Crowns

Dental crowns are a common and reliable solution in restorative dentistry, helping to strengthen weakened teeth, restore function, and improve appearance. A crown is essentially a custom-made cap placed over a tooth to protect it and ensure it continues to perform effectively in the mouth. This treatment is often recommended when a tooth has been significantly damaged or compromised but can still be preserved rather than removed.

‍

What Are Dental Crowns?

‍

A dental crown is a covering that is placed over an existing tooth. It is designed to replicate the shape, size, and colour of your natural teeth so that it blends seamlessly into your smile. Unlike fillings, which only repair part of a tooth, a crown covers the entire visible portion above the gum line. This full coverage makes it a durable and protective solution for teeth that are at risk of further damage.

Crowns can be made from a variety of materials, including porcelain, ceramic, metal alloys, or a combination of these. The choice of material often depends on the location of the tooth, its function, and aesthetic preferences.

‍

Why Might a Crown Be Needed?

‍

There are several reasons a dentist may recommend a crown as part of your treatment plan. Some of the most common include:

• Extensive tooth decay – when a cavity is too large for a filling to effectively restore.
• Fractured or cracked teeth – to hold the tooth together and prevent further breakage.
• After root canal treatment – to provide strength and protection for the treated tooth.
• Worn teeth – caused by grinding, acid erosion, or natural wear over time.
• Cosmetic purposes – to improve the appearance of a discoloured or misshapen tooth.

By restoring structure and function, a crown allows patients to bite and chew normally, while also protecting the underlying tooth.

The Crown Procedure

‍

Initial Assessment

‍

The process begins with a consultation and a detailed examination of the tooth in question. X-rays may be taken to assess the health of the roots and surrounding bone. Your dentist will determine whether a crown is the most suitable option or if another type of restoration would be more appropriate.

‍

Tooth Preparation

‍

If a crown is the chosen treatment, the tooth is first prepared. This involves shaping the tooth to create enough space for the crown to fit securely while maintaining a natural bite. In cases where the tooth has lost a lot of structure, a filling material may be used to build it up before crown placement.

‍

Impressions and Temporary Crown

‍

Once prepared, impressions of your teeth are taken to create a model. This ensures the crown is precisely designed to match your bite and appearance. A temporary crown is often placed to protect the tooth while the permanent crown is being fabricated.

‍

Placement of the Crown

‍

When the permanent crown is ready, it is checked for fit, shape, and colour match. Adjustments can be made before it is permanently cemented in place. Once fitted, the crown should look and feel like a natural tooth.

‍

Types of Crowns

‍

There are different types of crowns available, each with distinct advantages:

• Porcelain or ceramic crowns – These closely resemble natural teeth and are commonly used for front teeth, where aesthetics are most important.
• Metal crowns – Made from gold or other alloys, these are very durable and often used for back teeth that endure heavy biting forces.
• Porcelain-fused-to-metal crowns – A combination of strength and appearance, with a metal core for durability and a porcelain layer for a tooth-like look.
• Zirconia crowns – Known for strength and aesthetics, these are increasingly popular for both front and back teeth.

The choice of crown depends on the balance between function, durability, and appearance, as well as patient preference.

Caring for a Crown

‍

Although a crown is strong and designed to last many years, good oral care remains essential. To maintain your crown, it is important to:

• Brush twice daily with fluoride toothpaste.
• Floss carefully around the crown to prevent gum disease and decay of the supporting tooth.
• Avoid biting very hard objects such as ice or pens.
• Attend regular dental check-ups for monitoring and maintenance.

With proper care, a dental crown can last between 10 and 15 years or longer.

‍

Benefits and Considerations

‍

Benefits

• Restores the natural function of the tooth for eating and speaking.
• Protects a weakened tooth from further damage.
• Improves the appearance of a damaged or misshapen tooth.
• Provides long-term durability with proper care.

Considerations

• Tooth preparation involves the removal of some natural tooth structure.
• Crowns may eventually need replacement if they wear down or loosen.
• Good oral hygiene is essential to ensure the tooth under the crown remains healthy.

When to Seek Advice

‍

If you have a damaged, worn, or weakened tooth, or if you experience pain when chewing, sensitivity, or visible cracks, it is worth discussing crowns with your dentist. Early intervention often means better preservation of your natural tooth and less invasive treatment overall.
