Dental bonding is a procedure carried out for repairing chipped off or broken teeth using white filling made out of a composite material which is quite close to the natural tooth color. Bonding is also done to make composite veneers; changing tooth shapes for particular cosmetic appearances, and to fill any gaps and spaces between teeth. This is a technical procedure that needs the skills and expertise of your Liverpool dentist for completion.

Composite “white” fillings

Bonding is favored by most Liverpool dentists over amalgam fillings used earlier as it is closest to the natural tooth color and gives a natural effect rather than appearing prominently artificial. Tooth fillings which have been done using old filling materials are now often replaced by Liverpool dentists with natural tooth shade white fillings. Compared to other filling materials not all composites are as strong and hence every composite cannot be used for bonding. Since bonding cannot bear much force hence they are usually applied to small filling areas. However most Liverpool dentists are now inclined to used technologies like CAD/CAM CEREC which offer not only aesthetics but also strength and durability through ceramic filling materials.

Composite Bonding

The first step in the bonding process involves numbing the surrounding gum area by injecting it with an anesthetic. Following it is the tooth cleaning process which means removing any tartar or wastes as the composite bonding requires a perfectly clean surface for effective bonding. The Liverpool dentist then chooses the closes match for the tooth shade in the composite bonding that will be applied and ensures that the tooth which is being treated is absolutely dry. The dentist may use latex sheets or cotton rolls to absorb any liquid or saliva and will use a drill to shape the tooth.

The dentist will use a conditioner with a base of phosphoric acid to etch the tooth surface which needs to be bonded. This will give the tooth surface the texture required for good bonding. The tooth surface is then applied with the bonding agent /composite in layers of 1-2 mm each until the desired result is achieved. To harden this composite a special source of light is beamed at it which as a result hardens the bonding agent and sets it into place. At the end, the surface is buffed and polished for the final touches and smoothness. These fillings that last around 5-10 years are less durable and more prone to staining than other materials used in tooth restoration such as porcelain or ceramic.
