A dental crown is used for damaged teeth. A cracked or broken tooth, for example, may require a dental crown. The crown is placed over the remaining tooth stump and cemented in place. Dental crowns are also used with dental implants, i.e., artificial tooth roots.
Here you will find further information as well as a selection of specialists and centers for dental crowns.
When is a dental crown necessary?
The question of when an artificial dental crown is appropriate arises whenever a tooth is no longer sufficiently stable. Patients need a dental crown when a large portion of the tooth structure has been lost, the tooth is severely weakened following root canal treatment, or there is a fracture. Another reason for placing a dental crown may be a very large filling that can no longer reliably stabilize the tooth in the long term.
In all these cases, a dental crown serves to protect the tooth, restore its function, and prevent further damage. The dental crown completely replaces the natural tooth crown and ensures an even distribution of chewing forces.
Dental Crowns as Dental Prosthetics
Dental crowns as dental restorations are considered fixed restorations and are placed either on a natural tooth or on an implant. Unlike removable dentures, they offer a high level of comfort and a very natural chewing sensation. The tooth is completely covered by the crown, so that the crown protects and stabilizes the visible part of the tooth.
What types of dental crowns are there?
The types of dental crowns available depend primarily on the material used, the tooth’s position, the load it bears, and aesthetic requirements. The type of dental crown is determined on a case-by-case basis. Generally, there are several variants that differ in terms of durability, appearance, and cost. The choice of material affects both durability and the final appearance.
Standard Crown / Solid Cast Crown
The standard crown is made of metal and is veneered with a layer of ceramic. The dental technician matches the color of the ceramic to the natural teeth. The crown is bonded to the tooth using a special cement, which requires the tooth to be significantly ground down.
However, a metal rim remains. It may well be visible, especially if the gums recede slightly over the years. In cosmetic dentistry, it is therefore recommended to veneer the rim of the crown as well. This is called a ceramic shoulder. These full-cast crowns are covered under standard benefits by statutory health insurance.

Veneered Crowns
A commonly used alternative is the veneered crown. It combines a metal core with a tooth-colored outer layer made of ceramic or resin. This gives it a more natural appearance and allows it to be used in visible areas. However, if the gums recede, a narrow metal edge may become visible.
All-ceramic crown
The all-ceramic crown is a particularly high-quality restoration; it is metal-free and well-tolerated and, as the name suggests, consists entirely of ceramic.
The color and surface texture can be precisely tailored to the requirements of cosmetic dentistry. In addition, the material reflects incoming light similarly to natural teeth, so that even on a front tooth, the crown is not noticeable.
In addition to standard ceramic crowns, zirconia ceramics are also used in cosmetic dentistry. They are particularly durable but require an additional veneer to achieve a natural appearance.
Ceramic offers more than just aesthetic advantages in cosmetic dentistry. The bonding technique used to attach the crowns (adhesive technique) means that very little tooth structure needs to be removed. As a result, more healthy tooth structure is preserved than with a conventional metal crown.
In cases of extensive damage, the specialist first rebuilds the tooth using a composite material. The tooth can then be crowned. This combination is designed to withstand chewing pressure over the long term.
Electroformed Crown
Another option is the electroformed crown. This is a ceramic crown with an ultra-thin gold cap. The cap is located on the inside, ensuring a very precise fit. This prevents a gap through which bacteria could enter beneath the crown.
The ceramic outer layer of the crown is, in turn, matched to the patient’s natural teeth in both color and surface texture. Experts in cosmetic dentistry frequently recommend this combination of materials.
People with allergies also do not need to worry about adverse reactions. In general, ceramic and electroformed materials can be used in cosmetic dentistry not only for crowns but also for full bridges.
Crown Placement and the Treatment Process
Crown placement refers to the complete covering of a tooth with a crown. Treatment with a dental crown involves several steps. The process begins with a thorough examination by the dentist. During this examination, the dentist determines whether the tooth is worth saving and which restoration is appropriate.
The tooth is then ground down and prepared for the crown. The goal is to create a stable tooth stump onto which the crown can be securely attached. Typically, the patient first receives a temporary crown to protect the tooth. After the crown has been fabricated in the dental laboratory, the permanent restoration is fitted and the dental crown is placed. Finally, the dentist checks the fit, bite, and function.
Depending on the extent of tooth structure loss, a partial crown may be used on the affected tooth instead of a full crown in order to preserve as much healthy tooth structure as possible.
Durability—How Long Does a Crown Last?
The durability of a dental crown depends on several factors, including the material used, oral hygiene, and individual wear and tear. On average, dental crowns last about 10–15 years. However, high-quality restorations can last significantly longer.
Cost of a dental crown—what does public health insurance or supplemental dental insurance cover?
The cost of dental crowns varies depending on the material, the complexity of the procedure, and the individual’s dental situation. Accordingly, the cost of a dental crown can vary significantly. It consists of the dentist’s fee and laboratory costs.
Statutory health insurance covers a portion of the costs through a fixed subsidy. Regardless of the material chosen, it covers a set amount based on the cost of standard care. For higher-quality materials, you’ll be responsible for a copayment. Supplemental dental insurance can significantly reduce this amount. The cost of the dental crown should be clearly outlined in advance in the treatment and cost plan.
Having a dental crown placed abroad may be less expensive, but it should be planned carefully, as follow-up care, quality standards, and reimbursement issues must be taken into account.
Frequently Asked Questions
When is a dental crown necessary?
A dental crown is necessary when a tooth is so severely damaged that a filling or partial restoration no longer provides sufficient stability. This is often the case with extensive tooth decay, after root canal treatment, or in cases of fractures.
What types of dental crowns are there?
There are various types, including the cast metal crown, the porcelain-fused-to-metal crown, and the all-ceramic crown. The type chosen depends on the tooth’s location, the forces it is subjected to, and aesthetic requirements.
How does the dental crown procedure work?
The process begins with an examination by the dentist. Afterward, the tooth is prepared, a temporary crown is placed, and finally, the permanent crown is cemented in place.
How much does a dental crown cost?
The cost of a dental crown varies depending on the material and the complexity of the procedure. Health insurance covers a fixed portion of the cost, and the out-of-pocket expense can be reduced through supplemental dental insurance.
How long do dental crowns last?
On average, a dental crown lasts 10–15 years. With proper care, they can last significantly longer.
