How long do veneers last? Porcelain and composite

Veneers are one of the most-asked-about cosmetic treatments, and the question people ask next is almost always: how long do they actually last? The honest answer depends on the material, how well you look after them, and a few habits that most people do not realise matter. Here is what to expect from porcelain and composite veneers, and what makes the difference.

Porcelain veneers: 10 to 20 years

Porcelain is a hard, glass-like ceramic that resists staining and wears well. Most studies put the survival rate for porcelain veneers at around 90 per cent or higher at 10 years, and many last 15 to 20 years without any significant problems. The material is colour-stable, so they do not yellow the way natural teeth do, and they feel and look very close to real enamel. If you are considering the full picture of your options, our comparison of veneers, bonding and whitening is a useful starting point.

Composite veneers: 5 to 7 years

Composite resin veneers are made from the same tooth-coloured material used for fillings. They are less expensive, can usually be placed in one visit, and require less removal of tooth enamel. The trade-off is durability: composite is softer than porcelain and more prone to chipping, and it can pick up staining from tea, coffee and red wine over time. That said, small chips and stains can often be polished or repaired rather than replaced in full, which keeps ongoing costs manageable.

What shortens a veneer's life

• Teeth grinding (bruxism) — the most common reason veneers fail early; a night guard is essential if you grind
• Biting nails, pens, ice or very hard foods, which can chip the edge
• Using your teeth to open packaging, which most people forget they do
• Abrasive toothpastes, which dull the surface over time
• Skipping check-ups, so small margin gaps go unnoticed until decay starts underneath

Grinding in particular is something dentists see cause veneer failure regularly. If you have any sign of grinding, such as waking with a sore jaw or seeing wear on other teeth, ask about a custom night guard before or at the same time as getting veneers. Our post on teeth grinding and night guards explains the options.

When does a veneer need replacing?

A veneer typically needs attention when it chips or cracks, when the margin at the gum lifts (allowing bacteria in), when the gum has receded enough to show the edge, or when the colour is visibly different from the surrounding teeth. Catching these early at a routine check-up often means a repair or re-polishing rather than a complete replacement. The underlying tooth is still there, so as long as it is healthy, a new veneer can be fitted at any point.

How to make veneers last as long as possible

None of this is difficult. Use a soft toothbrush and a non-abrasive toothpaste, floss around the margins, wear a night guard if you grind, and see your dentist for a check-up every 6 to 12 months. Those four things account for most of the difference between a veneer that lasts 7 years and one that lasts 18.
