Direct Composite Bonding
Direct bonding is a dental procedure in which a material called composite resin (dental plastic) is applied directly to the tooth to restore its appearance and function.
It is used not only for cavity treatment but also for cosmetic purposes, such as closing gaps between front teeth, repairing chipped teeth, correcting discoloration, and reshaping teeth.
Because it requires minimal removal of the natural tooth, healthy tooth structure is preserved as much as possible.
What is Direct Bonding?
Direct bonding is a procedure in which a special resin (composite resin) is applied directly to the tooth to shape it, and then hardened using light.
The treatment can be completed in a short time and requires minimal removal of the natural tooth, making it a gentle and conservative option for dental care.
