The dental bonding procedure utilizes a composite resin and is used for a variety of structural as well as cosmetic purposes. One can draw a parallel between dental bonding materials and a sculptor's clay. By using dental composite resin bonding your dentist can restore chipped or broken teeth, fill in gaps and reshape or recolor your smile.
A very mild etching solution is applied to your teeth to create very small crevices in the tooth's enamel structure. These small crevices provide a slightly rough surface permitting a durable resin to bond materials to your teeth. The resin is then placed on your tooth and high-intensity light cures the resins onto your tooth's surface - with each individual layer of resin hardening in just minutes. When the last coat has been applied to your tooth, the bonded material is then sculpted to fit your tooth and finely polished.
The resin comes in many shades so that we can match it to your natural teeth. Due to the layers involved, this procedure will take slightly longer than traditional silver fillings because multiple layers of the bonding material are applied. Typically bonding takes an hour to two hours depending on your particular case.
Esthetics is the big advantage over silver fillings. As silver does not stick to teeth, entirely healthy tooth structure is usually removed to keep a silver filling in place. Composites permit your cosmetic dentist to remove only the decayed area of your tooth. Unlike silver fillings, composite bondings expands just like your teeth and are much less likely to cause cracks in your tooth. Composites bond directly to the tooth providing support. Composites can be used to fill in cracks, chips and gaps - and will match the color of your other teeth.
Bonding with composites simply costs more in material and time.
