What is Filling
A filling is a way to restore a tooth damaged by decay back to its normal function and shape. When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out the cavity with a filling material. By closing off spaces where bacteria can enter, a filling also helps prevent further decay. The teeth filling treatment in Chennai uses materials like gold, porcelain, a composite resin (tooth-coloured fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc). Fillings done are strong and cannot be chewed. Mostly patient prefers tooth-coloured fillings (composite resins) which also uses a laser beam that adds up to additional support and completely removes the bacteria without affecting much of the dental cleaning cost in Chennai.
Types of Filling:
- Gold fillings are made to order in a laboratory and then cemented into place. Gold inlays are well tolerated by gum tissues and may last more than 20 years. For these reasons, many authorities consider gold the best filling material. However, it is often the most expensive choice and requires multiple visits.
- Amalgam (silver) fillings are resistant to wear and relatively inexpensive. However, due to their dark colour, they are more noticeable than porcelain or composite restorations and are not usually used in very visible areas, such as front teeth.
- Composite (plastic) resins are matched to be the same colour as your teeth and therefore used where a natural appearance is desired. The ingredients are mixed and placed directly into the cavity, where they harden. 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 are called inlays or on lays and are produced to order in a lab and then bonded to the tooth. They can be matched to the colour of the tooth and resist staining. A porcelain restoration generally covers most of the tooth. Their cost is similar to gold.
