Bonding is a broad term used in modern dentistry that refers to the joining together securely of a filling material and the tooth with an adhesive substance. Bonding allows the new, tooth like structure to fuse with the tooth, essentially making the new material and the natural tooth one strong almost natural structure. Recent advances in the materials, techniques and adhesives have increased the strength, durability, appearance and the longevity of these tooth colored restorations to offer the modern dentist more options than ever before to help patients fulfil their dental needs.
