A dental filling is a way to rebuild a damaged or decayed tooth to its normal function and shape. When you require a dental filling, the dentist will first remove the decayed tooth material. After cleaning the damaged area, he will fill the cleaned-out cavity with a filling material. Dental fillings are also used to restore cracked or broken teeth and teeth that have been worn down from misuse like nail-biting or tooth grinding). And by closing off the spaces where there is a possibility that bacteria can enter, a filling also helps prevent further decay. The materials used for fillings are gold, porcelain, a composite resin (colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin, or sometimes zinc).
Types of Dental Filling:
There are various forms of fillings, and no universal model of filling suits to everyone. Factors like the extent of the repair, whether you have allergies to certain materials or not, the area needs to be filled, the cost, etc. determine which filling is best for you. And if decay or a fracture has damaged a large portion of the tooth, a crown, or cap, may be recommended.
The various types of fillings are as follows:
- Gold fillings are prepared in a laboratory and then cemented into place. Gum tissues well absorb gold inlays and last more than 20 years. For these reasons, it is considered as the best filling material. Still, it is the most expensive choice and requires multiple visits.
- Amalgam (silver) fillings are reluctant to get bonded and relatively inexpensive. However, they are vividly visible. They are not used in distinct areas, such as front teeth.
- Composite (plastic) resins are matched with the natural teeth color and used where a natural appearance is required. But it may not be the ideal material for large fillings, as it may chip or wear over time. And also become stained from coffee, tea or tobacco, and do not last as long.
- Porcelain fillings, also called Inlays or Onlays and are prepared in a lab and then bonded to the tooth. They come like the natural tooth color whose cost is similar to gold.
