Dental Crown Treatment
A dental crown is a fixed prosthetic restoration that fits over a prepared tooth, making it strong and restores the shape, size and function of a natural tooth. A crown is sometimes known as a ‘cap’.
In case you have any concerns about dental crown treatment, please feel free to give us a call.
When Do You Need Dental Crown Treatment?
For a tooth that has been broken or weakened by tooth decay or a very large filling, a dental crown is a suitable treatment.
A crown could be used for a number of other reasons, for example:
- You may have a discoloured filling and would like to improve the appearance of the tooth.
- You may have had a root filling and need a crown to protect what is left of the tooth.
- It may help to hold a bridge or denture firmly in place.
What are the types of Dental Crown?
Different kinds of materials can be used in crowns, including:
- composite resin
When selecting the material for your crown, your dentist will consider factors such as:
- your tooth’s location
- how much of the tooth will show when you smile
- position of your gum tissue
- function of the tooth that needs the crown
- how much natural tooth is remaining
- color of the surrounding teeth
How Long Do Dental Crown Last?
The lifespan of a crown can vary between 5 and 15 years. Some crowns are made from a more durable material than others, hence a longer lifespan.
Typically, zirconia crowns were the least likely to crack or split. However, the outcome might vary due to crown placement and other factors.
Usually, PFM (porcelain-fused-to-metal) crowns and gold crowns are most likely to last the longest.
All-ceramic and all-porcelain crowns are more similar in aesthetics to a natural tooth, but they’re normally not as durable as the metal or PFM crowns. All-resin crowns are not as durable too.
With good care and maintenance, crowns can last for many years.
The Benefits of Dental Crown
Dental crown is a viable option for a range of dental issues. They are able to:
- Support a tooth that has been significantly damaged by decay.
- Protect a tooth that has worn away from being damaged further.
- Protect a tooth after a root canal procedure.
- Hold a severely cracked or broken tooth together.
- Cover a dental implant.
- Improve the appearance of a tooth by changing its shape or colour.
Dental crowns are a good long-term solution as they are durable and usually have a lifespan of 5-15 years.
Dental crown treatment has a high success rate compared to other dental restoration procedures. This is supported by various scientific researches on dental restoration techniques.
Dental Crown Procedure
Typically, you will need to make two dental visits for a dental crown treatment.
- The dentist examines and prepares the tooth that will undergo the crown procedure. This might involve taking X-rays of the tooth. They also may take a mould of your tooth or mouth in advance.
- Your dentist will file down and remove part of the outer layer of the tooth.
- An impression will be made of your trimmed tooth and the surrounding teeth.
- The dentist will put a temporary crown over your tooth to protect it.
- Your tooth impression will be sent to a lab that makes the crown. This may take several weeks.
- When the crown is ready, you will make a second dental visit and your dentist can cement the crown to your tooth.
Who is Suitable for Dental Crown Treatment?
Generally, there is no limitation on who is suitable for dental crown treatment. Hence, the risks and benefits of a dental crown should be evaluated for each patient to ensure the best option and procedure based on one’s oral condition and needs.
For example, a bridge with crowns is more durable than a removable partial denture when the purpose is to restore a missing tooth between healthy neighbouring teeth. However, implants are now the go-to option as they are considered a better but more expensive treatment than crowns as they do not make use of the healthy neighbouring teeth and there is a lower risk of infection beneath the bridge.
Therefore, if a patient can afford a dental implant treatment, this may be the better option. If the price is a concern, then dental crowns with a bridge may be the best option.
It is important to consider the purpose of the procedure and decide the appropriate course of action in the best interests of the patient.
