What are Dental crowns?

A Dental Crown or “cap” is a full cover that is custom made to fit over your tooth structure. A crown is permanently cemented to your tooth and doesn’t need to be removed. The aim of a dental crown is to improve the strength of a tooth that may be weakened due to a large filling, crack or break in the tooth.

Why might I need a crown?

There are several reasons why a tooth may need a crown

Broken tooth

If a significant amount of tooth structure has broken away, it can leave very little support for a filling to hold onto. Not only this, but the remaining tooth can often be weakened and prone to break further due to this reduction in support. A crown can help by increasing the support and protecting the remaining tooth and filling.

Tooth with a root canal or large filling

A large filling or root canal treatment will often mean a large cavity has been previously drilled in the tooth. This weakens the remaining structure of the tooth and leaves it prone to break further. A crown can help by increasing the support and protecting the remaining tooth and filling. In the case of root canal treated teeth it also improves the seal around the root canal treatment and reduces the incidence of failure significantly.

Dental Implant

A Dental implant is made of 3 components – the implant, the abutment and the crown. The crown sits on top of the abutment as the image below shows.

Cosmetic Crowns

Crowns can often be used for cosmetic purposes, if one or several front teeth are broken due to trauma, heavily filled, misshapen, damaged or discoloured. A crown can replace the damaged tooth structure, correct the shape of the tooth and improve the colour of the tooth it is placed upon.

What are crowns made of?

  • Gold Crown

    A Gold crown is made and cast completely from a gold alloy that averages about 50% gold content depending on the application, choice and cost.

    Advantages

    – A gold crown will very rarely chip or break away.
    – Requires the least amount of tooth reduction

    Disadvantages

    – Some people do not like the cosmetic appearance of gold crowns
    – More expensive due to gold alloy cost

  • Silver Crown

    A silver crown is made and cast from a non precious metal alloy.

    Advantages

    – A silver crown will very rarely chip or break away
    – Requires the least amount of tooth reduction
    – Cheaper than a gold crown

    Disadvantages

    – Some people do not like the cosmetic appearance of silver crowns
    – Not suitable if you have a significant metal allergy

  • Porcelain Crown

    Also referred to as “all ceramic” crowns. Brand names include eMAX, Lava.

    Advantages

    – The most life like appearance possible, making them ideal for crowns at the front of the mouth
    – Strongest adhesive bond to tooth

    Disadvantages

    – Requires more tooth removal than all metal crowns

  • Metal Ceramic or PFM crown

    This is a multilayered crown, on top there is porcelain which covers a metal substructure which sits against the tooth.

    Advantages

    – Cheaper than an all ceramic crown

    Disadvantages

    – Limited cosmetic appearance due to metal sub layer
    – Requires more tooth removal than metal crowns

The process of getting dental crowns

There are three main stages to consider when having a dental crown fitted. We will break them down for you so we can explain things clearer.

1. Preparation

First, you will need local anaesthetic and impressions of the top and bottom teeth as they currently are. These are used for the temporary crown and also as a record of the bite for the dental lab.

Then the dentist will prepare the tooth to the shape required for the crown chosen. This will involve some drilling of the outer surface of the tooth, to make space for the crown in the bite. The amount of tooth removed is roughly equal to the thickness of the type of crown selected.

Once the tooth is the correct shape, another impression of the tooth is taken which is also sent to the dental lab

Once this has been done, the original impression is used to create a temporary crown. This is made from an acrylic resin material. It is important to remember that this temporary crown will have the same shape of the tooth before the preparation is done. The temporary crown will also not be a perfect colour match.

The temporary crown is cemented with temporary cement and will not resist biting forces like a permanent crown. It is important to avoid hard, cruncy, nutty or sticky foods while the temporary crown is in place. This could cause it to fracture of lift off the tooth underneath. We also advise avoiding any strongly coloured food for 24 hours such as tomatoes and curries as this could discolour the temporary crown. Your dentist will advise you when the permanent crown will be ready, this can be anywhere from 1 to 4 weeks away depending upon the time it takes to construct the crown in the laboratory.

2. Fitting

The fitting is a much simpler process than the preparation. First, local anaesthetic will be delivered if required and then the temporary crown will be lifted off the tooth. Sometimes this will require a little drilling if the temporary crown will not lift easily.

Once the temporary crown is removed, the new crown is checked for fit. Sometimes minor adjustments are required. Once the crown fits well, the tooth is dried and a permanent cement is selected to seat the crown. Following this fitting, the bite is checked and adjusted with carbon articulating paper.

3. Aftercare

After straightening the teeth, you may find that the gumline is level but the edges of the teeth are uneven. This is due to teeth wearing down over time and it is easily corrected with a technique called composite bonding. We can use white, tooth-coloured composite material to bond to the teeth allowing us to reshape and balance your smile in a safe, minimally invasive way. However, this material does not change colour with whitening gel so natural teeth need to be whitened before composite bonding if this is desired. Whitening and composite bonding is included in our prices for Cfast treatment.

Although dental crowns may be one of the strongest restorations for teeth, they still do require consideration. We would recommend avoiding chewing sticky or boiled sweets as these could potentially “grip” the tooth on chewing and then on opening, lift the crown away from the tooth. It is important to note that like your own natural teeth, they can be susceptible to tooth decay and gum disease. Therefore it is important to follow good hygiene practices and keep the whole mouth as clean as possible. It is important to floss around all the teeth to prevent gum disease and tooth decay. We also advise reducing the frequency and amount of sugar in most diets.

How long will the crown last?

This varies depending on a number of factors, for example – the integrity of the tooth underneath the crown, individual gum disease and tooth decay risk factors. If well cared for they may last over 10 years if the tooth was of good strength previously. In some circumstances, for example if a post has been placed or there is minimal tooth structure under the crown then they may require replacement in less than 5 years.

Does getting a crown hurt?

This is a common question with many dental procedures. There are two aspects of the crown preparation and fitting to consider.

Firstly, at the fitting and preparation your mouth will be anaesthetised for the procedure and will be as comfortable as possible. In some circumstances, for example if you have had a root canal treatment, no anaesthetic may be required at all.

Secondly, some patients may find the impressions a little bit of a mouthful but these only take a minute or so each. It is important to just relax and breathe while the impression material sets, at which point it can be removed.

How much do crowns cost?

The cost of dental crowns can vary depending on if they are provided on both a private or NHS basis. The material selected also so we will discuss each of these options in the section below.

Private dental crowns

Private Dental crowns give you a full range of choice between all the materials currently available from gold to the most natural, cosmetically pleasing all ceramic crowns. Prices across practices can vary significantly as there are cheaper and more expensive private dental laboratories that can be used. At the Vallance Dental Centre we use both local labs and national award winning labs depending upon the case requirements.

Prices for private dental crowns start from £450, this doesn’t include any work required to the tooth beforehand, for example root canal treatment. To see our full list of dental charges click here. If you have dental insurance through work or a private scheme you may be able to claim some or all of the cost back.

NHS dental crowns

A dental crown through the NHS is a band 3 course of treatment. You will be limited to either a silver crown or porcelain fused to metal crown depending on the clinical circumstances. To see the current NHS banding prices click here.

    I've been with this practice for many years since moving to the Manchester area and I wouldn't want to go anywhere else! The receptionists are always really helpful and try to accommodate where they can.
    The dentists are especially good with my 4 year old daughter who was terrified of dentists originally but now happily jumps into the chair and puts on the glasses. We can always get family appointment times to suit us all together and it's never a long wait for an appointment for
    … More any treatment.
    Today I had some fillings performed by Darren and Pauline and they were brilliant - both very thorough, friendly and professional.

    My dentist is Amy, assisted by Catherine. They were both charming, caring and sensitive to my needs. I have multiple issues with my teeth, but Amy and Catherine put me totally at ease, and help me to cope. Amy is honest and kind in her approach to patients.

She is a professional who cares.

    Highly recommend Eesha and Catherine! They were exceptional on Friday. and much better than any hygienist I’ve tried. My teeth look fantastic and feel really clean, and he clearly communicated what he was doing at all times which really helped me to feel at ease. After he was done he took the time to give me some great tips on brushing/flossing too.🤝🤝🤝
