Dental Crowns

What is a dental crown?

A crown (also sometimes known as a ‘cap’) is an artificial restoration that may be fitted over the remaining part of a broken, decayed or damaged tooth, restoring its function. It may also be fitted for purely cosmetic reasons to correct discoloured or misshapen teeth and achieve a bright white smile.

To fit a crown, much of the old tooth is removed, leaving a small peg onto which the crown is fixed. As it can take some time for the dental laboratory to custom make your new crown, it is likely that you won’t have the crown fitted on the same day.

Why might I need a dental crown?

  • You have broken teeth
  • Teeth have been weakened by decay or a very large filling
  • You have discoloured fillings and wish to improve the appearance of the tooth
  • You have had a root filling which needs a crown to protect the remainder of the tooth
  • To hold a bridge or denture firmly in place
  • Cosmetic dentistry reasons

How is a dental crown prepared?

Your dentist will remove most of the outer surface of the tooth, to the thickness of the crown, leaving a strong inner core. Once the tooth has been shaped, an impression (or mould) of the prepared tooth will be taken, as well as one of the opposite jaw and possibly a third to mark the way you bite. These impressions are then used by the dental technician to custom make your dental crown.

What is a post crown?

For patients with root-filled teeth it is sometimes necessary to insert a post in order to provide support and help the dental crown to stay in place. A post may be made of prefabricated stainless steel, which your dentist can fit directly into the root canal, or it may be custom-made by the dental technician to exactly fit the shape of the prepared root canal. Once the post is cemented into position, the crown can be securely attached.

Is there an alternative to post crowns for root-filled teeth?

In cases where a root-filled tooth has not completely broken down, it can sometimes be possible to build the tooth up again using special dental filling material. This ‘core’ can then prepared in the same way as a natural tooth.

What will happen between visits?

Your dentist will fit you with a temporary crown so that you can use the tooth whilst the permanent crown is being made.

How is the dental crown fitted?

Once you and your dentist are happy with the appearance and fit of your new crown, it is fixed in place using a special dental cement, forming a seal and holding the crown in place.

How long will my treatment take?

You can expect to have at least two visits. At your first visit your dentist will prepare the tooth, take impressions and shade information and fit the temporary crown; at the second the permanent crown will be fitted. In most cases there will be 1 to 2 weeks between appointments.

Will I feel any pain?

No, your dentist will numb the affected area using local anaesthetic, unless the tooth does not have a nerve, and a post crown is being prepared, in which case you may not need it.

Will the dental crown be noticeable?

Your dental crown will be custom made to match your other teeth as closely as possible, giving a natural looking result.

Will the dental crown feel different to my existing teeth?

As the shape of your crown will differ slightly to the tooth before it was crowned, you may notice a difference to begin with. Within a few days you should become accustomed to the new crown, and you will not notice it.

How do I care for my crown?

Properly cared for, your dental crown should last for many years. The crown itself cannot decay, however decay can begin from where the edge of the crown joins the tooth, so it is important to keep this area clean. We recommend that you brush for two minutes twice a day with a fluoride toothpaste and clean between your teeth with floss or interdental brushes.
