At present, our most preferred filling material is Composite Resin. A Composite resin is a tooth coloured resin material. After tooth decay is removed, this material is layered into the tooth. Each layer is cured with a high intensity blue light and the final surface is shaped and polished. The final filling is virtually invisible as it matches with the colour of your teeth.
What is a dental restoration or filling?
- A dental restoration is also called a filling.
- It is done to repair a damaged or decayed tooth, restoring it back to its normal shape, size, appearance & function.
Why should a damaged or decayed tooth be restored?
- A tooth is repaired to protect the part of the tooth that has become exposed by the decay or injury.Restoration can prevent the loss of a tooth, since decay may spread and destroy the tooth.
- Restoration permits normal eating and chewing.
- Restored done on the front teeth, fillings improve, the appearance of teeth and the face.
What are the available materials dental restorations filling?
- There are different types of dental restorations which are used in various situations.
An amalgam is an alloy or combination of two or more metals.Amalgam fillings (silver fillings) are made up of mercury, powdered silver and tin. They are mixed and packed into cavities in teeth. It hardens slowly, and replaces the missing tooth substance. Amalgam fillings are held in place by the shape of the prepared cavity.The cavity has to have an undercut to prevent the filling from falling out. The amalgam is then packed slotted into the cavity.It is still commonly used, despite an ongoing debate about mercury toxicity.However we do not recommend it to our patients.
Bonding Or Composite Restoration
- Composite resin is a plastic tooth-coloured material that is used as a filling. It is also called a white or plastic filling. The process of fusing the filling material to the tooth is called bonding.
- It is placed into the cavity in layers until the tooth is restored to its original form.
- An ultraviolet light is used to harden it, and it can be chewed on immediately after it has been completed. This is an advantage it has over amalgam. The filling bonds or sticks to the tooth.
- This characteristic is a major advance for dentistry. There is no longer the need to cut a slot into a tooth to hold a filling in place, as is necessary for an amalgam filling. As a result, less tooth needs to be cut away for a filling.
- It is hard wearing and is used for repairing front and back teeth.
- Bonding is ideal for front teeth that need cosmetic.
