Medical Encyclopaedia › Veneers (short definition)
In brief: Veneers are wafer-thin facing shells that are bonded to the front of teeth, usually in the visible front tooth area. They can correct colour, shape, small gaps or slight misalignments. Because tooth enamel is often removed for them, the decision is often irreversible.
Types of veneers
- Ceramic veneers: made in the laboratory, usually from glass ceramic; colour-stable, very aesthetic and durable, but more elaborate and expensive. If one breaks, the veneer usually has to be replaced.
- Composite veneers: made of tooth-coloured resin, often modelled directly in the mouth in one session; cheaper and easy to repair, but more prone to discoloration and wear.
- No-prep or minimal-prep veneers: very thin shells for which little or no enamel is removed; only possible if the starting situation is suitable, otherwise the teeth quickly look too thick.
Who are veneers suitable for?
Typical reasons are discolorations that cannot be bleached, chipped corners, worn incisal edges, shape deviations such as small or pointed teeth, and smaller gaps. Prerequisites are healthy teeth and gums and sufficient enamel for bonding. With pronounced teeth grinding, a deep bite, large fillings or severe misalignments, veneers are unfavourable; orthodontic treatment, for example with aligners, or crowns are more likely to be considered here. It is often worth checking first whether bleaching or small composite corrections are already sufficient.
Procedure
After examination and consultation, the desired result is often first simulated with a wax model and a trial restoration in the mouth (mock-up). For ceramic veneers, the tooth surface is usually ground down by a few tenths of a millimetre, followed by an impression or a digital scan; temporary shells are worn until fabrication. When fitted, the veneers are permanently bonded to the enamel using the adhesive technique. Composite veneers, by contrast, are built up layer by layer directly on the tooth.
Durability and risks
According to studies, well-planned and well-fitted ceramic veneers often last many years; composite veneers usually need repairs or replacement sooner. Possible problems are:
- irreversible loss of tooth enamel due to grinding
- chipping, fracture or debonding of the shells
- discoloration at the margins, caries at the junction with the tooth
- tooth sensitivity after grinding
- gum irritation with unfavourably designed margins
- an unnatural-looking result with veneers that are too thick or too light
Professional bodies view very extensive treatment of many healthy teeth for purely aesthetic reasons with heavy grinding or crowning critically, because healthy tooth substance is lost and follow-up treatments become more likely.
Care, costs and important to know
Veneers are cared for like natural teeth; regular check-ups and professional tooth cleaning are important. In people who grind their teeth, a night-time occlusal splint can protect the shells. Veneers are usually a private service; German statutory health insurance at most covers the fixed subsidy for a comparable standard treatment if there is a medical necessity. A written treatment and cost plan, a detailed consultation and sufficient time to reflect are particularly important before a treatment that is hardly reversible.
