Veneers and crowns: the difference
A porcelain veneer is a thin layer that covers only the front of the tooth and usually needs a small amount of surface reduction. A crown covers the tooth on all sides and is chosen to protect a tooth that has been seriously weakened.
Which material, where?
Glass ceramics (such as lithium disilicate, E-max) let light through much like natural teeth and are often used for veneers and crowns at the front, where aesthetic demands are high. Zirconia is a very strong material and stands out for back teeth, bridges and implant restorations. The choice depends on the position of the tooth, the remaining tooth structure and bite force.
Impressions can be taken with a digital scanner or with conventional impression materials. Computer-aided design and manufacturing (CAD-CAM) allows the pieces to be made with high precision.
How does the process work?
Examination and plan
Tooth and gum health are assessed, X-rays are taken if needed, and the right type of restoration is chosen.
Tooth preparation
A very thin preparation is made for veneers and a more noticeable one for crowns. This is done under local anaesthesia.
Impressions and temporaries
Impressions are taken; while the permanent pieces are being made, the teeth are protected with temporary crowns.
Try-in and bonding
Colour, shape and fit are checked in the mouth; after your approval the pieces are bonded permanently.
Review
Bite and gum fit are checked, and care advice is given.
Care
- Brushing twice a day, flossing and interdental brushes protect the edges of crowns and veneers.
- The tooth under a crown can decay, which is why regular check-ups matter.
- Avoid forcing them, for example opening bottles or cracking hard pits.
- If you clench, a night guard may be recommended.
Frequently asked questions
Zirconia or porcelain veneers?
These two options meet different needs. For changing the colour and shape of healthy front teeth, veneers are often enough. If a tooth has a large filling, a fracture or a root canal treatment, a full crown may be needed. The decision is made after the examination, based on the condition of the tooth.
Can a crowned tooth decay?
The crown itself cannot decay, but the tooth structure at its edges and underneath can. Good oral care and regular check-ups reduce this risk.
How long do crowns and veneers last?
Their lifespan depends on the material, the position of the tooth, bite force and care. With regular care and check-ups they can last for many years.
