composite repair is a conservative dental procedure that fixes a defect in an existing composite (tooth-colored) restoration rather than replacing it entirely. It commonly addresses chips, small fractures, worn edges, and localized staining or gaps at the margins. It is used on fillings, bonded buildups, and some cosmetic composite work on front and back teeth. The goal is to restore form and function while preserving as much healthy tooth structure as possible.

repair of restoration means fixing a small defect in an existing dental filling, crown, veneer, or other restoration instead of replacing the entire piece. It commonly involves adding or bonding new restorative material to the old material and tooth structure. It is used when damage is localized, such as a small chip, a worn spot, or a minor gap at the edge. It is often part of “minimally invasive dentistry,” aiming to preserve as much natural tooth and existing restoration as practical.

plaque retention (surface) describes how easily dental plaque can stick to, build up on, and remain on a surface in the mouth. It is influenced by surface texture, shape, and how easy the area is to clean. Dentists consider plaque retention (surface) when evaluating teeth, restorations, orthodontic appliances, dentures, and implants. It is commonly discussed when planning fillings, crowns, polishing, and hygiene strategies.

roughness describes how uneven a surface feels or measures at a very small scale. In dentistry, it can refer to the surface texture of teeth, fillings, crowns, dentures, and implants. Some roughness is intentionally created to help materials bond. Unwanted roughness is often reduced to improve comfort, hygiene, and appearance.

groove retention describes how well a dental material stays bonded inside the natural grooves (pits and fissures) of a tooth. It is most commonly discussed with fissure sealants and flowable resin composites placed on chewing surfaces. It also applies to small preventive or minimally invasive repairs where material is placed into shallow grooves or prepared channels. Good groove retention helps the material remain in place under chewing forces and moisture exposure.

slot retention is a mechanical way to help a dental restoration stay in place by creating a small “slot” or groove in tooth structure. It is most commonly discussed in operative dentistry when placing fillings, especially in areas with limited natural undercuts or reduced enamel. The slot acts like a tiny track that increases resistance to the restoration being pulled out or shifted by chewing forces. Dentists may combine slot retention with adhesive bonding, depending on the material and the clinical situation.

A pin-retained restoration is a dental restoration that uses small metal pins placed into dentin (the inner tooth structure) to help hold a filling or core in place. It is typically considered when a tooth has lost a large amount of structure and needs added mechanical retention. The pins act like anchors inside the tooth to support restorative material built around them. It is most commonly discussed in the context of large posterior (back tooth) repairs and foundation (“core”) build-ups.

burnishing is a technique where a dentist smooths, presses, or polishes a dental material or metal surface using a rounded instrument. It is commonly used to improve how a restoration adapts to the tooth and how smooth its surface feels. burnishing is often discussed with amalgam and gold restorations, metal margins, and matrix bands used during fillings. In some cases, similar “surface smoothing” steps are also used with resin-based materials before final finishing and polishing.

amalgam carving is the shaping of a freshly placed dental amalgam filling before it fully hardens. It recreates the tooth’s natural grooves, cusps, and contact points so the bite feels normal. It is most commonly used for silver-colored fillings in back teeth (molars and premolars). It is a step within the overall dental filling process, not a separate treatment.
