Filling is a way to restore a tooth damaged by decay back to its normal function and shape.
Decay causes a “hole” on your teeth or causes space in between your teeth. It is important to get a filling done in the initial stage; before the cavity becomes deeper and causes pain, in order to avoid more complex and more expensive procedures. When a dentist restores your tooth, he or she will first remove the decayed tooth material, cleans the affected area then fill up the cleaned out cavity with a filling material. By sealing off spaces where bacteria can enter, a filling also helps prevent further decay. Many types of materials can be used for fillings. The common ones are called composite resins and glass inomer cements which are both tooth colored.
Inlays & Onlays: - Inlays or Onlays are used to restore teeth with mild to moderate decay, or teeth that have cracks or fractures that are not severe enough for a crown. They can also be used to replace metal fillings.Inlays are used to restore teeth where the decay or damage is within the indented top surfaces.Onlays are used to restore teeth where the decay or damage extends to the cusp of the tooth or beyond.
Dental inlays or onlays are made from porcelain, composite resin or gold.Inlays and Onlays are a two step process because they are fabricated by a laboratory using the impression taken by your dentist. You will be fitted with a temporary inlay or onlay while you wait for the finished restoration to return. Because they are customised to your tooth, they can be more securely bonded to the tooth surface, adding structural integrity and preventing bacteria from entering and forming cavities.
