Types Of Teeth Filling Materials
A tooth filling usually becomes necessary when a cavity develops in the enamel of the tooth. This occurs because of tooth decay which is the result of not properly brushing your teeth. It is necessary to have a tooth filled. In this procedure, the filling material, which generally considered as one of dental supplies
, is a must. Nowadays, there are many types of material in the market. Let's take a brief look at them:
Gold fillings--These are made to order in a laboratory and then cemented into place. Gold inlays are well known by the duability. It can last at least 10 to 15 years, usually longer and doesn' corrode. One more thing, It can tolerate chewing forces. For these reasons, many authorities consider gold the best filling material. However, it is often the most expensive choice and requires multiple visits. Besides, a gold filling placed immediately next to a silver, amalgam filling can cause a sharp pain (galvanic shock) to occur. It may also happen that the interaction between the metals and saliva causes an electric current to occur - it's a rare occurrence, however.
Amalgam (silver) fillings--They are resistant to wear and relatively inexpensive. However, due to their dark color, they are more noticeable than porcelain or composite restorations and are not usually used in very visible areas, such as front teeth.
Tooth-colored composite fillings--The shade/color can be closely matched to the color of existing teeth and is particularly well suited for use in front teeth or visible parts of teeth. Besides, they actually chemically bond to tooth structure, providing further support to the tooth. In addition, composite fillings can also be used to repair chipped, broken or worn teeth. Composites may not be the ideal material for large fillings as they may chip or wear over time. They can also become stained from coffee, tea or tobacco, and do not last as long as other types of fillings generally from three to 10 years.
Porcelain fillings--This kind of fillings are called inlays or onlays and are produced to order in a lab and then bonded to the tooth. They can be matched to the color of the tooth and resist staining. A porcelain restoration generally covers most of the tooth. Their cost is similar to gold.
These are the most often used fill materials. Of course we have some other types of them, but they are not playing an important part in dental area.
If decay or a fracture has damaged a large portion of the tooth, a crown, or cap, may be recommended. Decay that has reached the nerve may be treated in two ways: through root canal endodontic
(in which nerve damaged nerve is removed) or through a procedure called pulp capping (which attempts to keep the nerve alive).
