Veneers or crowns: what is the difference?

Veneers and crowns are both used to improve the appearance of teeth, and they are often confused. The difference comes down to how much of the tooth they cover, and why.

Veneers cover the front

A veneer is a thin shell bonded to the front surface of a tooth. It changes what you see when you smile: colour, shape, length and small irregularities. Because it covers only the visible surface, it usually needs less preparation of the tooth than a crown.

Veneers are typically used on front teeth that are healthy but discoloured, worn, chipped, slightly uneven or spaced. More on the veneers page.

Crowns cover the whole tooth

A crown fits over the entire visible tooth like a cap. It restores shape and appearance, and it also holds a weakened tooth together. That makes crowns the usual choice when a tooth is broken, heavily filled, badly decayed or has had root canal treatment.

Crowns are used on front and back teeth, and they are also what sits on top of a dental implant. More on the crowns and restorations page.

When each makes sense

A healthy tooth with a cosmetic concern is often a candidate for a veneer, keeping more natural tooth.

A tooth that has lost a lot of structure usually needs a crown, because a thin veneer has too little to bond to and offers no protection.

A mix of both is common in a smile makeover, where some teeth need veneers and others crowns, all designed to match.

Materials

Both are most often made of ceramic, chosen for strength and the way it reflects light like natural enamel. Composite resin is sometimes used for veneers built directly on the tooth. The material is chosen for each tooth’s position and the forces it will face.

Things to think about

• Tooth preparation. Both involve reshaping the tooth to some degree, which cannot be undone. The amount depends on the case.
• Your bite and habits. Grinding, clenching and nail biting put restorations at risk. A night guard may be advised.
• Lifespan. Both are durable but not permanent, and may need replacing in time.
• Shade. Whitening, if wanted, is usually done before the shade of new restorations is chosen.

The right choice is individual

The best option depends on the condition of each tooth, your bite and what you would like to change. At a consultation, Dr. Nour examines the teeth and explains which approach suits each one, so the result is natural and lasting.
