Composite or Porcelain Veneers: How They Compare

How long each lasts: what the studies show

Each study below looked at a different group of patients over a different period, so their figures cannot be set side by side as if they came from one study.

• A two-year randomised trial. 28 selected patients with several gaps between their front teeth had 120 veneers, half composite and half lithium disilicate ceramic. Survival was about 93 in 100 for composite and 95 in 100 for ceramic, not a significant difference; composite edges discoloured more often². The trial counted fractures, including composite ones that were repaired, against survival. People who grind their teeth were excluded.
• Ten years in one practice. 1,459 veneers in 341 patients were followed for up to 10 years. Annual failure rates calculated over the ten years, counting repairs and replacements, were 10% for composite and 2.8% for ceramic; counting only replacements, 4.1% and 1.2%³. These summarise the whole period; they do not predict the risk in any single year. The study was not randomised, so the difference may not be due to the material alone.
• Pooled studies of each material. Pooling randomised trials of composite veneers, made on the tooth or in a laboratory, about 88 in 100 were still in place⁴; the studies' average follow-up ranged from about 2 to 8 years. For three kinds of glass-ceramic veneer, about 94 to 97 in 100 were still in place at about ten years, with no significant difference between them⁵. These come from different studies and periods.
• Composite made in a laboratory. In a ten-year split-mouth trial of 48 veneers, 75% of the lab-made composite veneers and all of the ceramic ones survived⁶. This applies to lab-made composite only, not to veneers built up on the tooth.

An older review found no reliable evidence that veneers made on the tooth or in a laboratory last longer than the other⁷; it was withdrawn in 2015 as out of date, so it is history rather than today's answer.

Put together: the longer studies lean towards ceramic, but equal lifespans have not been shown², nor has a longer life for porcelain in every patient³. How your own veneers do depends on the tooth, the bite, the enamel kept and your care; more on this in how long veneers last.

Stains, chips and repairs

Staining

Composite picks up stain from coffee, tea, red wine and smoking more easily. Porcelain is not immune at the edges: in the 2025 review of ceramic veneers, staining at the edge was reported in about 12 in 100 at around ten years⁵.

Chips and fractures

Porcelain can break too. Over about ten years, about 4 in 100 ceramic veneers cracked, 3 to 4 in 100 chipped, 2 to 3 in 100 fractured and about 2 in 100 came off⁵; the studies varied widely. The sources we use give no comparable long-term chipping rate for composite veneers built up on the tooth.

Repair

Composite is easier to fix if damaged¹. With either material, small chips may be repaired, and sometimes a new veneer is needed⁸. For fillings, studies comparing repair with replacement found no clear difference⁹, but there were only three and the certainty was very low; none looked at veneers.

Colour

The colour of a veneer cannot be changed after it is bonded¹⁰, whichever material it is. Your natural teeth may change colour over the years, so a difference can appear with both.

Sensitivity, decay and daily care

Teeth can become more sensitive because some enamel is removed¹⁰. Neither material protects the tooth from decay, which can start at the edge. Brush twice a day with fluoride toothpaste, clean between your teeth every day, avoid biting hard objects with your front teeth, and keep to your check-ups.

Questions that decide it for your teeth

1. How much do you want to change? Closing a small gap or rebuilding a chipped edge is a small change. Changing the colour and shape of several teeth at once is a bigger one, and worth planning tooth by tooth.
2. How much enamel is left? Both materials bond best to enamel. For porcelain, veneers bonded to dentine were about 10 times as likely to fail¹¹ in one retrospective study of 580 veneers.
3. Do you clench or grind your teeth, or have a deep bite? Veneers may not be suitable for some people who clench or grind¹⁰, with either material; a deep bite is also assessed¹. A night guard may be advised.
4. How do you feel about upkeep? Composite stains and wears more easily, so expect repairs or a replacement along the way. Porcelain resists stains and wear better, but it can also chip or come off.
5. Are the teeth and gums healthy? Decay and gum disease are treated first.

If the tooth is healthy and only the look bothers you, doing nothing is also an option. A small chip or gap may need only a small composite addition rather than a veneer. If the only concern is colour, whitening may be enough. If the teeth are crowded, orthodontic treatment is assessed first. The difference between a veneer and a crown is explained in crowns or veneers, and how a composite veneer is made in composite veneers.

When to see a dentist

Contact your dentist if any of these happens with a composite or a porcelain veneer.

• A chip, crack or rough edge
• A veneer comes off: keep it, and do not glue it back yourself
• Sensitivity that lasts more than a few weeks or gets worse
• Bleeding, swelling or a dark line at the gum edge
• Your bite feels high

Emergencies. Throbbing pain, facial swelling or a fever: see a dentist without waiting. Difficulty breathing or swallowing, or swelling in the mouth or neck that spreads quickly: go to an emergency department or call 112.
