Bonding is the process whereby composites or porcelain/ceramic materials are fused to teeth. Composite is a tooth colored resin material composed of plastic with small glass or ceramic particles. It is usually cured with filtered light to repair small fractures or change the color or shape of a tooth.
The disadvantage of composite resin is that they are not as strong as porcelain and require repairs every few years. Composites can also discolor over time and does not have as much natural beauty as porcelain.
