amalgam bonding is a technique that uses a dental adhesive to help attach an amalgam filling to tooth structure. It is most often used for back teeth where amalgam restorations (silver-colored fillings) are placed. The goal is to improve sealing and retention compared with relying only on traditional mechanical “lock-in” shapes. The term can also describe bonding procedures used when repairing or modifying existing amalgam restorations.

An amalgam restoration is a dental filling made from a metal alloy that includes mercury mixed with other metals. It is used to repair tooth structure that has been damaged by tooth decay (a cavity) or fracture. It is most commonly placed on back teeth where chewing forces are higher. It is a direct restoration, meaning it is shaped in the tooth during the appointment.

high-copper amalgam is a type of dental filling material made by mixing an alloy powder with mercury to create a packable restorative mass. It is called “high-copper” because the alloy contains more copper than older “low-copper” amalgams. It is most commonly used for restoring back teeth (molars and premolars) where chewing forces are higher. In everyday terms, it is a durable, silver-colored filling material used to repair decayed or damaged tooth structure.

amalgam is a dental filling material made by mixing a metal alloy powder with mercury to form a moldable mass. It is commonly used to restore back teeth (molars and premolars) after a cavity is removed. It hardens by a chemical setting reaction rather than by a light. It has a long history in dentistry and is still used in some practices and regions.

compomer is a tooth-colored dental restorative material used to fill or repair certain types of cavities. It is a resin-based material that also includes components associated with fluoride release. It is commonly used for small to moderate restorations, especially in lower-stress areas and in pediatric dentistry.

giomer is a tooth-colored, resin-based dental restorative material used to repair or protect teeth. It is designed to handle like composite resin while incorporating glass-ionomer–related filler technology. It is commonly used for small to moderate fillings, preventive restorations, and some sealant-type applications. Exact performance and features vary by material and manufacturer.

conventional glass ionomer is a tooth-colored dental material used to repair teeth and protect tooth surfaces. It is made by mixing a glass powder with an acidic liquid, forming a set (hardened) material in the mouth. It is commonly used for small restorations (fillings), linings/bases under other materials, and some types of cementation. It is often chosen when fluoride release and bonding to tooth structure are desirable.

mechanical exposure is an opening into the dental pulp (the tooth’s nerve and blood supply) caused by instrumentation or trauma rather than decay. It most commonly refers to an iatrogenic pulp exposure that occurs during cavity preparation, crown preparation, or removal of an old restoration. In simple terms, it means the pulp chamber was “accidentally uncovered” while working on the tooth. It is discussed in restorative dentistry and endodontics because the next steps focus on keeping the tooth sealed and healthy.

carious exposure means the tooth’s pulp (“nerve” and blood supply) becomes exposed because a cavity (dental caries) has progressed deeply into the tooth. It is most commonly identified during cavity removal or when a cavity breaks into the pulp chamber. Dentists use the term carious exposure to describe a specific clinical finding that can affect treatment planning and prognosis. In simple terms, it is “a cavity that has reached the tooth’s living center.”

pulp exposure is when the dental pulp (the tooth’s inner “nerve and blood supply” tissue) becomes open to the mouth. pulp exposure can happen from tooth decay, dental procedures, or trauma. pulp exposure is discussed in restorative dentistry and endodontics because the pulp needs protection from bacteria and irritation. pulp exposure is commonly identified during cavity preparation, after a fracture, or when a deep filling is removed.
