Dental Crowns in London

Dental Crowns London

Strengthen and restore your teeth with top-rated crowns in London
Dental crowns are caps of restorative materials that cover the circumference of the tooth crown (the visible part of the tooth in the oral cavity) to restore or strengthen it.
A specific amount of tooth structure must be removed to create space for the crown to be properly seated. Failing to achieve adequate room for crown construction can result in bulging crowns, which are deemed failures in terms of aesthetics and hygiene.

When do I need a dental crown?

Dental crowns are indicated in the following situations:

1. Restore the function and aesthetics of a badly broken-down tooth due to caries.
2. Strengthen weakened teeth after root canal treatment.
3. Restore function and aesthetics for fractured and cracked teeth.
4. Strengthen teeth with a large restoration.
5. Restore the aesthetics of a discoloured tooth when other conservative solutions fail.
6. Restore the shape of teeth with anatomical malformations related to their shape or size, such as peg-shaped lateral incisors.
7. They can be a part of other dental restorations, such as dental bridges, and can cover dental implants.

Types of Dental Crowns

Dental crowns can be fabricated from several materials. The choice depends on your preferences and the condition of the tooth.

1. Metal Crowns:

• They are fabricated from metal alloys such as gold, cobalt-chromium, and nickel-chromium base metal alloys.
• Metal crowns have very high wear resistance and rarely chip or break. They require a minimal amount of tooth reduction and can last a lifetime.
• The only drawback is their metallic colour, so they are typically used on back teeth, such as molars.

2. Porcelain fused to Metal Crowns:

• They are fabricated from a base metallic layer covered by a porcelain layer that matches your tooth colour.
• They can be used on both front and back teeth or when there is a greater need for strengthening teeth and improving aesthetics.
• They may cause wear on the natural dentition, the porcelain layer may chip or break, and the metal layer may exhibit a thin dark line at the margins.

3. All-porcelain (ceramic) crowns:

• Dental crowns are fabricated from porcelain or ceramic material exclusively.
• The ceramic crown may be milled as one piece from a ceramic block that matches your tooth colour using a CAD/CAM machine or by pressing an inner ceramic core to form a framework similar to metal, then porcelain layers are added.
• They provide superior aesthetics and a natural-looking appearance compared to all other types of crowns, as they mimic the natural translucency of a tooth.
• It can be used on the front and back teeth.

4. Acrylic and Stainless-steel Crowns

• Both acrylic and stainless-steel crowns are weak in terms of wear resistance, making them prone to pitting or fracturing easily.
• They can only be used as temporary crowns to protect the reduced tooth from sensitivity and fracture until the permanent crown is ready.
• Stainless steel crowns can also be used for children to protect weakened teeth and keep them in place until they shed.

World-class dental crowns at Dental Care Centre: Fabrication process

Need a dental crown? We’ve got your back. Dental Care Centre is London’s top clinic, offering high-quality dental crowns with superior function and aesthetics to meet your needs.
Dental crown fabrication requires two dental visits and takes around 2-3 weeks for delivery.

The First Visit: Examination and Tooth Preparation

Our prosthodontic experts will thoroughly examine the tooth designated for a dental crown. The existing restoration will be checked to ensure it fits properly with no open margins, and they will also ensure there are no active carious lesions.
In the case of root canal-treated teeth, an X-ray is performed to assess the root filling adequacy and to confirm the absence of any periapical infections.
If everything checks out, our experts will choose the most suitable crown material based on your needs, expectations, and tooth condition.
The initial step for crown fabrication is tooth preparation. If the tooth is still vital, local anesthesia will be administered to numb the tooth, and then the tooth structure is removed to create room for the dental crown.
After preparation, an impression will be made using a putty material or a digital camera. The impression will then be sent to the lab to customise your crown, with the chosen porcelain shade if all ceramic or porcelain fused to metal crowns will be fabricated.
As a final step, a temporary acrylic or stainless-steel crown is cemented to the prepared tooth until the final restoration is fabricated. A temporary crown is essential to prevent tooth sensitivity after reduction if your tooth is vital and to support your aesthetic and functional needs during your waiting period. Temporary crowns are weak and can be easily dislodged. Carefully brush and floss around the temporary restoration and avoid sticky foods. If the temporary crown is dislodged, contact your dentist immediately.

The Second Visit: Crown Cementation

The second visit is scheduled after the dental labs finish your permanent restoration. The temporary crown will be removed, and the tooth will be cleaned of any residual temporary cement.
The permanent crown is placed and checked for marginal fit, bite, and shade. If all aspects are satisfactory, a durable cement will be applied to secure your new crown.

Caring for your dental crown

Restoration with a dental crown does not guarantee immunity to dental caries. The margins of the dental crown are vulnerable to dental caries if proper oral hygiene is neglected.
Brush and floss your teeth regularly twice a day. Using antibacterial mouthwash may be beneficial in preventing plaque buildup at the crown margins. Avoid hard and sticky foods to prevent crown fractures or dislodgment.
If you are a bruxer, discuss with your dentist the need for a nightguard to protect your teeth and crowns.
Keep up with regular hygiene and check-up visits to maintain your oral health and prolong the lifespan of your dental crown.
