Dental Crowns in City of London

Crowns are restorations that are designed to cover a tooth completely to protect it from fracture. This becomes necessary when a filling is very large and the remainder of the tooth is left very thin and at risk of fracture. Root filled teeth are commonly crowned as they are of a higher risk of fracture due to the large and deep fillings required after root canal therapy has finished. In some cases teeth can be crowned to alter the shape or position in order to make an aesthetic improvement.

Crowns can be constructed from a range of materials both porcelain and metal. Some materials will be more appropriate than others depending on the position in the mouth, visibility in your smile, level of impact from your bite and the amount of tooth remaining prior to crowning. If there an old filling in a tooth this would normally be replaced as part of the crowning procedure to ensure that the foundation for the crown is sound.

Crowns cost from £575 depending on the complexity and the material chosen. A crown requires two appointments to be completed. We will make you a temporary crown to wear between visits.

  • Inlay, Onlay and Crown FAQs

    Sometimes a tooth will have a large cavity or crack, but not enough damage to require a full dental crown. When it requires more strength than a filling would provide we recommend an inlay or onlay as the restoration of choice.


    What exactly are Inlays and Onlays?

    Inlays and onlays are reinforced fillings that can be made out of ceramic, gold or composite. They are generally strong enough to resist biting forces to preserve the health of the tooth.


    How do they differ?

    Inlay: Fits inside the tooth and just like a normal filling. They are constructed in the laboratory of a material that is stronger than normal filling material. The laboratory technician can also help design a contact that is tight against an adjacent tooth or teeth which in some cases is difficult to do in the mouth. The inlay is bonded into your tooth.

    Onlay: Covers part of the top of the tooth, such as the cusps or corners of the tooth as well as filling in the middle of the tooth. They are generally larger than an inlay. By covering a corner that is thin or weak with the onlay material it helps to protect that corner from fracture. With extensive damage or if we are replacing a very large filling we may recommend a crown instead of an onlay.


    What is the advantage of an inlay or onlay?

    You get the strength of a crown but an inlay/onlay is less invasive so is a more conservative procedure. These restorations are constructed in porcelain or composite and are tooth coloured. For worn teeth or in people who grind their teeth we may occasionally recommend gold.


    Crowns

    A crown provides full coverage of a tooth that is either very heavily filled or has been badly damaged. We would normally replace any old fillings on the tooth before crowning so we know that the foundation for the crown is sound. The filling under a crown is called a core filling. In the case of a root filled tooth a post may need to be placed to retain the core filling if there is not enough remaining tooth.

    Crowns are most commonly constructed in porcelain but in some cases we may recommend gold.

    Crowns are routinely recommended for root filled teeth as these teeth are very high risk to fracture and often require full coverage protection.

    Each case is different so be sure to visit us so that we can assess your situation and recommend the best solution for you.


    The procedure for Inlays, Onlays and Crowns

    The procedure is usually two appointments. Prior to starting we will need to assess the health of the root by taking a radiograph and review the condition of the remaining tooth. In the case of a root filled tooth we may need three appointments if we have to place a post and core filling.


    Appointment One

    Your tooth is anaesthetised. Any old filling material is removed and the tooth shaped to receive the new restoration. We take an impression of your tooth, as well as a bite registration and the shade. These records are sent to the laboratory to construct your new restoration. Your Dentist will make you a temporary restoration so your tooth is covered while the new restoration is made. It is bonded in place with a soft bond material that is easy for us to remove at your next appointment. After your first appointment you may or may not experience some minor hot and cold sensitivity. We also recommend that you do not eat chewy or hard foods on your plastic temporary restorations or floss around these. This is to minimise your risk of dislodging the temporary restoration.


    Appointment Two (normally 2 weeks later)

    The tooth will be anaesthetised again. The temporary restoration is removed and the new restoration tried in. The Dentist will check the fit and aesthetics of your new restoration.

    The restoration will then be bonded to your tooth.

    You may or may not experience some hot and cold sensitivity after placement. We would consider this normal for period of up to six weeks.
