Veneers and crowns can both change the shape, colour and size of your teeth, and once they are in place a well-made veneer and a well-made crown can look very similar. The real difference is how much of the tooth they cover, and that depends on what the tooth underneath actually needs. A healthy tooth that simply doesn't look the way you would like is a very different starting point from a tooth that has been weakened by decay, large fillings or a fracture. In this guide we explain what each option is, how they compare, how dentists usually decide between them and what you can expect from treatment and aftercare, so that you can go into your consultation feeling informed and calm.
What a veneer is
A veneer is a thin shell, usually porcelain such as E-max, bonded to the front of a tooth. Only a small amount of enamel is shaped, so most of the natural tooth stays in place. You can think of it as a new front surface: it changes what people see when you smile and talk, while the back of the tooth and much of its structure are left as they are. Because a veneer is bonded, in other words firmly glued, to the enamel, it relies on the tooth beneath it being strong and healthy.
Porcelain veneers
Porcelain veneers, including E-max, are made in a dental laboratory from an impression or a digital scan of your teeth. Porcelain reflects light in a way that is quite similar to natural enamel, which is why it can look very lifelike, and it resists stains from coffee, tea and red wine well. Porcelain veneers usually involve at least two appointments, with time in between for the laboratory work, and they are generally the more durable of the two main veneer types.
Composite veneers
Composite veneers are made from tooth-coloured resin, the same family of material that is used for white fillings. The dentist often builds them up directly on the tooth in layers, then shapes and polishes them by hand, sometimes in a single visit. Composite usually needs little or no shaping of the tooth and can be repaired or adjusted fairly easily. On the other hand, it is softer than porcelain, can pick up stains over time and often needs polishing or touch-ups sooner. Some people choose composite as a more conservative first step, or as a way to try out a new tooth shape before deciding on anything more permanent.
How much of the tooth is shaped
For porcelain veneers, the dentist usually removes a thin layer of enamel from the front of the tooth, often only a fraction of a millimetre, so that the veneer can sit flush and doesn't look bulky. In some cases very little or no preparation is needed, for example when teeth are small or sit slightly further back than their neighbours. Even when the amount is small, enamel does not grow back, so preparing a tooth for a porcelain veneer is generally considered a permanent decision. It is worth asking your dentist exactly how much they plan to shape on each tooth and why.
When veneers are a good fit
- Healthy front teeth with stains or discolouration that whitening cannot fully improve
- Small chips, worn edges or teeth that look too short
- Small gaps between the front teeth
- Teeth that are slightly uneven in shape or size
- Mild crowding or slightly turned teeth, when orthodontic treatment is not wanted or not needed
When veneers may not be the best choice
- Teeth with large fillings, deep decay or cracks that weaken the tooth
- Too little healthy enamel left for the veneer to bond to
- Heavy grinding or clenching that is not under control
- Gum disease that has not yet been treated
- Marked crowding or bite problems that orthodontics would correct better
What a crown is
A crown covers the whole tooth, like a cap. It is used when a tooth is weakened by a large filling, a fracture or root canal treatment and needs protection from all sides. Zirconia is a common choice because it is strong and looks natural. Because a crown wraps around the tooth, it holds it together and spreads biting forces more evenly, which helps protect what is left of the natural tooth from splitting.
To make room for a crown, the tooth is shaped on all sides, so more tooth structure is removed than for a veneer. On a healthy tooth that would be a real drawback. But when a tooth is already heavily filled or broken, a crown is often the most reliable way to keep it working for longer and to avoid losing it altogether.
Common crown materials
- Zirconia: very strong and well suited to back teeth that take heavy chewing forces; more translucent types of zirconia can also look natural on front teeth
- E-max (lithium disilicate): a glass-ceramic with very good translucency, often chosen for front teeth where appearance matters most
- Porcelain fused to metal: a metal base covered with porcelain, used for many decades and still an option in some situations, although a dark line can sometimes show at the gum if the gum recedes
When a crown is usually needed
- A large filling that leaves thin, fragile tooth walls
- A cracked or broken tooth
- A back tooth after root canal treatment, which can become more brittle over time
- Severe wear, for example from grinding or acid erosion
- A dental implant, which needs a crown to replace the visible part of the tooth
- A bridge, where crowns on neighbouring teeth support a replacement tooth in between
On an implant, the crown is attached through a connecting part called an abutment, either with a small screw or with cement. It looks like a natural tooth, but it sits on the implant rather than on a natural root, and your dentist will show you how to clean around it.
Veneers and crowns side by side
Both treatments can give a natural-looking result when they are carefully planned and well made. The main differences lie in how much of the tooth is involved and what each one is designed to do.
Tooth preparation
A veneer usually involves shaping only the front surface of the tooth, and sometimes the biting edge. A crown involves shaping the whole tooth, all the way around. If your tooth is healthy, a veneer is usually the more conservative option.
Strength and protection
A veneer improves how a tooth looks but adds little strength; it depends on the tooth beneath it. A crown protects the tooth from all sides, which is why it is chosen for teeth that are already weakened.
Appearance
Modern porcelain veneers and all-ceramic crowns can both look very natural. Veneers are typically used on the teeth that show when you smile. Crowns can be made for any tooth, from the front to the very back, and the material is chosen to balance strength and appearance for that position in your mouth.
Lifespan
With good care, porcelain veneers and crowns often last many years, but no restoration lasts forever. How long they last depends on your oral hygiene, your bite, whether you grind your teeth, your diet and how regularly you have check-ups. Composite veneers usually need more maintenance and tend to be refreshed or replaced sooner. Your dentist can give you a realistic idea based on your own situation.
Daily care
Neither needs special products. You brush and clean between them just as you would with natural teeth. The edges where the restoration meets the tooth deserve particular attention, because the tooth underneath can still develop decay there.
How dentists decide
The decision starts with an examination and X-rays. Your dentist looks at how much healthy tooth is left, how your teeth meet when you bite and whether you grind your teeth. The aim is to choose the option that solves the actual problem while keeping as much of your natural tooth as is sensible. These are some of the things your dentist will usually consider:
- How much healthy tooth remains: X-rays and a close examination show old fillings, decay, cracks and the condition of the roots
- Previous root canal treatment: a root-filled back tooth is often protected with a crown
- Your bite: the way your upper and lower teeth meet affects the forces on each tooth and on the edges of a veneer
- Grinding or clenching (bruxism): signs such as worn or flattened teeth may lead your dentist to suggest a stronger material and a night guard
- Gum health: gums should be healthy and stable before veneers or crowns are fitted, so gum treatment sometimes comes first
- The colour of your other teeth: porcelain does not respond to whitening, so if you would like whiter teeth overall, whitening is usually done before the shade is chosen
- Your own goals: what bothers you about your smile and how much change you would like
Sometimes the honest answer is neither. Whitening, composite bonding, orthodontic treatment or a simple filling may solve the problem with less work on your teeth. A good consultation should cover these alternatives too, so that you can make a choice you feel comfortable with.
Combining veneers and crowns in a smile makeover
Many smile makeovers combine both: veneers on healthy front teeth and crowns where teeth need more support. For example, someone might have veneers on several upper front teeth and a crown on one front tooth that had root canal treatment years ago and has darkened since. Treating every tooth the same way would mean either over-treating the healthy teeth or under-protecting the weak one.
When the two are combined, the dentist and the dental laboratory plan them together so that shade, translucency and shape match across the whole smile. Veneers and crowns made from compatible ceramics can be matched closely, even though one covers only the front of a tooth and the other the entire tooth. A careful plan also takes into account your lips, your face and your gum line, not just individual teeth, because a smile is seen as a whole.
What treatment usually looks like
Every clinic and every case is a little different, but the steps are broadly similar. Your dentist will explain your own treatment plan and how many visits it is likely to involve.
Veneers, step by step
- Consultation, examination, X-rays and photos of your smile
- Planning the new shape and colour, often with a mock-up or digital preview that you can see before anything is changed
- Any whitening or gum treatment that is needed beforehand
- Preparing the teeth, usually under local anaesthetic
- Taking an impression or digital scan for the laboratory
- Wearing temporary veneers while the final ones are being made, if needed
- A try-in to check fit, shape and shade, followed by bonding the veneers in place
- Checking and fine-tuning the bite, then a review visit
Crowns, step by step
- Examination and X-rays to check the tooth and its root
- Treating any decay, plus root canal treatment if it is needed
- Rebuilding the core of the tooth if a large part of it is missing
- Shaping the tooth all the way around, usually under local anaesthetic
- Taking an impression or digital scan
- Wearing a temporary crown while the final one is being made
- Fitting and cementing or bonding the final crown, then checking the bite
If you are travelling for treatment, ask how many days the plan requires, whether any steps can be prepared before you arrive and what follow-up is recommended once you are back home. Some sensitivity to hot and cold is common for a short while after the teeth have been prepared, and it usually settles on its own. Let your dentist know if it doesn't.
Caring for veneers and crowns
Veneers and crowns are looked after much like natural teeth, but a few habits make a real difference to how long they last.
- Brush twice a day with a soft toothbrush and fluoride toothpaste
- Clean between your teeth every day with floss or interdental brushes, paying attention to the edges near the gum
- Avoid biting on very hard things such as ice, nut shells, pens or fingernails
- Don't use your teeth as tools to open packets or bottles
- Wear a night guard if your dentist recommends one
- Use a sports mouthguard for contact sports
- Keep up regular check-ups and professional cleanings
- With composite veneers, cut down on strongly staining food and drinks and ask about polishing from time to time
If something feels different, such as a rough edge, a change in your bite or a small chip, contact your dentist early. Small problems are usually much easier to fix when they are caught early.
Common myths and misconceptions
There is a lot of confusing information about veneers and crowns online. Here are some of the ideas patients most often ask about.
- “Veneers ruin your teeth.” Porcelain veneers do involve removing a thin layer of enamel, and that is permanent, but on suitable teeth the amount is usually small. What matters is that the treatment is genuinely needed and carefully planned.
- “Crowns always look fake.” Older crowns with visible metal edges gave crowns that reputation. Modern all-ceramic crowns can blend in very naturally with your other teeth.
- “Teeth under veneers and crowns can't decay.” They can, especially at the edges. Good daily cleaning and regular check-ups still matter.
- “You can always whiten them later.” Porcelain and zirconia don't change colour with whitening, which is why whitening is usually done before treatment.
- “Veneers can fix any crooked smile.” They can disguise mild irregularities, but larger alignment or bite problems are often better treated with orthodontics.
- “One option is simply better.” Neither is better in general. The right choice depends on the condition of each individual tooth.
Questions to ask at your consultation
- Which teeth would get veneers, and which would need crowns?
- Why do you recommend this for each tooth, and are there more conservative alternatives?
- How much of each tooth will be shaped?
- Which material do you suggest, and why?
- Can I see the planned result before treatment starts?
- Should I whiten my teeth first?
- Do I show signs of grinding, and will I need a night guard?
- How many visits are needed, and how much time is needed between them?
- What should I do if a veneer or crown chips or comes loose?
- How should I care for them afterwards, and how often should I have check-ups?
