A dental crown is a tooth-shaped cap that covers and supports a damaged, decayed or broken tooth.

Your dentist will numb the tooth and surrounding gum area and trim away any existing filling or decay to prepare the tooth for the crown.

They will also make impressions of the trimmed tooth and the teeth above and below it to ensure the new crown fits comfortably within your bite (‘occlusion’). They can be made from porcelain or metal like gold.

Strength

Dental crowns are able to withstand a great deal of pressure and this largely depends on the type of material it is made from. Metal crowns are the most durable option and can withstand biting and chewing forces for decades. However, they aren’t the most aesthetic choice due to their metallic colour and they can be prone to corrosion.

The strength of a crown also depends on the amount of natural tooth structure it must replace. A crown should ideally be anchored to the remaining core, so it can support and resist biting and chewing forces without dislodging.

The durability of a dental crown can also be affected by the habits of the patient, such as teeth grinding (bruxism) which can cause stress on the restoration and abrasion of the natural tooth. A regular routine of brushing and flossing can also help to maximise the longevity of a crown. Using a soft-bristled toothbrush and non-abrasive toothpaste can help reduce the risk of damage to a crown.

Durability

The durability of a dental crown depends on what kind of material it is made of. Typically, crowns are made out of ceramic or porcelain materials. These can be color-matched to the surrounding teeth for a natural look. They are durable and able to resist biting and chewing forces. They can also protect weak or fractured teeth from further damage or decay.

On the other hand, metal crowns are strong and long-lasting. However, they have a metallic color that can detract from the smile. They are best used for molar restorations as they can resist the force of biting and chewing.

Taking care of a dental crown is important to extend its lifespan. Good oral hygiene, regular dental checkups and avoiding harmful habits like teeth grinding can make a big difference. You should also avoid eating super sticky foods that can pull on the tooth and cause damage to the crown over time. The average lifespan of a dental crown is between five to fifteen years.

Aesthetics

Aesthetic dental crowns are meticulously designed to mimic the natural color, shape, and texture of teeth for a seamless integration into the smile. They also serve as a protective shell for damaged or weakened teeth, keeping them from further deterioration and reducing the risk of more invasive dental procedures in the future.

A dental crown’s aesthetics largely depend on the material it is made of. Porcelain and ceramic crowns are popular due to their natural appearance, while metal alloys like gold offer unparalleled durability. Composite resin crowns and acrylic resin crowns are also used for cosmetic enhancement, blending seamlessly with the smile.

Modern dentistry has revolutionized restorative dental care, with advancements in materials and techniques enabling both aesthetic and durable options. By carefully choosing the right treatment for your dental needs and committing to proper care, you can maximise the lifespan of your dental crowns. This includes maintaining a regimen of dental hygiene, which will ensure that your smile looks beautiful and healthy for years to come.

Comfort

The level of support and comfort you experience with your dental crown depends on the materials used and their design. Modern advancements in dentistry offer a diverse range of restorations that prioritize aesthetic perfection and longevity, as well as strength and durability.

Porcelain crowns are known for their natural appearance and are often preferred for front teeth. They are available in a variety of shades to closely match the color and optical quality of your natural teeth. Lumineers and porcelain-fused-to-metal crowns also deliver exceptional esthetics, while zirconia crowns are favored for their strength and biocompatibility.

After getting a dental crown, it’s common to feel some discomfort as the local anesthesia wears off. However, this usually only lasts a few days and can be alleviated with over-the-counter pain relievers. To minimize discomfort, you should stick to softer foods and avoid hot or cold temperatures for a few weeks after treatment. Additionally, you should continue to brush your teeth and floss regularly.
