What does preparation for a veneer mean?
A veneer is a thin shell of ceramic, often around half a millimetre, bonded to the front of a tooth. To make room for it, the dentist may remove a thin layer of enamel from the front surface. This is called preparation. How much is removed depends on what the veneer needs to change: the colour, the shape, the length or the position of the tooth.
The aim is to stay within the enamel wherever possible. Enamel bonds very well to ceramic and keeps the tooth strong. Going deeper, into the dentine underneath, weakens the bond and makes the tooth more sensitive, so a careful plan avoids it.
What is the difference between prep, minimal-prep and no-prep veneers?
| Type | How much tooth is removed | Suits |
|---|---|---|
| No-prep | None, or only polishing | Small, worn or spaced teeth; teeth turned slightly inwards |
| Minimal-prep | Usually 0.3–0.5 mm, within the enamel | Most colour and shape changes on teeth of normal size |
| Conventional prep | Up to about 0.7 mm, sometimes more at the edge | Darker teeth, larger changes in position or length |
Most smiles fall in the middle group. The amount differs from tooth to tooth in the same smile: a tooth that already stands back may need nothing, while its neighbour that stands forward needs a little more.
When do no-prep veneers work well?
When there is space to add. Teeth that are small for the face, worn short from grinding, separated by gaps, or set slightly back can receive a veneer without any drilling, because the new shape is built outwards. The result can be natural, and the tooth underneath stays almost untouched.
No-prep veneers also suit people who want to keep the option of going back to their natural teeth, although even then the surface is etched for bonding, so the change is not fully reversible.
When do no-prep veneers look bulky?
On teeth of normal size and position, adding half a millimetre of ceramic without making room makes the teeth thicker. The lips can feel pushed forward, the teeth can look too white and too wide, and the edge at the gum can trap plaque. This is one reason why a smile can look artificial even when the veneers themselves are well made.
The digital preview before treatment helps here. You see the planned shape on your own face, and the doctor shows where a tooth needs a little preparation to stay natural in thickness.
Are veneers the same as “Turkey teeth”?
No. Many photos labelled “Turkey teeth” show crowns, not veneers. A crown covers the whole tooth, so the tooth is shaped down on every side, often by one to two millimetres, sometimes to a small peg. That removes far more natural tooth than a veneer and can lead to sensitivity, nerve problems and root canal treatment later.
Crowns have their place, for example on teeth that are broken, heavily filled or root-treated. For healthy front teeth where the aim is colour and shape, veneers or bonding usually keep much more of the tooth. Our guide on Turkey teeth explains how to tell the two apart in a quote.
How do we decide how much preparation a tooth needs?
The plan starts from the result, not from the tooth. After a 3D scan and photos, the doctor and ceramist design the new smile digitally and you see it on your face. A trial version, called a mock-up, can then be placed over your teeth so you see and feel the shape before anything is changed.
Only where the planned shape sits inside the current tooth is enamel removed, and only as much as needed. The ceramist works with these measurements in our lab next door, so the thickness of each veneer matches the plan.
Is composite bonding an alternative?
Often, yes. Composite bonding adds tooth-coloured resin directly to the tooth, usually without any preparation. It costs less and can be repaired easily, but it stains and wears faster than ceramic, so it usually needs polishing or renewing after some years. Our guide on veneers or bonding compares the two.
What should the plan tell you before you agree?
- Which teeth receive veneers, and which material
- For each tooth: no preparation, minimal preparation, or more, and why
- Whether any tooth needs a crown instead, and why
- A digital preview, and if possible a mock-up, before preparation
- Who makes the veneers, and whether a try-in is included
