Sometimes known as a caps, crowns are carefully fitted sleeves that sit over an existing tooth to protect it from further damage, and to improve your overall smile.  

Crowns can hold cracked teeth together and support bridges, and they are often applied as the final step in root canal treatment. They can also cover discoloured teeth to improve the appearance of your teeth.

Why you may need a crown?

A crown is likely to be required if there is no longer enough healthy tooth tissue left to sufficiently hold a filling or used to cover and protect damaged or weak teeth. They can also improve the appearance of misshapen or discoloured teeth and act as protective sleeve which fits over your remaining tooth. A crown may also be placed as the final stage following root canal treatment, as this has proven to be the most successful way of sealing and protecting the tooth.

What's involved? 

Preparation time will vary depending on the condition of the damaged tooth. Your tooth will be carefully reshaped, to ensure that it can carry the crown. In most cases we will take a digital scan of the tooth. This is not only exceptionally accurate, but will also avoid the need for impressions to be taken, mitigating any discomfort. The scan is then received in our state-of-the-art digital laboratory where our team of technician’s use sophisticated computers to design your custom crown. These computers will then craft, mill and colour the crown to match the adjacent teeth. Treatment is usually provided over 2 visits. After the tooth is prepared and the digital scan is taken at the first appointment, a temporary crown is worn to protect the tooth for around 2 weeks while the crown is made.

What are crowns made from?

The application of crowns is one of the longest-standing dental procedures. We can date their use back to the 5th century and the ancient Etruscans, who used gold and silver to ‘cap’ problem teeth. Dental techniques have developed since then, and in today’s practices crowns can be made from a variety of materials:

  • Metal, including gold alloy and other metal-based alloys
  • Zirconia
  • Porcelain
  • Porcelain fused to metal (known as PFM)
  • Porcelain fused to zirconia
  • Ceramic
  • Resin

We recommend the use of porcelain crowns, as they are durable and can be crafted to match the natural shade of your teeth.

How long will a crown last? 

A permanent crown can last between five and 15 years, depending on your habits, lifestyle and oral care routine. Teeth grinding can put pressure on a crown, leading  to cracks and possible damage. If you know that you suffer from clenching or grinding, speak to your Hereford Dental & Implant Clinic dentist; they will be able to provide you with advice and possible solutions (such as a mouthguard) to help protect your crown and keep it looking its best into the future.

How shall I look after my crown? 

You can treat your crown like a normal tooth. While it does not require any particular care, remember that it acts as a sleeve over the top of your natural tooth and so decay and gum disease can still occur without a good oral health routine. Keep up regular visits to your local Hereford dental practice and remember to continue to floss around the tooth. When flossing, try to pull the floss through your teeth rather than upwards – sometimes pulling up and out can catch on your crown and contribute to wear and tear.  

If you think that you require crowns, or would like further information on the procedure, contact Hereford Dental & Implant Clinic in Hereford today.

What are zirconia crowns?

Zirconia crowns are a type of dental crown restoration that can be used to replace a missing tooth, or to even just improve the function/appearance of an existing worn down tooth. They will be quite often used in conjunction with other treatments, such as Dental Implants (for security/stability), Dental Bridges, or secured in place with a dental cement bond (over your existing teeth).

The compound material of Zirconia (Zirconium Oxide) is a strong type of ceramic which has been safely tested and proven to be used for humans. Zirconia can quite often be found in other medical areas, such as artificial joints, as it offers durability and a high strength.

Why would you need zirconia crowns?

The main reasons why you would need any type of crown is because of:

  • Losing a tooth or multiple teeth
  • To protect a damaged and weakened tooth (due to decay)
  • Covering a tooth with a large filling
  • Restoring broken/worn down teeth

What are the benefits of zirconia?

Zirconia Crowns offer the following benefits:

Strength – Zirconia offers high levels of strength over other types of crowns and will also last longer.

Aesthetics – They are not only made to function like a natural tooth, but they are also made to look beautiful and blend in with your smile!

Minimal tooth preparation – When fitting a Zirconia Crown there will be very minimal tooth preparation which means if the crown needs to come off at a later date, the original tooth will be better preserved.

How are zirconia crowns fitted?

With all dental crowns treatments, it will involve two stages:

Stage 1

We will measure (for new crown) and assess your teeth. Before anything happens your dentist will always explain what is going to happen so there will be no shocks and you will be in the know at all times. To prepare the tooth for the crown, it will involve minimal reshaping and a cleaning of the tooth.

We will need to take an impression of your teeth. This will involve a soft putty being placed in the patients mouth. The impressions will then be sent to the dental laboratory where they will fabricate the new crown.

Stage 2

When the crown has been made and sent back to us, we will be ready to fit it in your mouth. Depending on your exact treatment you are having, the crown will be fitted in your mouth (over an existing tooth, secured onto dental implants etc).

When we are fitting the crown we will always strive for the most natural looking and well placed position before we finally attach the crown. We will then give the crown a final polish, making sure the new tooth looks beautiful and blends in with your smile.

Please note that Zirconia crowns and other types of crowns all require the same level of attention and care that you would give to your own natural teeth. This will help prolong their life for a healthy smile.
