In recent years, bonding has proven to be a highly effective treatment for closing spaces between the teeth. Composite resin, a plastic material, is applied to the teeth to make them wider in areas where gaps exist. Bonding can also be used to close a space temporarily - until crowns are made, for example. On the other hand, if you are having your spaces closed through orthodontics, even if some of your teeth are too dark, bonding can be used to lighten them while the spaces are being closed.
If you are closing gaps with bonding, you should also consider taking care of any other visible defects, such as rotated or broken teeth, at the same time. As in most esthetic problems, computer imaging can help show you how many teeth will need treatment. Also, remember that gum disease or bone loss must be treated before bonding takes place. The only exception to this rule is when Dr. DelCastillo believes that the loose teeth need to be splinted together.
