Dental fillings are among the most popular cosmetic dentistry procedures that are being used these days in order to promote tooth restoration and general oral appearance. If you are thinking about getting dental fillings for yourself, below are some of the basic facts that you should know.
How are dental fillings placed on your tooth?
Your dentist will recommend dental fillings if you have slightly discolored teeth or if you have minor tooth damages such as chips. If you opt for this process, your dentist will first prepare your tooth for the procedure. He will probably inject a local anesthetic to your gums in order to numb the area where the fills will be placed.
Before the filling process, your dentist will have to make sure that your tooth is free from decays. He will conduct traditional drilling on your tooth, along with micro air abrasions. He will remove the deceased parts of your tooth and clean the decay area. After the area is cleaned, your dentist will then use a special dental tool to open your dentin. However, if the renovated area is near your tooth nerves, a special liner will be placed.
Once the tooth enamel is clean and exposed, the fillings are placed. The composite fills will be applied through layer by layer and a special light will be used to harden each of these layers. After the fillings are placed, the dentist will use an "articulating" paper to modify and "fine-tune" your dental filling. This filling will preserve and restore your natural tooth. However, if such is not enough to protect your tooth from further damage and decay, your dentist may also recommend the use of tooth crowns.
Two major types of dental fillings
Amalgam fillings are the traditional dental fillings that are being used in many dental clinics before. These dental fillings are made out of liquid mercury, silver, copper, and zinc. Over the years, it has been noted that such material are quite durable and hard-wearing. However, recent investigations made by the Food and Drug Administration (FDA) note that these metal fillings may pose hazards as mercury may be released from the amalgam.
Composite Resin Fillings
These dental fillings are made out of plastic resins. These types have achieved popularity and they have been a common alternative to metal fillings. Plastic resins are also quite durable and strong. However, what makes this type of fillings at a prime advantage over the metal ones is the fact that they do no pose any health risks. In addition to that, plastic resin take on a very natural look as they can be colored or tinted to blend the original color of a person's tooth.
