Crown or Veneer?

When a veneer may be suitable

• Most of the tooth is sound, and the concern is only colour or shape.
• There is enough enamel on the front surface and the gums are healthy.
• Small cracks, worn edges, slight differences in shape and length, small gaps.
• Mild to moderate discolouration that has not responded to whitening; on very dark teeth, a thin veneer may not mask the colour well enough.

When a crown may be suitable

• Tooth structure reduced by a large filling.
• A fracture or crack running below the gum or towards the root, once its extent and whether the tooth can be restored have been assessed.
• A back tooth that has had root canal treatment and has been weakened.
• A tooth that will support a bridge.

When more conservative options are considered first

• The tooth is healthy and the concern is only its appearance. Having nothing done is also an option.
• The concern is only colour. Depending on the cause of the discolouration, whitening first, if suitable.
• A small flaw in shape, or a small chip on one tooth. Bonding is often enough.
• Crowded teeth. "Straightening" them with veneers or crowns means removing a great deal of tooth tissue; orthodontics is assessed first.
• Active decay or gum disease. This is treated first.
• Teeth that are still developing. Veneers and crowns are usually postponed in young patients.

In-between situations

Root canal treatment or a large filling does not on its own call for a crown: if enough sound tissue remains, a filling or an onlay, which partly covers the chewing surface of the tooth, may be enough. Discolouration of a front tooth after root canal treatment can be dealt with by whitening from inside the tooth or with a veneer, if the tooth itself is sound. Whitening from inside the tooth has, in rare cases, been linked to damage on the outer surface of the root¹ (external cervical resorption); ask about this risk before it is done. The decision is made at an examination, based on the tooth tissue that remains, your bite and your habits.

Enamel and dentine

Enamel is the hard outer layer of the tooth, and it does not grow back. With a veneer, the preparation often stays within the enamel; with a crown, the tooth is reduced on every surface, so much of the enamel goes and the dentine is exposed. The difference is not only the amount of tissue: ceramic bonds more reliably to enamel than to dentine. In one retrospective study that followed 580 veneers for up to 12 years, veneers bonded to dentine were about 10 times more likely to fail². The more the tooth is cut, the less enamel remains.

The nerve of the tooth

In the pooled results of 37 studies covering teeth that were vital at the start and were treated with indirect restorations (crowns, partial restorations and bridge supports), the nerve lost its vitality in about 5 of every 100 teeth³; in studies with more than ten years of follow-up, the figure was about 7. The certainty of the evidence is low. If this happens, root canal treatment is needed to keep the tooth; it sometimes appears years after the crown was made. Preparation is not the only cause: earlier decay, fillings and the other stages of treatment also contribute. The more teeth are prepared for crowns, the more likely you are to face this risk.

The gums and opposing teeth

If the edge of a crown does not fit the tooth well at the gum line, or plaque collects there, gum inflammation and recession can occur; receding gums make the edge of the crown visible. Ceramic surfaces can wear the opposing teeth⁴; the surface finish (polished or glazed) and adjusting the bite may affect this, but the evidence is limited.

The risks of veneers themselves

Fracture and coming off are the main reasons veneers fail. Clenching or grinding increases this risk; for some patients, a veneer may not be suitable for this reason. A night guard may be recommended; limited observational data⁵ suggest it may reduce the risk of fracture, but the protection is not certain.

Daily care

Neither a crown nor a veneer protects the tooth from decay; new decay can develop at the edge or underneath. Brushing twice a day with a fluoride toothpaste, cleaning between the teeth every day, not biting hard objects with the front teeth, and check-ups at intervals set for you apply to both restorations.

The figures below come from different groups of patients and different follow-up periods; they are not enough to compare the lifespan of veneers and crowns directly. Restorations still in the mouth may have needed repair.

• Veneers. According to the pooled results of studies on glass-ceramic veneers (feldspathic, leucite-reinforced and lithium disilicate), about 94-97%⁶ of veneers are still in place after 10 years; the same analysis has no long-term data for zirconia veneers. Another review, covering 25 studies and 6,500 veneers, found about 95%⁷ at ten years.
• Crowns. In a 2026 review, across four material groups of single crowns on natural teeth (monolithic lithium disilicate, porcelain-veneered zirconia, porcelain fused to metal, monolithic zirconia), about 97 to 99 of every 100 crowns⁸ are still in the mouth after five years. For porcelain fused to a high-gold alloy, the estimate for 2,211 crowns placed in a single practice, a group selected because they were in good condition at the time of cementation, is that about 85 of every 100 remain in the mouth after 25 years⁹.

The outcome depends on the condition of the tooth, how much tissue can be preserved, the bite, care, the material and the design of the restoration, all together. Choosing a crown for a sound tooth because it is more "durable" ignores the tissue it removes and the risk to the nerve.

Read the plan you have been given with these questions:

1. What is suggested for which tooth, and why? Ask for a reason for each tooth. A single-line plan such as "crowns on 20 teeth" should be explained if it includes sound teeth.
2. Why is a veneer, bonding or whitening not enough for this tooth? The answer should rest on the condition of the tooth, not on a material name or a package.
3. How much tissue will be removed from each tooth? This cannot be said without an examination, with X-rays where needed; plans made from photographs alone are a preliminary assessment.
4. Is root canal treatment a possibility? The condition of the nerve is assessed beforehand in teeth planned for crowns; for some teeth, root canal treatment is part of the plan from the start.
5. Is there a trial stage? A trial in the mouth with a temporary material lets you see the shape and the bite before the permanent work.
6. How many appointments, and how far apart? The number of appointments and the need for temporary restorations depend on the production method; trial, fitting and check-up appointments are part of the plan.
7. What happens afterwards? Ask in advance who will deal with a fracture, a restoration coming off or sensitivity, and how, and ask for the terms in writing.

If you are undecided between two plans, getting a second opinion is normal. Ask for your X-rays and photographs; they are useful for a second opinion, or to show another dentist in future.

The steps are similar for both; the difference is in how much preparation is done. There is more detail on the veneer page and, by material, on the e.max, zirconia and porcelain-fused-to-metal crown pages.

If you have a crown or veneer, contact your dentist if any of the following happens:

• Sensitivity that lasts more than a week or keeps getting worse; pain that starts with heat and lingers
• Pain when biting, or a feeling that the tooth is high when you bite together
• A fracture, crack or looseness in the crown or veneer
• Bleeding, recession or a dark line in the gum at the edge of the crown or veneer
• The crown or veneer coming off: keep the piece, and do not glue it back yourself

Emergencies. Throbbing pain, facial swelling or a fever are not expected; see a dentist without waiting. If you have difficulty breathing or swallowing, swelling of the mouth and neck that is spreading quickly, or swelling around the eye, go to an emergency department or call 112.

Fees are not given on this page. The main factors that shape the plan are: the type of treatment (veneer or crown), how many teeth are treated, the material and production method, treatment needed first (decay, gums, root canal treatment), temporary restorations and check-up appointments. The fewer teeth are treated, the lower both the cost and the amount of tissue removed from the teeth. Ask for the plan in writing, showing which treatment is suggested for which tooth and why.
