Porcelain or Composite?
Dr Nikhil Sharma sets the two materials side by side and explains the questions that usually settle the choice.
Is Porcelain or Composite Better for Veneers, and What's the Price Difference in Hamilton?
Porcelain is the longer-lasting and more stain-proof choice, often 10 to 15 years, but it usually means shaping away a fine layer of enamel for good. Composite is sculpted onto the tooth in one or two visits with little or no drilling, costs less up front, and tends to need polishing or refreshing within three to five years. In Hamilton, porcelain veneers are from £695 a tooth and composite veneers £395 a tooth.
The Short Version
Both materials cover the front of a tooth to change its colour, shape or length. Both can close small gaps and disguise slightly uneven teeth. From across a room, a well-made composite veneer and a well-made porcelain one can look much the same.
The differences show up over time and inside the tooth. Porcelain is made in a laboratory, keeps its shine and colour for many years, and usually needs some enamel removed. Composite is built by hand in the chair, keeps more of your natural tooth and costs less now, but wears and picks up stain sooner. Most decisions come down to how long you want the result to last and how much tooth you're willing to change to get it.
Side by Side
| Feature | Composite | Porcelain |
|---|---|---|
| How it's made | Sculpted onto the tooth by hand | Made by a dental laboratory from a 3D scan |
| Enamel removed | Little or none | Usually a fine layer, permanently |
| Appointments | One or two | About three, over three to four weeks |
| Look | Natural when fresh; can dull | Glass-like, closest to enamel |
| Staining | Picks up tea, coffee and wine over time | Very resistant |
| Usual lifespan | Three to five years before a refresh | 10 to 15 years, often longer |
| A chip | Usually patched in one visit | Usually means a new veneer |
| Fee, a tooth | £395 | From £695 |

What Happens to Your Own Tooth
This is the question we'd put first. Composite usually bonds straight onto the enamel. Sometimes a sharp edge is smoothed or a little enamel is roughened to help the bond, and most people don't need an injection. In many cases, if you later decided against it, the composite could be polished off.
Porcelain needs room. To avoid a bulky look, around half a millimetre of enamel is commonly shaped from the front of the tooth under local anaesthetic. That can't be reversed, and those teeth will always need covering. Dr Sharma uses your approved design to keep the reduction as small as your case allows, and on some teeth that are already small or set back, very little is needed.
Lifespan, Repairs and Wear
Porcelain is hard and glazed, so it holds its colour and surface shine for a decade or more. The catch is that when it fails, it tends to fail completely: a crack or a large chip normally means a new veneer from a fresh scan.
Composite is softer. It loses some lustre over the years, can stain at the edges, and small chips are fairly common, especially on biting edges. The upside is that it can be repaired. A chip is usually smoothed and rebuilt in a short appointment, and a tired set can be polished and refreshed rather than started again. Composite needs more frequent attention but less drastic work each time.
Price Now, Price Later
Today, composite is the cheaper way to treat a tooth: £395 against from £695 for porcelain. 1 For several teeth, composite also comes in packages that include home whitening, from £1,550 for four teeth up to £3,950 for ten.
Over ten or fifteen years the sums move closer, because composite usually needs refreshing a few times in the period a set of porcelain veneers might last. If you want the same colour for a long time and you're happy with some enamel being removed, porcelain often works out as good value. If you'd rather spend less now and keep more of your teeth, composite usually makes more sense. Neither material is discounted on the dental plan.
Four Questions That Usually Decide It
- Are your teeth very dark or heavily filled? Porcelain masks deep discolouration and old fillings more reliably. Composite would have to be built thick to hide them.
- Are your teeth healthy and largely untouched? Composite lets you change their look while keeping almost all of the enamel.
- Do you grind or clench? Composite chips more easily but is easy to repair; porcelain is tougher but can crack under heavy force. A night guard (£210) protects either.
- Are your teeth crowded? Straighten first, usually with Invisalign. Either material can then be thinner, and some people find they no longer want veneers.
Many people start with composite, live with the new shape for a few years, then move to porcelain using what they've learned about what they like.
Seeing the Result Before You Commit
Whichever material you lean towards, your new smile is designed on photographs and a 3D scan of your own teeth, then shown to you as a trial smile placed over your teeth. No drilling or glue is involved, and it comes off before you leave. Changing the design at that point costs nothing.
The design and trial smile are part of your treatment fee. For porcelain, the approved design also guides how much each tooth is shaped. Our trial smile guide covers what to check while you're wearing it.
Caring for Either Type
- Brush twice a day with a low-abrasion toothpaste; whitening pastes can scuff composite
- Clean between the teeth every day, because gum problems at the edges shorten any veneer's life
- Keep hygiene visits, where composite gets polished and porcelain margins get checked
- Don't use your front teeth on pens, ice, nutshells or packaging
- Remember that neither material whitens, so lighten your natural teeth before veneers are matched
