Bonding - White fillings Manchester

Dental bonding is the use of a composite tooth coloured material in dentistry, which creates a strong bond with teeth. Bonding can be used for a variety of procedures including "white fillings", the repair of broken or chipped teeth, changing the shape of teeth, closing gaps between teeth (diastamas) and for producing composite veneers. Dental bonding is a very skilful and artistic procedure carried out by your dentist in Manchester.

Composite "white" fillings
Bonding is a popular choice for fillings because of it can match the shade of natural teeth and provides a better aesthetic result than old amalgam based fillings. Cosmetic dentists in Manchester often replace old fillings with tooth coloured composite. However not all fillings are suitable for bonding as the composite material is not as strong as other restorations. Bonding is best suited for small fillings that are not exposed to great forces. With recent advances in dental technology many dentists in Manchester are turning to the use of CAD/CAM CEREC technology to produce ceramic fillings, which have the advantages of both strength and aesthetics.

Your Manchester dentist will first numb the tooth concerned by injecting a local anaesthetic into the gum area around the tooth. The tooth surface is then thoroughly cleaned to remove any accumulation of tartar and debris as the composite needs a clean surface to bond to. Once the correct shade of composite is selected by your Manchester dentist the tooth is kept dry by surrounding it with cotton rolls or a latex sheet and then shaped by the dentist using a drill.

The surface of the tooth that will receive the bonding is etched with a phosphoric acid based conditioner, which provides a better surface for the composite to adhere to.  The composite (bonding agent) is then applied to the etched tooth surface and exposed to a special light source, which causes the composite to harden and set. The bonding agent is applied to the tooth in thin layers (1-2 mm) until the desired aesthetic result is achieved. The final step involves polishing and buffing of the composite to give the final desired shape and smooth finish. The main drawbacks of bonding are that it doesn’t have the strength of other restorative materials such as ceramic or porcelain and it has a greater tendency to stain than the surrounding teeth. Composite fillings typically last 5-10 years.
