What is a Dental Crown?
A dental crown is a fixed restoration that covers the tooth, replacing missing tooth structure. This allows your dentist to restore & protect many damaged or decayed teeth, while providing the look and feel of a natural tooth.
“Well made and maintained crowns can be some of the most durable and aesthetic dental restorations, providing long-lasting functional and cosmetic benefits,” says Dr Stephen Robinson.
Crowns are a versatile restorative treatment for a wide range of dental issues. These include –
- Cracked, damaged or worn teeth
- Large cavities & areas of dental decay
- Weak tooth structure (i.e. from multiple fillings in the same tooth)
- Restoration after Endodontic treatment (Root Canal Treatment)
- Protecting damaged teeth
Post-treatment – Porcelain crowns (1) used to replace older worn crowns,
with teeth whitening treatment to complement.
Why choose a Dental Crown?
Crowns cover most, if not all, of the tooth surface. This makes them a great restorative option for larger areas of decay or wear that cannot be treated effectively by a normal filling.
Dental crowns are made from robust materials, and this results in structurally sound restorations that can withstand the forces of biting. Crowns can be used to treat any of your teeth – from your front teeth to back molars.
They provide excellent aesthetics, increased strength and structure which makes them a great way to improve the look and function of a damaged tooth. Often, crowns are used to treat teeth that have sustained traumatic damage, such as chipping or breaking.
“There are many options for restoring broken down teeth, from the more conservative approach of a partial crown to a full crown,” says Dr Stephen Robinson.
What kinds of dental crown are available?
In modern dentistry, dental crowns can be made from a variety of modern dental materials that match your natural teeth, including a range of ceramics, such as E-Max.
“Crowns are fabricated outside the mouth which allows much stronger materials to be used than a dental filling. By working with our dental laboratory, we ensure that you are presented with a crown that has been made to the highest standards,” says Dr Stephen Robinson.
Other materials, such as metal alloys, are also available, and we discuss the benefits of some of the different types of dental crown below.
Ceramic crowns provide the best aesthetic benefits in modern dentistry, and naturally match or even improve your tooth colour, with variable cosmetic properties such as lustre, shade and translucency.
This style of crown is a great choice for highly visible areas such as the front teeth, or for people who dislike the look of other materials.
In PFM restorations, the outer shell is made of porcelain, which is underpinned by a precious metal layer that provides strength and structural stability. The result is a robust, yet aesthetically pleasing crown, with a strong substructure.
Gold crowns provide unmatched strength and durability.
These crowns are typically used to restore less visible teeth (e.g. back molars), and require greater strength because of the biting pressures exhibited in those areas of the mouth.
Full & Partial Crowns – Different Types of Crowns
Traditionally, crowns were made to cover the entire tooth, otherwise known as a full crown. This technique is still used today because of its capacity to provide excellent strength and provide a seamless aesthetic result.
However, modern dentistry has provided materials such as E-max (a type of ceramic) with different physical properties. These new materials can be used to create partial coverage crowns which restore and protect teeth while preserving more of the natural tooth structure.
While not every tooth is a candidate for a partial crown, the benefit of this approach is that your dentist can conserve more of your natural tooth structure. Your dentist can help explain your options when it comes to restorative dental treatment, and we recommend talking to your dentist about the different options available.
Do you have an ageing dental crown that you would like to replace? Your dentist can help you assess whether your crown has maintained its structural viability, and your options for bringing your old crowns back to life.
There are many issues that can impact the lifespan of a crown, including –
- Decay & gum recession
- Chipped or wear to the ceramic
- Movement and physical changes to nearby teeth (e.g. colour)
Your dentist will be able to inform you of these changes, and address the need to maintain or replace your dental restorations.
Aesthetically, many people wish to update the look of an older metal crown. These can be replaced with a substitute that matches the aesthetics of your natural teeth, and your dentist can explain the options available to you.
Your dental crown should be maintained like a normal tooth, and this includes brushing and flossing around your crown as per your normal routine.
After the placement of a dental restoration, such as a dental crown, your dentist will advise you on any specific maintenance recommendations. If you are having trouble accessing the areas around the crown, let your dentist know and they can help you find a way to approach the issue.
Care should also be taken when eating certain foods, particularly tough, hard or sticky ones that may accidentally dislodge or damage your crown.
A crown is often offered as a preferred treatment, over a normal filling, in places where the placement of a filling would leave the tooth vulnerable to further trauma, such as fractures.
For example, when a tooth has –
- Extensive decay
- Existing large fillings or restorations
- Weakened remaining structure
