A composite veneer is a thin layer of tooth-colored resin material bonded to the front surface of a tooth. It is used to improve the appearance of teeth by changing shape, color, or minor alignment. Composite veneer is commonly placed chairside (in one visit) using light-cured composite resin. It may also be made indirectly and bonded later, depending on the technique and case.
A porcelain veneer is a thin, custom-made shell that bonds to the front surface of a tooth. It is made from dental ceramic (“porcelain”), designed to mimic natural enamel in color and translucency. It is commonly used on front teeth to change appearance and, in select cases, to restore minor damage. It is typically fabricated in a dental laboratory or milled with CAD/CAM and then cemented in the clinic.
A veneer is a thin, tooth-colored covering placed on the front surface of a tooth. It is used to change how a tooth looks, and in some cases to restore minor structural loss. Veneer materials commonly include dental ceramics (porcelain) and resin-based composite. It is most often used on front teeth, where appearance and edge shape are easily seen.
A subgingival margin is the edge of a dental restoration that sits below the gumline. It describes *where* the restoration meets the tooth in relation to the surrounding gingiva (gum tissue). It is commonly discussed with fillings, crowns, onlays, veneers, and bridgework. Its placement affects cleaning access, gum health, and how well a restoration can be sealed.
An equigingival margin is a dental restoration margin placed at the same level as the gumline. It describes *where* the edge of a filling, crown, veneer, or bonding ends relative to the gingiva (gums). It is commonly discussed when planning restorations near the cervical (neck) area of a tooth. It helps clinicians balance appearance, cleanability, and tissue health around the restoration.
A supragingival margin is the edge of a dental restoration that sits above the gumline (above the gingiva). It describes a location, not a specific material. It is commonly discussed when placing fillings, crowns, inlays/onlays, veneers, and other restorations. Clinicians often aim for a supragingival margin when feasible because it can be easier to keep clean and to work on.
biologic width is the natural “protective space” of soft tissue that attaches the gum to the tooth above the bone. It includes the gum’s attachment and sealing tissues that help keep the underlying bone and periodontal tissues healthy. Dentists consider biologic width when placing fillings, crowns, veneers, or other restorations near the gumline. In everyday terms, it is the room your gums need to stay stable and not chronically irritated by dental work.
The ferrule effect is a design feature used when restoring a tooth with a crown, especially after root canal treatment. It describes how a ring (or “band”) of natural tooth structure above the gumline can help the restored tooth resist fracture. It is commonly discussed in treatment planning for crowns, post-and-core restorations, and heavily broken-down teeth. In simple terms, it’s the “tooth structure collar” that helps a crown hold onto the tooth more reliably.
A ferrule is a design feature in restorative dentistry where a crown or similar restoration encircles a band of natural tooth structure. In plain terms, it is like a supportive “collar” of tooth tissue that a crown can grip. It is most commonly discussed for teeth that have had root canal treatment and need a crown. Clinicians evaluate ferrule during planning for crowns, core build-ups, and post-and-core restorations.
crown lengthening (prosthetic) is a periodontal (gum) procedure that exposes more natural tooth structure above the gumline. It is commonly used before placing a crown or other restoration when there is not enough tooth visible to support a durable margin. It may involve reshaping gum tissue alone or both gum and the underlying bone, depending on the case. The goal is to create healthy, stable space for a restoration without impinging on the tissues that attach the tooth to the bone.
