Dental crowns, popularly known as ‘caps’ are a prosthetic repair that covers the remaining portion of a prepared tooth, strengthening it and giving it a natural form.

When Do You Need Dental Crowns?

Dental crowns may be required in the following situations: 

  • To prevent a weak tooth from breaking (for example, due to disease) or to hold portions of a broken tooth together.
  • To repair a tooth that has previously been fractured or significantly worn down.
  • When there aren’t many teeth remaining, a big filling is used to cover and support a tooth.
  • To disguise crooked or badly stained teeth
  • Coverage for a dental implant
  • To make a cosmetic adjustment

 

What are the types of dental crowns?

Dental crowns may be formed from a number of materials, and new ones are developed on a regular basis. The following are a few of the most common choices. 

Porcelain-Fused-to-Metal Crowns

A porcelain-metal composite is the most popular restorative material for dental crowns and bridges. When porcelain and metal are heated together, the porcelain chemically bonds to the metal’s oxides, resulting in a long-lasting connection.

Because they are supported by a metal framework, porcelain-fused-to-metal crowns are more durable than ordinary porcelain crowns. They also match the form, appearance, and function of your original teeth.

Metal & Gold Crowns

Metal crowns come in a variety of shapes and hues. They form a strong connection, are resistant to fractures, and do not wear away teeth. Gold, copper, and other metals are commonly used in these crowns. Non-noble metals, which are highly robust and corrosion-resistant, are used in several metal crowns.

Crowns need the removal of tooth structure before they can be placed. Crowns made of metal need the least amount of tooth removal, making them a more conservative alternative.

All-ceramic

This cutting-edge method provides a metal-free option with the strength of a bonded crown and the aesthetics of a porcelain crown. As a result, it may be used in any part of the mouth.

Gold-alloy crowns

One of the earliest filler materials is gold. It is now combined with other metal alloys to improve its strength, making it highly durable. The colour of these crowns is silver or gold.

Stainless Steel Crowns (SSCs)

Only primary (baby) teeth are restored with stainless steel crowns. SSCs are used after pulpotomy or pulpectomy or also when huge decay is present on more than one surface of the tooth.

All-Resin Crowns

Metal, ceramic, and porcelain crowns are more costly than all-resin restorations. On the other hand, resin crowns are seldom recommended by dentists since they are more prone to fractures, wear and strain, and do not last as long.

Resin is a thinner, more delicate material than metal or porcelain for dental restorations.

 

What is the Procedure for fixing dental crowns?

First Visit — X-Ray, Tooth Reshaping, and Temporary Crown Installation

An x-ray of the patient’s jaw and teeth is taken first. Depending on the kind of crown, they then sculpt and contour the teeth. Metal crowns need the least amount of tooth removal since they are thinner. A temporary crown is put over the tooth after successful tooth preparation while the permanent crown is produced in a dental laboratory.

Second Visit — Permanent Crown

The temporary crown is removed after three weeks and the permanent crown is implanted. Your dentist will make sure the dental crown matches the color of your other teeth and fits comfortably in your mouth. Before the crown is placed, a local anaesthetic is given (only if the patient requests it). During the treatment, this drug numbs the treated region, ensuring that you are not in any pain. The crown is then cemented in place using a specific dental cement.

 

What are the possible problems you can face after having a dental crown?

Discomfort or sensitivity

As the anaesthetic wears off, your newly crowned teeth may be sensitive just after the surgery. You may have some heat and cold sensitivity if the tooth that has been crowned still has a nerve in it. Brushing your teeth with toothpaste formulated for sensitive teeth may be recommended by your dentist. When you bite down, you may experience pain or sensitivity, which indicates that the crown is too high on the tooth. If this is the case, contact your dentist right once. They can simply resolve the issue.

Chipped crown

Crowns constructed entirely of porcelain or of porcelain bonded to metal can chip. If the chip is little, it can be repaired using a composite resin while the crown remains in your mouth. This is typically only a short-term solution. The crown may need to be replaced if the chipping is severe.

Loose crown

Missing Teeth

Cement might wash out from beneath the crown on occasion. Not only does this allow the crown to loosen, but it also lets germs enter the tooth and cause decay. Contact your dentist’s office if a crown seems loose.

The crown comes off. Crowns can come loose at any time. The underlying tooth may have decayed, and the cementing material used to secure the crown may have loosened. Clean the crown and the front of the tooth if your crown falls off. Make an appointment with your dentist right away. They will offer you precise advice on how to care for the tooth and crown for the next day or so until you can be evaluated. If your dentist is unable to re-cement the crown in place, a new crown will be required.

Allergic reaction

Because crowns are generally made of a combination of metals, an allergic reaction to the metals or porcelain used in crowns is possible, although it is exceedingly unusual.

Dark line

Near the gum line, there is a dark line on the crowned tooth. It’s common to see a black line adjacent to the gum line of your capped tooth, especially if it’s a porcelain-fused-to-metal crown. The metal of the crown is visible through this black stripe. While not an issue in and of itself, the black line is unsightly, and your dentist may need to replace the crown with one made entirely of porcelain or ceramic.

 

How Long Do Dental Crowns Last?

Dental crowns typically endure between five and fifteen years. The amount of “wear and tear” a crown is subjected to, how well you follow proper oral hygiene practices, and your own mouth-related behaviours all affect the crown’s lifespan.

Does a Crowned Tooth Require Special Care?

While a crowned tooth does not need any particular attention, keep in mind that just because a tooth is crowned does not mean it is immune to decay or gum disease. Brushing your teeth at least twice a day, flossing daily — especially around the crown area where the gum meets the tooth — and rinsing with an antibacterial mouthwash at least once a day are all recommended oral hygiene routines to maintain.
