Bonded resin is a tooth-colored plastic used to repair decayed, chipped, or cracked teeth, close gaps, and change tooth shape. It is inexpensive, can be applied in one visit, and matches tooth color. However, it is less durable than other options and can chip or break.
Bonded resin is a plastic material used in reconstructive dental procedures. Resin is a tough, tooth-colored plastic that is bonded to your teeth. It is generally made from a composite of synthetic materials designed specifically to adhere to the teeth.
One use of bonded resin is to repair decayed teeth by filling cavities. It is also used to fix chipped or cracked teeth, close spaces between teeth, or generally change the size or shape of a tooth. Bonded resins are also used to protect the root of a tooth that has been exposed after the gums have receded. Some dentists find adhesive resin to be more appropriate for minor cosmetic changes, temporary cosmetic defects, and correction of teeth with low bite pressure such as anterior teeth.
Anesthesia is generally not used when applying bonded resin, except when it is used to fill a cavity. A dentist will use a shade guide to choose the resin color that most closely matches the natural color of the tooth. The tooth surface is then roughened and a conditioning material is applied to help the resin adhere to the tooth. The resin, in the form of a putty, is applied to the tooth, molded into the desired shape and smoothed. Next, an ultraviolet or laser light is applied to the resin, which usually contains a photoinitiator that causes the resin to harden. The resin is then trimmed, shaped and polished.
Synthetic resins have become a popular dental choice in recent decades as they are relatively inexpensive. Unlike other restorative options like veneers and crowns, which need to be customized and manufactured in a lab, resins can usually be fitted and applied in just one visit to the dentist. They are also insoluble, meaning they cannot dissolve and are not susceptible to dehydration. Composite resins can be modified and adapted to allow the material to match the color of your teeth, making them an aesthetically pleasing choice. Bonded resins generally last three to ten years.
Bonded resins aren’t as strong as other restorative options like veneers, crowns, and fillings, and generally won’t last as long. They are also less resistant to stains than other materials. Bonded resins can also chip and break, so patients receiving bonded resins are advised to avoid biting their nails, chewing on pens and other hard objects, and using their teeth to open things.
