What is a Dental Crown?

Crowns (sometimes referred to as caps) are used to restore to heavily filled, broken or worn teeth, they can also be used to improve the appearance of teeth. They cover the entire tooth, strengthening and protecting the remaining tooth tissue.

What materials are used for the Crowns?


Gold has been used to restore teeth for a very long time. Today technicians use gold mixed with an alloy of metals to give it additional strength. Gold crowns are strong in thin section and therefore require minimal tooth preparation; however they are gold in appearance.

Porcelain bonded to precious metal

The majority of crowns are constructed in this way. A shell of precious metal alloy is layered with thin applications of tooth coloured porcelain. Traditionally this provided a strong crown which appears tooth-like in colour, however modern materials provide metal free crowns which are just as strong.

Ceramic crowns

At Kenilworth Dental Practice we use two forms of ceramic crowns, all-ceramic and ceramic pressed to zirconia. Ceramic crowns give the best aesthetic result as they appear most like tooth enamel. Modern ceramics are very strong; they are technique sensitive and require specific tooth preparation.

What will we do?

You will require at least two visits for the crown. At your first appointment the tooth will be shaped to create space for the crown and the correct retention (based on the material chosen), then impressions are taken. Your dentist will construct and fit a provisional crown to last whilst your restoration is being made. The impressions are sent to our technician, who then constructs your crown by hand. This process takes between 10 and 14 days.

At your second visit your dentist will remove the provisional crown and try in your restoration, once your dentist is happy with the fit of the crown they will check that you are happy with how it feels and looks before cementing or bonding the crown to the tooth. A series of final checks are made, and if required some minor adjustments.

If you having multiple crowns made there will be other stages involved. Your dentist will discuss this with you as part of your treatment planning.
