Types of Dental Crowns: Materials, Uses, and How to Choose the Right One

Dental crowns are used to repair damaged teeth and replace the tooth’s outer layer. Many types of dental crowns are available today. They differ in strength, appearance, and longevity.

This overview will help you better understand when a particular type of dental crown may be used. Knowing the differences between them will help you choose the most suitable one for your needs.

What Are the Main Types of Dental Crowns?

The most common way to define types of dental crowns is by their material. The types below are the most common dental crowns in Turkey and other countries.

Metal Crowns

Traditional metal crowns are made from various dental alloys. This type includes gold, titanium, and cobalt-chromium crowns. Metal crowns are strong, even when very thin. They can be placed with minimal reduction to the tooth’s natural structure. They are also fracture-resistant and therefore suitable for patients who clench or grind their teeth.

Metal crowns do not look like dental enamel. Because of this, they are not used for front teeth unless requested.

In rare cases, patients may be sensitive to metal dental restorations. Metals also conduct heat and cold better than natural enamel, making them less suitable for patients with very sensitive teeth.

Metal crown

Advantages:

  • Exceptional durability
  • Preserve natural tooth structure

Disadvantages:

  • High cost for gold-containing alloys
  • Do not look natural
  • May cause sensitivity or an allergic reaction

Porcelain Crowns

Porcelain dental crown materials, such as lithium disilicate, offer exceptional aesthetic value. Porcelain crowns are the most translucent and look very similar to natural enamel. They are commonly used for front teeth.

Dental porcelains are harder than enamel, but less resistant to persistent stresses, closely resembling natural enamel. To avoid fractures, many types of porcelain crowns are made thicker and require more tooth preparation.

Types of Crowns

Advantages:

  • Exceptional aesthetic value
  • Biocompatible and inert
  • Poor temperature conductivity helps prevent sensitivity

Disadvantages:

  • Relatively high cost
  • Comparatively lower durability

Zirconia Crowns

Zirconia is one of the most durable dental ceramics. While it is not as translucent as other dental porcelains, it is much stronger and less prone to fracture. All-zirconia crowns are often used for posterior teeth. Unlike metal crowns, they are tooth-coloured, yet can still withstand the high pressure of chewing.

Layered zirconia crowns have a zirconia core and use another type of porcelain on top to enhance aesthetics. They are commonly used for front teeth when both structural integrity and aesthetics are highly important.

zirconium-porcelain-crown

Advantages:

  • High strength with good aesthetics
  • Requires less tooth preparation than porcelain

Disadvantages:

  • More expensive than other options
  • Can be difficult to adjust or remove due to their hardness

Porcelain-Fused-to-Metal (PFM) Crowns

PFM crowns use a metal core covered with a layer of dental porcelain. Once considered the “gold standard” for combining aesthetics and durability, they have lost some of their popularity to zirconia-based restorations, but they are still very common.

PFM crowns have some of the advantages of both metal and porcelain. They are most popular for restoring posterior teeth, where they help counter the aesthetic drawbacks of full-metal crowns while retaining most of their durability.

The outer porcelain layer, however, is less sturdy and can chip off with prolonged use. The edge of the metal core can also show under the porcelain if the patient’s gums recede.

Porcelain Crowns

Advantages:

  • Durable and relatively natural-looking
  • Cost-effective
  • Long and proven history of use

Disadvantages:

  • The porcelain layer can chip off the metal base
  • The metal margin can show beneath the porcelain
  • Require more tooth preparation than other crown types

Composite Crowns

These crowns are made from composite resins. The material is commonly used for fillings, but can also be employed for temporary or semi-permanent crowns. It is the least durable material for crowns, although it is inexpensive and biocompatible.

These crowns are used when the patient expects to replace them with another type of crown in the near future. Most commonly, they are used as temporary crowns placed before a more permanent restoration is fabricated in a dental laboratory.

Composite Crowns

Advantages:

  • Low cost
  • Good for temporary restorations

Disadvantages:

  • Low durability
  • Prone to staining
  • Low resistance to bacterial plaque formation

How Do Different Types of Dental Crowns Compare?

We can compare dental crowns using several criteria. When choosing the best dental crown material for your case, certain factors will be more important to you than others.

Aesthetics

The number of reviews we’ve received in Turkey regarding All-on-4 dental implants confirms that All-on-4 is the most popular implant system for full mouth restorations. This system consists of a full arch bridge and four implant posts. This is sufficient to restore all teeth in a jaw. Patient reviews highlight the system’s immediate loading feature. Tooth extraction and implant placement are performed in the same session.

MetalPorcelainZirconiaPFMComposite
Do not look like natural teethHighestHigh to very highModerateModerate to high

When comparing the aesthetic value of zirconia and porcelain crowns, porcelain is often regarded as more aesthetically pleasing. However, modern high-translucency zirconia can offer comparable results.

PFM crowns have metal cores that must be concealed with an opaque porcelain layer. This makes the crown look less natural than full-porcelain or zirconia restorations.

Composite resins resemble enamel, but are more prone to staining, which can reduce their aesthetic appearance over time.

Durability

All-on-6 systems have all the benefits of All-on-4, but provide increased stability for people who require it. All-on-6 uses six implant posts for each fixed bridge. The bridge uses aesthetic porcelain crowns. As such, the restored teeth look natural and are wear-resistant.

Our All-on-6 systems are made by leading brands. Any patient who chooses All-on-6 at our clinic can be sure that the treatment will be quick to install and recover from

MetalPorcelainZirconiaPFMComposite

In terms of durability, metal crowns are the least likely to fracture or chip. While they can be damaged, the ductility of metal means the crown will deform rather than break.

Zirconia is also very durable. However, in layered zirconia crowns, the outer porcelain layer is more prone to chipping than the crown’s core. The same applies to PFM crowns.

Tooth Preparation

Least reductionModerate reductionLow reductionHigh reductionLow reduction

When placing a crown, the dentist needs to remove some of the enamel to make space for the restoration. This is called reduction. The less reduction is required, the more of the natural structure remains in place.

Biocompatibility

Modern materials used for dental crowns are highly biocompatible. Only metal and PFM crowns require special consideration for the small percentage of patients who are allergic to certain metals. These allergies can be tested for if required.

Composite resins are prone to accumulating bacterial plaque, which can negatively influence gum health.

Which Type of Dental Crown Is Best for Each Tooth?

Considering the location of the tooth is very important when choosing a crown’s material. The biting forces experienced by anterior (front) and posterior (back) teeth are not the same, so they require different crowns.

Crowns for Front Teeth

Aesthetics are of primary concern when restoring teeth that are visible when you speak or smile. As such, porcelain and layered zirconia are commonly considered the most suitable as the best crowns for front teeth.

Front teeth are not used for chewing; accordingly, exceptional fracture resistance is not a requirement for crown longevity when treating front teeth. However, patients with bruxism benefit more from PFM and all-zirconia crowns, even for anterior teeth.

Crowns for Back Teeth

The best crowns for molars are those that can withstand high bite forces and look sufficiently natural. All-zirconia and PFM molar crowns meet both restorative and aesthetic needs.

All-metal crowns can be used if you are not concerned with natural aesthetics and want the most durable restoration possible.

Crowns After a Root Canal Treatment

If you have had root canal treatment, the treated tooth will need to be reinforced with a crown or inlay. If a crown is indicated, the dentist will rebuild the tooth’s core with artificial material.

After a root canal, rear teeth benefit more from PFM and zirconia crowns, while front teeth can be treated with porcelain crowns.

How Safe Are Dental Crowns? Risks, Sensitivities, and Long-Term Issues

Dental crown risks are mostly related to the chance of crown failure or sensitivity to metals used in the alloy. As far as general health is concerned, crowns are safe. Localised adverse reactions, such as gum irritation, are possible due to a poor fit or damage to the crown.

Allergic Reactions

Metal crown alloys can contain nickel or other metals that some patients are sensitive to. A non-metal crown, such as porcelain or zirconia, is recommended for such cases. A small fraction of patients can also experience allergic reactions to components of dental cement used to attach the crown to the tooth.

Decay Under the Crowns

Remember that while crowns themselves don’t decay, they can’t stop cavities from forming if bacteria reach under the crown margin. Good oral hygiene plays a key role in preventing cavities.

Teeth Sensitivity

Your teeth can become more sensitive to temperature after getting a crown. This is particularly true of metal crowns. This side effect is often only temporary, but if you already have sensitive teeth, it is better to choose a porcelain crown.

Improperly Fitted Crowns

Crowns that are not fitted carefully can negatively impact your bite or cause the opposing and neighbouring teeth to wear down more quickly. A follow-up appointment after crown placement can help ensure proper fit and prevent problems with dental crowns.

How Long Do Dental Crowns Last and How to Care for Them?

The lifespan of a dental crown depends on the material, placement in the mouth, and your overall oral health.

Crown Longevity

MetalPorcelainZirconiaPFMComposite
20+ years10-15 years15-20+ years10-20 years3-7 years

Crowns can have a shorter lifespan if you are prone to grinding or clenching your teeth or have a very strong bite.

These average crown lifespans presume that the patient maintains good oral hygiene and follows the dentist’s advice. This helps prevent cavities from forming under the crown margins, which is the main cause of crown failure.

Fortunately, caring for dental crowns is often very similar to maintaining healthy natural teeth, with some extra precautions to avoid damaging the restorations.

Dental Crown Care Recommendations

Dental Crowns in Turkey vs UK and USA: What’s the Difference?

Dental crowns in Turkey are popular among dental tourists. Patients travel to other countries when they cannot get a suitable appointment locally or to find lower prices.

Quality and Technology

The quality of crowns in reputable clinics in Turkey, the UK, and the USA is comparable.

Clinics in Turkey are more likely to use CAD/CAM processes for manufacturing crowns and tend to make them “in-house.” This computer-aided process allows a crown to be produced within 1–2 days, and sometimes during a single clinic visit.

In the UK, CAD/CAM processes are usually considered a premium feature and are more common in high-end private care.  Most clinics use an external dental lab for manufacturing crowns, which takes longer.

Cost

In terms of price, Turkish dentistry is more affordable than in either the USA or the UK. This is because living and labour costs, as well as rent and clinic overheads, are lower.

Generally, you can expect to pay the least for the same crown in Turkey, followed by the UK, and then the USA. The actual costs of dental crowns in Turkey vary between clinics and materials.

CountryPrice per crownTechnologyTreatment durationPackage deals

How to Choose a Safe Clinic Abroad

If you are considering dental tourism in Turkey, pay attention to patient reviews and choose reputable, well-established clinics. This will help ensure the treatment is safe and suitable for your needs.

How to Choose the Right Type of Dental Crown for You

How should you choose a dental crown that meets your needs? Start by considering the type of tooth that needs to be treated. Choose more durable crowns for molars, and more aesthetic options for the incisors and canines.

Consider your budget and whether aesthetics or functional restoration is more important for your needs. For example, the aesthetic differences between a PFM and a zirconia crown may be less important when restoring a molar.

The dentist can help you choose a crown during a consultation. Here are some questions that can help you and the doctor narrow down the best type for your case:

Frequently Asked Questions About Types of Dental Crowns

What Are the Most Common Types of Dental Crowns?

In modern dentistry, porcelain, zirconia, and porcelain-fused-to-metal (PFM) crowns are the most common. All-metal crowns were once ubiquitous; they are much rarer now.

Which Type of Dental Crown Looks the Most Natural?

Most patients consider all-porcelain crowns to look the best. Modern high-translucency zirconia is also very similar to natural enamel.

What is the Strongest Dental Crown?

All-metal crowns are the most durable, since they cannot crack due to the metal’s ductility. Zirconia is the hardest ceramic material commonly used for crowns.

Are Metal-Free Dental Crowns Safe?

Modern metal-free crowns are much more durable than they once were. They are safe and resistant to damage when correctly matched to the tooth.

How Long Do Dental Crowns Usually Last?

Most dental crowns last at least ten years. With good care, zirconia and metal crowns can last decades.

Which Crowns Are Best After a Root Canal?

Zirconia and PFM crowns are most widely used after a root canal. You can get a porcelain crown for an anterior tooth, but the decision should prioritise durability to prevent the tooth from cracking under pressure.

Can I Get Dental Crowns in Turkey Safely?

If you choose a reputable clinic, dental crowns in Turkey are as safe as those provided in your own country. Browse patient reviews and other information about the clinic and its dentists, including credentials, before-and-after photos, and videos of completed work, to make an informed choice.

What Factors Influence the Choice of Dental Crown Material?

The location of the tooth, your budget, your aesthetic expectations, and the required durability all influence the choice of material for your dental crown.
