Dental crowns have different properties depending on the material used. The right choice is made according to the position of the tooth, functional needs and aesthetic expectations.
Metal-free (all-ceramic) crowns
Metal-free crowns such as zirconia and E-max are often preferred for their natural appearance and biocompatibility. They may be considered for front and back teeth for different reasons.
Choice by area of use
Durability may be to the fore in back teeth, while translucency and aesthetics may matter more in front teeth. The choice is therefore individual.
How is the decision made?
Tooth structure, bite, gum health and expectations are assessed, and the suitable crown type is planned by the dentist.
Frequently asked questions
Which crown type is best?
There is no single “best” option for everyone; the suitable type is determined by the person’s situation.
Will the crown colour match my teeth?
Colour and shape are planned to match the natural teeth.
Is a bridge also a crown?
A bridge completes a missing tooth by supporting it with crowns on the neighbouring teeth; it may be considered where relevant.
Crown types by material
The differences between crown types are not only aesthetic; strength, translucency, gum compatibility and the amount of preparation required all vary. Metal-ceramic crowns have been used for many years. Among metal-free options, zirconia is noted for strength while glass ceramics offer a more natural appearance.

- Temporary crowns for the interim period
Front and back of the mouth
Appearance tends to be the priority at the front, while resistance to chewing forces matters more at the back. Different materials may therefore be chosen in different areas of the same mouth, with shade matched to the neighbouring teeth.
How the choice is made
The suitable crown type is recommended after assessing the position of the tooth, remaining structure, gum health, bite relationships and your expectations. The advantages and limitations of each option are explained at the examination.
Frequently asked questions
Is a more expensive material always better?
No. The most suitable material depends on the clinical situation rather than cost alone.
Can crowns be matched to existing teeth?
Shade is selected with the adjacent teeth as reference, and try-in stages allow adjustments before final cementation.
