The Age of Adhesive Dentistry is here! These images demonstrate various applications of Direct Bonding, which is a conservative, tooth-preserving option to cover cosmetic defects, recontour misaligned teeth, and close spaces with little or no tooth reduction or anesthesia. Another application of bonding is when failing silver amalgam fillings are replaced with bonded tooth-colored composites. This is also how most smaller decay areas are restored now in modern practice.
There are certainly situations where adhesive ceramic crowns or porcelain veneers are indicated for the best, most durable, and most aesthetic result. However, direct bonding is a great option for lots of cosmetic or decay issues that allows a simpler, less costly approach than full crowns or porcelain veneers.
