Dental veneers: types, lifespan and what to ask before you commit

Dental veneers are thin shells of ceramic, such as E.max, or of composite resin, bonded to the front of the teeth to change their colour, shape or length. With good care, ceramic veneers often last ten to fifteen years or more, while composite usually needs repair sooner. Before committing, ask about tooth preparation, alternatives and maintenance.

What veneers are and who they suit

A veneer is a thin layer of tooth-coloured material fixed to the front surface of a tooth. It works a little like a false fingernail: the tooth underneath stays in place, and the veneer changes what you see when you smile.

Veneers are a cosmetic treatment. A dentist will usually consider them for:

• teeth that are discoloured and do not respond well to whitening;
• chipped, worn or slightly broken front edges;
• small gaps between the front teeth;
• teeth that are slightly uneven, too short or irregular in shape;
• mild irregularities where the person prefers not to have the teeth moved.

Veneers are not a solution for every problem. Teeth with active decay, gum disease, very large fillings or a significant bite problem usually need other treatment first, and sometimes a crown is a better choice than a veneer. When several veneers are planned together to change the whole smile, the result is often called a Hollywood smile; our article on what a Hollywood smile really is, and what it is not explains this in more detail.

The main types of veneers

There are two main families of veneers. Each has its place, and the right choice depends on your teeth, your bite and your expectations.

Ceramic veneers (E.max and other porcelains)

Ceramic veneers are made in a dental laboratory from a thin but strong ceramic. E.max, a lithium disilicate glass-ceramic, is one widely used material. Ceramic resists staining well, reflects light in a way that is similar to natural enamel and usually lasts longer than composite. It requires at least two visits and, in most cases, some shaping of the tooth surface.

Composite veneers

Composite veneers are built up directly on the tooth with tooth-coloured resin, the same family of material used for white fillings. They can often be completed in a single visit with little or no removal of enamel, and they are easier to repair. On the other hand, composite can pick up stains and lose its shine over time, so it usually needs more maintenance. Composite work on one or two teeth is closely related; see our guide to composite bonding as a quick, conservative smile fix.

These figures are general averages, not promises: your habits, your bite and your oral hygiene matter as much as the material. For a detailed side-by-side comparison, read E.max veneers or composite veneers: which suits you?

You may also hear about “no-prep” or “minimal-prep” veneers. These are very thin veneers placed with little or no shaping of the tooth. They can work well in selected cases, such as small teeth or small gaps, but not every smile is suitable for them.

The procedure step by step

Ceramic veneers are usually completed over two to three appointments spread across about two to three weeks. A typical sequence looks like this:

1. Consultation and examination (about 30 to 60 minutes). The dentist checks your teeth, gums, bite and any old fillings, listens to what you would like to change, and may take photographs and X-rays. Any decay or gum disease is treated first.
2. Planning and preview. Impressions (moulds) of your teeth are taken so that the new shape can be planned. In many cases a trial version, called a mock-up, can be placed temporarily over your teeth so you can judge the proposed shape before anything is changed.
3. Tooth preparation (roughly one to two hours, depending on the number of teeth). A thin layer of enamel, often less than a millimetre, is shaped so that the veneer can sit naturally without looking bulky. Whether your teeth need shaping at all, and how much, is explained in do veneers require filing down your teeth? Temporary veneers are often placed to protect the teeth.
4. Laboratory stage (usually one to two weeks). A dental technician makes the veneers to the agreed shape and shade.
5. Fitting (often one to two hours). The dentist tries the veneers in, checks the colour and fit with you, then bonds them to the teeth with a resin cement hardened by a special light. Excess cement is removed and the bite is checked.
6. Review. A short follow-up visit a week or two later allows the dentist to check the gums and the bite and make small adjustments.

Composite veneers follow a shorter path. After planning, the dentist builds up the resin in layers directly on the teeth, then shapes and polishes it, usually in one longer appointment.

Does it hurt? Anaesthesia and what you feel

For most people, veneers are a comfortable treatment. When enamel is shaped, local anaesthesia (a numbing injection in the gum) is normally used, so you feel pressure and vibration but not pain. Composite veneers that need little or no preparation can sometimes be done without any anaesthetic.

After preparation or fitting, it is common to have mild sensitivity to cold for a few days, and the gums around the veneers may feel a little tender. Simple painkillers such as paracetamol are usually enough. Your bite may also feel slightly different at first; if a tooth feels “high” when you close, tell the dentist, because this is easy to adjust.

If you are nervous, say so at the start. Short breaks, an agreed signal to stop and a clear explanation of each step help many anxious patients feel in control.

Aftercare and how long veneers last

Veneers are not damaged by normal eating, but a few habits make a real difference to how long they last:

• Brush twice a day with a fluoride toothpaste and clean between your teeth every day. The edge where the veneer meets the tooth must stay clean to prevent decay and gum inflammation.
• Avoid biting very hard objects: ice, nut shells, pens, fingernails, or opening packets with your teeth.
• If you grind or clench your teeth, especially at night, ask about a night guard, a thin removable plastic splint that protects the veneers while you sleep.
• Wear a sports mouthguard for contact sports.
• With composite veneers, limit tea, coffee and smoking where possible, and have them polished at your check-ups.
• Keep regular dental check-ups and professional cleaning (scaling and polishing).

With this care, ceramic veneers commonly last ten to fifteen years and often longer, while composite veneers usually need polishing, repair or replacement after about five to seven years. Sooner or later every veneer needs to be replaced, so it is wise to see veneers as a long-term commitment rather than a one-off treatment.

One point is easy to overlook: whitening gel does not change the colour of veneers. If you would like your natural teeth to be whiter, this is usually done before the veneers are made, so that the shade can be matched.

Risks, limits and alternatives

Veneers are generally safe, but they have real limits, and it is better to know them in advance:

• Irreversibility: once enamel has been removed, the tooth will always need a veneer or another covering.
• Sensitivity: usually mild and temporary.
• Chipping or debonding: a veneer can chip, crack or come off, especially with grinding or a knock. It can often be re-bonded or replaced.
• Colour differences over time: natural teeth next to veneers may slowly darken while the veneers do not.
• Gum problems and decay: these can develop at the edges of veneers if cleaning is poor.

Veneers may not be suitable if you have untreated gum disease, heavy grinding that is not controlled, very little healthy enamel or a significant bite problem. In these situations other treatment usually comes first.

Alternatives worth discussing

• Teeth whitening, when the only concern is colour; it is often the first step.
• Composite bonding, for small chips or gaps on one or two teeth.
• Orthodontic treatment (braces or clear aligners), provided by orthodontists, to move crooked teeth into place instead of masking them.
• Crowns, when a tooth is heavily filled, broken or weakened after root canal treatment.

What to ask before you commit

A good veneer treatment starts with a frank conversation. These questions help you decide calmly:

1. Are veneers the right option for my teeth, or could whitening, bonding, orthodontics or crowns achieve a similar result with less change to the tooth?
2. Which material do you recommend for me, and why?
3. How much enamel will be removed, if any, and is the change reversible?
4. Can I see a preview (mock-up) of the new shape before my teeth are prepared?
5. How many teeth need veneers for a natural, balanced result?
6. How will the colour be chosen, and should I whiten my other teeth first?
7. What happens if a veneer chips or comes off, and what maintenance will I need?
8. Do I grind my teeth, and will I need a night guard?

What determines the cost

The cost of veneers is set individually after an examination. The main factors are:

• the number of teeth to be treated;
• the material chosen (ceramic such as E.max, or composite);
• laboratory work, and any mock-up or preview;
• treatment needed beforehand, such as fillings, scaling, gum care or whitening;
• the complexity of the case, including bite problems or old restorations to replace;
• extras such as a night guard.

Because these factors vary so much from one person to another, a reliable estimate is only possible after a consultation.
