the seals in addition to the aesthetic – the isolation of sensitive tooth structure from various germs and bacteria. Different fillings to each other mainly by parameters such as the appointment of (the use of the term: the temporary and permanent) material and workmanship.

The difference between the temporary and permanent fillings

Permanent seal set after caries treatment for closure of tissue from the saliva, food and microorganisms. In addition, the natural shape of the tooth is restored, it is important not only from an aesthetic point of view but also because the tooth, with the lost volume can not fully participate in the chewing and closing of the jaws, which can lead to negative changes in occlusion. This is why the seals carefully grinded and polished to restore the natural form.  Despite the name, even the most reliable permanent filling can serve up to 10 years. Temporary filling takes place in multistage dentistry. Most often, you must:

  • in the treatment of root canals during which the need to lay the drug for several days;
  • when the treatment of the tooth is held in several sessions;
  • in preparing dental Position tabs, which is manufactured for several da.

The temporary seal is designed for up to two weeks, it is cheaper, faster to install and can be easily removed after fulfilled its function. But at the same time, as both permanent seal, protects the tooth in the short term. 

Types of permanent seals

Another difference is the material of manufacture of seals. Popular early variety of metal alloys is now hardly used, because of the large number of deficiencies (high thermal conductivity, low aesthetic effect). Dentists also abandoned plastic seals, as they are toxic and harmful enough strong. Cement, as the material of the seal is not able to mimic the density and color of natural teeth, and requires a significant turning healthy tooth.

Most high-quality fillings are made of composite materials. They provide the most aesthetic and protective seals. Such seals are represented by two main types: chemical and light.

Chemical seal is so named because of its solidification requires a chemical reaction. Light seal hardens when exposed to light special dental lamp.

Features and advantages photopolymer fillings

A more accurate name seals, which harden when exposed to light – photopolymer seal. This material allows the dentist to accurately reconstruct the shape of the tooth, as it begins to freeze only under the influence of the lamp. Despite the strength and reliability of the material, seals follow to change every five years. Despite the high quality photopolymer fillings, for the restoration of the front teeth, dentists recommend ceramic inlays, which are much stronger and almost invisible.

Complications after installing seals

Most often, patients complain of pain under seal. The pain is the norm during the day post treatment. But if the pain persists, the reason for this may be substandard treatment of cavities that require re-treatment. Loss seals – another very common nuisance. If the seal has dropped out much earlier expiration of its service life, it speaks only of a medical error.

УDental care after installing seals

Special care is not required to seal the teeth, but we can not forget about the standard of hygiene procedures. Dentists also recommend visiting procedure professional oral hygiene several times a year. Also, be aware that the seal material is more porous than enamel, so it absorbs more of the coloring pigments, drinks and food that requires additional cleaning teeth post their use.
