Humans were filling teeth thirteen thousand years ago
Paleolithic Italy shows bitumen packed into a tooth some 13,000 years back; Neolithic Slovenia sealed a crack with beeswax about 6,500 years ago. Pliny already mentioned fillers for hollow teeth. Modern dentistry still splits the job into preparing space and placing material—only the toolkit changed.
Restorations rebuild form and function after decay, trauma, or wear, and they can also seal around implants or follow root-canal therapy. Direct fillings are shaped inside the mouth; indirect restorations are made outside and then cemented. Preparation usually means cutting with rotary burs, lasers, or air abrasion—or hand instruments in atraumatic techniques—to clear unsound tissue and create retention shape. When a permanent fix cannot finish in one visit, temporary materials protect the prepared tooth until the next appointment.
The ready cavity is simply called a tooth preparation. Materials in common use include gold, amalgam, dental composites, glass ionomer cement, and porcelain. Designs are intracoronal when they hold material within the crown’s footprint, as with many amalgam or composite cavities and inlays, or extracoronal when coverage wraps outside the remaining tooth. For the most part, how far decay has tunneled determines how much structure must be removed and which material can honestly replace it without further fracture.
That long arc—from bitumen and beeswax to bonded composites—shows restoration as a recurring human bargain: sacrifice a little sound enamel to stop a larger collapse. Every generation reopens the same mechanical problem with newer chemistry, yet the two-step logic of prepare-then-fill remains recognizably ancient. Clinical choices still trade durability, cost, appearance, and how much healthy tissue must be cut away before the repair can hold under chewing force.
