Dental crown: 5 Common Types of Dental Crowns

What are dental crowns? What Type of Dental Crown Should I Choose?  Your teeth have most likely deteriorated over time. Cavities, traumas, and other factors can all lead to tooth destruction. Your teeth may gradually lose their structure and function.

What are dental crowns?

Dental crowns, often known as porcelain crowns, are a coat that covers the visible area of the tooth. The form of each crown is determined by the original tooth. The benefit of porcelain crowns over metal-based crowns is an aesthetic component, since the replacement appears like the original, which is significant if you obtain the crown for your front teeth.

Why are dental crowns needed?

You may want to consider a porcelain crown if you:

  • Have you recently had a dental injury? Would you want to prevent a weak tooth from fracture or fix a cracked, worn-out tooth?
  • An anchor is required for a dental bridge to keep it in place.
  • Want to reshape a crooked tooth, to enhance your smile
  • To cover and support the teeth by replacing a filling that has gone loose or dropped out.
  • Have been treated with a root canal treatment.

Porcelain crowns’ role is to protect the tooth while also enhancing the strength and durability of an existing tooth.

What is the process of dental crown treatment?

Porcelain crown treatment often requires two appointments. Because your tooth has been prepped for the porcelain crown. The dentist will take X-rays of the tooth and the bone around it during the initial appointment. If there are any following problems, you may require root canal treatment:

  • Tooth decay.
  • Risk of infection.
  • Injury to the tooth’s pulp.

The dentist will next locate and remove any vulnerable areas of the tooth to give space for a temporary crown. If your tooth has lost too much of its structure, a filling can be utilized to expand your tooth before the crown covers it.

After the natural tooth is ready, a paste or putty is used to make a copy of the tooth. The copies will also be made for the teeth above and below the tooth that’s getting the dental crown. The involved impressions are to ensure that the crown will not interfere with your eating.

The impressions will be delivered to a laboratory. The crowns will be made in a laboratory, which usually takes 2 to 3 weeks. While you wait for the permanent crown, your prepped tooth will be repaired with a temporary crown before your next appointment.

The second appointment is generally within the following two weeks, during which your temporary crown will be removed and the permanent crown will be examined. If everything is in order, the gum tissue behind your teeth will be numbed and the new crown will be placed.

Dental crown treatment in one day. If your dentist has the required equipment, dental crowns can also be manufactured in the office. This operation is carried out in the same manner as the conventional method, beginning with the removal of decay and contouring of the tooth to guarantee a complete fit inside the crown.

Because permanent crowns are manufactured in a single day, the next stage is different from the previous technique. Scanning equipment (sometimes known as a “wand”) is used to obtain digital images of the tooth inside your mouth. These photos are analyzed by computer software, which creates a 3D model of the tooth. The computerized design is then sent to a second in-house machine, which cuts a ceramic block into the shape of the crown. This technique is known as computer-aided or computer-aided manufacturing (CAD/CAM). The crown is ready to be cemented into place in about 15 minutes.

What Type of Dental Crown Should I Choose? 

When you need a crown, you immediately consider the different types of dental crowns and their prices. This is because there are many different types of crowns available today, each with its own set of materials, costs, procedures, and patient requirements.

Some common types of crowns used in dentistry include:

1. Gold crowns

Gold crowns are actually made of copper and other metals like nickel or chromium. The main benefit of gold crowns is their durability and strength.

Some dentists may recommend a gold crown for back restorations, depending on the needs of each patient. However, due to their color and aesthetics, gold crowns are not a popular choice today.

Main ADVANTAGES of gold crowns:

  • They are strong and highly resistant
  • They last a long time if properly cared for
  • Less proportion of your natural tooth needs to be removed
  • They wear down quite slowly, just like natural enamel
  • They are ideal for posterior restorations (back teeth), especially second molars

Main DISADVANTAGES of gold crowns:

  • Poor aesthetics: They obviously don’t look like a natural tooth
  • Gold alloy crowns can affect some people and produce some side effects such as allergic reactions or swelling

2. All Porcelain Crowns

This is unquestionably the most popular type of crown today. They are completely made of porcelain.

  • Porcelain or ceramic crowns provide the best and most natural look.  They match your surrounding teeth in shape, size, and color.
  • The best option for front teeth restorations.
  • They are biocompatible: that means no metal is used, so they are toxic-free.

However, the main DISADVANTAGES of porcelain crowns are:

  • They are not as strong as metal crowns. Porcelain crowns can last a long time, but they have to be well taken care of.
  • Patients who suffer from bruxism should opt for gold of PFM
  • They may be more costly than other types of crowns, such as metal crowns.

3. Porcelain Fused-to-Metal Crowns (PFM)

Another popular type of dental crown is porcelain fused-to-metal (PFM) crowns. They offer both strength (due to their metal construction) and beauty (due to the porcelain coat that covers the cap).

The main ADVANTAGES of PFM crowns are:

  • They provide great aesthetics and durability
  • They’ve been around for over 50 years. We know they work well.
  • They are less costly than all porcelain crowns

However, the DISADVANTAGES of PFMs include:

  • Because of the metal in these crowns, there may be a gray line at the gumline. This may not provide the 100% aesthetically pleasing appearance that all porcelain crowns provide.
  • This type of crown may wear down more easily against opposing teeth in people who clench their teeth.

4. Zirconia Crowns

Zirconium is a new material that combines metal strength with the aesthetics of porcelain crowns. High translucent zirconia and layered zirconia crowns have recently become more popular.

The main ADVANTAGES of zirconia crowns are:

  • They provide great aesthetics
  • They are strong and long-lasting (less possibilities of chipping or breaking).
  • Because zirconia can be cut and shaped in the same dental office, the procedure can be completed in less time. It is not necessary to send them to a dental lab.
  • Zirconia Crowns are less likely to wear down due to their strength.
  • They are biocompatible: as metal free crowns, they are not likely to cause allergic reactions.

The main DISADVANTAGES of Zirconia Crowns include:

  • Their strength can make the teeth they bite against wear down easily.
  • Solid Zirconia can be difficult to adjust

5. E- MAX: Lithium Disilicate Crowns

The most recent type of crown in dentistry is known as E -Max. It is a lithium disilicate-based all-ceramic crown (which is also light and thin).

The main ADVANTAGES of E-max crowns are:

  • Great aesthetics. They look great in your mouth.
  • They can be durable and very strong.
  • They provide a great choice both for front and back teeth.

The main DISADVANTAGES of E-Max Crowns include:

  • They could be more expensive, especially to the dentist (who may or may not transfer that cost to you)
  • Some dentists have reported failures when using E-Max for posterior teeth, particularly when performing multiple units.

Comparison: Metal vs porcelain crowns

Cobalt-chromium, nickel-chromium, and other metal-based alloys are commonly used to make metal crowns. Metal crowns are well-known for their durability and have long been utilized in dentistry. When compared to porcelain crowns, they are the least likely to wear down, chip, or break. Because metal crowns are hidden, the majority of patients choose to have them placed on their rear teeth (posterior teeth).

Porcelain crowns are created to look like your natural teeth and are available in two varieties: all-porcelain and all-ceramic. Both are suitable for persons who are allergic to metals and may be used on both front and back teeth.

What Is the Average Cost of a Tooth Crown?

According to BeDental, the price range of dental crowns per tooth today can be as follows:

  • The cost of Gold crowns can range between $600-$2,500
  • All-porcelain crowns can range between $800-$3,000
  • Porcelain-fused-to-metal crowns can cost $500-$1,500
  • Zirconia Crowns and E-max crowns cost approximately the same as all- porcelain crowns

If you have insurance, approximately half of the crown may be covered. However, everything will depend on the type of insurance you have and your specific case.

If the crown is part of a cosmetic procedure, your insurance company is unlikely to cover the cost. However, if the treatment is preventative (such as a root canal or tooth repair), the cost may be covered by your insurance (or at least a percentage of it).
