Cosmetic Dental Bonding
Introduction to Dental Bonding
The dental bonding procedure utilizes a composite resin and used for a variety of structural as well as cosmetic purposes. One can draw a parallel between dental bonding materials and 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.
How is tooth Bonding Accomplished?
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'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 materials are applied. Typically bonding takes an hour to two hours depending on your particular case.
Types of Tooth Bonding Procedures
There are two types of bonding. What type is indicated in your situation depends upon whether you have a small area or a larger area that requires correction.
For Small Corrections
These are on appointment fillings which are color-matched to the tooth and are bonded to the surface for added strength. These are most appropriate for small fillings and front fillings as they may not be as durable for large fillings.
For Larger Corrections
Dental lab-created tooth-colored fillings require two appointments and involve making a mold of your teeth and placing a temporary filling. A dental laboratory then creates a very durable filling to custom-fit the mold made from your teeth. These fillings are typically made of porcelain. The custom-fit filling is the then bonded to your tooth on your return visit. This type is even more natural looking, more durable and more stain resistant.
Who is a candidate for Tooth Bonding?
If you have close, small gaps between your front teeth, or if you have chipped or cracked teeth, you may be a candidate for bonding. Bonding is also used for patients who have discolored teeth, uneven teeth, gum recession or tooth decay. Bonding material is porous, so smokers will find that their bonding will yellow. If you think you are candidate for bonding, discuss it with your dentist.
Pros and Cons of Tooth Bonding
Advantages of dental bonding:
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 can be used to fill in cracks, chips and gaps - and will match the color of your other teeth.
Disadvantages of the dental bonding procedures:
Bonding with composites simply costs more in material and time.
