Porcelain or Composite?
Porcelain and composite can both give a natural, attractive result, but they get there in very different ways and age differently. This guide explains the real trade-offs, and why we design your smile before choosing the material.
Porcelain or Composite Veneers: Which Is Better?
Neither is better for everyone. Porcelain veneers (from £800 per tooth at Comely Bank Dental in Edinburgh) are made in a laboratory, resist staining and commonly last 10 to 15 years or more, but usually need some enamel removed. Composite veneers (£300 per tooth) are built directly on the tooth in one visit, often with no drilling, and are easy to repair, but stain and wear sooner.
Which Is Better: Porcelain or Composite Veneers?
It depends on your teeth and what you want from the result. As a starting point:
- Porcelain veneers are thin ceramic shells made in a dental laboratory and bonded to the front of your teeth. They hold their colour and gloss for many years and commonly last 10 to 15 years or more, but most need some enamel removed to fit.
- Composite veneers are tooth-coloured resin sculpted directly onto your teeth in the chair. They can usually be placed with little or no drilling and are simple to repair, but they stain, dull and chip more readily, commonly lasting four to eight years before major refurbishment.
Porcelain usually suits bigger changes and people who want a long-lasting, low-maintenance result. Composite usually suits smaller changes and people who want to keep their enamel untouched. Many people fall in between, and that is where careful planning makes the decision.
How Is Each Type Made and Fitted?
Composite veneers are made directly on your teeth, usually in one appointment per arch. The tooth surface is cleaned and lightly prepared to help the bond, then composite is applied in layers of different shades and translucencies, shaped by hand, set with a curing light and polished. You leave with the finished result. A short review visit a couple of weeks later lets us refine the shape and polish.
Porcelain veneers take two main appointments, a few weeks apart:
- Preparation. The teeth are prepared as planned and scanned digitally with our iTero scanner. Temporary veneers protect the teeth and give you a feel for the new shape.
- Fitting. The laboratory-made veneers are tried in so you can check shape and shade before they are bonded permanently.
The laboratory stage is what gives porcelain its depth and lifelike surface, and it is also why it takes longer and costs more. Our page on porcelain veneers explains the visits in more detail.

Book a consultation to talk through porcelain and composite for your teeth. We'll explain what each would involve and give you a written plan with every fee.
How Much of Your Tooth Has to Be Removed?
This is the biggest difference between the two, and the one I'd encourage you to think about most.
Composite is usually additive. In many cases no enamel is removed at all; the material is simply built onto the tooth. That makes it largely reversible and keeps your options open.
Porcelain usually needs some enamel removed, typically a fraction of a millimetre, so the veneer sits within the natural outline of the tooth rather than looking bulky. With careful planning, preparation can often be kept minimal and within enamel, which gives the strongest bond. But enamel doesn't grow back. Once teeth are prepared for porcelain, they will always need a veneer or similar restoration.
How much is removed depends heavily on where your teeth are now. Teeth that sit forward or are rotated need more reduction to bring them into line, which is why straightening first with Invisalign is often the more conservative route. The free Invisalign consultation is a good place to explore that.
How Do They Compare in Appearance and Staining?
Both can look natural in skilled hands, but they behave differently.
Porcelain has a translucency and surface lustre very close to natural enamel. Its glazed surface is highly resistant to staining, so coffee, tea and red wine have little effect on it, and its colour stays stable for many years.
Composite can also be layered to look very natural, particularly for smaller changes. Over time, though, it gradually loses its polish and picks up stain, especially at the margins. Regular polishing at hygiene visits restores much of the shine.
| Feature | Porcelain veneers | Composite veneers |
|---|---|---|
| Made | In a dental laboratory | Directly in the chair |
| Appointments | Two main visits, weeks apart | Usually one per arch, plus a review |
| Enamel removed | Usually some | Usually little or none |
| Stain resistance | Excellent | Moderate; needs polishing |
| Typical lifespan | 10 to 15 years or more | 4 to 8 years |
| If chipped | Usually replaced | Usually repaired in one visit |
| Guide price | From £800 per tooth | £300 per tooth |
Lifespans are typical ranges, not promises. Results vary with your bite, habits and maintenance.
What Happens If a Veneer Chips or Needs Repairing?
Composite is very forgiving. A chip can usually be repaired by bonding new composite onto the existing material, often in a single short appointment, and a tired surface can be refreshed with a new outer layer. That makes composite easy to maintain, although it needs maintaining more often.
Porcelain is strong once bonded, but if it chips, a durable repair is harder. Small chips can sometimes be smoothed or patched with composite as a stopgap, but a significant chip or fracture usually means making a new veneer. Porcelain veneers can also occasionally debond, and a clean, undamaged veneer can often be re-bonded.
Whichever you choose, grinding is the main threat. If you grind or clench, we'll recommend a night guard to wear while you sleep, and we will look at your bite as part of planning.
What Do Porcelain and Composite Veneers Cost?
At Comely Bank Dental, porcelain veneers are from £800 per tooth and composite veneers are £300 per tooth. Most people considering veneers have somewhere between four and ten upper teeth treated, depending on how many show when they smile.
The headline difference is significant, but it isn't the whole story:
- Composite costs less at the start but usually needs regular polishing, occasional repairs and earlier replacement.
- Porcelain costs more at the start but needs less upkeep and generally lasts longer.
For larger cases, smile design (£250) and a trial smile (£250) are charged separately, and whitening may be part of the plan if you'd like your other teeth lighter.
Every fee is a guide price and is confirmed in a written treatment plan before anything starts. Members of our dental plan save 10% on most private treatment.
Who Suits Porcelain, and Who Suits Composite?
Porcelain is often the better fit if you:
- Have heavy staining or discolouration that whitening won't shift
- Have several large or discoloured fillings on your front teeth
- Want a significant change in shape, length or proportion
- Have had composite before that kept chipping or staining
- Prefer a long-lasting result with less day-to-day maintenance
Composite is often the better fit if you:
- Want a smaller change: chips, slightly short or uneven edges, small gaps
- Would prefer to keep your enamel intact
- Are younger and want to keep future options open
- Are happy to have your veneers polished and occasionally repaired
Neither may be right yet if you have untreated decay or gum disease, heavy grinding that isn't controlled, or very crowded teeth where straightening would be kinder. In some cases a crown better protects a heavily filled tooth.
Why Do Smile Design and a Trial Smile Come First?
Choosing between porcelain and composite is easier once you know exactly what you want your teeth to look like. That's what smile design is for, and porcelain veneers and smile design are areas I have a special interest in.
Smile design (£250) starts with photographs, video and digital scans of your teeth. We study how your teeth relate to your lips, face and gum line, then plan the shape, length and proportion of each tooth. It is also where we decide how many teeth need treatment, and whether straightening or whitening should come first.
A trial smile (£250) lets you see that design in your own mouth. A temporary tooth-coloured material is placed over your teeth, following the plan, without any preparation. You can look at it, photograph it, show people and talk through changes before anything permanent is done.
At Comely Bank Dental, these are charged separately from the veneers themselves. Their value is in the decisions they make clear: whether composite can achieve what you want, whether porcelain is needed, and how little tooth preparation the result requires. Our smile makeover page explains how larger plans fit together.
