When dentists are treating cavities, they remove the decayed part of the tooth and then fill the area where the decomposed material was removed. Fillings can also be used to repair cracked or broken tooth. Other teeth that can be fixed in a dental clinic are those that are worn-out due to misuses such as nail biting or tooth grinding. When filling a tooth, a doctor will use an anesthetic so as to numb the area that is around the tooth. This step is followed by the utilization of an air abrasion instrument or a drill to remove the decayed area. The choice of the device is determined by the dentist’s level of training, his comfort level, investment in the equipment and the extent of decay.

Testing the affected area
The dentist then tests the area to make sure that all the decayed material has been removed. After confirming, the doctor will then prepare the space for filling by thorough cleaning of the area to get rid of bacteria and other debris. If the decayed area is close to the root of the tooth, the dentist puts in a liner that is made of composite resin, glass ionomer, or another material to protect the nerve. Once the filling is in its right place, the doctor performs the final touches through polishing.
For tooth colored fillings, a different procedure is used. Once the area is cleaned and the decay removed, the tooth-colored material is applied in layers. A special light that is used to harden the layers is applied. Once the multilayering is complete, the doctor shapes the composite material to the desired size. Any excess material is trimmed off, something that is followed by polishing and the final restoration.

Types of fillings
Various materials are available in the market. A person can have his teeth filled using gold, silver amalgam, porcelain or a tooth-colored plastic. Glass ionomer is also used and it is a material that contains glass materials. Glass ionomer is used in the same way the composite resin fillings are used.
The type of filling is determined by the extent of the decay, the total cost of filling material, and insurance coverage.

Insurance cover
Some insurance plans cover the cost of composite fillings to the total price of silver fillings, and then the paid is requested to pay the difference.

Indirect fillings do resemble the tooth colored fillings or the composite fillings. The difference is that indirect fillings are made in the laboratory.
A person requires a minimum of two visits to the dental clinic before they are placed. Indirect fillings are recommended for people who do not have enough tooth structure which can support the filling. If you want to learn more, visit Your Smile Dental Care.
