Bonding and Fillings
Bonding is a popular method to enhance the aesthetics of your smile. Bonding and fillings can be used to correct cracks or gaps in teeth, as a filling after a cavity has been removed, or to cover up stains or discolored teeth.
A composite resin is used on the affected tooth or teeth. It is molded and sculpted over an adhesive gel that is placed on the tooth. After the resin has been applied an ultraviolet light is used to harden the resin, which is then polished to give you a fresh, new smile. Bonding is an obvious improvement over unsightly silver amalgam fillings. With the advancements in dental technology, bonding usually lasts for over 10 years. It is a safe, affordable, and attractive solution for many dental problems.
For What Conditions Is Dental Bonding Considered?
Dental bonding is an option that can be considered:
- To repair decayed teeth (composite resins are used to fill cavities)
- To repair chipped or cracked teeth
- To improve the appearance of discolored teeth
- To close spaces between teeth
- To make teeth look longer
- To change the shape of teeth
- As a cosmetic alternative to amalgam fillings
- To protect a portion of the tooth’s root that has been exposed when gums recede
What Are the Advantages and Disadvantages of Dental Bonding?
Advantages: Dental bonding is among the easiest and least expensive of cosmetic dental procedures. Unlike veneers and crowns, which are customized tooth coverings that must be manufactured in a lab, bonding usually can be done in one office visit unless several teeth are involved. Another advantage, compared with veneers and crowns, is that the least amount of tooth enamel is removed. Also, unless dental bonding is being performed to fill a cavity, anesthesia is usually not required.
Disadvantages: Although the material used in dental bonding is somewhat stain resistant, it does not resist stains as well as crowns. Another disadvantage is that the bonding materials do not last as long nor are as strong as other restorative procedures, such as crowns, veneers, or fillings. Additionally, bonding materials can chip and break off the tooth.
How Long Does Bonding Material Last?
The lifespan of bonding materials for the teeth depends on how much bonding was done and your oral habits. Typically, however, bonding material lasts from three years up to about 10 years before needing to be touched up or replaced.
